Smart effector first layer issues

Make sure that the spacing between each pair of towers is the same at the top, the bottom, and half way between top and bottom from duets website

The spacing between the bearings at the top of a pair of rods must be exactly the same as the spacing between the bearings at the bottom

get the linked version with the flying extruder mounting holes easier to mount the extruder

One thing I did change on my bed was the standoffs under it the blue discs if you take 2 off and measure them mine were way way off in size each to each I replaced them with springs but that was after getting my setup sorted

Hello, I tried printing the parts yesterday (small parts usually work after some fiddling) and halfway a belt snapt, thats what you get after to much tensioning for more precision... But anyway, I changed all the belts to new ones with a metal core which I had as spare, tensioned the same and printed the small parts again, which went easy somehow. So I tried to print the big part to be sure. Perfect first layer without a mesh, just after a quick delta calibration.
No idea what was wrong with the other belts, could not find any problems on them and the were installed correcly and tried several amounts of tension over the last year.
I will install the new mounts for the arms anyway to remove the 0.5mm, but they do not couse the first layer issue.
Thanks a lot for al the help, It was a hardware foult afterall, altough I am still not sure what was wrong with them.
The support on the forum is great, really thanks a lot.
Should I close the thread somehow to show it is fixed?
