That worked!! But with one issue!! For some reason when the filament gets the the extruder it makes a jamming type noise? Like something isnt allowing the filament to pass through. Do you think this is due to the head crashing so frequently before that i should get a new hextruder head?

Hey forum! I haven't been able to start printing yet due to a problem with me kossel 2020. The ejector that sends the pla through the plastic tube into the extruder seems to be very figity. What i mean by this is when using marlin and it starts printing the ejector wont move any pla what so ever. No idea why.. but when i connect my printer to pronterface and make sure bith my bed and extruder are

Goodmornin fourm!! Finally after about a year i basically have my 3d printer working in the aspect that it will only dry print. I need some expertise on 2 on going issues ive encountered. The first and foremost issue is my extruder not wanting to move any of my material into the nozzel to print. The gears simply dont move unless you do a manual control of some sort. Also! For some reason one of m

Pronterface can't directly control the towers - it just sends positions in X, Y, Z coordinates, and Marlin calculates the associated tower positions, and moves them accordingly. IE, for a Z move, all three should move vertically the same amount . . . if not, then either steps/mm for that tower or microstepping on it's driver is wrong.
And yes, the towers are referred to a X, Y, and

You might be better served to try the spare driver first - motors are passive, and pretty hard to break . . .
Check DEFAULT_MAX_FEEDRATE as well as DEFAULT_STEPS_PER_UNIT for the extruder as well. Also note that Pronterface uses mm/*minute* for extruder speed, so you need a pretty big number to get much movement.

Ok will do!! Also i learned that the tower is still crashing.

What you have never mentioned is exactly what you are doing (or trying to do) that causes this to happen?
Not knowing the cause, makes it very difficult to be of much help, although the simplest is simply trying to print thjngs that are too big. I suppose that if you errantly set up your slicer with 0,0 on a corner and not in the center (as it should be), it would offset everythi

X=76, Y=76, doing the geometry gives a radius of 107, which *should* bottom things out - it's beyond the maximum radius of this printer. X=76, Y=0 is a radius of 76, X=0, Y=76 is a radius of 76, and X=53.7, Y=53.7 is a radius of 76 . . .
It still sounds like there is no problem with the printer . . . . and keep in mind that the print area is a circle, not a square . .

If you hit the bottom stop, then the question becomes (as I said above), are you trying to print something larger than your printer is capable of? This printer, build as per the docs, has a max radius of about 76mm . . . . limited, as you have seen by the rods being horizontal. If you print a modest square or cube, is it square or distorted? And for that matter what are you trying t

Bottoms out as in hits the stop? How horizontal are the rods when that happens? If pretty much horizontal, then you have hit the maximum diameter you can print with that rod length. If not, you likely have your linear rails mounted too high on the towers, and will need to shift them down.
if things are distorted, and X is moving too far (although I would think this would be obvious

Tim!! Sorry for such an absence work got to me!
Fortunately your idea of installing the 20 tooth firmware worked!! It fixed the bed crashing issue!! Now unfortunately theres one more issue. It seems like the X axis carrige mount bottoms out when trying to print. Nothing else does but for some reason that tower does. Would you know the possible issue?

Tim,
Im not exactly sure where to find the probable_area in config.H. and i did notice and at this point itd worth saying that in folger techs manual the config for Manual_Z_Home_Pos is 253.9, mine is 480.45 due to the fact that when i entered g1 z50 f4000 the extruder was no where near 50mm above the bed. More like 200mm. Could this be the possible issue in thatchanging this variable so grea

Tim,
Still seem to have the same issue as noted before. I noticed when the auto level starts it only does half of the heat bed not the full thing, which could make sense why the hotend is crashing on the part of the bed that the auto level doesn't go over with. Would you know why this does this???
By the way i really do appreciate you helping me out! I really wanna pront something and you're

Dont want to sound majorly uneductated but once i do the paper test to each tower how do i tell the printer to set that. In the firmware what am I looking for to set it the numbers correctly?

Have you calibrated the Z axis, and the printer in general? If you manually give it G1 Z0 F3000, where does the tip end up? Where it parks immediately prior to printing isn't at Z=0 . . . it's wherever your start gcode tells it to go, and once up to temp, it's going to move to the first layer height, which in your case, appears to be below the bed.

Yes I have calibrated the Z axis, using a sheet of paper and determining how low the nozzle should go. I also noticed when calibrating that when the extruder moves to the edge of the bed it goes down, which is what im assuming is the issue as to why the extruder is going into the bed. Im going to test what you asked did and ill get back to you.

Your gcode either needs to execute a G28 for manual level, or a G28/M401/G29/M402 (The M401/M402 deploy and retract the probe) for auto, and it is your task to insert these commands in the start gcode in your slicer - none of this is assumed, automatic, or initiated by the firmware.
I also *strongly* suggest that you do a good manual calibration no matter what . . . at the very lea

Hello everyone! Finally got my printer basically working for the most part. And now im running into an issue when printing. Here's the issue: when i click print everything works fine, bed and extruder heat up, printer hits endstops then comes down 30mm above bed. Then when it tries to start printing in comes down to about 1mm off the beds surface starts to move, then basically goes into the bed

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. . .

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

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 . . .

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?
