QTDragonHD - Versa Probe - Failed probe turns on Spindle was created by jimwhiting
So I'm running QTDragonHD linuxcnc-uspavve version 1:2.9.0.62.gef17bb8ead
When running a probe z if the probe fails the spindle ends up turning on. (I now have a physical inhibit on the VFD after breaking 2 sets of wires).
I'm not seeing anything in any logs about the spindle turning on, however the LED on the spindle start clockwise button turns on.
Any ideas as to what is happening... if the probe fails, does it skip some shutdown code?

I've tracked the LED on the QT Dragon turning on due to the M70/M72 use. Although that doesn't kick the spindle into running.

Looking into this soon. I will surely have more questions.
Can you explain how the spindle is controlled - an VFD it looks like. over serial port or using +-10 volt?

Hi,
Thanks in advance for looking at it!
Spindle is controlled over rs485. Using MB2HAL. I haven't managed to get it to do it again despite trying.
I had a macro from the QTDragon Facing/decking screen loaded as the program. I think somehow it kicked the cycle start state... I've not seen anything in the probing routines that would directly start the spindle.

I've been working through to try and figure it out... it looks like the probe_down(self) routine is not working for some reason. It errored out when I used it and then the spindle came on.
It completes the first search and the probe enables. It the doesn't do the raise?
(Which is odd as the probe block height, and the probe tool setter both do the same thing and work fine...)
Once it fails to do the raise, it will then not respond to any MDI commands. I have to click stop, then move it with the buttons on the screen. Only then I can enter MDI commands.[/code]

I am seeing the fwd spindle button change when g72 is called. I mostly understand the problem there but, I don't see how that turned on the spindle yet - none of the HAL pins change state.

I think I see how the spindle started.
Can you try this on you machine - don't put the probe in!
in MDI set:
S500 (or whatever safe speed)
M3 or M4
Stop the spindle with the screen 'stop spindle' button
now use probe down on the probe screen.
and immediately abort with the screen 'stop' key or keyboard escape key.
I think the spindle will be running now.

I am running QTDragon_HD and I think I ran into this issue while testing and trying to resolve an issue with my pendant. My spindle didn't actually start because I have a spindle lock that disables the spindle while using the probe.
I'll try your test and report back.

I ran the test and yes, the spindle turns on when I cancel the probe with the ESC key or it does not make contact withing the specified distance.
I'm really glad I was using a spindle lock with a disable feature.
