Calibration XY - Y grid in not printed (BUG)

Recommended Posts

Posted (edited) · Calibration XY - Y grid in not printed (BUG)

I am using Ultimaker 3 and trying to do the XY levelling for the first time. However, the printer does not seem to print the Y grid, while the X grid prints fine. Apparently this happens due to the material not being extruded, and because Y is being printed first, no material comes out. When in X, the material already reaches the nozzle and prints the grid. I know that the material is pulled from the nozzle when not in use. But this seems like a stupid setup, probably a bug in the software? 


The X and Y grids print fine when I move the material manually prior  to calibration


Shouldn't Ultimaker move the material first before printing the grids like in the normal print?

    Yeah, looks like you've been caught out by a bug in Ultimaker's brand new 'Unified' firmware. The 'Unified' being important because it's now been 2 and a half weeks since I've been able to X/Y calibrate either of our printers...

    yep it's a known and reported bug, and as you mention there's an easy workaround, just push the material manually (open the feeder lever and just push filament to the end) and all is good.

    Or you can just enter 0,0 for the calibration values as that is usually close enough for most things one would print.  The units for calibration are 0.1mm.  Unfortunately another thing about the upgrade is it seems to have changed the "old" xy cal values to random numbers sometimes as large as 30 (3mm).

      • 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.
