I have a BL Touch. I set my start GCode to not probe a grid for every print to save time. But if I do remove the nozzle or the glass bed, I have to run the grid again and store settings, otherwise I’ll have issues on the first layer.
This can still happen with a touch probe as the probe-to-nozzle distance can change so the printer thinks it’s at the right height but that’s only based on the previous nozzle length.
