Updating Firmware old machine?


Recommended Posts

Posted · Updating Firmware old machine?

I'm looking to update the firmware of an older ultimaker I have.. I think it has the 2560 atmega installed.

when I look at cura it says I cant as it it doesn't support my config (heated bed)

and also warns that I must have the extruder upgrade.

Is the extruder upgrade warning, just due to the different e-steps with the newer V3 bolt? or something else.

So i'm looking to use http://marlinbuilder.robotfuzz.com/ and construct the custom hex. would this be ok on an older machine, if I just change the esteps, until my new V3 bolt arrives?

Thanks for a stunning forum btw ;-)

    The E-steps in the firmware don't really matter if you set them in Cura machine settings. Those will override any value in the firmware, and the firmware from marlinbuilder should work just fine with your machine.

    You should be fine. Do you have the old hex file in case you want to go back to an older version again?

    robotfuzz works quite well. yes I suspect the only thing is the steps/mm for extruder. So you can calibrate that and set it to whatever you want.
