    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.

    i normally use 1500 for velocity and 50 for acceleration

    You can of course increase these settings, velocity gives you speed and acceleration defines how quickly you get to that speed. Too much acceleration and it'll stall so be gentle with the acceleration.

    I've had the boxford running at 3000 on the velocity, which is 3m a minute, but you risk stalling the motor that way, that's why i stay at 1500.

    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.

    The motors Sound good (they sound right) at 1500 and im not in any hurry for more speed.

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

    i've not used the stepper drivers you have, so i don't know their limits. The settings i've used are for Parker sd2/3 drivers.

    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

    buy yourself a cheap tacho (ebay 7 approx), or use the pulse to set the speed range to match mach correctly.

    you should get at least 3200 rpm from that machine.
