RE: Extruder stops mid-print
sorry, forgot to actually attached the STEP file. But it is now included in my printable remix upload. Here
Here's the STEP file for the base. I do have a skeletonized version getting printed and will be up on Printables shortly if you'd rather wait for that.
FYI, The step Files have not been modified, they are the older style. Make sure to print the stl files

Well I tagged it and will be printing it tonight!

RE: Extruder stops mid-print
Best of luck to all XL owners affected by this. Hope we can all put this to rest and get back to actual design work and some real printing.
BTW, I'm still running 6.2.0 RC1. It does not reduce this extruder stopping mid-print issue, but I do like the function where it detects which tool's extruder step motor had stopped responding. IF ONLY, prusa would further enhance this function allowing user to load filament to another tool head if not in use and continue the print. what are your thoughts on that function? I'm just thinking aloud here 🙂
RE: Extruder stops mid-print
I think that's a great idea. Anything that salvages a pending print loss makes for a more robust system.

You can chain two (or more) tools so that one picks up when the other runs out of filament. I don't know if this "fail-over" capability also covers extruder malfunctions, but it might depend on whether the malfunction was detected quickly enough.
Fast detection isn't an issue with regard to running out of filament because that's actually detected before you run out -- as a result, the printer knows precisely where to pick up laying down filament with the other tool. Not sure other malfunctions would give you the opportunity to do that.

I'm a newbie, but I'm kinda surprised...kinda not surprised, that the extruder motor must not be encoded?

I can't speak to the extruder motors, but the steppers on the X, Y and Z axes are not encoded.
They don't need to be, unless you have a collision or your belts are so loose that they slip.
Problems like collisions or jammed filaments are, I believe, detected by monitoring the current to the steppers.
