ok my 3d printer nerd friends....

It should be
#define MOTHERBOARD BOARD_RAMPS_13_EFB

You tried changing it to some older variable name that doesn’t exist anymore. You weren’t supposed to copy the whole line and overwrite the old one. Just put BOARD_RAMPS_13_EFB in place of the motherboard name.

#ifndef MOTHERBOARD
#define MOTHERBOARD BOARD_ULTIMAKER
#endif

Take care to format it properly, G+ adds some wonkiness.

Got it…working…and ABL is working now… you the man…thanx dude… I’m new to this coding stuff…

OK, i hope your still getting my posts, well after i uploaded the FW and setup the ABL as per tom sanladerers vid, it works great when manually inputting the Gcode thru pronterface… however, even tho i added the G29 to the start code, it doesnt function properly… X and Y home then Z homes to the center of the bed… however it dosnt lower to the bed to probe it, it stays wherever the X carrage is in height and probes the air…then i get a Z endstop hit indication and everything freezes…ex… the X and Y home to 0, but the Z is at say 100mm above the bed…when it is told to home it moves to the center as it should, then moves up and down 10mm probing for the bed that is in fact 90mm below it… iv gone thru everything that i can think of to include removing the Z MAX endstop, and it didnt make any bit of difference…BUT if i manually enter the G28 and then G29 into pronterface it all works perfectly… thoughts? i also tried Cura and it did the same thing…so its not a software issue, i think its gcode or FW related…im wondering if it has something to do with the safe homing function?

on a side note, during heat up, the LCD says heating bed but not heating nozzle, where do i go to find the text and customize it the way i want? i found the text to display in the config.h file to say mendel ready…but cant find the others>…

I’d say post a new post, see if anyone has an idea. I won’t have time to look at it again for a few days

ok thanks…posted
