Zaxis starts print 3cm above platform (not calibration fault)


Recommended Posts

Posted · Zaxis starts print 3cm above platform (not calibration fault)

Hi everybody,

First of all, this problem is not a callibration fault. Every other print starts perfectly fine.

I'm trying to print the bottom plate for the quadcopter on thingiverse. (http://www.thingiverse.com/thing:49634) Slicing in cura seems ok, no errors.

Then when i start the print: Zaxis reaches 0, moves up a bit (like it normally does), extrudes a bit, then starts printing +- 3cm above platform! (Ulticontroller Zheight 0,3)

Could it be that the bottom plate is too big for the ultimaker?

Cura info: X=204,79mm; Y=134,71mm Z=19.04mm

if you open the file in cura you'll see that the Xdimension is really at the edge of the platform... and there is no room for the 1st outher line the printer usually makes...

I don't really want to rescale the bottom plate because all the other parts are all printed.. :)

Any help would be great!!

thx, Ben

    I had a similar thing happen the other day, I was trying to print something right on the 205mm size limits and the Ultimaker was hitting the X limit switch and did exactly what you are seeing.

    Try printing without a skirt or rotating the print around 45 degrees so the longest dimensions point to the corners of the print bed.

    I hope that makes sense

    I recommend you move whichever axis is hitting the limit until it hits the limit and note *exactly* how much you can move the axis before it hits the limit. Then before printing your gcode make sure it doesn't hit that distance using the methods Bob mentions (turn off skirt, rotate part).

    Thx Bob,

    Sometimes the solution is very simple :)

    Turning the print 45degrees did the trick! And prints fine as you can see.

    Maybe Cura should build in an error message for this problem...

    thx for the input people!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
         
         
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
         
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
         
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
         

         
        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura 5.3.0-Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
         
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
