Solved Z axis moves but makes noise +video

I replaced my old ramps board after the heater bed wires shorted out and now my Z axis is making noise. All other axis will move normally but when I move the Z axis any direction, it will move as normal but then make a buzzing noise after stopping. I tried swapping the drivers and I still get the same result. I double checked the wiring and they all look like they are in the correct positions.



Im also now getting a "echo:cold extrusion Prevented" error now when I hit extrude or retract buttons.

I checked the jumpers and they are installed. I even swapped the ones from the old ramps board(just the z axis). All drivers are facing the correct way. I also tried connecting the z axis(one at a time) to the x axis and they would move one direction but no the other.

 

We have a winner! LOL. I adjusted the driver for Z axis and now it works, no buzzing, It moves smoothly. Now only other issue is the heated bed temp is reading high. It reads at 46 while the hot end reads at around 20. Assuming there is no issue with the bed or the wiring, im guessing there is a setting in the firmware to let it know im using a different heated bed? As far as the firmware knows, im using the R1 bed but now I have the R1+ bed.

 

Its probably ok then. I had to remove the bed and put it back in the printer several times while I was making the adjustments. Seems a bit higher then normal. While I was in there I installed the LCD screen and tested it. I ran out of time this week for testing but now all I have to do is glue the magnets to the new bed and start printing.

 

Its alive! First test print will be a cover for the LCD screen. Thanks for your help guys.
