Can some explain to me like I'm 5 years old why my z-offset / first layer is different every time?
I'm not a total noob, and this has baffled me for ages. I get great , repeatable results with my janky old creality, but for some reason, and yes, I know it's me and I am doing it wrong. I just can't get a consistent start on my ratrig v4 500 hybrid. If I can get the print to start at the correct height, the machine is running great, I get great prints.
--I've done beacon calibrate several times. Took me a while to figure out the process, but i get this, consider this done.
--The machine is doing a beacon scan (not contact) before each print and seems to be using that height map to compensate for the bed, This is working
The problem is that the machine seems to have a different z-offset for each print start? I have to make wild adjustments during my skirt printing to get it right. It's always too high, so that's been nice. No gougeing or rubbing.
Please tell me like I'm 5 what the process is to get a consistent start every time?
I know to re-evaluate/calibrate after nozzle changes and other mechanical changes

The beacon should be using the contact mode to find Z=0. The contact mode has the nozzle physically touch the bed. If there is stuck filament on the nozzle it can though off the z offset. Make sure it’s clean.

thanks. is this the line of code for that? again, I'm like a 5 yo in this situation
variable_beacon_contact_z_homing: True
it was set to false
I would need to check the documentation
@clutchmasterx1 thanks, I think this did it. I've just now had 3 calibration prints in a row start at the same height. And I've added some extra awareness and a little manual nozzle wipe before each start.
