Your firmware is not calibrated (all the printer geometry data are somewhat or a lot of wrong). You need to get them into firmware very precisely, preferably with precision below 0.02 mm definitely below 0.1 mm). Otherwise you will hardly be able to print anything well.
As of now you have Z_MAX_POS (or MANUAL_Z_HOME_POS) wrong by about 140 mm.
Read some tutorials about printer calibration first. Later if you want to improve it even more then get a z-probe and read also this: [github.com]
