that are being developed by Momus CNC. It will also be used to post
modifications and improvements to the machine design that have not

We are currently working on a print head and
extruder that will bolt onto the standard Momus
CNC router, turning it into a 3d printer.
The Momus CNC router has a combination of
qualities that make it well suited for use as a 3d
printer. In particular, its mechanical resolution and
high speed movement.
This design uses standalone electronics to control
the nozzle and printbed temperatures. A PID
controller modulates the temperature of a
line-voltage cartridge heater that is embedded
alongside the nozzle. The 4th axis of Mach3 will
be used to control the extruder, which uses a
small stepper motor.

The parts for the extruder and nozzle will be able
to be fabricated using the momus cnc router.
The design of the momus cnc router underwent
significant revisions between the first release of
the plans and the current version (2.0), which
was released in May 2012. Many of the changes
made to the design of version 2.0 were done
with the intent that the machine would be easier

Momus CNC machine, with a travel of
approximately 50" x 50". It will use a stepper
motor drive on each end of the gantry axis, and
these will be be slaved together through the
While the enclosed design of the machine
effectively contains dust, it can still be beneficial
to equip the router with a vacuum dust collection
system. Numerous builders have already added
such systems to their machines.
