On going chinese 6040 problems

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?

All axis run free with the strippers removed with strippers removed

I could maybe use the stepper drivers I have and get a new PP based BOB. Or maybe replace the all in one board with a new all in one board. But what would you go for in each scenario

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

I'm pretty sure I got nothing regarding the micro settings. I got one sheet of paper showing how to put the parts together that was unreadable.
