Extruder motor not working.

gloomyandy

@jfavre Are you sure you have a tool selected (with T0, you will need that as well as the M302 P1)? What response did you get to M302 (before and after you set M302 P1)? Have you tried heating the nozzle?

jay_s_uk

@jfavre the tool isn't active so it can't be used to extrude and that's clear from your screenshot. Send T0 to active the tool

Now i am getting the following error.

12/27/2022, 4:46:01 PM G28 X
Error: Failed to enable endstops

Can you send M98 P"config.g" in the gcode console tab and copy and paste the results?

Also post your homing files.

For the extruder, try setting an actual temp.

Alternatively if you just want to test the motor itself, you can send M584 X0.3 in the gcode console and then send G92 X10 and G1 X1. That should temporarily bind the extruder motor as the X axis and attempt to move it a small amount.

Sending T0 initiates the heater and then faults out.
Heater 1 fault: temperature rising too slowly: expected 2.36°C/sec measured -0.00°C/sec

The homing was working just prior to this.
I did test motor by plugging it into the x axis channel "driver 0"

When I try to heat filament I get the following error.
Heater 1 fault: temperature rising too slowly: expected 2.36°C/sec measured -0.00°C/sec

This board is over a year old and has been sitting on the shelf. I have not set any PID values nor have I looked into the heating situation. Thermistors seem to be working. Sometimes looses communication then reconnects. Not sure what else to add. Any help would be appreciated.

When you try to heat does the LED near the heater terminal actually turn on? Can you see any rise in temp on the graph before it faults? Have you double checked the wiring for the heater cartridge? Check the resistance of the heater with a multimeter?

@jfavre said in Extruder motor not working.:

And does it work there?

jfavre

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

Phaedrux

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.

G1 E1 F100

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?

@jfavre said in Extruder motor not working.:

till no luck with Extrusion Control jogging buttons.

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

@jfavre said in Extruder motor not working.:

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

jfavre

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

jfavre

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

jfavre

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

@OwenD awesome! Thanks, l will try tomorrow.
