I have software limits enabled and speed is reduced when approaching the Soft Max limit. When approaching the Soft Min limit which is 0 the jog speed isn't reduced. Slow zone is set to 1.0. Does the speed reduction only apply to the Soft Max limit not the Soft Min limit? Or is this an issue with the MPG and its plugin? It is a Homann Designs MP01.

Works fine for me here but I use the SmoothStepper with MPG direct to it.
Does the speed reduce when you use the Jog keys rather than MPG?

You know the problem didn't appear until other people started operating the CNC. When you put it together yourself you are just more careful. It turns out that you could crank out the MPG and slam the proximity sensor into the hard limits. I never considered this or why would you do this but to prevent it from happening again adjusted slow zone to 3.0 inches and now it won't happen unless the software limits are disabled. Do you know of a way to remove the software limits On/Off button or just lock them ON.

You would have to edit the screen, with one of the screen editor programmes, to remove the button.

Thank you, Hood. I haven't worked with a screen editor yet so this gives me a reason to try it out.

If other people are using the CNC it would actually be quite amusing to change the softlimits button to a VB button then put a wee bit of VB in it so when they press it a message pops on the screen asking why they pressed it when they were specifically told no to. :D

Now thats an even better idea. We definitely both have the same sense of humour!!
