What servos did you get? I am spec'ing out a 4x8 pro machine and want to do acorn and clear paths. I read on one of the threads in the facebook group that he had to upgrade to the high resolution motors because the 800 steps/rev models didn't allow for proper smoothing with the acorn.RogDC wrote: ↑Thu Feb 11, 2021 3:53 pm I built an Avid CNC Pro 6072 with Acorn and Clearpath servos and CNC Depot S30C ATC Spindle following many of the recommendations on the forum.
The system has been performing well, just make sure to install the resistors on the Teknic control cables if required and follow proper grounding and shielding practices and use RF Filters where required.
Thanks so much for sharing. Looks great! I looked through the entire thread and may have missed it, bit would you consider posting a photo of your control panel and/or a summary of your design?paulwall wrote: ↑Fri Feb 12, 2021 9:25 pm Here's my 4x8' success story. I was a complete novice with no prior CNC building experience with exception of some minor start/stop running operations at a previous job. I built the controller up adapting it to an existing machine platform, and though it was a lot to take on, the information is all out there, and the system worked flawless.

I have 2 instances in the field where the "Step Input Timing Error" does not occur when the VFD is powered down. (Delta VFD & low rpm motor)The ClearPath motor inputs are optically isolated and current limited. This design provides exceptional noise immunity even in the most difficult EMI environments like plasma CNC machines and applications that use a VFD.
Yet the Teknic supplied control wiring is now appears to be twisted pairThe optical isolation hardware of the ClearPath motors provide enough noise immunity that shielded and twisted pair cables between the CNC motion controller and the ClearPath motor are not required.
I’m curious about this as well. Do those panels have the recommended pull up resistors installed?Gary Campbell wrote: ↑Fri Feb 19, 2021 10:56 amI have 2 instances in the field where the "Step Input Timing Error" does not occur when the VFD is powered down.
