Hitting heat bed on calibration point 4
Hi guys,
I really need your help on this.
I just bought and assemble an original prusa, but i'm having trouble calibrating it. It is hitting the heat bed on calibration poit 4 really hard.
Auto home works fine.
Calibrate z axis works fine.
But on Calibrating xyz, on the second pass it hits the heatbed. The curiouse thing is that on the first pass (just 4 points) works fine.
thanks for the help

Make sure the Z frame is seating fully into the threaded rods on the Y carriage. Loosen both front m10 nuts where it hugs the Z frame and push it down further to make sure its fully seated and flat into both threaded rods and re tighten your m10 nuts while putting pressure down to keep it flush. If its not seated properly it will raise on a corner and your hot end will touch the bed.
