Eddy,

If you have not done so already, then it may be worth trying the WinXP Optimization steps detailed here http://www.machsupport.com/downloads.php

I think that a fresh, clean, install may just solve the problem (I sincerely hope so).

I look forward to hearing of your progress.

Any way to tell from specifications if the pci card has a 3.3v or 5v output? 

Perhaps not from the spec. but if you hook a voltmeter between any axis output direction pin and pin 25 you will get a reading (Approx. 0V when you jog that axis in one direction and 5V when you jog it in the other). If you only get 3.3V then, as already said, this could possibly be the problem.

Couldn't say one way or the other if that box is OK - certainly the bay description sounds good and the price is good as well but the overall quality will be an unknown.

If you want a quality product with excellent documentation and backup then the Gecko drives take a lot of beating http://www.geckodrive.com/geckodrive-step-motor-drives.html but there will be UK import duties / vat on top of the price.

Does you existing controller look like this one ?

Hi Dave,

I am pleased that you have found the problem. 

Perhaps if you post a couple of pictures of the inside of your control box someone may know of a suitable replacement for the defective drive (assuming that the seller does not come up with the goods).

Sounds like it could be 'crop circles' - In Config / General Config set the IJ Mode to the opposite of its current setting and see if that corrects the problem.

Tiny spikes are OK so it is unlikely to be a PC related issue.

Looks like I have just about exhausted my ideas on this one for the moment, sorry.

That’s not any help so looks like you will have to leave the motors running hot until you can get some further information.

Something else you may wish to check…

In the Mach3 folder is ‘DriverTest.exe’ – run it and see if the result is a nice straight line.

Excuse me being a newbie but how do I reduce the drive current lol.

That is a function of your driver board - you would need to check your manufacturers instruction manual for how to set motor current.

What driver do you have ?
