Printhead all over the place.

Recommended Posts

Posted · Printhead all over the place.

Today I had some extrusion problems, removed the hot end a few times and now it printed about 1cm z-height and the printhead started to go all over the place. It kept extruding well though and extruded something cotton like. The printhead was in areas where it did not belong. What could have caused this?

I used Cura 12.07 and used the same file with the ulticontroler that worked a day ago.

Cura activates the fan on the 2nd layer, not on the first one. This improves the adhesion of the first layer. Maybe that's your fan problem. No idea about your other problem...

I've had the printhead vanish off in strange directions when the pulleys are not properly screwed onto the drive rods.

But the first few layers are printed at a lower speed, so you could be having issues at higher speeds, which can be anything from lots of slack in the small belts (so they jump over the pulleys), lose pulleys or too little power on the step motors.

I had 5 different issues that night. I did nothing for 2 days and now it printed completely normal and in good quality.

      Through this post I would like to further explain what we are doing, and what you could be doing. 
      Our efforts consist of 2 layers. First; connect medical institutions and hospitals to (local) 3D Printing hubs to help them print parts of which a 3D model already exists. And second, contribute to design the necessary part and then have it printed via a (local) 3D printing hub. Experts are available from within Ultimaker and from within our network of 3D printing experts.
