calibration failed! check the axes and try again.  

RE: calibration failed! check the axes and try again.

Additional information:  During the initial self test I am getting an error.  Selftest Error! Please check Axis length Axis X.  I had this error before but I was able to resolve it by adjusting the gear attached to the x motor and adjusting the belt.  The error has returned.  The extruder moves smoothly across the X axis smooth bars when done manually.  Cables are not binding or touching the sides in the back.

Update to last post.  I reviewed the X Axis installation instructions and found that the X Axis motor pulley was on upside down.  I fixed that and the machine will pass the initial self test with ease.  

The machine is still choking on the XYX calibration as described in the first post.  

Does anyone know the customer service email address or is this forum one's only course of action for resolving problems?  Thanks very much.

I thought you need a steel sheet on the bed to do calibration.   At least on the MK3S, I don't have the Plus upgrade.

For the X calibration, it means there is too much drag in the system.  Try loosening the screws that hold the bearings on the extruder body - those don't need to be very tight at all and if you tighten them down you may see this calibration error.  Another common cause is the zip ties being mispositioned on the wire loom.

Thanks for the reply.  For the MKS3+ the procedure explicitly states that the steel sheet needs to be removed.  I've tried going through the procedure with the steel sheet in place and it said to remove it.

I solved the X Axis problem by putting the X Axis motor pulley in the correct orientation.  I had it upside down.  X Axis works fine now. Still having an issue with the XYZ calibration.

Thanks.

I contacted them and they were able to get my stupid mistake figured out pretty quickly.  Sent them a video and some pictures and they saw that I had installed my hot end improperly.  Thanks for the response and thanks to Dominik and Adam at Prusa customer support.  Those guys are fantastic!

Seems like Josef may be a bit too liberal with his time off but they are really great.
