I take it you are going to fill all the holes and block in the open end.

Could be costly if the probe shot down the slot.

Is the LPT 3 volt or 5 volt on the output pins?

Have you copied your licence file onto the new computer?

Put a G61 at the start of your g-code, that should stop the rads.

You don't have a g41/42 in your start up string in config do you?

can you post the code that is giving the size error?

What are you using for homing switches?

At the end of every run is the machine sent back to the home position?

Yes, its to do with the incremental input,  if you highlight a DRO and press the + key and enter .1 it will add .1 to the value, if you press the - key and enter .1 it will minus it off the value, for it to work the format string must have the + sign in it.

Lets start at the beginning,

what version of Mach are you running?

What is your machine?

How are you creating the g-code?

Hi,

is the error proportional to the size of the part, i.e. is it getting larger on a bigger part?

Have you checked to see if the sides of the part are square not tapered.

Are the scaling DRO's set to 1

Have you a stray G41/42 in your code and a offset in the tool table.

If you milled a hexagon or octagon would all sides be to big?
