Thanks paul_delta, will do. EDIT: Um, this is a stupid question - but what is the proper way to disable my z-probe? I tried to disable it by uncommenting the following line in my Configuration.h file:
EDIT #2: I figured out how to properly disable end stops (by editing pins.h) using information from this webpage: [ohmeye.com]
(hopefully, others who encounter the same problems as I will see this post and find it helpful). However, I'm still seeing the same behavior with all servos moving in sync to raise the print head straight up no matter what kind of input I give them from Repetier-host..

//#define DISABLE_MIN_ENDSTOPS
But that didn't seem to make any difference.... I apologize for the newb questions. I appreciate your help a LOT.

triggered z-min is the source of problem. disable your probe completely and try again.

Hi everyone,
I have been following this thread for quite a while as I slowly have been putting together my FT Kossel RevB. I finally got it all together and powered up, but as my last post above shows, I have some issues... One is the Z_MIN always being TRIGGERED regardless of whether or not the light comes on, but I am going to try re-wiring it (it currently has the blue wire connected to ground, whereas I see that most people have it connected to V-). If that doesn't fix it, I will try removing the resistors and just connecting to 5V as a previous poster mentioned it works for him that way..
My main issue though, is that using Repetier-Host (and the FT Marlin firmware compiled using Arduino and flashed with no errors), no matter what I do with the manual controls, they all just result in all the carriages moving up until they hit the end stops... and they don't stop when hitting the end stops either. If I try to do a 0.1mm move on Z, it just goes up and keeps going up. Same if I try to do a move on X or Y or even extruder (!).. It was not like this at first, so I thought perhaps I had messed up the firmware, so I re-compiled the FT firmware (with no changes) and reuploaded to the printer... same problem still persists though...
Any clues as to why all the movement commands just end up causing the entire print head to move straight up? Did I fry something?
Thanks for all of the help you folks have already given... I'm still learning and all this shared info is great...
Eric

Update:
Still have the same problem of all inputs for moving the head result in the entire carriage assembly moving straight up. I tried changing:
const bool Z_MIN_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.
to:
const bool Z_MIN_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.
and while that resulted in the Z_MIN always reporting "open" (even when I placed some metal under the probe to trigger it), it didn't change the behavior. Should I just disconnect the probe entirely?
Also, I have no idea why, but now the X/Y/Z max end stops work properly (i.e. the carriage does not keep trying to go up after triggering one of the end stops). I do not know why this suddenly started functioning, but it did... progress (?) I guess...

Looks like Marlin doesn't have such option, so you can edit pins.h and change pin to unused. Or disconnect the probe and make sure that firmware returns "open/not triggered" state.

UPDATE #5: Another *facepalm* moment. The extruder works. I just forgot to heat up the extruder first, so the min temp safety was preventing it from working. Yay. Now to get to calibrating.

You can use M302 command to allow cold extrusion - when you will calibrate your extrusion steps. M302 S1 will disallow cold extrusion.

You can clearly see I need to tune my extruder/hotend. But since I haven't even tried to do so yet, I'm happy with where I'm at, relative to a few days ago.

I'd say that the print looks very good and extruder calibration is OK. You can play with retraction amount and speed (and probably reduce hotend temperature) to get rid of these strings.

Do you have any recommendations for retractions settings with the stock extruder?

I just got my rev b delta printer after Christmas and i got it all built and set up and i can get good dimensional prints in the middle of the plate.
But where i am having problems is getting the bed to level, i got the flatness or what ever it talks about in the configuration figured out
and i got the nozzle to pass the paper test under all three towers and in the middle.
The first problem is that when i move the extruder across the x axis the auto level sensor is lined up with it and at the outer edges the extruder tilts and causes the sensor to hit the bed and drag through my prints.
The second problem is that the print bed is still not level even with the auto level turned on or off below is a picture with it off of a astrisk test print first layer.

So that's causing both of my problems the tilt of the extruder in the X and the plate un leveled in the y?

After reading through the previous pages I see that others have found that 255mm rods work better and that they used thicker rods. Where is the best place to get the materials and what are the best materials to get to make these longer rods.

Thanks Paul,I'll have to give them a try what rod length and diameter do you recommend for the rev b. Model, and is there any chance you have a picture of how you built your jig.

My heater plate had a little bow in it; I figured out it's geometry, and with a careful and studious use of my foot, and a copy of Bill Shatner's autobiography (hardcover), I was able to make it as flat as my cheap metal ruler and a bright light source could measure.
