Problems with adjusting the extruders squareness(rev. 4)

Recommended Posts

I had to read your post 3 times. Are you talking about steps 9 and 10 in this section?

http://wiki.ultimaker.com/Ultimaker_rev.4_assembly:_Extrusion_head#Parts_needed_in_this_section_4

If so, Move the head to the extremens in X and later Y axes (either order). Watch the belt where it goes through the block and as the block approaches the pulleys you don't want the belt crooked - the pulley should be lined up so the belt is straight. Check in each corner. Slide the pulley back and forth until it seems happiest (centered). The least strain.

You can also try to visually look from above at a rod and belt at the same time. If you move your head so you can just barely see the edges of the belt and the rod at the same time you can tell if they are aligned.

Also if your belts aren't aligned you may hear a ticking sound later.

Anyway just do a good job and it's easy to come back to this step on some future date after you have been printing.

More important is to tighten the hell out of those 8 set screws as they tend to slip when printing.

Thank you for the help, I will figure it out I think.

      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
