Hi looking for some advice, build a DIY laser cutter, as you now there in no load on the x axis, so they swing fast,

Using 10mm belt 20tooth pulley nema 23 189nm wired parallel giving 4.2 amps, now I've seen some lasers running 500mm second and looks very fast, mine can 800mm second but does not look fast,

Now I can only set steps to 3200 any lower stalls and can only move at about 4mm second, so would changing the motor to smaller nema23 say 2amps 4 wire be better, or should I wire these in series, I used these as they where for a cnc but never used them so were spares,

Thanks for any help guys. Kev
