Unknown m code used: M190

Hi all,

We are battling a few issues after running an upgrade. We loaded an existing program which has cut no worries before the upgrade, but after the upgrade we get the error "Unknown m code used: M190" when we press the Run button. I repeat, this program ran without issues prior to the upgrade. What causes this ?

Cheers, Peter

Sorry Peter, this one fell through the cracks...

In your .ini file find the line:and change it to:
You will need to restart LinuxCNC for it to take effect.

Hi Phil,

Thank you, that works !

Do you know how we can get spotting to work, it used to worked flawlessly before the upgrade, but not anymore. Leaves us baffled. Sorry to be a pain.

Cheers, Peter

If you run LinuxCNC from a terminal do you get any errors on starting?

Can you explain what is happening?

Hi Phil,

It turns out that we needed to add a $2 after each M5 (for spotting). Funny that the same programs without that addition worked fine before the upgrade.

Thanks again for your help, much appreciated !

Cheers, Peter

Ahh, the spindle handling was recently changed in LinuxCNC itself. Now you need to use specific spindle numbers. It is a change for the better and a bit safer I feel.

It's true that it's better and safer, just a bit of a bugger we were not aware of it. And we have to modify the post processor to suit the change. And it means we have to edit all our existing programs that need this change. That might give the boys in the workshop a few headaches in the near future. Oops.

There was a bit of discussion about it on the developers mailing list. It is probably worthwhile subscribing to it and then you can keep an eye on any changes to see if the will affect you.

All Plasmac changes are announced on the forum as well so you should subscribe to that as well.
