    All you had to do was edit the one line in the firmware you had.

    I reinstalled the 5/16" firmware because that was letting me jog up and down no matter how far. I then changed the line you gave me. The jogging problem came back. Just wanted to eliminate firmware as an issue.


    OK let me add a little more to this problem or perhaps eliminate

    I removed my 8mm rods and did some jogging up and down and I can job 10mm and 100mm with no issues. Guess that means my issue is mechanical and not electrical?

    I removed the x axis from the z axis and was able to jog up and down 1,10,100mm with no issues. As soon as I put the x axis back on the binding starts again.

    Ok did a bit of digging and now I think I've gotten rid of the binding. I lowered the z axis as low as I could using 1mm jogs. I then tilted the printer on it's side giving me access to the ramps board and the stepper drivers. I then sent the z axis up 100mm and turned up the z axis pot still it studdered, then backed it down just a bit. Did it a few times to get a nice setting.

    Now I can go back to working on the bed heating issue.

    Ok i tried running the same part in MatterControl and after the first 2 layers printed the temp started climbing again. I cancelled the print job when the hot bed temp reached 70 degrees.

    Ok I think i've resolved my issue with the heated bed heating up during a print. I was putting google through it's paces and looking in every nook and cranny of the internet and I found a post on the reprap forums about someone having a similar issue with another brand of 3d printer.

    The metal part of the MOSFETs on his ramps board were touching. I quickly flipped up the Robo and found that two of mine were touching as well.. I grabbed a pair of needle nose pliers and ever so gently straightened them up and ran another test print.

    Over half way through the print and temp is holding steady at 60 degrees.....
