Deltaprinter "probe already triggered at start of probing move"

Poul Erik

Hi forum
I could need help diagnosing a problem with probing.
I am running Duetwifi and the IR probe.
The printer has been running without problems till now, but recently a problem accured.
The probe is working on the first couple of probing positions, but as it moves to a new position it skips the probing and continues to the next position. There is a error message when a probing point is skipped "probe already triggered at start of probing move".
Any help would be greatly appreciated.
Kind Regards

Please share your config.g and the results of M122 and M98 P"config.g".

Can you show a photo of the probe and the print bed?
Is there any consistency about the position that it fails?

@Poul-Erik Increase the 'H' parameter in the Z-probe definition until the problem is fixed.
Here's my mini-IR setup during bed leveling, but afterwards I can go as low as H3

I had had this problem on my setup. My question here is no really about this post but related to it: when this error appears, the gcode continues, so basically if you are not in front of the printer, the print will start anyways with having done the probe.
The question is: is it possible to add some verification so in case this error is reported, to stop the print/avoid the print to start?

@Phaedrux Thank yo for your reply.
I increased the "H" parameter in the Z-probe definition, as suggested by @o_lampe. This solved my problem.
Thank you again.
