plasmac spotting broken

So why after a rebuild does spotting not work, it just sails past without a probe.See attached gcode

I have had the same issues as well but have been to busy to ask Phil about it.

Not sure I ever saw your config stuffs, I know you redid a lot of it recently, just thought I'd make sure you have multitool enabled...

setp plasmac.multi-tool 1

Man, I don't even want to look at my config! Thanks though, I'll check it out tomorrow.

I will be interested to see if Rod and Stefan report back that multi-tool caused their issue, this thread jogged my memory of these changes made to the LinuxCNC multispindle code following issue #713

The multi-tool pin was devised as a workaround to the fact that when multiple spindles were introduced the M3 and M5 commands without a $n operated on all spindles at once. The above changes make it so that M3 and M5 commands without a $n now operates only on spindle_0. This makes it compatible with all previous G-Code. I now think the multi-tool pin could be made redundant and mutliple tools should always be available.

How did you make out with the pin? Were either of you able to get spotting working again?

I’ll guess no news is good news, and that was the problem..... ¯\_(ツ)_/¯

Took the time to simulate this, since following up on "issues" helps others out when they encounter similar blunders. It's helpful to definitively discern between "PlasmaC is broken" and "User Error".

I have confirmed that without the following line the torch just "sails past without a probe" as @rodw whinged about:


It's nearly impossible to see if the "Torch On" led lights up since it happens so fast, but with the help of Hal Scope, I was able to confirm that all is well:

Thanks Greg, that was indeed the problem. I had it set to 0.
I am not sure if Plasmac did that on the rebuild or not.
To me it does not make sense to be able to disable the multi tool features in the first place and the config default should be enabled.

Unsure what the default is, my understanding was it defaulted to off, and the line wasn’t present in the hal file.

At any rate it’s probably going to change now that they handle multi spindles differently anyhow. Think Phill was awaiting your confirmation that changing a 0 to a 1 solved the issue before making any changes.
