Aspire or Shopbot problem?
I am running a large sign foam sign on my Shopbot PRT Alpha with a 5hp spindle. I am using a 1/8" ball tip bit at 175 inches per minute. The component that I am running is a 3d wood grain running in the X axis. The problem is that I am getting ridges running in straight lines on the Y axis. about a 1/8" apart along the entire length. I'm having trouble loading pictures, I hope to get some on here

Re: Aspire or Shopbot problem?
Does your toolpath preview show the same ridges, or is the preview "clean"?
Are you certain you are using the same bit specified in your Tool database? (Make sure the bit specs in your database match the actual bit used when machining.)
There are many possibilities that can cause lines/ridges in your carvings, but we can start eliminating the basic causes first.
Photos and a peek at your file will help us help you.

Check the rack to pinion lash on the Z, it looks like it might need adjustment
Check them all while you are at it

Re: Aspire or Shopbot problem?
Was a little slop in the Z axis, but it still had the ridges in the Y axis. A post on the Shopbot site made sense that it could be worn rack and pinion. Moving the X axis carriage without power off I can feel it wasn't to smooth. So I have new spur gears on the way.
