    • Tevo Little Monster + DuetWiFi + Touch7" (my conversion)

      This version of the printer is quite old. Now of the original printer remain just the glass and the top bottom frame (and parts of the skates).
      Substantially the original printer had too much tolerances and imperfections that make the tool unusable.
      Rebuilt everything with new and more qualitative part now it work.

      look also 3 post below for the rest of the description !!!

      This will take some time to explain with photos (i must still produce some of them) and descriptions... So for now I open the 3d.
      I'll use this post as reminder for me, to do not forget all the steps I made and , maybe , it will be useful for other adventurer decide to puts ends on a such big delta printer.

      1st and important... The Tevo company is terrible. I mean the back office for sure. In particular Kelly Zheng took 3 month for NOT send what she promised (and I paid). Paypal cover the funny joke.

      2nd... the printer for became something close an accurate tool need lots of work and money to put in.

      Inspirational :
      https://www.akeric.com/blog/?p=4325#Upgrades

      List of upgrade and modifications....

      Hardware:

      1. DuetWiFi + Duet LCD 7" (last firmware stable) + heat sink (with thermal pad T412) on parts could became hot.
      2. Nema motors 0.9 (for 3 motors + extruder) + dumpers + 4 12v noctua 6cm for cooling with lamptron fan hub (with resistance for lower the fan speed)
      3. Extruder (Bondtech)
      4. Original D3D Hotend + Volcano extension + copper nozzle (Nickel coated) + silicon cover.
      5. Original BLTouch v2
      6. Belts with iron core
      7. Full enclosure
      8. End filament guide/sensor
      9. Custom Borosilicate glass (41,5cm X 5mm) + adapters block (i'll provide the STL)
      10. Cartridge modified for better precision and less torque.
      11. Starting for the hot chamber solution... Double plexiglass (aluminum + double plexiglass + pvc + .... ) .

      Software:
      Slicer used ... Firmware Settings and so on...
      For now I'm using Ultimacker Cura and Matterhacker doing tons of test for the better result. The Firmware I'm using the last stable 2.02. And I'll try to explain why I used those settings.

      Filament used :
      At today I have used 3 filament.
      1)Formfutura Easyfill ABS
      2)Patona ABS
      3)Formfutura ApolloX (ASA)

      I can say the Easyfill ABS was pretty good but suffer as all the ABS of retraction and therefore warping.
      The Patona was pretty bad. Pop any time at any temp. Warping like hell. Cost half the Formfutura. But a shiny finish.
      The ApolloX is a ASA material that have less problem of warping of ABS at the cost of a little less beautiful finish (small percentage against the Easyfill).
      Less warping not mean none. So for object that have a big amount of layers ,placed as a corner , and a little surface of contact with the bed , you can experience some warping at the extreme corner. Any way very less than the other two ABS.

      1. The pouring of all the cable was not so fast as I imagined. I little scared of cook everything at the end i succeeded.
        I putted the two mobo close each other and with a laptop on the side started slowly to move all the cables using white plastic scotch to sign what i was moving.

      The two schema:

      With lots of patience I toke a very small screwdriver and moved the cables from the old connectors to the new duet ones. Some one have catted come plastic on the old ones and plugged on the new board but instead of this I preferred to use the connectors that can stay blocked when inserted.
      Other tricky stuff...the optical sensor have strange color wire. All different. So I looked at the schema and the polarity of the endstop (as in picture) and considered one endstop at ones as per se cabled.

      2)The nema motors 0.9 . I soldered all the cables and covered it with thermo sheath . Some hot glue for blcok the cables that enter in the motor.
      Applied a heat sink on each one with under a 3M thermal pad.
      Recovered from old back covers of some computer case , 3 metal plate. Of course drilled.
      Then I linked all the fans (also the mobo one , changed with a 12v one) to a 12v fan hub. And between of them I putted a potentiomenter for regulate the fan speed as i like. (the noctua at half speed are really silent).
      Between the motor and the support I applied the classical nema dumpers.
      I had to smooth the metal pivot (was full rounded) for a better block of the gears.

