The illusive Boxford 260vmc

ok change the steps to 200, and try again

[Ricardoco]

Ok with 200 steps if i jog the Z axis from 0.0000 to 1.0000 i get a movement of 1mm. but slow.

[i2i]

to speed up the axis you raise the velocity, but the faster you go the more chance you have of stallling the motor and loosing steps.

[Ricardoco]

Ok thats cool what would you suggest for volocity and accell

[i2i]

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.


PS. see post 243.

Done

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.
