With the fighting season winding down, printing season starts up. Last, I was stuck at the extruder motor being unwilling to move, even at proper temperature. +Tim Hatch gave some ideas for fixing that in the last post:
Check motor current - checked black wire first, it shows about 10-20 mA whether running or not. Green and blue show nothing.
Can the extruder move without any filament - heated up and pulled out filament all the way. Still doesn't move.
Compare with a spare motor - don't have any here.
Swap drivers with X - tried swapping pins in pins.h, but that didn't take, oddly.
Noticably, the motor gave a brief "clank" when first set to move. That could be problems inside the motor, or maybe that one of the connections is faulty, so the motor moves a quarter rotation, then stops. This is repeatable after the power has been off.
Enough for tonight (got out here rather late and poorly prepared). Next time, bring extra motor and extra clippy cables - everything has moved here in FabLab. They also got a huge laser cutter, that'll be fun once it's up and running!
