Yes, the buildthread... I will get to that. :-)

A. When i think about it i begin to wonder if home and zero is the same thing?
I dont really know how to ask without making things complicated but what i would need to understand is the basics.
For example, you make a part in Fusion 360 and you have origo or 0. Will that also be the 0 for the machine or how does it know?
Further more is home for the machine just going to the end of all axes or is home that zero point?

B. It makes sense, Zero would be my indexpoint. It knows where it is and it can return beacuse it counts the steps all the time.

C. The function is there but they are talking servos, not hybrid steppers but it makes sense that it would work.

D. Will do, thanks!

By the way, had a look at your thread and i like your design. Its about the same type as mine.
Really like the "Epoxy project". I have been thinking about that myself in another project.
