I am currently running the VEXTA PK296A2A-SG7.2
I was having an issue with a small amount of chatter in my cuts
so I switched from running the 20 tooth gears to a 30 tooth gear
thinking the bigger dia. may smooth out the cut with more gear contacting the rack but what happened was I ended up with more backlash, I wasn't surprised I thought that this might happen, but I didn't think it would be this bad, and I was wondering if anyone else has had the same issue??
the backlash on the Y axis is about 13 thousands of an inch
and on the X it is 7 thousands on one side and 20 thousands on the other
is this a normal amount of backlash?
I was wondering if I am expecting to much from the machine?
thanks
