Repetier for K8200

cosudorcosudor
in Motherboard
Dear all,

I've more or less easily managed to run Repetier Firmware on my RADDS board, and as I am very satisfied with Repetier, I now desire to run it on my stock K8200 motherboard as well (it has been switched from my K8200 to a homebrew router, but it looks like Repetier might be well-suited for this task, too).

I assume it would be feasible to tweek some repetier pin configuration "manually", or modify/add some entries in boards.h (or similar).

But then again maybe:
  • somebody did this already!? (I searched this forum and saw some people use K8200 with Repetier, but no details)
  • it is preferable to introduce K8200 support "on a higher level" (maybe including web configurator).

So I ask myself about the best approach. Even if my C/C++ programming experience dates back 30 years and the last 15 years I did mostly Java, I could probably help and contribute, though some basic guidance would be welcome.

Kind regards,

Michael

    Hmmm. I tried to use "userpins.h".

    Got very strange error:

    In file included from Repetier.h:457:0,
                     from Commands.cpp:22:
    HAL.h:34:20: fatal error: avr/io.h: No such file or directory
     #include <avr/io.h>

    compilation terminated.


  • cosudorcosudor
    My fault. Seems my ide was still set to the Due because of RADDS board.
  • cosudorcosudor
    I now have a working "userpins.h" for a 3DRAG/K8200 printers motherboard. At least all pins used for CNC milling have been tested. Thermistor pins are defined, but untested.

    Lets see where I can contribute is. Perhaps it would be feasible to weave it in the original pins.h, so Repetier firmware supports K8200 "out of the box"?. Velleman already uses Repetierhost, but only with Marlin.

    And for "out of the box" you'd have to consider the different modes of enable/direction with regard to the stepper drivers.
    I replaced mine with the Watterodt SilentStepStick (direction pin inverted).

    Regards,
    Michael

    For inclusion in original firmware I need a full setup meaning all stepper/heater/thermistor pins set correctly. Then I could assign it to pins.h. Is 3DRAG the motherboard name?
  • cosudorcosudor
    I have a more or less complete list of pins obtained from some other post. But as I currently use the board in a cnc router, I could not verify all pins. But the risk should be minimal. The primary confusion is about heaters. The userpins.h mentiones heaters by number (0, 1, ...). I used "0" for the printed bed heater and "1" for the extruder heater.

    (slightly off-topic: when playing with M3, M4 and M5 with the router I observed strange behaviour; after some analysis it seems a statement like "direction = 0;" is missing in CNCDriver::spindleOff(). At least this fixed it for me.)

    "3DRAG" is the name of a (Italian?) 3D printer. The same printer was sold by (Belgian?) Velleman later as "K8200" and became quite popular in Germany. The firmware shipped with it is Marlin, but they recommend RepetierHost as Frontend.

    The motherboard does not have a special name; I heard it is a modified Sanguino something.

    Should I simply post the pin assignments here?



  • RepetierRepetier
    Yes, please do. I could add it with flag untested. Would at leat help. Not sure with heaters as we use heater 1 for bed traditionally. If that is how it came wired I should switch pins for 0 and 1 to keep repetier numbering.

    If it is sanguino did you uload/compile with sanguino board selected? If you used mega2560 to compile it is is not sanguino.

    I used this as "userpins.h" and set motherboard to 999. Worked for me.
  • cosudorcosudor
    BTW: could you verify my problem with missing "direction = 0;" in  CNCDriver::spindleOff() which I described above?
  • cosudorcosudor
    Hmmm. Just noticed the 0.92.7 which has the spindle issue fixed. Thank you.
  • RepetierRepetier
    I'm a bit unsure about this

    that makes no sense since it will not trigger if you have sanguino or Mega selected, but it can only be one of both I think. So what board do you use to compile? With that info I know which one is the needed one.

    Here is a board description from K8200 Wiki.

    3DRAG and K8200 both use the same ATmega2560-based design.
    The wiki article explains that it is a successor of Sanguinololu Controller (ATmega644 based).

    I have 'Arduino Mega' selected when compiling.
    I assume the pins _will_ fit the 3DRAG as well.

    I fear the pins will _not_ fit the older Sanguinololu.

    Does this sound reasonable?

  • RepetierRepetier
    3drag states it self you can use native arduino ide with mega as is not a real snaguino any more. Just maybe designed from the same people, so the mega condition is the right. I have now included the pins as board 66.
  • cosudorcosudor
    I can confirm that the stock 0.92.7 works for me using board number 66. Thank you very much.

    I can confirm that 0.92.8 works with board 66.

    Seems to work better then Marlin so far in the sense that the temperature curves in Repetier Host now work all the time. In Marlin they block during M190 G-code. Also I have the feeling it's smoother. Marlin has little mechanical glitches during communication.

    Hi all,
    i'm trying to set Repetier Firmware for my 3Drag.
    Anyone can tell me witch DISPLAY_CONTROLLER i have to set for the one that comes with the printer: https://www.futurashop.it/stampanti-3d/elettronica-2/scheda-lcd-controllo-autonomo-3drag-montata-8220-vm8201 ?
    Thanks

    I would also like to get repetier firmware to work with vm8201 display. I'm stuck using Marlin firmware if I want to use my display.
