Probe Signal active error after 2 successful probes
« on: April 20, 2018, 05:03:09 AM »
Additional to my probing interrupted error I have another strange isse.

I can run my Macro twice with just that "probing interrupted" error. At the third execution I get an additional error saying "Probing signal active!  Cannot continue."

Unfortunately this error message is not issued somwhere internal MACH4 and my macro doesn't get any feedback on that error and I cannot act appropriately.

As in the other Post - here is the log the macro generates (the mentioned error message is on line 92):
Code: [Select]
M1005 debug: initial check on probe contact: 0
M1005 debug: calculated StartHeight (-39) and StopHeight (-70)

Probing signal active!  Cannot continue.

As I am not changing anything between the execution of the macro I really don't understand where this error comes from.

Any idea is highly appreciated!

Sounds like a bouncy switch or a little EMI (noise).
;D If you could see the things I have in my head, you would be laughing too. ;D
