BL-Touch and problems



  • Hello Sorry i know i have read a lot of Help messages about the BLTouch. Well here is Mine. I am working on upgrading my cr10s pro and the old board went bad. I got the new DUET Ethernet with the 7" screen .. seem to take me no time getting thee system running and all back on line. At the same time i get the new board and had them send me BLTouch . Well there is where the problems start, as you can see i just got the new system and i might be missing something .. i have tried a lot of the forum reading and still can't get the #$%^&* working

    Board: Duet 2 Ethernet (2Ethernet)
    Firmware:
    RepRapFirmware for Duet 2 WiFi/Ethernet 3.1.1(2020-05-19b2)
    Duet 2 Ethermet v1.04c

    I think i am using PIN#31 on the Expansion plug
    I have checked the wires and plugs with a multimeter. I know the connections are good i used my own wire so the colors are off. And again i checked like them 20 time Over and Over.
    I tried
    HEATER 3 pin8
    HEATER 4 pin13
    HEATER 7 pin 31

    Before you ask i used blank plugs as place holders so that i could not put it on the wrong pin, never changed anything with power on! I am thinking that The BLTouch is BAD???

    401 and 402 do nothing ... when i turn the printer it cyclus 2 time probe go out a back in .. Stays read looks like it ready to go .. but nothing happens.. (Might also say i have never had a BLTouch so i am not sure what it should DO)

    I will include my retractprobe.g & deployprobe.g & Reset BLTouch & Test BLTouch

    I know someone will look at this and say i know what you did wrong ... beats me .. I love the lay out i gotten good at the program and love being able to edit files from the SYSTEM DIR...Very Very Cool. now if I can just get the BLtouch thing working 😲

    I am going to Upload my Config.zip if that might help:

    Thanks for a great Board and Software

    @n3ovo said in BL-Touch and problems:

    You mean M401 and M402 I presume?

    M307 H7 A-1 C-1 D-1 ; Disable the 7th Heater to free up PWM channel 5 on the Duex board.

    Remove that line from config.g. It's needed for RRF2 but not for RRF3.

    M280 P7 S10 I1 ; deploy BLTouch

    Remove the I1 parameter and use P0 not P7. Likewise in retractprobe.g. Again, this is because you are using RRF3 not RRF2.

  • @n3ovo said in BL-Touch and problems:

    M280 P7 S10 I1

    try a

    M280 P0 S10 I1
    

    because you mapped the PWM Channel with the M950 Command to GPIO 0

    for example (taken from the wiki)

    M950 S0 C"exp.heater3"  ; assign GPIO port 0 to heater3 on expansion connector, servo mode
    ...
    M280 P0 S80  ; set 80deg servo position on GPIO port 0

    @n3ovo said in BL-Touch and problems:

    Does the BLTouch do a self test at power on? This checks that it's getting power. Probably not, because...

    M950 S0 C"exp.heater7"

    Servo "0" has pin defined on heater 7, so should be on pin 31. This is the tenth pin from the top in your picture. A little hard to tell, but it looks like you're on the ninth pin. Move it down one. See https://d17kynu4zpq5hy.cloudfront.net/igi/duet3d/vqBUAZPsxMC5tRgt.huge

    As @dc42 says, deployprobe.g and retractprobe.g are set up for RRF2, as are your test BLTouch macros. Use M280 P0 rather than P7, and no 'I1'. For more info, see https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_Software_setup_RepRapFirmware_Num_3 for correct format.

  • If it helps - I was setting up a BLT a week or so ago and (with help from this forum) ... here is the relevant section from my config.g

    ; Endstops
    M574 X1 S1 P"xstop"                           ; configure active-high endstop for low end on X via pin xstop
    M574 Y1 S1 P"ystop"                           ; configure active-high endstop for low end on Y via pin ystop
    M574 Z1 S2                                    ; configure Z-probe endstop for low end on Z
    
    ; Z-Probe
    M950 S0 C"exp.heater3"                        ; create servo pin 0 for BLTouch
    M558 P9 C"^zprobe.in" H5 F120 T6000           ; set Z probe type to bltouch and the dive height + speeds
    G31 P500 X42 Y5 Z2.21                         ; set Z probe trigger value, offset and trigger height
    M557 X45:220 Y10:220 S20                      ; define mesh grid
    

    In my case - exp.heater3 is pin8 (fourth pin from "bottom left").
    In your case - exp.heater3 is pin31 (as stated - 10th pin from "top left").



  • Edit to above post
    In your case - exp.heater3 is pin31 (as stated - 10th pin from "top left").
    In your case - exp.heater3 is pin31 (as stated - 10th pin from "top right").



