Pat,
Any update you can provide? I have just started experiencing this problem.
Mick
What problem are you referring to?
Pat
You changed your stepper motor settings. How is that working for you?
Mick
No issues, I would recommend changing the PPR to 2000 instead of the 400 that 1F sends them out at and also reducing the acceleration by some amount, this is pretty subjective so it is more by preference, there is no one setting for everybody, too many variables.

Hi Pat, thanks for the clarification. What did you change the acceleration to? I may just make a single change for now and see how that works.
Glad things are working for you. I’m not new to CNC’s. Onefinity is a robust platform which is one of the reason’s it sold me on the unit. Also, the Masso is very simple to use compared to Mach 3.
Thanks!
Mick

I used to run all Mach 3 and you are spot on , the Masso is much easier to use and set up.
OK all my Axis were 19.6 Inches per second acceleration, I first tried 10 IPS and it slowed the machine down too much, I ended up with 18 IPS on X and Y but left Z unchanged and this worked for me, you may find you are OK with even less on X and Y it really depends on your table and setup.

We will be issuing an official service bulletin changing the prr from 400 - 2000 from the factory in the next month.
Feel free to change the prr now.
After much internal testing, working with masso, and customer feedback, 2000 prr increases resolutions, removes the “grinding noise”, adds increased smoothness, and leaves no noticeable loss of torque.
To do this, with power off:
Change all motors:
Turn 1 and 4 dip white dip switch to off/down. All the rest leave on/up.
Go to the f1 page. Change all axis settings digitally on the prr lib from 400 to 2000 to match the dip switch change and hit save.
Reboot and enjoy a much smoother machine.

I very much appreciate the help especially on a holiday weekend for many.
Thank you!
