I believe I’m getting skipped steps on my Y-axis. My prints come out with area’s shifted 1-2mm to one direction on the y axis. Consistent all the way up with spacing anywhere from 5-15mm between shifts. The shifted print area only last for about 5-10 layers and then it shifts back. I will upload pictures tonight. I think the problem might be my servo’s overheating? I’m running the medium abs auto support slic3r settings from lulzbots site with a few adjustments that would not affect this like a wider brim .
Here’s my analysis so far.
-first noticed on large prints with large infill area’s (1hr plus times and sizes larger than 60mm area’s)
-small objects less than 40mm by 40mm and print times of under 40 minutes or so are fine
What I’ve done to mitigate the problem at the moment
-slowed any speeds in slicer to be no faster than 105. The only 2 speeds that were faster are nonprint moves(150) and nonsolid layer infill(115).
Slowing the speeds has completely stopped this from happening but has added a lot of extra time to my prints. I’m pretty sure the infill speed of 115 was fine but the movement speed of 150 was the problem. I haven’t tried to isolate it any further yet but I just wonder if anyone else has had this problem. Like I said tonight Ill put up pictures of the prints and also hit the servos with my IR thermometer. Is my thinking right or is it something else?
