@Corexy It's surprisingly useful sometimes to have a finger that size and shape, but I'll leave that to your imagination...... It kind of matches the lump on the back of my other hand caused by a badly set "boxers fracture" but I won't be explaining how I got that either.........

@TC I don't / can't use that feature because my tools use multiple extruders. But as far as I can tell from here https://duet3d.dozuki.com/Wiki/Filaments, you have to load one filament into each tool then that loaded filament gets save into "/sys/filaments.csv". Maybe you could achieve what you want to do by editing that .csv file???

@blt3dp said in Hemera settings for Reprap Firmware?: The retraction could be a little more, I have a 650mm bowden, but barely any stringing. Or i could possibly tune pressure advance instead. Ah, so it's a bowden Hemera. That makes a huge difference. I would imaging the settings for a Titan or Bondtech extruder with a similar bowden tube length would work well, because all 3 of those extruders have about 3:1 gearing. These are the settings I use on my delta, which has a 600mm Bowden tube and Bondtech extruder: M201 X3000 Y3000 Z3000 E1000 ; Accelerations (mm/s^2) M203 X15000 Y15000 Z15000 E3600 ; Maximum speeds (mm/min) M566 X600 Y600 Z600 E600 ; Maximum instant speed changes M572 D0 S0.2 ; pressure advance Higher pressure advance might be better, I haven't optimised it. I have retraction set to 6mm. Extruder acceleration could probably be increased. HTH David

@bondus looking the video, I think at this position the actuators need a lot of force *)because the angle at the hotend is very big, near the singularity. Precision in left-right-direction will be low also. High microstepping means low torque which may explain the 256-128 difference. If you move the hotend further away, it will be more precise imho. I mean the forces need to be high for a movement from right to left.

@Phaedrux ok thank you, will also change that and see how it goes thanks to everyone for suggestions, will keep you up to date

@Corexy said in Large corexy mechanical kit options: ............To be honest I'd like to switch off all leveling, or at least have it that it only needs the mesh updated if I change/move something. Yup - that's how mine is and it's so nice to be able to turn on the printer, select a file and hit print. My slicer start code calls a macro which heats everything up and runs home all but that's all I ever do. I've never used any form of firmware levelling or flatness compensation - being a mechanical engineer (retired) I always prefer the mechanical solutions. At the last TCT show, I took the XYUVAB assembly off the base which is the Z axis, put the bits in a van, transported it 60 odd miles, carried it to the stand, put it back together, set the Z offset (because I have to remove the Z axis switch when I take the the printer apart) and started printing. Didn't even bother to check that the bed was level. Did the same in reverse but when I got back home I did re-check the bed level - no adjustment required. Job's a good 'un.

@Phaedrux said in weird behavior, uploaded G-Code looks like binary: @arhi said in weird behavior, uploaded G-Code looks like binary: I sent M112 to the board and I got "Emergency stop trying to reconnect" I think you might have sent M122 instead, which is a reset. 5AM, EVERYTHING is possible I'll retest more carefully in the morning. I've never seen anything like the upload behaviour though. What firmware and DWC version? I reproduced the behavior 3 times. Please download the original file and try to upload to your duet2eth and then download back from duet. I'll do more debugging tomorrow (new card, other big files etc.). I'm using firefox but I doubt that's important since I got exactly the same result with CURL Duet Web Control 2.0.7 Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.01-RC2 (2020-02-18b1)

@msjfb said in Mesh leveling: should we see the Z axis value change in DWC?: I am now moving to another issue: with mesh correction active, how to adjust the actual distance between the nozzle and the bed when printing with different materials for instance: higher up for PETG, and lower for PLA for instance. I have started testing , and I need to search this forum a little more, but I will probably open a new topic for this. There's a few ways. You can use babystepping at the start of the print to adjust the Z height up or down by small amounts manually. You can set a Z offset in the slicer. There's usually an option to add a small amount for the first layer. For what it's worth though, I never actually do this anymore. My first layers are always the same, regardless of material being printed. I print on heated PEI and the only thing that changes is the temperatures, and for PETG I add some glue stick as a release agent. The first layer is always 0.2 and the extrusion width is always equal to the nozzle diameter and 30-35mm/s. The PEI is pretty flat but I do a detailed mesh compensation anyway and the first layer is always spot on, no offset or over extrusion.

@dc42 Will do. I am on travel so it may be a few days but happy to post a file with the issue when I return.

