z-probe failed

Andrew_Pullins · 2016-01-21T23:16:19.000Z

Hello I recently bought a Da Vinci 1.0 and flashed repetier firmware on it. I am having trouble auto leveling my bed. When everything is heated up and the nozzle is cleaned but hitting the drip tray, right when it is about to start checking the bed level it tells me “z-probe failed”. Does anyone know what I can do to get the bed leveled? I tried to level it manually but apparently the bed was too close to the nozzle and the filament just pushed back up into it .self.

EDIT:

I am trying to do this:

Sometimes you really need to scrape the sensor that touches the bed and wipe the little metal tabs clean. When the sensors dirty it will press the bed down past the limit and say Z probe failed

Yes what the other guy said. It’s a contact switch basically. When the probe tip touches the plate it completes the circuit like a switch and that tells the cpu to count the steps from there to the sensor limit on the z axis. Clean the tip well and clean the three contact strips on the bed corners.

I don’t even get to the point where the sensor you ches the bed.

I will try this but the sensor does not even get to the bed before it tells me that the Z-probe failed.

If the sensor doesn’t reach the bed that means the bed’s too low

No mine does te same. What the OP means by not even touching the bed is. The bed is at the proper height. The probe is clean, However, when the head moves towards the pad in the back right it moves 3 mm in the X axis then stops and gives the failed error. It never makes it over the pad before erroring out.

check the forums for correct firmware … zprobe works

Its a grounding issue. Take an alligator clip and attach it to the sheet metal on the frame and printer head. Should go away.

3dpGeek · 2016-01-22T14:16:25.000Z

Does this firmware work on the 2.0?

Andrew_Pullins · 2016-01-22T20:37:41.000Z

If I raise it it will drag against the glass.

Andrew_Pullins · 2016-01-22T20:38:41.000Z

I am pretty sure it does

Andrew_Pullins · 2016-01-22T20:40:34.000Z

Yes this is what mine does.

Mine does the same thing ever since the latest firmware. It seems like it tries to sense the bed level and then the z-axis times out just before it touched the z-probe. There has got to be a setting in the firmware that is off somehow but I cannot find it. I’ve tried raising the z-probe eeprom setting from 10 to 15, but that still doesn’t seem to work. I actually ended up manually leveling the bed using a similar technique as the video and the adding an extra quarter turn to each screw. It seems like it raises the bed just enough to stay within the timeout distance and then I get numbers for the auto-level. I then have to add a negative z-offset in the eeprom to compensate for the high bed height. Hope that helps.

Have you found a solution? I’m very new to this. I resorted to manual but Its still kinda uneven. I wanted the auto to help me out. If you solved the problem please let me know. Thanks

I have not. I got a new printer since I posted this thread and have not tried to flash it yet. I think it might be just a problem of the head being really dirty. But I don’t know.

ok so after looking all over internet for the answer to this question i just played with a few eeprom setting as the issue is not that prob not hitting the bed sensor its that the prob never move over the bed sensor for it to contact so how to resolve this issue

open repetier while connected go to config drop down click on firmware eeprom settings

scroll down till you get to the prob settings and enter these settings this will fix your auto prob fail

Z-PROB-X1 = 5.000

Z-PROB-Y1 = -10.000

Z-PROB-X2 = 5.000

Z-PROB-Y2 = 210.000

Z-PROB-X3 = 190.000

Z-PROB-Y3 = 210.000

Hope this helps guys any feedback would be great
