Myth or reality?

Inductive proximity home/limit switches including dual ones to auto square the gantry each time you home.

It is a very good idea if you are using two motors to drive a gantry, especially if microstepping, as the motors may take completely different positions when first turned on.

Could you put up the speaker build up link? I would love to see how those turned out, are you on DIYaudio.com?

I was just reading about this today. 3d routers that only use a master, and a slave stepper motor do shift a little, and it shows up as a stepped cut. A timing belt connecting two lead screws with one stepper motor fixes any shifting errors for the most part. I'm presently trying to figure out how to use 2 motors, master/slave, and a timing belt between parallel axis to work in harmony, (some thing needs to slip during tuning).

That's all there is, pretty cool though.


So is it possible to programmatically square up the build envelope?

I found the build log here