      1. The Bondtech extruer. I have to say the bowden connection is a little lose, so make sure you insert the teflon hose well to the end.
        I just added on the top a little piece of hose for a better guide and for a convenient calibration. (using the digital caliper im far enough to do not touch anywhere during the operation)

      1. Also if the chinese copy of the volcano D3D hotend was not that bad , I decided of put the original one. The TLM already have a volcano copy inside but with a small metal core and an old thermal sensor. All tensions are 12v.

      2. The original BLTouch v2 is slightly different. It have a sturdy shell despite the copy is a little more thin. The original trigger is in plastic and not in metal. The copy writing are a little more faded. The original one should be more accurate.

      3. Because of this article:
        https://www.reddit.com/r/3Dprinting/comments/61j9et/i_tested_some_gt2_belts_to_failure_on_a_tensile/
        alt text
        I choose to use the iron cored belts. They look more rigid but this absolutely dont impact in any bad mode to the movement. For Delta printer is suggested use those ones despite the standard ones just because the head is always in tension on the belts.

      7)As I started with the intention of build ABS parts i read about the necessity of build an enclosure for keep the worm.
      I used some aluminum bar . For the big windows I used 3mm plexiglass and for the smaller window I used the PVC material. All those parts , with the relative screw and rubbers are available in common DIY stores.
      For the small windows I tried to use the plexy but it crack for vibration and torsion.
      now with the black panels is more cool ^_^.
      For the closing mechanism I used dome adhesive magnet.
      I have done some holes on the top and bottom frame for block the corners that sustain the enclosure.

      8)End filament guide/sensor , it is well explained here:
      https://www.thingiverse.com/thing:2629228
      I just used the remix version for add the Teflon tube for a better guide and less friction.
      Just keep attention at wall close the mechanical sensor. The must be super flat and i added also some grease for a perfect slide.

    • RE: WiFi reported error : lost connection auto reconnecting

      @phaedrux

      The board is 2m in strait line in the same room of the router.
      "Intereference" ... maybe the fan (120mm) over the board? But is the first time happen and the fan is always the same as always.
      (I swear ones finished the enclosure I'll fix that mess of wires 😑 )

    • [solved] Several Newbie questions - porting fron RRF2 to RRF3

      Hi all,
      Hope some good soul can give me some advice . Finally I'm here on the RRF3 too. The 2.05.1 produce some strange errors. If I try to use the micro-steps suddenly the heater report fault. The height come wrong and the printer restart to print too hight or too low. Anyway lets go on..
      I have installed the RRF 3.01.rc12 . Paneldue 7i updated at 1.24. Web control to 2.1.7. DuetWIFI rev 1.02
      Delta printer as 3D printer.
      I tried to dig in guides and https://www.reprap.org/wiki/G-code but I still miss to many stuffs.
      https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_Summary_of_what_you_need_to_do_to_convert_your_configuration_and_other_files

      1)EDIT: Where I can found the real PIN names of the board?(schema or list). I thought they could be the names of the board diagram but they are not.Ex: for bed thermistor I expected "thermistor0" instead seems to be "bedtemp". So for sure I copy-pasted wrong names everywhere.
      Ok I was blind/fuse, found the list...hemm...I'll try to read better.

      2a)EDIT: The PanelDue 7i didn't show any temp despite the webcontrol does (also if wrong values) . No nozzle heater , no bed heater , no chamber heater , no extra heater added.
      Reading is a good practice: https://github.com/dc42/RepRapFirmware/blob/v3-dev/WHATS_NEW_RRF3.md
      Added to the M575 P1 S1 B57600 to config.g and the IAP.bin make the PaneDue work properly., Before was stuck on "connecting".

      2b) EDIT: I added a 4rth thermistor (as shown in the config.g) . How I can map it for RRF3?
      Reading the correct PIN name and M308 and M950 functions make me to insert the right value.

      2c) EDIT:The thermistors , except for the bed that is right, reports wrong values also if old setting are used. 100degree instead near 25.
      Basically the wrong setting leave report wrong values.
      Now this code work good for the heaters all.

