Thank's for the reply. My steps per unit is set at 1800, the velocity is 35 and accel at 30 on all axis. Where is the scaling located? I can't find it. Also the settings screen shows inches.
I did a small test carve simulation of a 2" letter and it was carving one about less than half that size.
reguarding your steps per unit, lets figure it out to make sure its right, steps per unit are calculated starting with the number of full steps your motor turn, commonly 200 but could be different, time the number of microsteps you have the drivers set to, then the number of threads per inch your feedscrews are. EXAMPLE, my motors are 200 steps per rotation, I'm using 1/4 microstepping and my feedscrews are 10 tpi,
So In my case 200*4*10=8000 steps per inch....
the scaling dros are to the right of the regular xyz dros on the main screen, should be set to "1"
