PRusa i3 rework Expand bed to 300x200
March 14, 2017 11:35AM
Hello, how are you people?
Im looking for help with the design of a upgrade bed from my prusa i3 rework.
Actually the bed iam using is a 200x200mm heat bed and the length of the threaded rod is 38cm on the Y axis. and the smooth rod 35cm.
How long must be the rod threaded and smooth rod that will need to be able to install this larger bed And that it can print correctly on its entire surface?

Thanks!

Its not that hard,

distance of y carriage bearing end to bearing end + bed length in the Y = smooth rod distance

If you needed help with this maybe just stick to kit builds

plus a little bit to allow you to mount the smooth rods.....

My P3 steel has Y smooth rods 520mm long and a 200x300 build platform