      ; HEATERS :
      M308 S0 P"bed_temp" Y"thermistor" A"Bed" T100000 B3950 ; define bed temperature sensor 
      M950 H0 C"bed_heat" T0 ; heater 0 uses the bed_heat pin, sensor 0
      M308 S1 P"e0_temp" Y"thermistor" A"Nozzle" T100000 B4725 C7.06e-8 R4700; define E0 temperature sensor for nozzle
      M950 H1 C"e0_heat" T1 ; heater 1 uses the e0_heat pin and sensor 1
      M308 S2 P"e1_temp" Y"thermistor" A"H_C_Resistor" T100000  B4725 C7.06e-8 R4700  ; configure sensor 2 as thermistor on pin e1_temp for hot chamber 
      M950 H2 C"e1_heat" T2 ; heater 2 uses the e1_heat pin and sensor 2resistence
      M308 S3 P"e2temp" Y"thermistor" A"Enclosure" T10000    ; configure sensor 3 as thermistor on pin exp.35 for enclosure
      ;M950 P3 P"exp.heater3" T3; sensor 3 uses the exp.35 pin and sensor 3
      M140 H0 ; the bed heater is heater 0
      M141 H2 ; heater 2 is the chamber heater
      
      

      3)EDIT: Fans I would reach: FAN0 (connection on the schema) is for the nozzle in thermostatic mode. FAN1(connection on the schema) is for cooling the printed part and should be used by the slicer or manually controlled. FAN2 (connection on the schema) I would leave it manually for the hot chamber with a minimum of 30% on.
      As for before with the proper PIN names all came to work.

      4)EDIT: Endstop? If I try to home nothing move.
      They work fine:

      ; Endstops
      M574 X2 S1 P"xstop" ; Set active high endstops
      M574 Y2 S1 P"ystop"
      M574 Z2 S1 P"zstop"
      

      5)EDIT: Smart effector? I copy pasted , but of course I don't know if is right.
      It seems to work.

      6)EDIT: Filament sensor? Still as above how to map it?
      No error report but still to be tested

      ; Filament Sensor - Add the following to config file anywhere before the M501 command
      M591 D0 P1 C"e0_stop" R20 S1; configure extruder drive 0 to use E1 endstop (C4) with 20% tolerance , new extruder settings for filament sensor
      

      7)EDIT: The TOOL section have the fan reverted (nozzle - cooling part) but now I don know if this is still necessary because the new mapping system. In the case how to do that again?
      The exchange between the nozzle fan and tool fan is still valid.

      THANKS TO ANYONE WILL CONTRIBUTE 😀

      As told I added the top insulation.
      And also added some clip because now the sponge create too much pressure on the magnetic closure.

      Ok,
      Also I suggest you to verify those alignments.
      Those must be at the same equal distance.
      Doing this I reached that the X and Y of M665 are gone from several decimal to some cents.
      In those trap we must gain as much precision everywhere 😰
      In my case for obtain the more possible equal distance , I was not able to keep the tower aligned with the top frame.

    • RE: Thermistor's shows 2000°C ( Slolved )

      Ok Thomas.
      Deck is right , you are using the v2 firmware with v3 settings.
      For upgrade the firmware from 2 to 3 you have to make before 2.xx.x>3.0 then 3.0>3.1.1
      If you have the panel due don't forghet to add this line on top :
      M575 P1 S1 B57600; enable panel due to connect properly
      Here all the info:

    • RE: [not yet solved] Tevo Little Monster DuetWifi errors

      Dear absolute !!!! Maybe you nailed it ! 🕵

      Look at this , the six rods:
      1> -0.25
      2> -0.25
      3> -0.15
      4> longhest
      5> -0.1
      6> -0.6 !!!!!!!!!!!!!!!!!!!!
      Poor auto calibration , It cant reach those parameters. 😱

      From the Duet guide (and your linked pdf too):
      https://duet3d.dozuki.com/Wiki/Calibrating_a_delta_printer
      All 6 rods must be the same length, measured between bearing centers

      If you are building the rods yourself, make them one by one in the same jig. If you are buying them, check that the supplier guarantees a maximum difference in rod length, which should be less than 0.1mm. It is particularly important that the rods in a pair are of matched lengths, because any difference will cause the effector to tilt.

