Man this is so much fun....
I did not change anything....
Anyway - I do not know if it is my Y or X axis because I did not mark the material. I cut a 2"x2" square and it ended up being 2" exactly on one side and 1.98" on the other side.

That is pretty close.

Is it worth trying any further or do you think that is close as it gets?

Thanks -
Keith

Thanks again -

With 1 FULL STEP and all the other stuff mentioned before - I am usually right under an 1/8" short almost every time. Frustrating

I have always left it at the default because I never knew what to change or what I can change things to.

Thanks!!!!

How does velocity and acceleration affect steps or does it even matter?

I have it set to 1 FULL step -
I have options for 1/8 or 1/2 and something else, but left at 1 FULL step.

What is better - Should I change it 1/8 or something else? Is one better than the other?

Hi -

I am not new to CNC but I am new to setting up some of these settings in Mach3. How do I calculate steps per inch in Mach3? I am not getting accurate when I use the setup wizard thing.

I have a DIY cnc machine

My board is set to FULL step

1/2" 10 tpi ACME screw rods.
Direct drive
Kelling KL23H276 bipolar stepper motor
NEMA 23
Dual Shaft  Front shaft=1/4" x 7/8"  Back shaft= 1/4" x 5/8"
200 steps per revolution
1.8 degrees per step
No. of wires=8
Bipolar series Volts=3.86,  Amps=2.1, Ohms=1.84, Holding torque=2.0 Nm. 0r 282 oz-in
Bipolar parallel Volts=1.93, Amps=4.2, Ohms=.0.46 Holding torque= 2.0 Nm. or 282 oz-in


THANKS
