Hi,
When I first set up my K8400 it worked perfectly the first time (3 weeks ago). After about 5-10 prints, 10-20 hours of printing I started getting issues.
On my last print I also had a 1 mm shifted/distorted level as well, which indicate something is wrong on the y-axis.
I’ve now loosen all the pulleys and belts, and tried to realign all rods on the y and x-axis. The biggest difference was about 1mm. I’ve now readjusted all to within 0,3 mm on each axis.
When I move it around with my hand it is very smooth on the x-axis, but less so on the y-axis. Actually when I move the y-axis towards the back of the printer the resistance is very high. So I believe this is my issue.
However I don’t seem to find the reason for it. The rods seem parallell. The pulleys and belts are aligned. And the pulleys are all tightened with two M3 x 4mm SET SCREW.
Any tips?
The picture below show the position with the biggest resistance on the y-axis. It is actually so big that it is difficult to move it by hand.
