Hi all,
I know this has been asked before, and I've searched, but I'm still having some problems after upgrading. I have a Shapeoko 2 that I've upgraded to the acme screw and belt drive nema 17. I'm having trouble figuring out my 3tr setting. The acme screw is 12 tpi, with both GT2 pulleys with 20 teeth and 2mm pitch.
With both pulleys the same it's a 1:1 ratio, so it's the same as a direct drive, correct? So the travel per revolution is .0833in or 2.117mm?
I'm having a problem tuning the z axis. I've tried the recommended shapeoko settings from the wiki but when I try to jog the z axis in chilipeppr, I miss a lot of steps. I've tried tuning the voltages on the axis, but it goes from not enough power, to missing steps.
I've tried messing with the search velocities based on what I've seen from other people's $$ dumps, but haven't had much success. If someone could take a look at mine and point me in the right direction, I would really appreciate it.
