The Momus build is moving into what I call the 'much work, little progress seen' stage.  The torsion box construction is super rigid but unlike a metal, wood surfaces require finishing for visual appeal and to protect it from cutting fluids, spilled coffee, cold beverage condensation, etc. I am in the fill, sand, refill, repeat mode. Some builders have just slapped paint on it and moved on but my personal standards won't allow me to do that.

Here is a shot (also posted on CNC Zone) with the electronics chassis test fit into their locations in the base and the covers just sitting in their general location. The front cover will be hinged to the back cover and will flip up to access the cutting tool and the work piece.The back cover is not in position but slid back and resting on some bar clamps to allow me access for finish work on the front. The back cover will be attached to the base. Lighting will be installed inside the back cover to allow you to watch. Plexiglass/Lexan windows will be installed in the big hole in front and the trapezoid holes on either side of the front cover. 

The more I work with Bondo, the more I appreciate the stuff. The working time is very short.

The Gecko G540 driver supports 4 stepper motors and two relays. I have the two relays and their separate power supply mounted in the same chassis as the Gecko with an Estop slap switch. The rear chassis holds the motor power supply and the AC power interface.

Bob has released ver 2.1 of the plans set

Check it out at MomusCNC.

Yay, Monroe is back!

Thanks Monroe. One benefit of the Momus is that *IF* I want to try servo based motion control, I just swap out the motors with that type.

This build is with 380 oz/in steppers and a Gecko540 4 axis driver. My idea is to make a 4th axis assembly much later to allow aluminum tube rotation for all-side cutting.

Great to see you back, Monroe!
I'm still hoping to build a CNC machine, although my interest on a 3D printer head took a different route [1]

:-).

OK! Hey guy's I'm back! And I've made a good deal of progress on the CNC Machine! I'll make some post to get everyone up to date! Let's do this thing!

There has been no update on Bob's webpage about the print head. He has been somewhat quiet on the CNCZone webpage (they are completely reworking that site at this time).

Yesterday I bought the 3/4" plywood for the base assembly and spent several hours rough cutting the parts for it. Today that work will continue.

When running, I there are several plans for printheads online so if Bob is slow to publish his efforts, there are always others to try.

The router can be removed from the Z axis rail and the print head bolted on. Filament feed, power etc..that will have to be worked out.

First things first. Get the machine built and aligned.
