configs for 3/8- 12 acme for the Z

Postby REdington » Tue Dec 04, 2012 8:14 pm

I'm in the process of calibrating my ORD Bot and one of my 1/4-20 Z axis rod is bent. I machined up a new set of
3/8-12 acme rod and need to figure out the new configurations for it. I got 2.0866 mm per rev and with micro stepping
down to .0006520833 per micro step. What is the number I need to download for the new Z config.

Thanks for the help

Assuming 1.8 degrees per step, that's 200 steps per revolution.
200 steps per revolution at 2.0866 mm per revolution is 95.8497 steps per mm.
With 16x microstepping, that's 1533.5952.

So:

Code: Select all
#define DEFAULT_AXIS_STEPS_PER_UNIT   {78.7402,78.7402,1533.5952,665.665}  // default steps per unit for ultimaker



Edit: I'm sick, with fever, so take my math with a grain of salt.
