I’m not sure what to search for. I’m sure it’s user error on my part somehow. Sometimes during a “print” with my router in the MPCNC, it seems to get “confused” for lack of a better word. Sometimes after its little detour it gets back on track, sometimes it doesn’t. The detour typically destroys the workpiece. In this latest occurrence, the router lifted up to shift positions without cutting, but lifted higher than it should have; when it arrived at new xy, it went down the correct amount, leaving the bit floating over the workpiece as it continued working. A brief glance at the g-code file indicates that all the delta-Z values are identical, which I believe rules out Estlcam as the culprit, leaving repetier-server and the firmware, or a hardware issue. Not all “prints” are affected.
Repetier-Host 0.75.1 running on Raspbian
Whatever firmware the RAMPS board shipped to me with
All of the plastic pieces were produced at my local makerspace, but all the motors, electronics, wiring etc were purchased from v1engineering.com. Tool mount is from thingiverse, everything else printed from your files as of a few months ago (includes better middle Z, but does not include “major update” parts with new motor mounts etc). No end stops.
Photos, images, estlcam and gcode files available at http://yumesoftware.com/bunny_failure.zip. At 27mb it’s too large to attach to this post.
I’m happy to provide additional information if you can tell me how to get at it. Any and all help much appreciated. Thanks a bunch!
