I have a GeeeTech A10T printer. This printer has three extruders but one hotend.
I have two other printers, and control all three with Raspberry PI’s running Octoprint, and have successfully printed multicolor prints on jobs sliced in Simplify3d and sent to the Octoprint instant controlling the A10T.
Recently Octoprint started getting “Invalid Tool” errors and can no longer successfully print on the A10T.
OctoPrint is updated to the latest version. The printer is running Marlin 1.1.8. I use Simplify3d, latest version as a slicer.
Prior to this is successfully used GeeeTech’s color mixer to do multicolor prints from Simplify3d generated gcode via Octoprint on the A10T
Now OctoPrint will not print multicolor prints, throwing multiple invalid tool errors. The job prints, but it prints in a single color using whichever tool I selected as the first tool to print.
The job will print successfully in multicolor if I print directly from Simplify3D via a USB cable.
I can generate gcode files in multiple colors with Repitier-Host and successfully print them via Octoprint.
I’m hoping one of you smart people out there can help a dummy figure out what is going on. I’ve searched the forum and found things mentioning virtual extruders, but I haven’t got a clue how I would configure those.
The logs and screenshots are attached.
What did you already try to solve it?
Searched the forum and web.
Have you tried running in safe mode?
No, safe mode doesn't support multiple extruders
Did running in safe mode solve the problem?
