Understanding the different types of speeds

Mostly Printed CNC - MPCNC Advice

I have read the documentation but still trying to understand the differences. When moving the router is that acceleration or travel? I want to increase the speeds a bit and possibly the time it takes to cut. I understand there really isnt a chart to go off based on size etc. I just want to understand what i need to change to test different speeds.

Here is my current M503

How fast it moves when cutting is Feed Rate speed (G01 in g-code). How fast it goes when moving while not cutting is travel feed rate (AKA Rapid) speed (G00 in g-code). How quickly it reaches those speeds is acceleration.

The feed rates are usually set in your CAM program, those configuration max values are limits that the machine will not exceed, even if your CAM program tells it to go faster.

Your standard settings are fine as is . I don’t recommend messing with the max current, max feed rate or max acceleration settings unless you really know what you are doing, have a compelling reason to do so, and understand and are willing to accept the consequences when (not if) things go wrong.
