Probing skipped when work origin has negative offset

[mmwaves]

Hello,
I needed to machine longer piece, so I tried to do it in stages, moving the stock. When I set my Work Origin with -148.5mm Y offset from Anchor1, Scan Margin and Z probing is skipped and machine proceeds to change tool to the first one in the code.
I've tried to manually set the position and initiate Z probing, but it just does nothing when I click Do ZProbe.
This issue occurs on both 1.0.5 and 1.0.6 firmware. The controller version is 0.9.14.

I tested according to your procedure, and the phenomenon you reported did not occur. The machine will report 'Soft Limit Triggered'. Additionally, x offset / y offset should be set to positive numbers.

Maybe You tried with smaller stock (I used 300mm long stock). I did some further testing, and it seems that the issue is not with the negative offset itself. With this high offset and long stock, the working area is about in the middle of the table, but the Y coordinate is then larger than 230mm. I think there is some kind of bug that it does not take into account the offset and just skips probing when Y position is larger than the size of the table in the machine. Please note that this only affects probing, because machine proceeds to milling in the right spot. It can be worked around in the CAM software, but it is a bit annoying.
This can also be bad when user expects the first tool change to be to the probe and will not notice that it calls for different tool - it can potentially damage the probe.