      I lost damn ages because I trusted the manufacturer 😵 REALLY My BAD 👶 ... I had should check this hundred time before all the attempt I made for calibrate it.
      My mistake was : the product is already made , it will be good. 😥 Such a sheep.
      20200117_160547.jpg 20200117_160602.jpg

      Now what? Buy hundred of them to make sure found SIX equal ?!?!?!?!? Damn Tevo.

      I feel so bad for wasted your time... All the people had helped here , damn ... sorry.
      I should had to think as the printer was made by me and check ALL the steps as reported in the guide. Inexperience here docet.
      Now I'll go check all the rest of the hardware hoping that the frame didnt have absurd variations 😔

      I'll keep you informed about the evolution of the story...

    • RE: Strange Blobbing on Layer Change

      @davidewen
      Yep the Z in M566 could be higher. Right now I have just a delta printer and settled 800 on all 3 axis.
      You have 900 on x and y. Why so slow on z with just 60?
      David suggest the default as 600 in this post:
      https://forum.duet3d.com/topic/310/m566-what-s-a-good-number
      But someone use even 1200.

    • RE: Strange Blobbing on Layer Change

      @davidewen
      Hi Davide,
      Maybe you are super skilled already with all those programs , I'll just try to be cooperative.
      Is a little hard to tell for sure regarding just one possible solution.
      I use Cura and I can try suggesting something using it.

      • Try to use Cura 4.13.1. The 5.X series address some issue with concentric shapes (the width of the lines) and is removed the function of exclude tiny gaps, resulting in additional movement and extrusions. (maybe is not the case but on circular shapes could help the first point).
      • Try to use defined seam. (so , not the shortest nor the random or sharpest) . In the preview look for the best position where to place the seam. (back , front, left etc) . Try to obtain on vertical line as seam. If necessary rotate the shape. (Cura is rotation sensitive , and you can discover it looking the support lines)
      • Try to work on Wall > outer wall wipe distance. (should help to hide the seam inside the shape)
      • Try to work on Travel > disable retraction at layer change (this avoid pause and leak of materials because the pressure)
      • Try to work on Travel > combing mode on all (less retraction > less pressure changing > less leaking)
      • Try to work on Travel > disable retraction before outer wall
      • Try to work on Experimental > enable coasting . Here work on the number of the area of the nozzle. (moving without retraction should reduce the amount of material leaked for the variation of pressure. If you exaggerate with this option , or the sum of all those settings, you could generate holes instead of blobs).
      • Keep in mind that if you change layer height , all those parameters will change. To my printer ,to print at 0.3 or 0.2 is not absolutely the same.
        And you have seen by yourself with the first shape on left that emphasize the issues.
      • Keep in mind that not all the shape can use the same profile.
      • The concept is to try to avoid the numbers of retractions and keep the material's extrusion the more constant you can.
      • Then... is not exactly clear from the picture , because there are not 90 degree corners , check the belt tension. On quick and fast direction's change you can have a little of vibration of the nozzle. Or instead do not exaggerate with the speed of the print.

      I tried to inspect your picture , thanks for the high resolution.
      The lines seems good except for the seams.
      I'm optimistic that you can nail the right combo of settings.

    • RE: Tevo Little Monster scratches print

      @manuel
      Hi ,
      At this page you can find the delta printer calibration full explanation:
      https://duet3d.dozuki.com/Wiki/Calibrating_a_delta_printer

      If you are sure about the numbers that you added (thickness of the glass) you can just modify the "System > config-override.g" file in the M665 line at the H parameter (subtracting the mm you added).
      If this will go fine you can change the H parameter also in the config.g

      In general for see the height of the printer:
      1- power on the printer
      2- home the printer
      3- lower the head till the glass
      4- when you are at the zero send in console G92 Z0 (to define the new zero level)
      5- home the printer and read the new height value in the duet dashboard (Status > Z position) after the endstop are triggered. Keep in mind that the home position is lowered of 5mm (you can find your value in the homedelta.g , so you have to add also those mm to the height value you read in the Status > Z position.
      6- write this new height in the config-override.g (and config.g)

      If you dont have changed also the nozzle height modifying the head of the printer , should be enough adjust the height as above.

