Hi!

Sorry, I use PCNC (demo @

Do You have a config-option for something called 'Accellerating Ramp' or similar?

Stepper can't turn full speed in an instant, and breaking is a problem, too. Maybe there ist a option for 'Start/Stop-Speed' also, defineing the speed the steppers CAN revv up to in a Blink...

You should start setting the first to maybe 1 rotation (eg. 400Steps for a 200steps/rev Motor in half-Step-Mode) and the latter to 1 rpm or the equivalent in mm/s.

If the problem is solved, You cane fine-tune by reducing th first and increasing the latter Value until Steps are getting lost... (and then some back ;-)

Hth, Michael.

P.S.:I'm not a native speaker, so excuse me for using some strange words ;-)

Are the stepper motors being driven by the PC directly, or is there an intermediate microprocessor?

If by the PC directly, then you may need to set a minimum step time of the order of 1 millisecond.

There are ramping options, you can have ramping or exact stop mode an I have it on ramping. I have found a setting called feed over-ride, i the help file it sasy if set too high it can cause the motors to spi faster than they should, which looks like the problem.

I also have another question :) When I tune the motors, should they b at a specific value in the steps per unit section?

Airy R. Bean, I believe they are run directly from my pc. I will have look into that as well :)

Thanks for the help

I found the problem, it was infact with deskproto. I went into th

milling machine options and noticed it had down 30mm/min travel. S obviously the motors were just moving really slowly! Once I bumped i up the machine was working well
