I had to replace the B and C parts in the Chameleon as the tubes fell out of the grips that used the brass compression fittings. I cut the PTFE tubes and they seem to grip well in this. But, it seems tool 1 and 2 pull with less force than 3 and 4 now. Because of this, I printed the +2.0 tension adjusters and put those in. Tool 1 and 2 still pull with less force and have trouble rotating a full spool of filament on a mount (tool 3 and 4 do this fine). Visually, it seems the drive gear is pushed further into the bearings on the tool 3 and 4 side than the tool 1 and 2 side. Any ideas on what I can do to solve this? Thanks.
