    • Plugins to the UI

      Hello
      i did a small web app for calibrating dual extruders
      it would be nice to have it as a plugin in the UI some how
      also then the plugin can have more direct actions to macros and more

    • RE: New beta firmware release 1.20beta10

      Tryning the new probe mode 7

    • RE: Horrible print quality since upgrading

      I had similar problems with my drive shaft extruder
      it was like long waves
      the solution for me was to make a more solid mount for the e3d/heatsink
      i was using the normal e3d heatsink with a clamp at the top
      but i guess the cable made it "swing a little" making this long waves
      after changing to the aero heatsink (it has 2 screw holes , so it can be screwdown very tight)
      this problem vent a way

      may not be your problem but try to add some straps or something to test if that's your problem

    • RE: New beta firmware 1.20beta8

      i can comfirm the wrong direction on homing as mchiriciuc says (CoreXY )
      it happens sometimes but most of the times it works fine

      i have not yet upgrade to the latest FW will do that soon
      and do more test

    • RE: Stall detection as end stop

      got it working
      the Z was much harder to finde a working settings
      i hade do play with speeed,current and sensitivity

      There was problem pushing the home all button
      one by one was no problem but home all sometimes ignored(? or stall was detected right away) one of the axis
      it helped to get the motor runing before adding the S1 flag
      and i hade to remove the 2 bump after the hit to get it 100%

      *how do set the printer not to use the probe and use stall when runing mesh grid

      *how can do a test to see repeatability (is it called that ?)
