Couple of quick notes for other Newbies that may help as it took me while to figure out why my cut program stopped shortly after entering the workpiece. Thought it was laptop or USB shutting down - no. Though it was because i ran the program several times with many changes - no. Then i realized it took out the stock motor and installed a Dewalt 611. First i had to run out to my shop and lathe out the blue adapted block that came with the machine - from 65mm to 70mm. Don’t know why they shipped an adapted block and recommended a new motor that wouldn’t fit??
Turns out when i finally dropped the 611 in i set it too low. It was hitting the Z down limit switch and stopping everything. Had to disconnect the limit switch to get the thing to jog up. Lowered the new Router- problem solvied - wow!!
