I am just about a new as they get!  I just set up my mill yesterday and have got to fine tune it and got lost.  My set up is a Sherline 2000 mill with the Xylotex XS-3525/8S-4 Stepper Motor Driver Board w/ 4 269 steppers running Mach 3 of coarse.  The only problem I have had so far is setting up the motors.  What goes in the "steps per inch" ?  I spent a hour with the "set steps per unit" button going back and forth till I get it spot on and it will be goo for a while then for a reason I can not figure out will not even come close.  If I call for a inch on X ( g1 x1) I get .025.  Is this because I am running the DEMO? 

Next what is everyone else running there steppers at?  Mine are at 14 inch per min and that is as fast as I can get them!  Is this normal? 

Thanks in advance!!!

As far as steps per unit are
X = 31949.89958
Y = 32209.79736
Z = 32444.39823

I just spent the weekend setting my machine up and have a problem like yours.  I tune all my X, Y and Z spot on to 1 inch each and for no reason I can find the will go back to about .020 when I call for 1 inch.  I have had to re-zero 3 times in the first day of running anything CNC and know I am missing something.  I can not wait to here what others say about this.  I have been through past post and have not come up with anything yet.

I am running a Sherline 2000 with a Latex 4 driver and of course Mach 3
