Mach4 General Discussion / PMDX-422 help please
« on: June 17, 2020, 08:21:51 PM »
Hi All,

I purchased a basket case router that has a PMDX-422 Rev A1 and 3 4A drives for the steppers.

Nothing was connected to the machine so I decided to test the PMDX and drives before I started the rebuild.

I have a updated the PMDX and installed Mach4 Hobby demo version and the PMDX seems to be working.

I have a 24V psu connected to one drive and the moter connected to the drive.  The PMDX is USB powered.

My question is how do I connect the 4 inputs on the drive to 3 outputs on the PMDX and what should the 3 way jumper be set to +5V or GND and do I need to common the whole lot together somehow.

Thanks for your help, I am not daft just confused by new terminology.

Hi All,

I have made some LED buttons in Real Draw and exported them as PNG's with transparency, in Machscreen they look good with a clear background but when I load the screen into Mach3 I get a black background not the transparency.

Can you give me any idea what I may have done wrong.

Hi All,

is it possible to swap 2 images in a screen depending on a button press so one is shown if the button is on and a different one if the button is off and if so how can it be done?

Thanks for any help.
