How can I bypass this Klipper error? I cannot save my Z offset
Set z_offset in [bltouch] to 0.0 or more?
Are you trying to save a negative offset?
that's impossible
That would imply that your bltouch triggers after the nozzle has hit the bed, which of course wouldn't work.
z offset is always positive

z offset is always positive
So the problem is, it homes without a problem, but when print starts, it's too close to the bed, and I need to raise Z, which turns the Z offset into a negative value and I cannot save it. Instead of saving it, I put the SET_GCODE_OFFSET command in my custom start G-code but it did nothing. Right now I just need to eliminate the need to change offset manually at the start of every print.

Sounds like your printer.cfg might be slightly broken. Can you post it?
I'm thinking you have a z_offset: 0.0 in there while having the correct z_offset in the klipper config section at the very bottom. Klipper uses the last one (because of config merging) but sees the first one when applying the probe offset.
Because your z_offset surely isn't 0.0 or low enough that a minor adjustment puts it into the negative 🙂

I'll post the file as soon as I get home. But I can assure you that the I didn't touch the values, I only clicked on the Z offset buttons and tried to save, that's when the error popped up. In printer.cfg, the very bottom actually says a negative value.

That's impossible (it's not allowed)
I'll show you what's up when you post your printer.cfg, it's a bit confusing if you don't know how the internals work 🙂

Sure, thank you for your patience. This is my massive HevORT, with a huge bed and huge variance, thus the Z offset was needing quite a bit of adjustment

You're running RatOS on a HevORT?
vale elk
Yes. It's a shame that I still don't know how to make vanilla Klipper myself. The software and coding has always been my weak spot.
I run RatOS on everything, this HevORT, my CR-10 V3, which is about to be converted to a V-Cast 1.5 IDEX, and even my home decoration Neopixel strip runs on RatOS
