I just completed my JGRO router but I am having problems cutting. When cutting with multiple passes each pass seems to be off ~1/16 to 1/32", x axis only, the y axis looks great. It has a stairstep effect. I am cutting 3/4" pine with a 1/4" spiral upcut, .25 per pass.
I used a dial indicator to move 1" then back to 0, it was off ~.002. If I try tighten the antibacklash nut anymore it starts to bind. I tried the backlash setting in turbocnc but didn't have any luck.
I am running turbocnc with 5/16 all thread.
