Help newbie with linuxcnc on stepper wizard

good price on the part

as tod sugest
1/8 woudt be best for you
1/4 woudt also do but not on the tb6560 available only from tb6600

so it is
8 times the stepper steps per rotation value =8*200 =1600steps/steppermotor Rotation
the pinion got 12 teeth at 0,1571 per teeth a Rotation diameter in Action at 1,8852inch per rotation of the pinion

so it is 1600steps per 1,8852inch = 848.82636steps/inch.

The 0.54 you estimated for the revs/inch is (if you want it exact)
The number of teeth on a 1" pinion (20) divided by the number of teeth on your pinion (12). then that number divided by the distance traveled by 1 rev. of the hypothetical 1", 20 tooth pinion (pi or 3.14159). Approximately = 0.5305.

Sweet thanks a lot guys for the help!! I am trying to get the hang of linuxcnc and when people say that they edit the .ini file I am trying to figure that out also. I am trying to cut something with no THC for now but what do you all think of the post and processor that you all use for no THC?
