Axis position shift during helical boring - Fusion 360 Personal + Mesa 7i96s + C

Running the ClearPath motors in quadrature mode is free, same wiring and everything. AFAIK there are only upsides to doing so- your fastest signal becomes half as fast, so you gain margin, and noise is less likely to accumulate into "permanent" errors, more likely to jitter back/forth one step. Which is still bad, but less bad.

Even if that has nothing to do with anything you're experiencing, I'd still advocate for it as technically better.

Hi maruf1777,

I’m an engineer with Teknic and I came across your thread. There are a lot of good recommendations from other users, and it looks like you’ve got some solid next steps to test. If you want direct help from Teknic, feel free to contact us at 585‑784‑7454 or www.teknic.com/contact/ and one of our engineers will be happy to assist.

Also to build on dbtayl’s quadrature note: when ClearPath is set to quadrature input, it treats each edge transition on the A and B signals as a count. So if you keep the same command resolution (counts/rev), the required signal rate on each line is actually 1/4 the pulse frequency you'd need when using step & direction. If your Mesa card supports quadrature output, you can set ClearPath’s Input Format to Quadrature in ClearPath‑MSP, which can help if you’re running into pulse‑rate limits or signal‑integrity issues.

Best regards,
