I'm going to transfer my parts to a bigger and more rigid kossel. This thing moves WAY too smoothly and awesomely. You guys are right. 😃

@jannisj:

where did you get that hotend mount for the anycubic effector?

-Jannis

I got it custom milled for me, sketched it up in CAD. I used the holes in the effector plate with stainless standoffs and had it machined to fit the hot end nicely.

The amount of retraction you need depends on the length of the Bowden tube. With no Bowden tube, 1mm is probably enough. Otherwise I find about 1% of the Bowden tube length + 1mm about right, using 1.75,mm PLA. I set the retraction speed high, typically 3600mm/min.

Added pics to the my setup section. Prints are working great, but I need some more build tak. Had some collisions due to some mechanical issues. OOPS.

Thanks Jeff!

@T3P3Tony:

Its good that Tim is sending you a new board. I would triple check the wiring on the axis that the driver has blown on, especially look for any possibility that it could have an intermittent fault (for example if it moves or if something moves against it).

I'll second this one strongly. In the case of these drivers and most others an intermittent connection kills them faster then a dead short. The coils in the motors have some pretty nasty flyback voltages.
