Hello folks,
I am currently researching to build my own 3D printer and was wondering about the heated bed.
I am thinking to buy a Dual Power MK2B Heated Bed, and then buying a glass sheet (cut to size), to place it on the bed.
What I was wondering how would I make sure the bed is level, as the glass sheet has no holes for any bed leveling screws
many thanks

I’m not a fan of glass but those who are often use what are called “swiss clips”.

Swiss clips are way of mounting a sheet of glass to the heated bed. With that I am to assume the sheet of glass will be level.
I was also considering a sheet of aluminium, but still have the same problem.
Will each corner of the sheet of aluminium/glass be level.

If you’re not prepared to engineer your own design for mounting/framing the bed then you should probably buy a kit.

Found a way round it, I can get pre cut holes within the glass sheet or aluminium sheet, allowing bed leveling screws to pass right through.
That solves the problem

If any one is having the same problem as me here is the answer.
A standard MK2B Heated Bed essentially has two dimensions:
- 200 mm x 200 mm active heated area.
- 209 mm center-to-center mounting holes (outside the active area).
What this means is, placing 200 mm x 200 mm glass sheet and attaching it to the PCB using bulldog clips won’t cover any of the screw holes of the PCB. Still allowing the bed leveling screws to poke through and be adjusted (Illustrated below).
You could buy a 209 mm x 209 mm glass sheet with pre cut holes, allowing the bed leveling screws to poke through the glass sheet and the PCB. Advantages of this method is it makes sure the sheet of glass does not move under any vibrations but the main disadvantage is you cannot remove glass sheet for easy access.
