Chasing an impossible problem (SOLVED!)

So occasionally I get a weird artifact on the sidewalls of my prints.

Sometimes it's only PART of a print. Doesn't appear to be related to speed, acceleration, jerk, or anything else. I've tried them all.

And last night I finally worked it out.

I'll show a photo first:

Anyone have an idea what it is? Anyone want to take a guess?

*drumroll*

Ok, here's the answer. It's a second printer on the same table, shaking! It's my old MakerBot Replicator 1XL. When printing at 85mm/sec, the whole machine shakes the table enough that it was bouncing the build platform on the UM2 !!

Had another print going, stopped the MB, and the problem went away. Started a new print.... and it came back. This has been going on for AGES.

Problem solved!

    Similar issue, I recently moved my printer from a more stable table, to a wobbly table, and have noticed that the movement in the build plate increased. It will make its way back to the Solid table soon.

    I put my UM1 on 4 vibration dampening pads, each pad is 6" x 1" square with 1/2" of cork sandwiched between a 1/4" thick piece of ribbed rubber on each side. I also added 16lbs of rubberized flex metal weights to the inside of the frame on the bottom platform, it doesn't shake much now.

      • 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.
