Copy firmware from one machine to another?

[greens83 5]

Hoping someone with more knowledge than me can tell me if something is possible. I have an ultimaker 2 which I upgraded to a UM2+ apart from the extruder stepper motor. I did this quite a few years ago. I vaguely remember having to alter the firmware to account for the stepper motor difference, steps per E I think. Anyway I have come into the possession of another UM2 and I have bought the same parts to upgrade (excluding a new stepper motor).

 

So I'm wondering If it is possible to copy the firmware from the modified UM2+ to the newly upgraded one? Is there a way to download firmware from a machine or copy it over to another?

It should be possible to dump the compiled hex file from the Arduino board, but it is complicated. There is no easy way to do it.

 

But you could install the Tinkergnome Firmware, then you can adjust steps, motor direction and a lot of other things directly from the printers menu.

@Smithy thanks for the info, I thought it must be possible but sounds more effort than just re tracing my steps with the altered firmware. Ill check out the tinkergnome firmware.
