Feature Workflow

i find this one https://github.com/rpavlik/Marlin/tree/mightyboard-twox complation is ok and marlin standing is ok with pronterface lcd is not working , and hotend is not heating

Additional Information

May be its so little space of memory but i thinking it will better than sailfish firmware : can t adjust step and velocity or many thing can be marlin if someone have this printer , could test this link ? thank you

I tried the above Marlin. The same problems. No any pronterface input until I press reset button on board. Then I see M503 output on monitor. But no any reaction on input commands. No Ok's But pronterface stays connected.

I found this https://www.reddit.com/r/makerbot/comments/g99ppr/anybody_want_to_help_with_a_replicator_22x_marlin/

https://github.com/rpavlik/Marlin/blob/mightyboard-twox/Marlin/src/pins/mega/pins_MIGHTYBOARD_REVG.h

main thing stopping this is there is no support in standard marlin for ADS1118 ADC, used for Thermocouples

also All Mightboards after rev E are closed source. So no schematics, very little available information on the net about them.

Regarding the ADS1118 - it looks like there's some sample code, and with a quick look, a workable(?) driver here : https://github.com/ReclaimerLabs/ReclaimerLabs_ADS1118

What's preventing support for the ASS1118? ( I may volunteer adding it, but want to understand what I am getting into since I know nothing about the Marlin source code !).

Regarding the board itself, I have a note out to a repair shop that regularly repairs the MightyBoard -- if there's a stream of valuable software that keeps it running, it keeps their businesses going -- so I have asked if they have a schematic.

Barring the schematic, I can easily get photos of the Gen H board. Is this helpful in any way ?

Thanks!
