Make Mendel MegaBot User Manual

MegaBot

is a latest generation 3D printer, capable of printing 3D objects

uses high quality Linear motion guides. So it is very easy to build. Self locking design

ensures rigid frame with easy steps(Without need of any measurements, during building)

Any person can easily build it by following our Manual.

NOTE:

 Dummy Rails: Dummy rails are given for maintenance purpose, if you will need in future. Be

careful while removing the LM block from the Rail. Put dummy rail on block before removing it.

 4 pin Molex Connector: We give one extra.
 Cooling Fan: Cooling Fan are needed for ABS , If you are using PLA there is no need of Cooling fan
 Hotend: We provide are pre-solder Hotend
 End Stops: When you press Print button, basically all 3 axis move to its HOME position. HOME

position is detected by Mechanical Switch. When switch is pressed, then printer understands that,
it has reached its home.

So there are 3 mechanical switch, 1 for each axis(X,Y,Z).

So, there is a Z Flag, which should go into the Z Optical switch, If z switch is moved during
shipping, then adjust it, so that it is pressed when nozzle is around 0.2 mm distance from
PrintBed..
