Review on 400mm (15.75 Inches) TR8X2 Thread Printing Machine by Larry Blanco

This is not Precision Thread Play Assembly. I had to remove them as they were rough. This in turn led to poor printing results. The spring creaks, probably brass? Parts move in locking grooves. Maybe if I change them enough to remove the roughness? Yes I have used them with 8mm pitch, 2mm pitch and 2mm lead screw. On the other hand, it turns out that the controller cannot function smoothly or at all. You need to be able to run at such a high speed that the stepper/controller just gives up. Maybe there is a way to fix the firmware. Game nuts are quite disappointing.
