We are setting up a Ultimaker Original + and there is clearly a problem with the homing. Please see the video.

This is upon adding the printer for the first time to CURA and leveling the buildplate.

 

Please Help!

    I built and got a UMO working but I've never tried that particular wizard thing.

     

    Is it supposed to be homing?  If so it's going to the opposite corner than it should be.  You can pick one of the twisted pairs that goes to the connector (where the cable connects to the PCB (printed circuit board) and pop out two of those and swap them.  That will reverse the stepper.  But first see if it is trying to home...

     

    Try pushing on the endstops in the near left corner (front left corner) while doing that movement.  Press them twice (homing goes to those twice).

     

    Actually also make sure you got all the right endstops going to the correct locations on the circuit board.

     

    Also make sure that when you push the head to a corner you hear the end stops click.

     

    Personally I would install pronterface - I find it easier to debug.  It shows the status of the limit switches also in pronterface so you can test those first.  Then you can make sure that +X moves head right and +Y moves the head to the rear.

     

    Get pronterface here. It's free:

    Oh but you need a PC.  Do you have a pc?  In the video you used a mac.

    I dont have a PC.... just the mac.  

     

    We were trying to do the buildplate leveling/calibration when it goes to that corner and doesnt stop. 

     

    This is a new development as the first time we calibrated it homed correctly (front left). Then we had to adjust the Z stop because we were having extruder issues (prints were coming out stringy). After we adjusted the nozzle we tried to recalibrate and the nozzle homing onto the build plate clips - and then did the thing where it seemed to home in the back right corner and ignore the limit.
