3.5.1 M226 flaky or user error?

airscapes

Hi, trying to put an M226 within my Gcode to stop a print to insert a washer. This works hit or miss. If I place it at the start of a layer, it will work. If I take too long to put the washer in, once resume is hit, it will move back, sit there and present an error that it took too long. When I tried to add this in a different area (before infill) it will return to the stopping spot
and home z and just be unresponsive. I did a search and have seen post about similar behavior in older FW versions but nothing resent.

I would like this pause in the infilll rather than the perimeter if it will work that way but I have a feeling you are going to tell me that is why it is not working

@airscapes Because M226 calls pause.g and resume.g (when you resume), can you post those macros?

Also, if you're on RRF 3.5.1, it may be worth updating to 3.5.2, as I think there were some bug fixes around running macros during a print.

@droftarts Thanks! There is also some weirdness with Y homing when loading a Hight map, so maybe the upgrade will take care of that as well.
Here are the 2 macros.. The pause and resume using the GUI works as expected and if I add the M226 at the start of the layer is is also working correctly for the most part.
