Supported Stepper driver ICs

[mamama1]

Hi

where do I get information on what stepper driver ICs are supported/tested by the current Marlin AVR 8 Bit branch or which requirements they have to meet to work?

Thanks

What drivers are you targeting? Provide the list you're interested in, and we should be able to tell you if that chipset is supported.

I know TMC2130, TMC2100, DRV8825, A4988 are supported.

Also depends on your control board. Example the TMC2130 is not yet supported on the Re-Arm (LPC) chipset yet...

Provide details on your setup and I'm sure you'll get a more useful response.

from code:

  // Init TMC Steppers
  #if ENABLED(HAVE_TMCDRIVER)
    tmc_init();
  #endif

  // Init TMC2130 Steppers
  #if ENABLED(HAVE_TMC2130)
    tmc2130_init();
  #endif

  // Init L6470 Steppers
  #if ENABLED(HAVE_L6470DRIVER)
    L6470_init();
  #endif

I guess it's not listed anywhere but the ones that require configuration are listed in configuration_adv.h. I think currently it's L6470, TMC26X, TMC2130. Then on the way are TMC2208, TMC2224, TMC5130 and TMC2660. In addition you could drive anything that uses STEP/DIR pulses (TMC2100, DRV8825, A4988, etc).

Thanks! I do not have any preference at all, at the moment. i wanted to choose the "best" drivers for home budget 3D printers like Anet A8, CR-10, Tevo Tornado, and so on. But I wanted to choose better steppers than the ones which are usually delivered with those printers.

They are intended for 8 Bit AVR so too much microsteps wouldn't make any sense if I recall correctly, because the 8 Bit AVRs don't have enough power to utilize them anyway, correct?

[mamama1]

asking the other way round... which features does marlin for the 8 bit AVR platform currently support, which make sense to make use of and which steppers would be good to choose therefore?

I know I may be slightly biased but I'd say the TMC2130. With them you'll get

• Current adjustment through software. So no more fiddling with the current pots
• Ultra quiet motion with stealthChop
• Stepping interpolation to 256
• and if you need more speed than what is suitable for that mode, you can use the hybrid mode
• Sensorless homing for X and Y. No need for limit switches.
• Z axis calibration similar to how Prusa Research printers do it
• Advanced debugging capabilities

Some of this stuff is not yet pushed to upstream but all of it I've already implemented.

i like very much :-) thanks!

I suggest you get originals from http://www.watterott.com/en/SilentStepStick-TMC2130

[mamama1]

sure, digikey has them too...
