Hi all
Another newbie here. . . just taking my 1st steps into CNC with a small desktop mill. I have my first question I hope someone can help me with.
I have the machine set up, running under jog control, and soft limits set.
I have a problem with the Feed Rate Over Ride preventing the machine from feeding at the set federate.
The g-code has a federate of 300mm/min. The program runs fine when not attached to the machine. But when ever the machine is attached to the PC I get the red LED for Feed Rate Over Ride come on and it down regulates the feed so something ridiculously low. If I click reset it jumps up momentarily but then gets overridden. It does the same even if there’s no toolpath loaded – as soon as it’s connected to the PC.
I can’t find anyway to turn off the feed rate override. (It’s a demo / trial version of Mach 3 currently while I learn my way around).
Any suggestions where I go look for settings that may cause this please?

Sounds to me like you have a Brain or the macropump or possibly even a hotkey acting on the feed override down button.

Hi Hood.
Thanks for taking the time to reply.
I've had a browse through the various config' screens but could not see anything obvious that might be causing the override. I confess I dion't really know what I'm looking for however. Searching the user manual didn't help too much either.
Can you give me a bit more info on where and what to look for please?
Also - do you think I may better off just downloading a full purchased license and re-installing? I will need a full icense long term so will probably have to do this anyway.
Any pointers very much appreciated, I'm very keen to learn.

If you attach your xml I will have a look through that to see if there is any config issues in it.
