Extruder motor not working
-
I tested it for polarity and wired it the same way as the three axis motors. They move the extruder doesn't. Its a Bowden on a Delta using RepRap firmware. There is no hot end yet and no heater. THe motor is geared 5:1. I am just trying to calibrate the motor. I am probably missing something simple but I can't seem to find my problem. Any suggests as to where to look next? Should I connect it to X and see if it turns?

When I try to extrude I get a Red circle with a line through it!

If you have no hotend configured you probably aren't reaching the safe extrusion temperature.
During testing you can use M302 to allow cold extrusion.

@phaedrux Thanks, I will try that, but my hotend thermistor is absent and the control shows 2000 degrees.
-
In order to extrude:
-
The extruder drive concerned must be assigned to a tool. This is done in a M563 command in config.g.
-
That tool must be selected. Use a T command to select it, for example T0 to select tool 0.
-
If the tool definition includes any heaters, either those heaters must be at 160C or more, or you must have enabled cold extrusion using M302.

@phaedrux Thanks, it was a combination of no thermister and allowing cold extrusion. I had to connect a thermister and the do M302P1 and I was able to configure my extruder. Thanks for the quick help!
