  • I think I may try Klipper to side step the step rate limits.

  • I'll look into it. I use the PICA board instead of ramps which works great but I'm not sure if I can make it work with a 3.3v Due controller. Might be stuck for a while. Thanks for all your help figuring this out. I get great prints right now a…

  • I'll give 8 microsteps a try. I do quite like the quiet operation of 32 though.  Would upgrading to an Adruino Due solve the frequency limit automatically? It may be time to leave 8 bit behind.

  • Arduino ATMEGA. PICA shield. Extruder stepper is 0.9 degrees, on a Titan V6, DRV8825 with 32 microsteps. This leads to a fairly high e steps per mm of 1800. Could that be saturating the E interrupt?

  • I used M232 and reran the file and it printed properly this time. The extruder did not reverse even up to M233 Y50. I'm going to test a print now with M233 Y30 which looked to have the best line quality. Test print failed. The lines were very thin…

  • Automatic retract is disabled. I wasn't aware of the M232 command before. I should add it to the test file. While looking up the M232 command I found this: https://github.com/repetier/Repetier-Firmware/wiki/Hardware-settings-and-print-quality I'll…

  • What could be causing the behaviour I'm seeing?

  • Yes I've been using the Dev 1.0 built fresh from here: https://www.repetier.com/firmware/dev/ Acceleration is 800, which I thought was pretty reasonable. My entire configuration.h file can be seen here: https://www.dropbox.com/s/7o7qa56wfor2cj0/Co…

  • I've been completely unable to make it work as expected. The extruder always reverses at some point no matter the value selected with M233 Y0 to M233 Y50. Even with a M233 Y1 value the extruder will reverse after a few seconds and eventually will re…

  • I'll have to do some more testing. Thanks for the info. If I can get it working well maybe I'll write up a tutorial to make it more accessible.

  • I just discovered the M233 gcode, which doesn't appear in the gcode wiki. The feature is obviously obscure. No matter what value I use, the extruder begins to reverse itself shortly after the start of the print.
