I’ve tried slicing a calibration cube-thing, and the gcode that is generated is wrong in a few ways:
- Astroprint is adding gcode that I did not put in my starting gcode section for my printer (see comparisons below)
- The Cura online engine is not replacing the variables (or the curly braces are being replaced my Astroprint with question marks, and Cura has no idea what to do with those)
Comparison of starting gcode (preferences) and generated gcode:
Preferences:
G28 ; Home extruder
G1 Z15 F{Z_TRAVEL_SPEED}
M107 ; Turn off fan
G90 ; Absolute positioning
M82 ; Extruder in absolute mode
{IF_BED}M190 S{BED}
; Activate all used extruder
{IF_EXT0}M104 T0 S{TEMP0}
G92 E0 ; Reset extruder position
; Wait for all used extruders to reach temperature
{IF_EXT0}M109 T0 S{TEMP0}
Generated gcode:
;Generated with Cura_SteamEngine 10.09

So when I try printing this, the following happens:
- The hotend starts heating up, WHILE IT IS HOMED against my acrylic bed!!
- Once it has reached the 195°C, it re-homes
- It then moves 15mm away from the bed (Z+)
- It switches off my hotend and the print never starts (I have to reset my printer to be able to use it again)
So far, I’ve had no joy with my Astrobox, and that is a shame because I’m really looking forward to removing the 3 USB extension cords that I have running (on the ground) from my PC to my Printer.
