Limit axe problem.

Clement

Configuration of limits axe not working correctly?

I have a CNC and I am using Duet ethernet. (Cartesian)
Home routines work good.
But when the CNC moves for example on the X axis (G21, G1 X250 F1800)
The CNC stops at always at 203mm and not 250mm?
The maxima is 203mm, but I write X279.4
M208 X279.4 Y346.075 Z136.525 S1

I think you have those reversed.

Snnn 0 = set axis maximum (default), 1 = set axis minimum

thank you, this is resolve
