I set them using the "Set steps per unit" feature, under the settings tab. It's like they're X10.Quote:

The co-ord stuff and scaling is sometimes iffy.
Mostly, it is not wrong, necessarily.
If the machine was set up with a certain abs. position, homed, then you use a different offset g54xx, it is unclear which units should be used.
Since the work co-ords are not tied to a scalar, how is the sw to know what is/was the correct offset base in global terms.
If a work co-ord is offset say 10,0 mm, and I switch to imperial, should the offset base adjust by /25.4. Why ?
Likewise, should the machine global values adjust, or not ?
Why ?
If the home switch in z is offset 10.000- mm in z, metric, and I switch to imperial, should the home-pos value adjust ?
If I read in the value into a parameter say #3000, should that number adjust ?
Why ?
I am NOT saying it is right, logical, correct.
What I am pointing out is that it is very complex with no clear right answers, mostly.
The UCxxx, and the chinese offline controllers, are mostly much less complex and donīt support a lot of the features in gcode.
Good call Clive!
I rarely think of the basic machine set up being at fault! :D
I got it figured out! It was an extra decimal point. i.e step per was set 2000.xxx instead of 200.xxxQuote:

Appreciate your help, everyone!
Now the step per is resolved, I need help to figure out why everything except square, rectangle, and straight lines come up deformed.
The shapes below were supposed to be 20mm circle, and 20x20x20mm triangle.

Could be missing steps ie. acceleration too high or voltage to the steppers too low. Or even excessive backlash. Or couplings loose on the motors.Quote:

Glad you got the steps per right now.
How to sort them out?Quote:

Well you was sure the steps were fine before. Post a pic. of the machine also what drives and what is the voltage supplying them. What is the acceleration settings in Mach.Quote:

We don't have crystal balls to see these things.
Yours in the shop for repair too? ;-)Quote:

Don't tell me the crystal ball I recently purchased from the pawn shop was yours? lol
Thanks for taking the time to help!
