Yes, thats their config, im in the process of tunning my stepper drivers to see if that makes a difference. Im having plenty of trouble just trying to that. And are you saying that you didnt have to do any firmware modifications really?Quote

Is that the config that came from Folger? I finished mine a few weeks ago, and it came right up on thier config, with no need to change much of anything, and using thier procedures.

IIRC, I set the specifics for rod length, and the Z axis max, and was able to print. All the pertinent settings are already in the Folger downloads.
Never had a bit of an issue setting driver current either. Meter probe from the end pin on the driverto the leftof the pot to the pot wiper,twist, good to go (and about that quick). My only problem was that the Chinese knockoff Molex power connector burned after a couple of hours, and I had to replace it.

For some reason the issue still applies. My Z axis is the only axis that moves. I redid my wiring to make sure it was all neat and correct, reuploaded the firmware, and triple checked my drivers and even switched them around to make sure they were functional. Yet some problem);

Does the extruder move? If so, swap the drivers for E and Z with X and Y, and see if the problem follows. If so, the it's software or a problem in the Arduino or Ramps. If it moves, then it's the drivers. Have you been able to read the motor current settings yet? This is a passive setting that doesn't even require 12V power to the RAMPS, if I recall correctly. About the only thing needed to read that is a DC voltmeter set onthe 2V scale . . . .
And, at the risk of asking a stupid question, when you downloaded from Folger, you did get the downloads for the Kossel and not the Prusa, correct?

I did download the kossel 32 tooth. When testing the drivers I had to use the right top pin instead of the left, becaue the left for some reason wouldnt read out to me. Ill try swapping out all my drivers with the ones off my prusa i3 and see if that works. I'll let you know

It sounds like either bad IO on the Arduino, or somehow your pins.h file got knackered, and the drive signal is not getting to the right pins. I suppose a defective RAMPS with some bad traces could do this as well, but to hit two separate functions the same is unlikely. You do have the RAMPs and Arduino fully seated onto each other, and no bent pins, right?
You might also try redownloading Marlin (try the 20 tooth variant as well - that's the one I can vouch for) and see if anything changes. If all else fails, I can offer you my config, but I moved up to Marlin1.0.3-dev, so you would need to get that as well.
A photo of your installed RAMPS might be helpful as well, if possible.

Sorry for the wait, i had state championship for track. So i got all 3 motors up and running!! But now im running into another issue.. When i type on the code foe the motors to go down to 50mm above the heat bed, it only moves down a little. And is no where near 50mm close to the heat bed. I cant seem to figure out the issue, can you help me out one more time please?¿

Did you home with G28 first? If not, it won't know where it is starting. If Z=0 is not tip on the bed, you need to adjust the value in the Configuration.h until it does. Then G1 Z50 F4000 should put you at 50mm . . .

MANUAL_Z_HOME_POS gets set to the distance from your endstops to the bed. If G1 Z0 ends up above the bed, increase it. If you hit the bed too soon, decrease. MANUAL_X_HOME_POS and MANUAL_Y_HOME_POS both set to 0 on a delta.
(On my Folger Kossel, the Z home is about 254 . . . fwiw . . . although from the Config you posted earlier, that should be where you are set . . . you are using the *MAX* endstops, right? Mine was pretty much good to go using the Folger config guide . . .).

Check which connectors on the RAMPS the endstops are plugged into, or close one at a time by hand and execute M119 (or is it M114? . . ) and see which activates. On the Kossel, all the tower endstops should be MAX. The Folger docs have good pictures of where this wiring goes as well. . .
