Need some help on configuration Plasma

The first cuts are a fact:


Need to fine tune a lot

But the problem i have is to set the correct value's in stepper config wizard. The demensions are not right.. its about 10 : 6.

My set-up : DM542 stepper drivers , 23Hs9430b Longs stepper motor. GT3 Belt 20 tooth pulley.

I have set the stepper drivers to 400 pulse/rev. So in the wizard i entered the same. + 2 driver microstepping
Pulley teeth : 20 : 1 i am guessing.
Leadscrew Pitch i have no idea how to calculate. The toothpitch of the belt is 3mm

I think it is sometimes just easier to make a command move such as 10" and then measure how far the machine actually moved.
Compare the two and see what percentage off they are and then make the correction to your SCALE and measure again.

If you have a 20 tooth gear on a 3mm pitch rack (essentially what you have on a belt drive) you'd have 60mm/rev. 400steps/rev / 60mm/rev = 6 and 2/3 steps/mm for your scale. (You might what to consider adding further gear reduction.)

That makes sense. Probably up the steps/rev than on the driver.
