Changing the steps on X

[srcnet]

I’m assuming this is on your LR4. Are you using the same 20T pully from the LR3?

Lowrider cutting wrong size and angles

Your pulley must be a 20 tooth pulley. If the steps are set at 100, you need them to be 80.

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.
