Can't figure out what's causing my XY skipped steps
-
CoreXY - My motors run cool, even at 1400mA. Is it possible they just get overpowered by inertia? I'm never there when it happens.
How can I diagnose it? There aren't messages when it happens. The only time I get messages are if I run current that's too high, and even then they still run cool to the touch.
-
Which Duet, which firmware, and what is the motor specification?
-
Maestro 2.0.2-r6

12v or 24v?
have you configured them in stealthchop or spreadcycle?
what speed are you printing at?
first thing to try is lowering your acceleration and max speed.
-
24v
It's happening even on slow prints. I finally witnessed it. I just heard a quick CLUNK. The motors are still barely above room temp. I'll try lower acceleration.

@gnydick Update to firmware 2.02, there was a bug fixed after RC7 which could explain this.

@iratecrayons fingers crossed
-
@gnydick
on slow prints do you also decrease the travel speed? because normally those are separate. -
@veti Yeah, it's all proportional
-
can you try putting all drivers into spreadcycle?
using M569 P[0 till 4] D2
