@dc42 Aha, perfect! Thanks! I always like to know and... understand, so to speak

@lb that makes sense - but I'm still not tracking on why a G28 shouldn't/can't be called from homeall.g?

Interesting... So substitute in a "G98 homez.g" and the like? I thought G28 Z (for example) just called the homez.g file?

I'm in the process of cleaning up my system files. I had been using the homeall.g generated by the config creation tool.

Question is, is there a good reason NOT to replace homeall.g with the G28 for X Y and Z and leave it at that? Assuming the homex/y/z.g files are all correct, this seems a much more modular/efficient approach.

Thoughts?

So, in short, the dimension constraints passed in M557 are relative to the probe? Not sure where an M208 factors in here?

Searching through, this seems to have been discussed before, but I'm not tracking on something.

I've got the following definition for my bltouch, mounted to the right of my nozzle:

M307 H3 A-1 C-1 D-1 ;Disable Heater 3. This is needed to free up the PWM channel for the BLTouch
M558 P9 H5 F750 T3500 ;Define a new probe type
G31 X36 Y-2 Z2.2 P25 ;Define the Location of the BLTouch relative to the nozzle
M557 X2:295 Y15:231 S35 ; Define mesh grid

My printable area is just under 300x230 and my BLTouch sits 36mm to the right of my nozzle.
I've defined M557 of X2:295 as X1 still contacts my limit switch. However, when running G29, I see;

Warning: Skipping grid point (2.0, 50.0) because Z probe cannot reach it
Warning: Skipping grid point (2.0, 85.0) because Z probe cannot reach it

Etc, on again for each time it attempts to probe X2. Now, the probe still actuates at those locations.

I think I understand that G31 defines the probe offset, so my question is whether M557's X/Y coordinate limits are defined relative to the NOZZLE or the PROBE?

Or if I've hosed something else up here, feel free to make me awares

Thanks!

I've attached the gcode file in question - and thank you so much for the quick feedback!!

Further fiddling this morning is pointing at user error (of some kind):

If I remove the bed/ext heat commands from my gcode file and manually pre-heat the bed and extruder, the print starts correctly and no Java errors.

Mistake in my tool definitions... or something?

I should add: this is a single nozzle/extruder printer and I have some suspicions my tool/fan lines are incorrect...

Appologies for the lack of config.g, attached below.
