The illusive Boxford 260vmc

the only time you alter the steps is if you change the mode the stepper driver drives the motor, eg., half step 1/8 step ect.
But for now we'll use the settings the drives are on, which gives you 200 steps per unit.

you may want to lower the velocity a bit on the "z" as it's always a bit heavier on the stepper, 1000 or 1200 should be good.

Have a play around, don't worry about stalling a drive, at this stage you're not machining so best to find out the limits of the drives now.

don't feel too confident, you've got the spindle to come.

Well the spindle works from mach at the moment ive set the low speed to 320 and the high speed to 2000 rpm.. great fun lol

you should get at least 3200 rpm from that machine.

I wasnt sure what to set the speed to the spindle or the motor, it looks like 3-1 gearing on the belt or something like that. So i just set it to 2000..


Besides which how would i tell what speed it was doing :lol:

here's the tacho.

you may find it cheaper, or cheaper postage if you search.

I have one and they work perfectly.

:lol: as you know ive got a Tachulator coming at the end of the month so i can wait although i might just buy one of those as well, at that price im sure i can find pleanty of uses for it :whistling:

ahh before i forget how do you reverse the axis direction?
