Unresolved Auto-Level issue head dragging

ROBO 3D R1

I hunted around but can't seem to find anyone with this problem. (I may just not know exactly what to search.)

I finished a print job. Hit print again. Now the head is dragging on the glass. The printer is going through the motions of auto leveling. Then hits the front left corner and sits the print head right on the glass then moves to the center to print. its actually wiping the glue off then bed with the nozzle. It cannot extrude due to the head being forced down onto the bed which causes the extruder to wear a groove in the filament and then jams. I figure its the z-offset but I cannot seem to find it anywhere.. also how would it have changed from printing the same thing 2X working on the first print but failing on the second. No changes have been made to any setting, they are default from the factory. Anyone got any ideas to try?

 

Ok that did make the adjustment but it's still not working correctly. I have even installed the software on a new computer just in case some of the settings got screwed up. Now it is going through the auto level and trying to print. The left side of the bed prints perfect. As the head moves to the right it starts to drag so bad that it quits extruding causing the head to jam. This printer is UNUSABLE!

It seems like the auto level is not doing anything.. Bed is unlevel and it trys to print flat. If this was on my Solidoodle I would manually adjust the bed but there is no option for that so we have an $800 paper weight at this moment.

Please let me know what else to try.

 

Interesting "fix" but the printer is a week old and worked up until a couple days ago. For the price of the printer I should not have to do things like this. My feeling is if it worked properly for a week then there HAS to be something actually wrong. Right?

 

What makes you say that?

 

Well I don't go buy a new car then hot wire it because the key only works sometimes. Your question is very baffling to me, I am not trying to get into any arguments here just trying to get the printer to work as advertised.

 

I just don't see $800 as a "must work each and every time with no need to tinker"

Hell the closest printer to that requirement is the Lulzbot Mini, which retails at 1250 and only has a 152mm x 152mm x 158mm (6in x 6in x 6.2in) build volume

Even that will eventually require some tinkering and maintenance. The technology is just not there yet.

Then the next closest would be 10k at the Stratasys Mojo, compared to that $800 is nothing.

 

My solidoodle 6x6x6 is 2 years old.. Paid $400 for it and it worked unmodified for a year before we started to "tweak it". But neither of these has anything to do with my problem. I get the fact that 3d printers are a tinkerers toy. This printer is sitting in a hackerspace. We have 4 3d printers in the building that we modify all the time. The problem is this is new and unmodified and it should work as advertised. I came here for answers not to get flamed for wanting a product to work.

 

Just curious as to the thought process behind that. Not flaming you at all. Just making sure your expectations are set appropriately.

You're probably using MatterControl right? If you exit out and reopen after each print does that help the issue?

 

@WheresWaldo Man you are so dead on when you say a paper punch cut out fits perfect.. your solution works as a good temp fix thanks.
