Success! Everything working great. Smoothing really helped. Cuts to 100ipm are smooth and fast enough for my hobby needs. Thanks again guys.

You can build a z axis that is engineered by you to fit exactly what you need.

Thank you to all who responded to this post. I built a new computer and currently testing. So far, able to cut at 50ipm without problem. No errors. I tweaked the deadstop and delta setting a bit to prevent banging with direction change that I think was contributing to the problems. Mine defaulted to ...

Machine basics:
Roughly 24x48in
Ballscrew direct drive 5mm pitch on all XYZ. Dual driven on Y. Software pairing. HiWin and generic rails.

What happens if the CPU doesn't meet specified single thread speed mark of 1500? Are their any hallmark behaviors to look for? My HP all in one only scores 1200 on the CPU PassMark list and I would like to blame it for random errors. This is what happens...I can cut a part out perfectly then on a ...

Just want to pitch in since you are using AutomationTech drivers. I have found on my current build with KL8060E's that the 5v logic can cause some headaches. And here is a suggestion to all using these type drivers. The 5v logic needs to share the common with Acorn board/PS. I believe the reason ...

Does anyone have the axis pairing and squaring guide for CNC12 4.12? I found a great guide for 4.14:
