Mach3 under Vista / Stepper motors move jerky and weird
« on: May 11, 2019, 10:07:05 AM »
Hi you all,
ive just converted my mill to cnc and tried starting to use it with mach3 and I dont have any prior experience with mach3.
So I want to tell you what happened:
The first thing ive done is, using a pcie db25 card, connected an leadshine MX3660 to my normal desktop pc (i7 4770k and R9 390, so nothing special) and installing Windows 7 32 bit on a seperate partition on it.
This worked perfectly well (as perfect as can be).
As thats my primary pc and I still want to use it while cncing, ive bought a secondary pc for the cnc (xeon 1220, Quadro 2000, ecc ram) and threw the 32bit windows 7 drive and the pcie db25 card in there. This also worked to the extend of being able to connect the MX3660, but when using them the problem started:
They not only whined unbearably but they also didnt really move as I wanted them to.
To illustrate this ive made this video of the issue:

I have also scoped the outputs of the motor driver, files in the attachment.
If it helpes I can also scope the parallel port while plugged in into both pcs.

So the question:
Does anyone how to solve the issue (exept for swapping out my main with my secondary pc)?
