UM2 UltiGCode "activation"

Recommended Posts

Posted · UM2 UltiGCode "activation"

Before I start browsing the code again, does anybody know what *exactly* is

required to make an UM2 start and operate in UltiGCode mode?

A starting sequence of


;FLAVOR:UltiGCodeM107G1 X46.152 Y48.191 Z0.2 F6600G1 X48.191 Y46.152 E0.0398 F1500...


(Lol, looks like the syntax highlighting doesn't like G-Code :-)

is obviously not sufficient.

Upon start, the machine indeed does not shows its "manual override warning" (RepRap)

message and then starts as usual, homing all axes, moving to X0 Y0, but then, it immediately

starts _without_ heating the nozzle and immediately begins with cold extrudes...

So, what else is required?

The time or material info?




The layer markers?


;Layer count: 98;LAYER:0...


The Cura profile string at the end?




I'm especially confused about the missing heat-up of the nozzle.

So, I obvisously found an in-between mode, which didn't completely activate

the UM2 mode...

    Yep, found it, thanks!

    If "MATERIAL" is missing in the G-Code file, the target temperature is

    not initialized and the comparison with the measured value is always true.
