General Mach Discussion / Re: Problem with Router not cutting consistently

I adjusted the accel to the sweet spot of 125. This improved the running of the router a lot. And seemed to improve the cut a little. but we are still having a problem I am going to post some more pics to try to explain the problem where it stands now. I cut it out of black poly on my milling machine and the lastest cut for the router I did in wood to show you the contrast. You can see in the pics that sum edges line up good and the others are smaller.

the accel is set at 180 do you have a suggestion what to change it to   also should I change the velocity from 250

How do I check the offsets?   I will try to explain the pics. The two parts are riveted together, when I do this the out side edge of each part do not match. I get something different everytime I cut it. It is the same drawing for each side. The parts lined up perfect on my other machine. It is like the steppers are losing a step or mach 3 is giving the wrong signal. I think I have eliminated this possibility buy checking the steps per unit with a dial indicator. So I am at a loss. Could the mach 3 be set up wrong The computer and mach 3 came with the router.

mach 3 verison R 3.00 is what I am using on the router I compared the part from the milling machine and the part from the router there is almost .250 difference in length

I just checked my steps per uint with a dial indicater it seems to be moving the same amount each time

General Mach Discussion / Problem with Router not cutting consistently

I have bought a 2X4 router and have completely rebuilt the machine it was very cheaply made. I was cutting ovals and it looked like I chewed them out (polycarbonate). Now I can cut a perfect (by eye) circle and it has a very smooth finish. One more problem to overcome, I hope. 
I am cutting polycarbonate. I am cutting two pieces that are to be assembled to gather. This is where the problem lies. The two pieces do not line up; the gears that go inside don't fit. I took the g-code and cut the pieces out on my CNC milling machine and they are perfect. So I am assuming this eliminates the g-code.  Info on the router; Mach 3 – steppers - rack and pinion - Bosch palm router.   Can anyone point me in the right direction of where to look.
