Testing firmware 2.12 ...
16 hours elapsed so far with over 1700 tool changes only... that's because I'm currently testing stall handling on the Feeder (TMC2209), which requires the feed speed and acceleration to be reduced drastically to about 20 mm/s for feed, 3mm/s for acceleration.

The second endstop down on the Selector bowden tube is just for testing and used to check whether or not the feed made the whole distance (recommended, if you're running the test over night and want to get some sleep as well).

So far, 22 stalls have been detected of which 21 have recovered automatically.

You may have noticed, the Servo-Shoe has been replaced by a bearing. Helps a lot against wear.

Is the slack in the furthest rod intended as to take up torqe forces from the servo?
