Ultimaker Original Firmware


Recommended Posts

Posted · Ultimaker Original Firmware



I have an Ultimaker Original. I've usually have used the bUltimaker builder for the firmware, but the site is having problems and since it's an older version of Marlin, I thought I would try compiling the firmware myself. I really appreciated the z-offset that was included in the bUltimaker firmware, so I tried finding something like it with the new one. Mesh Bed leveling was the best I could find, and I enabled it. However, I am having difficulty getting the nozzle to offset from the top limit switch like in the old firmware and the Z doesn't seem to be moving when I'm printing now through octoprint. The gcode on the sd card still has it squished, but it moves the z-height every layer like it should. I've looked around and I can't find too much on the subject or understand what I did wrong.


I have it homing at the bottom and all endstops are always enabled. Bed size is 210 x 210 x 205 (z is probably more like 202.5), custom made HB, and Reprap Full display.



Here is my starting g-code:

G21 ;metric values

G90 ;absolute positioning

M82 ;set extruder to absolute mode

M107 ;start with the fan off

G28 X0 Y0 ;move X/Y to min endstops

G28 Z0 ;move Z to min endstops

G1 Z2.5 F9000 ;move the platform down 2.5mm

M140 S{material_bed_temperature_layer_0} ;Start heating bed to temp

M109 S{material_print_temperature_layer_0} ;Start extruder heating and wait to reach material temp before proceeding

M190 S{material_bed_temperature_layer_0} ;Ensures bed heats to temp before proceeding if it hasn't already

G92 E0 ;zero the extruded length

G1 F200 E15 ;extrude 15 mm of feed stock

G1 Z5 F9000 ;move the platform down 5mm

G92 E0 ;zero the extruded length

G1 F200 E10 ;extrude 10 mm of feed stock

G1 Y50 F9000

;Put printing message on LCD screen

M117 Printing...


Here is the configuration file for the firmware. Had to put it as a zip.

      • 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.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
