Interference on conductive sensor

Posted · Interference on conductive sensor

Hi guys,

 

I do not expect anyone to run into this problem, but wanted to share it anyway. Today I was repairing a printer of one of our customers, they build lettering for advertising. Their conductive sensor did not work anymore. After having ruled out everything and even having installed a new sensor I dissassembled the printing head looking for anything in the head responsible for the interference. Also this yielded no result, I was out of ideas, but just when I was about to give up and take the printer back for even more elaborate research I noticed a neon light behind the printer. What turned out the high frequency transformator that powers this neon lighting caused for interference. We turned of the lighting and all of a sudden everything worked perfectly again. So don't put neon lighting next to your printer😋.I do not expect it to help anyone since it is so specific, but I wanted to share it anyway.

 

Kind regards,
Job van Gennip

    • 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.

    • Ultimaker Cura 5.6 stable released
      Cura now supports Method series printers!
       
      A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
