What is the problem?
The printer behaves differently when Octoprint is being used. When doing curvy areas (possibly with retractions) the extruder starts making a skipping sound, shaking the printer. When the printer is laying down support structure, it seems to move too fast, essentially peeling off the support (on the first layer). This ONLY happens when I use Octoprint, and it happens every time. When using Simplify3D's control panel, or an USB stick, everything prints fine. I've also tried running Octoprint from the laptop that I use the control panel, and experience the exact same problem.
When printing with Octoprint, it seems to ignore speed settings and move too fast (similar to this thread). The result is a clicking noise at the extruder during certain operations (probably filament skipping?). The clicking noise seems to mostly happen at locations with many curves. When printing supports, the nozzle moves too fast, pulling the filament back up. Everything works fine when printing with Simplify3D's control panel or an USB stick.
At first I thought the filament was skipping because the printer was trying to extrude too fast, but this doesn't seem to be the case after looking at the videos. The filament skipping seems to happen at the same speed.
What did you already try to solve it?
I don't have the Exclude Region plugin installed, but tried to uninstalling all other non-essential plugins anyway. Ran octoprint in safe mode (probably redundant?). I've tried printing the same parts from an USB stick and the Simplify3D control panel, which worked fine. Tried changing gcode flavor and lowering the print speed in Slic3r PE.
Edit (Additional things attempted):
- Tested the same printer running Octoprint from a laptop instead (works perfectly fine with the same laptop running the S3D control panel).
- Checked GCODE Scripts. Only the cancel script is there.
- Tried to disable Linear Advance with M900 K0
- Tried a different version of Octoprint (1.3.4,6,8 and 9rc2)
- Installed a fresh new Octopi again
- Different slicer