    • RE: "G28 Error: G0/G1: insufficient axes homed" after months of use

      @ignacmc
      Hi,
      If you didn't touch anything (and before was working) it sound as the endstop are not read correctly.
      Try to clean all of them. Look if the red light are operational.
      Have you checked all the endstop? Try a singular independent move to see if all of them work regularly:
      Testing the motors and endstops individually
      https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareDeltaPrinter#Section_Testing_the_motors_and_endstops_individually

      Not related now because you receive the error soon as you try to move, but it could be useful in future: When the head was placed on the extreme part of the bed and try to home is also happened that in the home.g this line had the X Y Z parameters too small and received your same error:
      ; Move all towers to the high end stopping at the endstops (first pass)
      G1 X640 Y640 Z640 F2500 H1

      I'm at shortage of other ideas... hope some more expert can provide more suggestions 😊

    • RE: Smart Effector setup issues

      @incidrthreat
      Hi, I have a delta so I'll try to be useful...
      The error that is blocking your right probing is this , in "config.g":
      Rnnn : Radius to probe

      M557 R90 S20                                        ; define mesh grid
      

      The R parameter MUST be bigger that the value (radius) you set in http://www.escher3d.com/pages/wizards/wizardbed.php bed generator.
      Now , as you wrote , they are coincident so they come skipped.
      Your radius is 140 so try M557 R120 S20 instead.

      Then, cosmetic stuff... I suggest you to erase the G31 line in the config-override and work for the zprobe in config.g for don't make splitted code. And leave geometrical and other auto-calibration in the override.

      1)In config-override (remove this line and work in config.g):

      ; Z probe parameters
      G31 K0 P500 X0.0 Y0.0 Z-0.31
      

      -What is in G1 "K0" for? in the wiky https://www.reprap.org/wiki/G-code#G31:Set_or_Report_Current_Probe_status it is not mentioned.
      I dont know if this can generate errors somewhere. Remove it.
      -Try to set "Z-0.1" till you are not certain that all work as it should. Then you'll refine the stuffs.
      -P500 . For the smart-effector this line is suggested G31 P100 X0 Y0 Z-0.1. (look at commissioning)
      https://duet3d.dozuki.com/Wiki/Smart_effector_and_carriage_adapters_for_delta_printer
      https://forum.duet3d.com/topic/16758/g31-trigger-value-what-is-it-good-for?
      =1641345568624

      2)In config.g ,despite it come bypassed by the config-override.g ,change the Z from 5 to Z-0.1. 5 mean to fly too hight for the head.

      G31 P500 X0 Y0 Z5
      

      For the smart-effector this must be "P8" not "P5"...

      M558 P5 R0.4 C"zprobe.in+zprobe.mod"
      

      For the axis limit set a negative value so that if your Z0 is too high (for some reason) and with babystep you have to go really close the bed , you'll can. Set it ex at Z-0.3.

      ; Axis Limits
      M208 Z0 S1                                          ; set minimum Z
      

      After you made those change to the code:

      -power off , power on the printer.
      -home (G28)
      -run a single probe (G30). (it will be slow)
      -keep the right height and write it in the override.g M666 H parameter.
      -restart the printer
      -run at least 3xG32
      -in console type M665 for read the actual value and copy ONLY the R in the ovverride.g. (and leave the M666 to 0 for all the items)
      In this way you will leave to the auto-calibration the job to recalculate the other parameters. In my experience if you put too much manual settings and they are not perfect , the result come even worse.
      So basically for the M665 you can add manually : rod length , radius (after at least 3 calibration) , height.

      It's late here in Italy... I dont' know if there are more errors in your files... but I'll collapse .... try those change and let us know 😀

      And also check the wires , just in case. Can happen that if the movement of the head modify the tension of the cables , in some area of the bed the contacts could be not perfect.
      Plus, if is it possible don't calibrate with everything too hot (bed and nozzle) , can occur inconsistency trigger read .
