Had a go using motorcalc sheet but does not look right.

Clearly the value for G0 is different than that for G1.... what value do you have for G1?

Now there's a question! I'd just wired up the new drivers and ran the last job on the computer for a look see. The X axis is in reverse.

Probably 1.5 mm/s, I usually cut between 1-2 but I might drop to 0.8 for a plunge.

When the cutters get long and spindly, even slower.