  • Hello Again ... I would like to THANK all who helped. I now have a working BL-Touch ... My wife and I Me where shocked, How fast you all answered me with help .. I does pay to get in a great group of people. It was on the wrong pin and I was was using the wrong commands for the wrong port .. so I am a happy camper..(I'm A HAPPY man) 😎

    But as always one steep forward 2 steps in #$%^... i got it probing and it is doing good but i can not get it to start probing from the center of the bed for z-homing ( homeall or homez) Keeps wanting to home and the X-0 and Y-0 witch puts if off the bed and that will not work. I come to the wizards once again with G-Code In Hand

    Ps if you would look over the CODE real quick and see if i made any more boo boos. thanks

    As Always Thanks again

  • @n3ovo said in BL-Touch and problems:

    G31 P25 X25 Y5 Z3.15

    If the offset is set correct, you have to calculate the center by subtracting the values from the center.
    As an example
    When you bed is 335x335 (375-40, set by the limits in config.g)

    335/2-25= 142.5

    Change that line
    G1 X-150 Y-150 F6000
    to
    G1 X 142 Y 142 F6000

    Edit: In homeall.g and in homez.g



  • oK THANKS Just fixed both all and z .. tried to do a mesh and i get error g29 "zprobe was not triggered during probing move"
    this is because it homed to X and Y no problem but did not move back to the table before going down for first??

    What did i do Now 😧

    Ho and thanks ...



  • @n3ovo
    I'm not shure if I got you...
    But the machine has to be homed completely before executing a G29
    So run a G28 first



  • One thing I would suggest is to set your Axis Limits like this

    M208 X0 Y0 Z0 S1                            ; set axis minima
    M208 X375 Y375 Z400 S0                ; set axis maxima
    

    I suspect your current settings are confounding the situation.

    Then take a look at your z-probe offset as measured in your G31 command. The distance from the nozzle to the probe in your case is 25mm in the X axis. The cr10s-pro looks to be (more-or-less) the same setup as on my Ender 5. Probe to the left of the nozzle when viewed from the front. It could be the mount but for reference - I have a 42 mm offset.

    You can then play with the M557 command to keep the probing inside the bed. Lastly you may try this form of M557 - it probes in a grid pattern starting at the min X and Y positions with a distance specified by the S parameter (in mm). In this way there is no need (or advantage) to start probing from the middle of the bed. You could start with S40 to make it quicker (also helps with initial leveling using the bed leveling screws).

    M557 X45:220 Y10:220 S20
    

    Remember to add something like this in your slicer pre-print code. Note that the G29 S1 makes sure that the results of the last bed-leveling (G29) are recalled. Personally - I do not do a G29 for each print - maybe once a week or if I am going to print something in fine detail.

    M117 Homing
    G28 ; home all without mesh bed level
    G30 ; Do a single probe just to be sure
    ;Optional Bed leveling - enable G29 when needed
    M117 Leveling Bed
    ;G29   ; uncomment to re-probe the bed
    
    G29 S1 ; enable mesh
    


  • Hello Again ... back with more questions and as alway the last answers help all of my past problems 😲

    1. how big can the sd-card 64 ? 128?
    2. I would like to add a camera to the system. is there just a wifi/wired small camera i can use for monitoring the printer at will get me a JPEG picture like it's neededs ( thought I see something before but forgot you look closer now i just forgot.

    Now on to my next problem ... i have been working on my printer bed all this time as soon as i got the Bed Mash Compensation working ( and man was my bed messed up )
    i got it all working but when i go to print it will not move down to the set height of printing nozzle. Stays at the bl-touch hight. ??? tried and tried. Worked all night on it and just can't get is to working . I know that it is something i have (Again) mist!

    I am Sending my code but i don't think this will show anything. Also sending what i have tried to follow

    • list itemCalibrate the Z probe trigger height

      Make sure the dynamic test is successful (Z probe stops when it senses the bed) before doing this.
      Cancel any currently active mesh compensation with M561
      Use the X and Y jog buttons to position the nozzle over the centre of the bed
      Jog the nozzle down until it is just touching the bed or just gripping a sheet of paper. If the firmware doesn't let you jog it down far enough, send M564 S0 to disable axis limits.
      Once you have the nozzle touching the bed, send command G92 Z0 to tell the firmware that the head is at Z=0
      Jog the head up by 5 to 10mm

    Send command G30 S-1. The nozzle will descend or the bed rise until the probe triggers and the Z height at which the probe stopped will be reported. If you are using a nozzle-contact Z probe, the trigger height will be slightly negative. For any other type of Z probe where the probe triggers before the nozzle contacts the bed, it will be positive.
    Repeat from step 5 two or three times to make sure that the trigger height is consistent.
    In Duet Web Control, go to Settings -> System Editor and edit the config.g file. Set the Z parameter in the G31 command to the trigger height that was reported. Save the file.
    Open config-override.g and check that there are no G31 commands in it. If you find any, delete those lines and save the file.
    To apply the new trigger height, restart the Duet by sending M999 or pressing Emergency Stop.



