I’ve been using a smaller cnc for almost a year. I’m using the same files with the same feed settings and this is showing up on the Woodworker but not my other machine. I have the file set to run at 75 IPM. Any other ideas as to why this is happening? ---

Assuming you mean the ribs on curves… If your other machine supports arcs that may be why. Alternately if it doesn’t it may be a setting around arcs and deviation you can adjust. ---

Thank you, yes the ribs is what I’m referring to. Is there a setting on the 1F controller for arcs? ---

Searching the forum for"arc" should give you some good reading. Here is the first reflux which should get you what you need [Lets talk about ARCs and Circles](https://forum.onefinitycnc.com/t/lets-talk-about-arcs-and-circles/6820) ---

I just read that thread an posted a reply there. Unbelievable. What a kick in the gut. ---

FWIW, I followed the suggestion to set the Max-Deviation setting to .0005 and my issue went away. The cuts are real smooth now. I’m seeing the cuts take a little longer, but not a big deal at all. ---

I think you may need to step back and try some settings changes. There are plenty of folks proving this machine can do almost anything and guitars are definitely in scope. ---

Great to hear! The platform is great and I think to many folks think it is like a cricuit or other boxed simple machine. While you can definitely use it out of the box there are settings to make it work better for your use case. ---

Yes, you are correct. Thank you! ---

Hello LarryF I am new to Onefinity, and I was cutting some 6 in diam disks and had a similar problem. Could I ask, where exactly do you change "Max-Deviation setting to .0005 "? is this something that is done on the onefinity controller? I am currently using Fusion360, and I do have circular interpolation turned on in the post window. ---

It’s in the controller. The flyout menu is on the upper left; click that and choose Settings. Scroll down to about the middle of the page and you’ll find the Max-deviation setting there. It defaults to 0.05mm. I set mine to 0.0005mm. When you click outside the box after setting the number, a green Save button will show up in the upper left hand corner. Click that and try your file. BTW, the setting **does not stick**. Every time you start up the controller you will have to re-set the Max-deviation setting. Please let me know how that works for your disks. ---

Thank you for your help. I made the change, and it is much much better, I would say almost two orders of magnitude better. I use 0.0005 on the ONefinity, as well as the tolerance setting in Fusion360. since I am machining aluminum, all those small facets were easy to see. Like the mirror pieces on a disco ball. ---

Very cool! Glad I could help.
