Do not worry about not having enough power, your motors are already way too powerful.

1 Nm of torque onto a 5mm pitch screw gives you 280 lbf of thrust for cutting.

If your gantry weighs 50 lbs that 1 Nm would give you over 5 G's of acceleration for the rapids.

These drives and motors should be more than enough for the gantry but SW mass properties says my gantry is about 42kg / 92 lbs ( Wow!!!!.....hmmm! ) .
Ive got Mach 3 setup and the drives are running and heres the " but " there doing my head in !.
So on my metal mill BF25 Ive installed Zap 425oz on the X and Y Axis and a CNC4you 566oz with 2:1 pulley reduction on the Zaxis. I'm running the AM882 at Peak Current 3.6 Amps , 800 step mode which works fine apart from the X axis which " SQUEALS " like a little piggy to the point that i have to turn it off or i couldn't think. Why this drive and motor squeal and yet the Y axis on the same settings is quite as a mouse is doing my head in. Ive tried all the step settings , 4.6 amps but it makes no difference. So Ive walked away from the dam machine for abit until i can buy some ear plugs!.

So I'm open for ideas!.

And yep your gun is bigger than mine ! ..... alot bigger !
