Topic: WTF have I gotten myself into....

Been trolling these forums for a couple of weeks and used some of the information to correct issues I was having, thanks very much for that ya'll. Seems in the past 3 weeks since I've had my DaVinci Duo I've encountered every problem possible and fixed them for the most part except for my current issue.

It seems to me it would be a sensor error with the X axis as when I set it to calibrate or it cleans the nozzles it tries to pull the carriage over to the right instead of going to the left and makes a god awful noise as it does it. The odd part is that it knows where the carriage is when it comes to starting a print which then creates another problem.

Few minutes into a print it will step out to the left and try to complete the rest of the print like that.

UPDATE: Just tried to get it to print after removing the side cover, now it stepped way off to the right and started doing all kinds of weird lines. It has however, stopped trying to go right while cleaning the nozzles....

Anyone else with a Duo encounter problems like this ???

-----------------------------------------
Modifications I've done
- Replaced the thumb screws on the bed for adjustment with the longer wing nuts printed from Thingiverse.
- Clipped the connectors off of the wires leading to the heaters and directly wired them

Those two little things right there saved me a world of headache and now I have no problems with the extruders heating up and I can level the bed usually in 2 passes now that I've remember the relation between the adjustment points and numbers on the screen.

Re: WTF have I gotten myself into....

Mine printed fine right outta the box after a bed calibration for months...my heated bed just had to be sent back but everything else is fine.  I had 1 print shift on me after an hour or so (layer moved a quarter inch to the left and kept printing ) that had to be scrapped, i just restarted everything and was fine after that.
good luck

Re: WTF have I gotten myself into....

okay, so I think I've tracked the source of the problem down to the wiring harness... I Removed the side cover there and then clipped off the zip ties and it hasn't messed up yet.... the harness hangs out the side but doesn't seem to be stressing any one area along the line and it doesn't travel around as much on the end closest the motor.

What happened with your bed if you don't mind me asking ???

Mine worked fine for about 2-3 weeks with no problems, then I got the warning it needed to be calibrated and thus began that nightmare which I was able to rectify. Then the extruders quit heating up, fixed that problem as well.

One afternoon the bed would only heat to 30c...had to remove and send back for replacement...still waiting for the new one to come back.

Re: WTF have I gotten myself into....

30C should be your room temperature. When you try to heat your bed does it get warm at all? This could be two issues that is semi easy to repair. It could be a bad thermocouple sensor, or you could have a loose connection in your heating wires.
