yes Clive the manufacture instructions say to set it to

steps = 320
velocity = 2000
acceleration 200

but if i go anywhere near this it stalls

i have to set it to

steps =320
velocity 1000
acceleration 100

and at this i still get a bit of grinding sound some time.

Ok Mike Unless you change the dip switch setting (on the driver) for the micro steps you don't need to touch that.
That setting is to set up the machine so that when you tell the machine move say 50mm it actually moves 50mm.
.
I would now move the steps to 1/4 which would be 160 by setting K1 and K2 (look the switch position up in the manual) on the driver and then change the Mach3 steps from 320 to 160. (re read EddyCurrent post #5).
.
See how it runs then. Just change one thing at a time. When you say grinding noise, are you running the motors on or off the machine? ..Clive

Hi Guys
I have been watching this thread and can offer no advise regarding the electronics/drive side, but would it not be prudent to disconnect the the ball screws and check to see if the axis are moving freely.
Just a thought.

I would have said set it to 4 myself but looking at the photo the options seemed to be 1,2,8,16 unless I've read that incorrectly.

In the video the motor was removed from the machine and just lying on the bench

I don't have a manual for this board. And I can't find one on line. So I'm not sure where. To set the switches. I'm guessing that k1 and k2 can be on or off. And at the moment they are both set to on? So I need to change this.
if I was to replace this board what would you go for?

Mike Is this the board http://www.aliexpress.com/store/prod...572788008.html what info do you have regarding the settings for the switches K1 and K2 As Eddy says you might have to try half step but we need the settings for the switches first.

You can of course use your other drives but Keep trying this one first. I am having to earn a crust this afternoon but will get back later The supplier must have given you some sort of instruction to set micro settings. ..Clive

Clive, picture 2 here shows the settings.

I see from your link Clive that K3 and K4 refer to 'buffering', I was thinking it meant standstill current due to the percentage symbol
