I bought a K8200 which is already extensively modified by the previous owner.
It runs well, I’m currently trying and tweaking with the settings to see the difference in results.
I would like to program it with new firmware too, but I cannot see which version is already installed (they all read V1).
Is there a way to backup the firmware that is presently on the board, not needing an ISP tool?
It’s always handy to have a good functioning backup.
Yes I noticed it was quite fiddly…, the arduino environment seems to be made for PC to controller only.
I currently do not see the EEProm option in repetier host 1.0.6. Ik think that is because in the software you need to define an EEProm line first. I do not know is the previous owner has done so, but offcourse I want that so settings can be changed in EEprom.
Therefore, I want to try the new V2.1.1 firmware, to enable the EEProm line to see is that also enables repetier EEprom settings, and to have a general better understanding of the printer’s firmware.
But I also want the backup of the current firmware, because I do not quite trust myself to get this first-time right, and can restore the firmware to present state if I make a mistake.
(I was thinking maybe it is easier to get the atmel IDE, and an ISP programmer.)

Might be, but i think that is overkill.
There are only 2 (and a half) firmware versions out there.
The V2.2.1 is basically 2.0 just with an edites steps/mm seting for the z axis. (because it’s made for the K8204 upgrade.
So if you try that version, remember to set the corrext Z steps/mm if you don’t have the leadscrew mounted.
Any other should be just the same.
Flased it with my modified 2.1.1 version, using the standard procedure on http://www.K8200.eu.
Modified because I have the bulldog extruder, E3D V5 hotend, and 0.9deg/step X and Y motor some step sizes are different (K8404 upgrade was already in the firmware offcourse, my printer has dual motor Z axis with dual K8404).
Made sense to put it in the firmware by default. Also enabled EEPROM chitchat.
And now I can read EEPROM data in repetier. Happy with that!
