G-code start?
Posted: Fri Apr 24, 2015 12:34 pm
Hi guys, I want to try Cura but it seems that it doesn't handle temperatures like Slic3r.
"CuraEngine does not handle temperatures. You need to set them in the “G-Codes” tab." http://www.repetier.com/documentation/r ... t/slicing/
So I downloaded a g-code from another user and open it. Can someone explain to me why this g-code is so large?
The start G-code for Cura:
G28 ; Home extruder
M107 ; Turn off fan (the fan wired to mosfet FAN 0?, layer fan?, and why turn off?)
G90 ; Absolute positioning (what's that?)
M82 ; Extruder in absolute mode (?)
{IF_EXT0}M104 S{TEMP0} ; EXTRUDER TEMP (OK, turns extruder on with no wait)
{IF_BED}M190 S{BED} ; BED TEMP (OK, waits for BED temperature to be reached)
{IF_EXT0}M109 S{TEMP0} ; EXTRUDER TEMP (OK, waits for EXTRUDER temperature to be reached)
G28 ; Home extruder
M117 HEATING ELEMENTS (?)
; BEGINNING OF HEAD MOVEMENT WARNING TONES
M120 S4 P10
G4 P40
M120 S4 P10
G4 P40
M120 S4 P10
G4 P40
M120 S4 P10
G4 P40
M120 S4 P10
G4 P40
M117 KEEP HANDS AWAY
G4 S3
; END OF HEAD WARNING TONES
My start G-code for Slic3r:
G28 ; Home extruder
G1 Z300 F3000
What I would do:
G28
{IF_EXT0}M104 S{TEMP0}
{IF_BED}M190 S{BED}
{IF_EXT0}M109 S{TEMP0}
G1 Z300 F3000
Is everything else really necessary? What are the "warning tones" in the end?
Any help would be greatly appreciated.
