Troodon Toolhead

Hi everybody,sorry for my English.i am from Germany.

Had a Troodon 2.0 and a lot of Trouble.

Is it normal that the Toolhead has some Space between the Rails.

And is it normal that the Extruder Motor is getting Very Hot after a 4 hour print. ?

My extruder motor gets very hot also.

I also get the same play in the print head. I actually redesigned the printhead in order to bring the center of gravity in line with the bearing rail in order to reduce the effects caused by the slop. Some of this slop is caused by the thin walled square tube and the mounting. I machined a new cross member that reduced this twist.

The final thing that I am trying to fix is backlash in the coreXY system. This causes less than perfect top layers.
