what this error mean ?

[jay_s_uk]

@paboman reprobe the bed height (i.e. home it) before loading the heightmap

I cant reprobe the bed it as i dont have the probe anymore.

it was working until today....does the heightmap have an expiration date ??

[jay_s_uk]

@paboman no, it doesn't. how do you home the bed?

its a delta, I home the printhead with G28

@paboman thats one massive delta.
when are you loading the heightmap?

yes, and its 4 year old now. worked good until now.

I load the heightmap in the Homedelta.g

@paboman I don't see any issues there.
You could try adding an M561 before the first G91
Have you made any changes like update the firmware or anything?

I am running on Firmware: 2.05.1 - Web Interface:1.21.1

@paboman on my deltas with smart effector I need to home the effector then run G30 to establish the Z0 datum, and after i have the G29 S1 to load the mesh
