I never got my chameleon mk3 to work in the past.
In the end I gave up as it took me too much time to get it working and I started to hate it (sorry Bill).
Now almost a year later I see the mk4 files are available so I printed them in the hope they will fix all the problems I had with the mk3.
I notice there is no spacer included in the files.
Is the spacer between the stepper-motor of the extruder and the body of the chameleon no longer needed for the mk4?
The only files included are the upgraded files, all the rest are the same.
The spacer is just a generic NEMA 17 2mm spacer from Thingiverse.
