Yep , that was it. Had no idea there would be a new macro folder.

Thanks

Now just to dial in this VFD . Just out of curiousity , what other devices are avail to control a 30hp spindle motor besides the vfd?

looking at the serial modbus setup page the setting all seem to be the same , between the pp and ss configurations , I am wondering if there is a check box somewhere I have overlooked

thanks Hood, i did hook the Parallel port back up and everything is running fine. I did create a new profile for the SS . Do the serial modbus settings need to be reconfigured for the new profile?

Is there a simple setting that will allow me to once again have mach communicate with the PLC after the install of the SS board?

Well I said everything was working properly but I cant get the VFD dialed in or anywhere close to the rpm called out. I can adjust the pulse lenght and get it to turn at the speed called out in one range but then its off by as much as 50% just 100 rpm either side of where its tuned.
I have been using the vfd to control the spindle motor for about a year and had it dialed in within 10rpm of the speed called out across the entire range , from 50 rpm thru 1700 rpm . How or why has the instalation of the ss and drivers caused problems with the output to my vfd?

My apologies for posting a SS related question in the general forum but I was afraid with the limited traffic in the SS forum my post there might get overlooked and I need to turn a bunch of parts tommorow.

I installed a smooth stepper board yesterday and have almost everything up and working nicely, but since the instal Mach will no longer communicate wuth the PLC that operates my tool changer . What do I need to look at or change to get Mach to communicate with the PLC?

OK , got the vfd dialed in by adjusting the po=ulse width on the SS setup page.

I got the spindle encoder working properly by playing with the debounce for inputs.

How do I get the computer to communicate with my PLC again via modbus? It was working perfectly before installing the  smooth stepper and related drivers
