Hello,

I'm having some quality issues with my Ultimaker2Go. It seems to happen more often when I print taller models (when I mean tall I'm talking maybe 1 inch tall) I had this issue when I first got the UM2G and printed the Ultimaker robot. One of it's ears were perfect and the other wasn't. I thought it might be a bed leveling issue but areas above and below it seem to be fine.

They don't look terrible but I find it weird that one side is better then the other.

Here are some pictures and the setting I was using. I'm sure it's something simple. I haven't tried moving the model off center yet, I might try that later.

    100% fill is not necessary and wastes lots of time and plastic. If you need something strong enough that a car can drive over it - try 3 shells (1.2mm) instead of 2 (.8mm).

    The issue is that because the nozzle is on the left side of the print head, you get more fan on the left side of the model. I'm not sure what the solution is - I guess print cooler. Try printing at 195C on the printer and slow it down to 30mm/sec.

    Of course getting the UM2+ upgrade *might* help as I think it gives you more fan power.

    Or just print something larger - or print 2 at once so one has more time to cool while printing the other.

    The 100% fill was a mistake. I forgot to change it from a previous print. I'm going to change it to 20%.

    I'm going to try printing cooler and slower and I'll let you know how it turns out.

    Will the UM2+ upgrade work on the Go?

    I won't be getting my upgrade for about 2 weeks so I don't know for sure but I strongly suspect it will work fine. I know for sure it can handle the higher wattage heater as I already have a 40W heater on my um2go (and a heated bed). There's nothing else about the upgrade that leads me to think it won't work - certainly the fan thing should be fine. The feeder might require the um2go motor to turn a different direction - but I know you need to load different firmware for the um2go to become a plus anyway. So, yeah, I strongly suspect it will work fine - ask me in a few weeks.

    Plus I don't know for sure if the new fan shroud will help your print on the right side. I just know more fan is better.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
