Hi folks,

in the past days i updated my trusty D-Bot to the latest RFF release and tried some meta commands.
I came up with a first layer calibration script (simliar to Prusa Mini) someone might like (and dares to try).
It should work on most cartesian printers.

The script consists of 2 files:
The macro that starts the calibration script (place it in 0:/macros/) and the actual calibration script itself (place it in 0:/sys/)

There are several config parameters which should be rather self explanatory.

I'm looking for further improvements and things I might have missed or misunderstood.

0:/macros/First Layer Assistent

; First Layer Assistent v0.1
; This is a First Layer Calibration Script "kinda" based on the Prusa MINI
; Developed and tested on a D-Bot (Core XY) running RRF 3.4
; Macro starts a Printjob so Babysteps can be adjusted
;--------------------------------------------------------------------------------

; Make sure we are not currently printing!
if state.status != "processing" && state.status != "paused"		
	; Continue

; What it does:
; 1. Reset trigger height (& mesh / optional)
; 2. Preheat to leveling temp (170C / Ooz prevention / optional)
; 3. Home
; 4. Mesh bed leveling (optional)
; 5. Preheat to material temp (preset to 220C)
; 6. Purgeline
; 7. Adjust Z-Offset using Babysteps while printing line and infill patterns
; 8. Save new Z-Offset and reset Babysteps
