My x axis seems to be cutting "wider " than it should … when i got to measuring the movement i have realised that it moves 12mm instead of the 10mm movement alotted in the FluidNC job.
what is the easied way to rectify this issue
I’m assuming this is on your LR4. Are you using the same 20T pully from the LR3?
You can update steps_per_mm in the config.
I’m also assuming you measured this with an endmill that comes to a point on tape or against a ruler. If you are trying to measure this as the output of a cut job, there are a million other things that could be off.

hey , you are correct on all. Yes I measured using engraving bit and a measuring tape.
Ok I’ll go look for the steps per mm in config.
how ever i am using the Jackpot board now.
after checking FluidNC config. I see /axes/x/steps_per_mm which is set to 50.
Please double check my work. You should be able to test this, and revert back pretty easily though.
New Steps/mm = (Old Steps/mm) * (Expected Distance / Actual Distance)
New Steps/mm = 50 * (10 / 12)
New Steps/mm = 41.6666666667
Note that to reduce the total error introduced by measurment error, you want to configure steps per mm by measuring much larger distances than 10mm. Ideally you want to measure the longest distance possible for each axis so that the error value shifts by a couple orders of magnitude.
