Setting my table up...

Brilliant, that's exactly what I was thinking too.

the reason I asked is that many threads go on about tuning for high speed, must go this speed etc. but then I realised that plasma itself is limited (at least in home size machines) to speeds of around 750 to 4500mm/min so what the heck is the point of mega speed.

as you said, acceleration seems to be important and on a machine with an envelope of 600x600mm, 20,000mm/min is pretty scary and damaging.

i think I'll limit mine to 5000 max.

Bragging rights and showing off that's all there is to why they chase Rapid speeds.!!

If your working with small machine for cutting woods then I'd aim for between 8000 to 10,000mm/min Max Rapids. If cutting mostly Aluminium or hard materials then you won't need much above 3000mm/min and 5000mm/min is a good Rapid speed.

Also Resolution is important so think about that when building a machine.