@dc42 I came across a minor issue in 3.01RC2 (tested on DuetWifi). The gcode line numbers do not reset each time M32 is run, so a gcode file that contains conditional gcode errors will display the incorrect line number if it's not the first one run since reset.

yikes

@IngPaoloFrancia said in Unable to correctly configure througt RRF config Tool: Can someone help me to get the right configuration? With the infos you provide: no. Your schematics are inconsistent with the instructions below. These state to use separate drivers for each of the Y- and Z steppers, whereas the schematics advise you to wire them in series - which, for NEMA 23, is complete nonsense. Then, why should you use two X end stops for just one X stepper? Oh, and no end stops for Y? Finally, I guarantee that the RRF configurator will not work as expected, given the weird connection scheme, it will never produce the „expected display appearance“ shown in your docs. For such a printer, you will need to dive deep into the realms of Gcodes, you will have to write large parts of you config.g manually, and you should carefully commission every single stepper, heater, and end stop. This includes a firm knowledge of the Duet’s ports and their respective assignments in Gcodes. For the hardware, please refer to these pages: Duet 2 Wiring Diagrams Duex Wiring Diagrams Depending on what your skills are, you might want to get an overview by reading the Step by step guide to using your Duet 2 There, you find numerous links how to connect your steppers, how to get connected, how to use DWC, how to update the firmware, how to wire your Duet, … Within this document, you will also find sections for initial configuration and commissioning tests - I strongly advise you to read them thoroughly. An overview of the RepRap Firmware is given here, with numerous links to setup guides. You will need them. By the way, you currently have the choice between RRF 2 and RRF 3. My personal advice is to stay with RRF 2 for the moment. You will find the latest stable release here. For Gcodes and how they work, you should always have this reference at hand. ––– Sure, this forum will try to help if you run into trouble. When you are familiar with the basics, your questions will be more specific than now, and chances are high that we find a solution. So, please read and understand. Then, I’ll hope to see you back here.

Here is the results: console.txt and this after i checked that the board and the panel are on the same baud speed setting. how would i issue a restart or reset of the board and panel.

@dc42 Sorry to keep bugging but I cant rap my brain around this. So from where I have my computer attached to my CNC the far back left corner is where the X and Y end stops are located. So when i homeall everything goes to the far left back corner and the Z axis moves as high as it can till it hits the endstop. Everything on the DWC shows 0.0 for alignment. However because of where the computer is located i would like to line up my material from the close edge. So I am trying to use the far left close edge as my X0 Y0 points. I line up the spindle to my starting point hit my G10 L20 P1 X0 Y0 Z0 command then I try to run my cut and I get G0/G1target limit outside of machine area. I know it has to do with negative and positive numbers but just confused as to what needs to be what.

@Danal Yes, they are both where they should be now. Like I said, they used to work then all of a sudden decided not to. I did do PID tunes a bit ago. I will try heating again in a bit. I have 7 other FDM printers but all Marlin so this is new to me even though I've had it a few months. Thank you for the help thus far. I just have to figure out what to change to get the bed to home in the correct direction now.

The 64 is somewhere between the 128 and 32. It looks like the driver does something useful with the finer stepping. I would guess that for static resolution it is pointless to go over 16, but when constantly moving the drivers can do something useful with the extra step information. It would be interesting to test this out on a delta, or a regular scara. It might only be visible with the low gearing I have though. The engineers at TMC are magicians.

thank you so much for your help, yes exactly I'm going to mount everything in corexy, and start to prepare everything for the additional chario. I have only 2 stepper motor for z, so duet2 wifi 5 motor available, I need the extension duex5 in my opinion as its I would be good to add the 3rd stepper motor on z, and I add my missing extruder for chario idex, and i will be ready for the future i think merci énormement pour votre aide, oui exactement je vais tout monter en corexy, et comencer a tout preparer pour la chario suplementaire. j'ai que 2 moteur pas a pas pour z, alors duet2 wifi 5 moteur disponible, il me faut l'extention duex5 a mon avis comme sa je serai bien pour rajouter le 3 eme moteur pas a pas sur z, et moi rajouter mon extrudeur manquant pour le chario idex, et je serai parer pour l'avenir je pensse

@dc42 If I issue a G28 Z then wont it start to start a cyclic dependency. Since homez has a G32? Or should the G32 only be in home all?

@Phaedrux, thanks! It is difficult to run multiple prints with a single change when the print is 13 hours long but I will keep this in mind and play first with pressure advance and with printing the outside wall first. Retraction settings are a bit of a mystery to me beyond the fact that too much retraction will quickly lead to a clogged nozzle. I am currently running 1.5 mm which may sound low but with a pressure advance of 1.0 ( around 800 mm for the bowden tube) I get extra retraction at the end of a move and I am hesitant to increase that. Retraction speed is at 30 mm/sec.

Well I'll be, I'm officially dumb as a box of rocks - it works - can you explain how the current reduction works ? Is this a reduction in the actual current or the detection - seems a bit counter intuitive - I was reading all the stuff about how too slow and such is a problem. Just trying to understand without code diving.
