New Day, new issue! Life’s always an adventure. A while back I purchased the HDZ and have finally gotten it installed on my XXL. All went well during installation, the instructions and Luke’s video were fantastic. When I upgraded CM and began to move the machine, it homed well but then I went to move the Z gantry up and down to test its movements. When the HDZ nears the bottom of its travel, it makes a rubbing/ grating noise. I lubricated the rails and ball screw, no luck. I checked the coupler’s allen screws and all is tight. I attempted to realign the rails according to the instructions and while the noise definitely quieted while the rails were loose, it never ceased. Once I tightened the rails again, the noise went back to the volume it had been initially. I currently have my new 2.2 KW spindle in the mount but unattached otherwise.
Thanks for any thoughts anyone can provide!
