Like any other Ultimaker printer the UM3 can read text files with the file extension ".gcode"
In addition the UM3 is able to directly use gcode files that are compressed with gzip, those will have the file extension ".gcode.gz". Cura generates such files by default if you print over network, but it's not mandatory
But: the .gcode file has to begin with the mandatory Griffin-"Header" - basically a few lines with specific comments that describe the print job.
The easiest way to get such a header is to prepare a similar print job in Cura, slice and save the gcode file to disk.
Obviously you don't want to heat anything up - so set all temperatures to zero.
Take a look at the header lines in the file, it's not very hard to interpret. Afterwards replace everything below the header lines with your own G-Code commands.
Further:
I'm not sure, if the UM3 supports the G28 command (i think it does not?) - it's possible that it will be ignored or it will work different from what you expect. The UM3 has its own start- and end- procedures builtin that are performed for every print. There's no easy way around it.
You should add a feedrate (parameter "F") prior or within the first move commands, to tell the printer how fast it should move.
Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
