Probe basic error exceeding axis negative value during calibration

I am reclaibrating my probe due to issues I was having in a separate thread, this time using a gauge block. Previously I calibrated it using a 5mm gauge ring and the calibration cycle worked fine. However, every time I try to calibrate on this gauge block I get an error saying I am exceeding either X or Y's negative limit and I can't seem to figure out why this is happening. I am not anywhere close to my axis travel limits. I am attaching pictures of my tool and probe settings. They seem fine to me? I have tried varying the stepoff and nothing changes it. It seems like there is an offset / ini issue that is colliding with the way the probe cal works but I can't figure it out. I currently have my X min limit set to -8 but I tried adjusting it to -16 and I am still getting the same error.  


The picture shows a step off of 20 but I tried reducing it all the way down to 6 incase my min axis values of 16 were somehow messing with it and it did not fix the issue

EDIT I just realized..even if I go back to my old probe_cal value and try to probe a boss, I am getting the axis limit issues as well so it seems like something strange has happened

I was able to do probe calibration by significantly increasing my axis min/max values for X and Y

However, this doesn't solve the issue as I cannot do any regular probing of parts anywhere on my travels without these artificially increased values. Does anyone have any ideas on what offsets might be causing this? My probing was working previously.

Solved: MAX X/Y value of 110 was too high for my small machine.

Are you using a centered home position with + and - in each axis?

Read the probe help yeah to understand all of they parameters.