  • Your trigger height should be a positive value, not a negative value.
    Change

    G31 P45 X25 Y5 Z-2.90  
    

    to

    G31 P45 X25 Y5 Z2.90

    Remove the M307 line entirely. It's not used in RRF3.

    And remove the X200 Y220 Z1 from your M558 line, those values are not used there at all.

    M208 X50 Y-25 Z0 S ; set axis minima

    Does your X axis endstop really trigger when the nozzle is 50mm inside the printable area?

    You're S parameter is missing the 1 there as well.



  • @n3ovo -- The gcode that I posted a few days ago should pretty much "just work" for you. Given the similarity between your Ender and mine.... Z offset will be different and you are using a different pin but other than that .....

    I'm still suspicious of your X axis offset. Can you include a picture taken from the front that shows the nozzle and the probe? It's hard for me to see that 25mm is correct given how most BLTs mount relative the the stock ender hotend. Having said that, anything is possible - but worth double
    checking.



  • Thanks All, I Did my FIRST Print ( I will show Pictures Below ) All your help was just Wonderful to a newcomer. Don't be worried I will have more question .. hope that i can pass on to someone my help like you all did for me.

    I think I have fixed all errors in my config.g ( don't yell if i missed some there were a lot! 😲

    I know i can do better.but no to bad for the first print.
    sending my config.g just to see if i got it all worked out

  • Congratulations on your first print - doesn't it feel great when that happens !!

    A couple of observations.

    I think your line for the axis minima may have an error (space between S and 1). I'm not sure if its an error but its not clear if to me how the interpreter will see it. i.e. I believe it needs to be

    M208 X0 Y0 Z0 S1                              ; set axis minima
    

    Also - Its not clear that you have the correct form for your M557 line. The documentation is a little vague - but it does suggest the form you have is deprecated. Does your bed leveling actually happen ? The new form is to just define the bed limits and the probe interval.

    https://duet3d.dozuki.com/Wiki/Gcode#Section_M557_Set_Z_probe_point_or_define_probing_grid

    Good luck moving forward 🙂

    The M557 command he has in there is perfectly fine.

    I know i can do better.but no to bad for the first print.

    It looks pretty good for a first print!

    Now that you have everything functional it's time to do some calibration. Mainly the extruder and all that entails. This guide might help you along.

    https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+4:+Calibration/40

    Then you may want to look into tuning pressure advance once the extruder is calibrated.

    https://duet3d.dozuki.com/Wiki/Pressure_advance

    After that it's all a matter of learning the slicer settings.



  • Just When you though it was SAFE ... More Problems... Printer is working .. Started tuning the printer and i seem to have a problem. It is only printing on one side of the bed. I tried to print a case for the i7 screen .. I know i am jumping the gun. I wanted to protect the Screen.

    Anyway here is a Picture Only the Right Half:

    picture.jpg

    As you can see it prints right up to the X limit Switch hits and the closes of the BOX .....

    Any thoughts Would help .. I know it is something that i have done Just don't know

  • Test manually

    i assume from your config that the bed is 300x300

    issue G0 X0 Y0

    see that the head moves to one edge of the bed

    then issue G0 X300 Y300 and see if its moves to the opposite side of the bed

    Remove those lines from your cura start gcode. Also make sure that you have reprap gcode flavor selected.

    It seems like your axis minima maxima is not quite right.

    0,0 should be the front left corner of the bed. If the nozzle can go further to the left or front than that, the minima would then be negative.

  • Just checked accordance on the printer If I type 0 0 it's up in the front left hand corner If I type 300 300 it's in the back right hand corner It goes to the center at 15150 I can hit any part of the bed and with a tape measure as close as I can possibly get it's right on the money So why is the program Why when I print does it go crooked It looks like when I print it it only thinks it has half a bed but only half on x why seems okay



  • "Origin at center" in cura(or some other slicer You are using) machine settings perhaps ?

    Or....

    G10 P0 X45 Y0 Z0

    Why Do You have tool offset 45mm for X axis ??
