Hello! I have installed my new Chameleon and have had a few problems. I had some loading issues with the filament getting caught on the extruder tension arm, caused I believe by the printed coupler being a couple of mm too high as the tube through the coupler does not line up with my metal extruder tension arm, it's just a bit too high. So I am attempting to re-print that after having modified it a bit. But here's where I started running into trouble.
I decided to load filament through Chameleon 1, then switched it to Chameleon 2 manually, so that it is not gripping the filament and feeds directly into the Ender extruder, basically as though the Chameleon was not installed at all. The printing began just fine, and it ran through the button presses (I unplugged the Chameleon so it didn't react) and held the tension arm so that it didn't try to feed a ton of filament through rapidly. Once it was done with that cycle it moved to the center and began its normal printing cycle and I immediately noticed an issue.
The print head will do curves quite slowly and, during these curves that it's traveling too slowly, the Ender extruder is turning extremely fast causing blobs and the filament to be ground down by the extruder gear. Faster than any other time that it would normally be turning. Then when it does straights the extruder will turn very slowly, the normal speed I would expect it to be turning, but the print head moves way too fast. I spent quite some time isolating the problem and ultimately what I found is this; if I remove the tool change G-code start and end g-code all of these problems go away and prints work exactly as they should.
I am using the G-Code generator and after having watched your video on the g-code part with cura a couple of times, I can't figure out what is causing this. I would greatly appreciate any help or advice on this. I am using the most up to date Cura version as of this writing; Apr-17-2022
