So I just got an A10M today. I'm trying to do a build with your configuration.h file for the touch version, and Arduino first is triggering an Unknown Motherboard error. I swapped that to be BOARD_GT2560_REV_A and after that I received a LEVEL_BED_CORNERS requires a LEVEL_CORNERS_INSET value. Pleas...

Saving the gcode to memory card and printing from it is usually the most reliable and safest way to go, as printing isn't affected by usb or computer's stability...

This is a pre-built firmware that can be flashed into printer. There's nothing to integrate. It's offered by me as is and meant for people who don't want to mess around with building the firmware.. As of now I've had 2 successful prints with it. To be honest I've never gotten such level first layers...

So it's the heated bed issue then? Well... Still the same testing procedure applies. If thermistor signal doesn't measure 100kOhm at room temperature, trace the signals and try to find where it disconnects.

thanks, you mean diamond head by "mixing hotend without MMU"

Yep

Could you at least clarify which temperature are you referring to? The heated bed or hotend? And what do you mean by strange temperatures? Can you elaborate? You only explained the temperature with disconnected sensor. Was there a difference in temperatures between disconnected and connected sensor?...

Try to clean the nozzle. Also try above usual hotend temperature. The temp sensor might also be the issue, meaning it's telling printer that the temp is higher than it actually is. Lower temp means that filament can't extrude at normal speeds.

Did you heat it up after assembly and then perform the final tightening of hotend components while it's hot? If not, give it a try.

As of now you can't use MMU and mixing extruder together. That would require pretty big firmware hack. Also no slicing software support this configuration.

Either use MMU with single filament hotend, or mixing hotend without MMU
