Please add option to continue in spite of "risk of nozzle crash"

[Steven_Hines]

I have a commercially produced PCB (based on a design I printed on my Voltera) that I want to print solder paste on to mount components.

But I’m currently blocked because of the “helpful” software warning me that one point at “1689um” is dangerously lower than anoither point about 15mm away at “1711um”.

The board is clamped to the voltera as hard as it can be and the board is completely flat. I honestly can’t understand what the danger is or why the tip can’t move up/down 22um over a distance of 15mm to avoid it.

As it happens, I don’t even intend to put paste in either one of these places. So I just want to continue. But the software blocks me permanently until I fix the problem, and AFAIK there’s no way for me to equalize the heights here.

Maybe just let people go forward at their own risk?

FYI, I found a work around for this problem.

In my case, on the board prior to the probing step beginning i had one probe point with two blue circles around it (see screen grab below). After the probing step completed with an error, this point had two measurements associated with it: one correct and one at zero. It’s the zero that was causing the warning and preventing me from continuing.

I fixed this by downgrading the app to version 3.3.1. Re-using the alignment from version 3.5.0 works perfectly and the probe step passes without error.

@Steven_Hines I’m not sure if this would help in your particular situation and it sounds like this may be a recent bug, but have you tried increasing the maximum height difference setting in Settings > Beta to see if that’s another possible workaround?

Thanks for the suggestion, but unfortunately it’s a bug in the new probing system that’s preventing me from making progress. The only apparent solution so far is to downgrade to version 3.3.1.
