I just completed my first ever 3d printer build a prusa 13 mk2s, I’ve ran a few calibration test to get my bottom layer right and then a couple models. All was going great calibration came back saying the x/y/z were perpendicular after completing the build.
What is strange on trying to run a print tonight without changing anything the end stops on the Y & X axis are now not being reached the motors are skipping while trying to reach the stop ends. After powering down and moving the x and y axis manually i can get the to reach the stop ends but you have to really push past the natural range to each axis. On construction the x & y axis stop ends were reached easily, how and what could cause this sudden change on both axis? I’m a complete noob here any help much appreciated.
Do you have any pictures of the belt path/linear rods? Generally if you get binding near the ends like that it’s because something is not aligned right. Even belts, if they don’t have a linear travel path can bind up near the ends.
I thanks for reply. I forgot to update the post to say i’ve fixed the issue. Or actually three issues. These were as follows.
1, The wire harness from the extruder has extremely tight clearance to the rambo cover when i did my build. It was fine when i did my cable management. After the cables had settle the cable wrap had started catching the rambo housing stopping the x axis reading the stop end.
2, The y axis stop end was not getting reached as the little excess from the belt sticking out from the belt holder fixed to the bed starting catching on the y motor restricting the movement. The manual says do not cut this belt but had to snip about 5mm off the end to clear the motor.
3, Although currently this was not effecting the print the bolts to the y axis carriage needed a quick tighten up. The instructions on the assembly says do not over tighten as can cause damage to printed parts but if you do not nip up just enough they can work loose fairly quickly.
