Default "Wobbly" Cuts with Panther

I'm getting some inaccurate cuts that I can only describe as "wobbly". I see them in ovals, straight cuts, 3d contours, pretty much everywhere. Can anyone share a link to a video with some basic maintenance tips, like how to check belts, etc? We've been running our router for about a year in a production environment for about a year with no issues except this one, and it seems to be getting progressively worse. PT-408 cutting poly tool board and various plastics, wincnc post out of RhinoCam. TIA

Loose belts can absolutely cause that kind of behavior...I had the issue with my Stinger II and it was because of a loose x-axis belt. I later found out the right side y-axis belt also needed to be snugged, too. I've started to check them about every other lubrication interval now. Some folks may want to check more often...my machine isn't running constantly due to the nature of my business being part time and not solely focused on the CNC.

I've got the same issue with my Panther. Michael @ CAMaster helped a lot with various tests, etc. I ultimately replaced the transmissions on both Y axes and the X axis. This reduced the severity of it significantly, but it's still there. My latest theory is an issue with the X or Z bearings, but I haven't come up with a good way to test that, short of replacing them all.

I particularly notice it when cutting letters/signs in HDU foam. I almost always have to hand sand the curved profiles to smooth them out.

I'll be watching this thread - please share when you find the fix :-)
