Rambo Servo Setup for Auto Bed Leveling for Noobs

[walkercreations]

Thanks everyone for the replies. It is very much appreciated. I'm at work on an overtime day so will have to try the whole numbers bit this afternoon. If that doesn't work, I will upload my SanityCheck.h to see if that is any help.

I ran into this trouble as well... it will fix it :-)

The whole numbers thing did work. Now I don't understand how this is supposed to work. When setting it up, I told the Rambo the Zero point was where I made the mark on my Heated Bed. I made the mark near the center of my Bed and followed the procedure like Michael's video's instructed. After I did all that I home all the axis. The X and Y Axis go to their End Stop positions and the Extruder goes to the Back Right Corner where the original Home Position was before installing Bed Leveling. I enter G29 to go into the Bed Leveling Routine and the Probe only comes down at the Home Position and that's it. In Pronterface it tells me the Auto Bed Leveling has been done and gives me some coordinates. I get a message on my LCD saying "endstops hit: Z" and that is it. It is supposed to do the Grid pattern as I have it set it up. Any ideas what I may have missed or done wrong? I homed everything and did another G92 X0 Y0 Z0 and still no luck. I'm at a loss.

Any help or information is greatly appreciated.

I think my printer has become possessed...!!

ABL was working perfectly 2 days ago...i turn it on today for the first time since and..the G28 and G29 commands make the z carriage move up instead of towards the bed..BUT...if i press the negative Z in Simplify3D controller it moves in the correct direction. So ,that means the wires are not inverted nor is the direction of the steppers in Marlin. Ive reloaded Marlin several times from a fresh download and NADA!

What can it be???


Sorry for the double post it the Itty Bitty Flex Thread..
