NC Studio cutting double the size of simulation

[phunmmie]

Hello,

I have a 1325 cnc router and I noticed when I load the gcode, everything simulates well but when we proceed to cutting the router cuts double the size and the machine cant complete the work.

I do not know what I am doing wrong,

Check what your actual stepper drivers rev (microsteps) are set at and check what your stepper motors rev per units are set at.
Seems to me that you have the steppers set at half what they should be at (I think it's that way round anyway) making them travel twice the actual distance required.

For example: (in mm)
A 5mm pitch screw.
Stepper driver at 2000.
So 2000 / 5 (driver / by scerw pitch) = 400.
Stepper rev per unit should be 400.
Then do the fine tuning.

If stepper was at 200 using the above example it would go twice the distance on the machine.

Thanks Dazp1976,

Apologies if this seems like a silly question but i am currently looking at all the settings and cannot find the settings for the stepper drivers. Can you please point me in the right direction based on the settings i set.

Thank you so much for your help as I have been at on this for 3 weeks now

Not silly. I don't even know what controllers/steppers you are using.
I'm talking about checking the drivers in the control box itself to see what they're set at. Such as:

Settings are determined by what the little white switches on the top are positioned as.
Then do the math to check your steppers.

Yours may be entirely different but it's the first thing I could think of.

Could be the calibration of the software,but we have no information about the software in question.Very probably you will find a DIP switch on the controller that can be moved to double the number of microsteps per unit, but equally likely you would be able to alter the steps/unit of travel in the software settings.Knowing the type of software would bring forth the information about where the calibration settings are located.
