Extruder motor not working.

@Phaedrux my apologies, yes the extruder motor did work in the x axis. I will check the led. There was no change in temperature.

Ok if the motor is confirmed working, then at least cold extrusion should allow it to extruder as long as the tool is actually selected.

So please send T0 and M302 P1 and then see if you can send G1 E1 F100 to make the extruder motor move slightly.

The heater issue appears to be separate.

Tried as suggested and received the following error. I have checked phasing by shorting the coils at the connector that attaches to the board and seem fine.

Just got the extruder motor to work with G1 E1 F100 andG1 E-1 F100. Still no luck with Extrusion Control jogging buttons.

Phaedrux

So are you still getting phase errors, or is that resolved?

Send T0 in the gcode console and check the buttons again.

Is the heater up to temperature? By default cold extrusion is disabled and the extrusion buttons in DWC are deactivated.

@dc42 found connection issues with ribbon cable and pcb, new one on order. Then we move forward.

@Phaedrux the phase issue is resolved. Found other connection issues. New pcb on order.

After replacing PCB managed to get everything up and running. Just need to find settings for Slice Engineering 300c thermistor, the temp reading slightly higher than actual measured with an TC thermometer. It was type 5 in marlin.

According to this document, you need to use the following in your M308

T100000 B4680 C6.455513e-8
