USBBOB is capable of all of those functions on the lower panel with the exception of the potentiometers for the spindle speed and feedrate overrides. You'll have to replace those pots with the included encoders to control those functions.

You may or may not have to replace the handwheel depending ...

To be clear, to address the target file "acorn_mill_plc.src", you must have the current working directory of the command prompt set to the same directory as said target file.

Marc's directions have you first move the current working directory to cncm which contains both, hence the lack of full ...

Thanks for the info, that’s encouraging that most of the controls will work. Are you saying the usb bob has encoders i can swap for those pots?
Also, where can i find literature on the plc programing changes? Thanks

It looks like we have two documents on setting up velocity mode or position mode with Sigma II drives.

Do you know if the drives are currently set up for position or velocity mode?

Regardless, see technical bulletins #108 and #295 for some parameter settings. I would confirm what the settings on ...
