Resolution calc help needed for Mach2

[Moondog]

Ger... so by the looks of it.... even with no Step Multiplier reduction I should still get reasonable IPM's?...

Initially I'll only be using a Makita router. Hope to then upgrade to a HSD Spindle.

If all your calculations are right. I only looked at the 180 steps/mm, I didn't check the rest. We've got 2 9HP HSD's on our machining center at work. I cut 3/4" plywood and mdf in 1 pass at 400ipm. (The machine won't go any faster, or I would )

I caculate:

0.0055mm per pulse
multiply by 45000 pulses/second (0.0055*45000) = 247.5mm/second

Divide by 10 to get cm/second = 24.75cm/second

Divide by 25.4 to get Inches/second = 0.974 Inches/second

Multiply by 60 to get Inches/minute = 58.5 IPM

Maybe I'm going mad.

If my X drive is .005555 mm per step. then for say 300 IPM i need.. 300 IPMinches = 7620mm per min... / .005555 = 1,371,737 steps per min..... half of mach 2 output... my Y is less than half the X..... so I still have 1,320,000 approx for my Y & Z... does that sound right?..

300 inches is 7620cm, not mm.

Terry, divide centimeters by 2.54 to get inches. Multiply your ipm x 10

[MrBean]

Yep I'm going mad........HAHA.

I'm out by a factor of 10. Ooops.
