Cura calibration do not work

Recommended Posts

I build me Ultimaker und want to first start it

I start Cura and do the firmware update. (I hope it was not a mistake) After the Firmware update the checkup wizard start. But after some seconds i get a message to move the extrude to the middle, but the extruder is in the middle.

here the log:

Object 0x7fd3bb5e0210 of class NSConcreteMapTable autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug

Ok, Thank you.

I have switched to Windows and i installed Cura to see weather the check runs there.

But i still have a Problem. I failed again. After temperature check i should press X End in front left corner. I moved the extruder bye hand to left but nothing happens.

Check the switch with a multi-meter, also I took about 5 attempts to get CURA to "see" the switches going. For me it certainly was not a case of quickly clicking each switch and being done in 15 seconds, sometimes when it asked for the X LH endstop I would have to sit there clicking it for half a minuite before CURA reacted.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
