Ultimaker 3 extended default steps/mm on x/y motor


Recommended Posts

Posted · Ultimaker 3 extended default steps/mm on x/y motor

I recently got an Ultimaker 3 second hand. Was pretty happy about it until I got home (was pretty cheap) and had the time to test it.

Prints aren't dimensionally accuratem they're off by 10mm and also it misses steps (layers from some point just slide to one side).
From my know how with previous printers it can be the pulleys, belt, motor or steps/mm.
In my config file they are 80mm/sec is this correct? If you are there mind telling me the default print steps for all motor and also the motor amperage since i've had some overheating & skipped steps? 
These are the values you are looking for: in my current version i could find them in: /usr/share/griffin/griffin/machines/um3.json
  • default_steps_per_mm (all motors please)
  • default_motor_current (same, all axes please)


Thanks in advance and also thank you to all members contributing, I've been lurking here and gathering know how

      • 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
