Thanks JT

It was the firmware I was unsure of, the only one I have seen for the 126 only had the single set of inputs & outputs

Hi Racedirector

I have my PMDX running on a std parallel port sort of I could not get the power working from LCNC to turn on the machine there needed to be a different line put into the hal file. CNCbasher has been very helpful with this all, I hate to keep annoying her but I am just about over this hump. The machine moves everywhere with the keyboard and also the GUI. I was having homing issues but seem to have that sorted now but I have a real weirdo at the moment. The machine will ref now on Z and X but will not move the Y axis at all when I use the ref all button. Yet I can control the Y axis with all the other controls. Have you seen this?. I thought maybe a computer issue so I have another clean PC here I setup with a fresh version of LCNC and just put my INI and HAL files into it and it does exactly the same thing. Yet I can not find anything missing in those files.

The line of code that got the machine power working is here

net motion-enabled charge-pump.enable motion.motion-enabled

net estop-out charge-pump.enable iocontrol.o.user-enable-on this is the line that got replaced and then the Estop and power buttons worked fine on axis

I used the machine power circuit from PMDX its the first one on the page

Once I get this last issue sorted with the Y axis doing ref to home it will be ready to use.

The next step is to replave the internal parallel port with the 5I25 mesa I have here. I will probably run it as a parallel port out at first then look at installing the 7I76 a little later. I want to get used to the LCNC software first.


If any of the mesa gurus here are reading this will I actually notice any difference by going from the std parallel port built on the motherboard to the 5I25 configured as a parallel port?

I have attached my 2 main files so if anyone else is having the same issues this may help them along

Anyone who may have seen this ref home issue it would be nice for any advice please
