New build with recycled parts on a ridiculous budget 120cm*60cm work area

[Desertboy]

20 revs = 50mm pitch surely not.??

Khz = (steps per unit * velocity in units per minute) / 60

So Break it down into mm units not meters. So lets work on 10mm pitch with 1600 micro steps.

1600/10=160 steps per mm

160 x 10,000 mm/min= 1600000 /60 = 26.666Khz

LOL that's why I need to check it was having a blonde moment ;)
