Does someone also ran into this problem?:
I wanted to print a dual color object with my i3 MK2MM via OctoPrint (1.3.9rc1) today.
The pre-purging worked fine but already the purge block was a mess.
Printing from SD card the same gcode was no problem.
So I did this:
Downgraded OctoPrint form 1.3.9rc1 to 1.3.8 -> no change.
Downgraded Slic3r PE from 1.40.1 successive to 1.38.2 -> also no success.
Now: Printing a delivered model (Marvin, Slic3r PE 184.108.40.206) works fine with OctoPrint
Single filament printing is no problem too.
The OctoPi version is 0.14.0. There are no error messages from OctoPrint.
First I assumed it was the "Display Layer Number" plugin because it slightly changes the gcode. But this one is not guilty.
Anyone any idea?
