XYZ calibration fails unless probe is all the way down
Just assembled my first MK3. Everything went smoothly up to the moment of calibration - it ended ip with "xyz calibration failed please consult the manual". The process failed to find the very first homing spot. Can't seem find what is wrong with it - everything looks assembled correctly. belt tension is good. When troubleshooting it, i tried to adjust the probe - and finally made it to calibrate successfully after moving it all the way down - almost level with the nozzle, way lower than required to prevent the nozzle catching paper sheet during XYZ calibration.
So I calibrated it with probe down, then readjusted the probe to normal height (zip tie method), did first level print calibration. axis alignment reported is almost perfect.
So far so good - it printed 3d logo, now printing another part. However, I am still concerned the XYZ calibration did not work in a proper probe position. Thinking I could have made mistake in extrusion assembly.
Should I be concerned? any idea what could be wrong?
