"bent" y-axis on a cold printer
Hello everyone,
As you can see, the y-axis first goes up, before going down somebody tell me, how I can fix this?
I am aware, that this might happen when heating up, but this printer is at room temperature.

This is what the hot bed looks like:
Did you tighten down one end of the rail then the other than snug up the rest of the linear rail bolts? That's a no-no. You need to work your way across the rail, otherwise as you have found, you have created a 'cold bow' on the assy. In essence, you pinned the two ends, then tried to pull the middle down to the extrusion so it will bow. BTDT. we all live and learn. since it's in both axis, this ame procedure needs to be 're-performed' correctly along your Y axis rails.

Thank you, but unfortunately that is not what I did. I started at the front and then moved the carriage back and as I did so I tightened the bolts
