Bibo dual 3d Printer / Cura 5.6

[xboxershorts 0]

I'm at a loss, I download my files from Cults 3D, I Slice my files in UltiMaker Cura 5.6.0

 

Print on BIBO printer.

 

Everything was fine and working properly, but now after I cut and try and print files, it heats the bed.

 

But the temp set for each extruder stays at zero.

 

The other files on my sd card still print and show the print temp where 0 is on. I seemed to have changed or modified some setting that is changing the slice to never heat and start the print.

 

Drink champ file 0/0 0/0 0/60 ( but the bed will heat to 60/60  and stay)

 

F150 file 22/200 ( heating) 23/0 37/60 ( bed heating) - good file printed x2

 

I do not think its a G code issue / possibly a filament setting... 

 

F150 file prints fine, its all files sliced post that file, but cant seem to find a setting isssue.

Tried to uninstall UltiMaker, but after I re install, it seems to just have saved all my settings. Cant figure out how to reset to a new printer, wont let me delete in Cura.

 

Running G-Code : Marlin , not sure if that matters

this is the file I am trying to print.

B2D_SAUROtrial5.gcode

SAURO.stl

when I manually heat and or load filament, everything works as advertised.

 

Its has to be when slicing the file.

There is a guide for completely resetting UltiMaker Cura to fresh install status 

 

Note: this deletes any settings or profiles you might have made

This is the first line in that Gcode file:

;FLAVOR:UltiGCode

Which I believe is UltiMaker specific.

 

This is from your printer definition file:

"machine_gcode_flavor": { "default_value": "RepRap (Marlin/Sprinter)" } 

that indicates you have the wrong Gcode flavor in the Machine Settings.  Unless you are absolutely positive that your machine is running Ultigcode you should change the setting to "Marlin".

 

There is a Cura bug that affects some dual extruder printers if the Tool Numbers are called out in the StartUp gcode.  You can try simplifying your startup and just allow Cura to handle the heating of the extruders and the bed.  I believe the bug has been addressed and should be fixed in 5.7.

If you use this as the StartUp Gcode it will eliminate the {initial_extruder_nr} which has the bug (it's always "0" regardless of which extruder starts a print):

;---StartUp Gcode

G21 ;metric values

G90 ;absolute positioning

M220 S100 ;reset the feed rate to 100%

M221 S100 ; reset the flow rate to 100%

M107 ;start with the fan off

G28 ; Auto-Home all axes

G1 Z2.0 F400 ;move the platform down 2mm

M117 BIBO printing...

;---End of StartUp

 

If you use that then the start of a gcode file will look like this (using Marlin as the gcode flavor):

T0
M140 S60
M105
M190 S60
M104 S200
M104 T1 S175
M105
M109 S200
M105
M109 T1 S175
M82 ;absolute extrusion mode

;---StartUp Gcode
G21 ;metric values

G90 ;absolute positioning

M220 S100 ;reset the feed rate to 100%

M221 S100 ; reset the flow rate to 100%

M107 ;start with the fan off

G28 ; Auto-Home all axes

G1 Z2.0 F400 ;move the platform down 2mm
G92 E0

M117 BIBO printing...

;---End of StartUp

G92 E0
G1 F1500 E-6.5

Thank you, Greg!  I was seeing this issue on Cura 5.6 and your start code fixed it.
