Thanks. I have found the NAN issue, it is due to the sender expecting tool offset values for all axes in the TLO report. grblHAL and some other ports outputs...

Fix for NaN issue added in [latest release](https://github.com/terjeio/Grbl-GCode-Sender/releases/tag/v023-beta3). As for the how probing is implemented a good starting point would be to add a wiki page as a reference/specification and...

For most of the grblHAL drivers this is not an issue as I use a 32 bit timer whenever possible. In fact I have had to limit the [maximum step...

If I have done it correctly this is fixed in 2.0.36, I need to retest after moving some code for the XL version.

It is supported by the iMXRT1062 driver, perhaps a few more. It is implemented by [repurposing the reset input](https://github.com/grblHAL/iMXRT1062/blob/97cf1e012251fb6478bdba9f3ed6f8805075f9f9/grblHAL_Teensy4/src/driver.c#L1009-L1034). Search for `ESTOP_ENABLE` to see the rest of the implementation details....
