started the plaque for pop for fathers day yesterday morning. seemed to be going ok. it had generated 447k lines of code, and was cutting rather smoothly, when i left it had gone through over 115k of the code. then i had to go to a fathers day to-do at the wife's church was putting on. when we got back about 6 hours later, it was still going, but instead of the smooth moves it was doing, it was moving in fits and starts, from a little over 1/8 to 1/2 inch. it was following the path it was supposed to, but real herky-jerky like that. i'll be putting in a call with the shapeoko people today, any ideas here? almost forgot, when we got back it had roughly 206k of code to go before finishing.
