Many thanks for the response and reaffirming recommendations on this and other threads.
In short, I checked square/level, the belts and pulleys are installed correctly, adjusted one v-wheel on the left Y carriage and increased the power to the y channel of the shield. Made several test runs on on 3/4 pine and all appears to be working except for depth. Transitioned to 1/8 Birch and all but depth appears to be working.
So as of right now there is not stuttering/chattering from the left side, cuts start/finish as expected with no off set, and the machine returns to home (of the material) as was another issue experienced yesterday. Its just the depth at this point. Confirmed I'm using the ACME Delrin kit and ensured the hardware/software reflects the configuration and in inches. Just baffling at this point.
Easel dug too deep with easel created shapes. Imported SVG from VCARVe and experienced the same. Tried the VCarve to UGS route and I have to home the bit on the waste board just to get it to cut into the material. Trying to reduce the variables at this point and focus on getting Easel and X-Carve to work correctly, then take on VCarve, UGS or Chilipeppr.
UPDATED: Cut a few project items out of 1/8 Birch plywood with the same thickness of birch underneath to preserve the waste board. Lesson learned--clamping down the outer edges will compress and throw off the cut depth to the outside and potentially bow the material upwards (without too much issue) towards the center. Investigating double sided tape but both sides of the project cutouts will be visible. Somewhat worried about gumming up the wood and creating extra work for what could be a couple thousand small pieces in a short amount of time.
Issue 1: Deep cut on first path still plaguing the operation. I've had to reduce the cut depth to between 1/16 and 1/32 so as not to completely dig in and rip through the 1/8 work material in one pass.
I shouldn't have to use Kentucky windage and can't create tabs without putting this depth (z axis) issue to bed.
