GCode Header
| Contents | 
At Hyrel, we believe that you must start with a good GCode header to get a good print. Below are explanations of our standard header files. These can be configured in Slic3r under Printer Settings > Custom G-code > Start G-code
Sample Header
- BLACK entries are for every machine
- GREEN entries are recommended, but must be manually entered
- RED entries are for the EHR only, and MUST be edited by hand
- BLUE entries are for the 16A only, and MUST be edited by hand
- PURPLE entries are explanations
- GOLD entries are optional, but recommended
This is what your header recipe will look like in Slic3r:
; REPORTING/ABORTING :
N14                ; set line numbers for error logging - Slic3r version
M772 S1            ; reset metrics and arm automatic reporting 
M627 X0 Y0 Z0 J-500 K5                 ; setup abort action
; 16A PREHEAT TO SAVE ~ 30 SECONDS ON 16A :
M140 S# ; where # is ~15 degrees below print temperature - to start heating 16A bed sooner
; RANGE SETUP
M107               ; fans/UV           ; off
M106 C255          ; fans/UV           ; set to 0-255 range
; OFFSETS and POSITIONING
G53                ; clear offsets
G21                ; units             : mm
G91                ; coordinatess      : relative
G0 Z10 	           ; drop bed 
G90                ; coordinates       : absolute
G28 X0 Y0          ; home, goto        : X and Y
M229 E1 D1         ; enable E-values (volumetric) - best when slicing for filaments
M660 H# Z#         ; sets Z offset on EHR
G0 X0 Y0 H#        ; applies Z offset on EHR
; HEAD DESIGNATION :
T2                 ; use THIRD tool position from the left 
; TEMPERATURE CONTROL :
M190 S[bed_temperature]          ; bed temp     : set and wait
M109 T12 S[temperature]        ; head temp    : set and wait
