The following can be done with custom firmware without using pronterface:
https://github.com/ThomasToka/MarlinFirmware/releases/latest

To set probe offset for the included model, run: 
M851 X-44 Y0 Z0

Before disassembling the printer or changing the mounting plate, manually try to level the bed as flat as possible.

Below can be used with pronterface; install CH340 driver if pronterface cannot detect printer.

Get current bed mesh values using M420 V .

1. Turn the 4 knobs base on the reported values at the 4 corners 
2. Run G29 auto bed level to get the new adjusted value 
3. Repeat steps 1 and 2 until leveled 
4. (optional) Visualize the bed mesh to check if the bed is warped beyond saving (http://lokspace.eu/3d-printer-auto-bed-leveling-mesh-visualizer/) 
5. use 0 offset mount if the bed cannot be leveled properly and doc instruction didn't help. (Recommended to print with PETG, PLA breaks quite easily)
