Hi, I'm also trying to use DRV8825 driver modules with the GTM32 (rev A) board on my M201. I'm finding that the home function doesn't work through Repetier Host, which means every time there is a problem printing (which happens A LOT still) I have to manually reposition the bed and the print head be...

Been reading on the web about this, and it appears to be an issue with either the duration of the pulse sent to the DRV8825 or the delay between pulses (which I guess is related). That would suggest that the firmware needs to be tweaked to make it work. Moreover, it explains why it might have worked...

Hi, curiously enough I have (literally in the past 24h) started to get the same problem on my Y-axis - it won't home at all... I'm guessing something in the firmware can't handle 1/32 microstepping properly, but since it -was- working for me and now isn't (and nothing changed in the interim, other t...

Mark, Is there an NDA or something in place to allow 3rd party developers access to the GTM32 firmware source code? Just asking, because I'm a C/C++ software developer (20 years experience), and have some skill writing software for set-top boxes, embedded systems, etc... I might be able to implement...

Hi Mark, Here's the list that should really be in there (ones in bold are important - the others are nice-to-have): - M0 - M1 - M92 - M93 - M110 - M301 (this would simplify change of the hotend to use another thermistor, and makes swapping hotend possible) - M360 - M400 So 2 essential M codes, and 6...

HI Mark, Thanks for this list. I have observed unexpected behaviour whilst trying to use OctoPrint/OctoPi with the M201. After speaking with Gina (@foosel) and others, and reviewing the Marlin (v1.0.2-1), Repetier (0.9.28) and Smoothie (edge) firmware source code, it seems as though the behaviour fo...

Hi, I've been discussing the M201 with the team that developed OctoPrint, because I can't get my M201 working with an OctoPi v1.2.9 installation. As pointed out in other posts, the firmware in M201 is still very young and has a number of issues. What would be really helpful is a complete list of wha...

@stado65 I can't get beyond the "Operational" prompt in OctoPi, no matter what I do... If you have a set of configuration values I could have a copy of (and a set of what steps you use to get it to work), it'd be greatly appreciated! Good news, though - I'm printing the last part for my MPCNC tonigh...

@stado65

How did you get OctoPi working with the M201? Every time I try to print, I get the status going from Operational to Cannot print immediately... I've never seen my M201 even start to print unless I am using Repetier Host to drive the printer

@stado65 I think I have fixed the layer shifting completely now - I've done 2 things, so could be either/both: Added an 80mm fan blowing across the GTM32 changed the A4988 on the Y-axis to a DRV8825 Works like a charm now... printed 4 parts @ 4 hours each with no hiccup yesterday, so fingers crossed...
