The illusive Boxford 260vmc

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.

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.

[i2i]

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

[i2i]

it will be slower as it's a fifth the amount of steps, but it's the RIGHT AMOUNT OF STEPS PER UNIT.
This must stay at this setting.

Next step is to set the jog rate at 100%

Press "tab" to get the mpg screen and set the jog rate to 100% (just below the "slow jog rate")

[Ricardoco]

Ok it was already at 100% :)

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.

[Ricardoco]

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

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.
