Just ordered my a linear z axis but after ordering it I noticed it is 3/8- 16 instead of stock 12 tpi, is there anything I need do when calibrating? Thank you
You’ll have to calibrate your steps
The number of steps depends on the following items:
Stepper steps per revolution, number of microsteps, ACME number of turns per revolution and gear ratio.
Or if the only deveation is the number of turns from 12 to 16 you have to multiply the actual value by 16/12.
I will be not using a belt, it will be direct from motor to acme screw using a coupling.
I’m really wanting to do this as well, and judging from a few posts I’ve seen on here so are a number of others, so please keep us updated and please lots of pics!
