Corey,

I have a thread on the whole build process and some of the issues I ran into and how I resolved them. Also, some of the feedback from other members helped in the design a bit.

See...

I had the same issue, just like you, milled 1/8th off the angle iron and problem solved. Did that to both machines I built.

I'm using Rhino v4 SR9 with RhinoCAM PRO v2.0.4.0

it took about 5 minutes to create each program and that's mostly from going through each option menu. For the most part I pick the type of...

Here's a final cut of the archtop guitar body. 2 programs and 2 minutes with an orbital sander to remove toolmarks...

Nope. The base was built very flat and level and with the 3/4 MDF spoil board bolted on it remained flat, square, and level. This is a wood base, it could be flat one day and curved the next...

The new machine is quite a bit better, worth the time and extra costs. I wanted a larger work area and I wanted smoother finishing. The first momus didn't have any precision issues but between the...

I will be running a final version of the archtop from maple tomorrow. will post some pics. I also have pics in older threads of the aluminum parts I made using my original momus cnc. Some of the...

And my first test cut to make sure the machine wouldnt bind, miss steps, or any other issue that could ruin the machine or part. This is an archtop les paul body I modeled in Autocad, imported to...

Table area is 36"x42" with a working area of 21"x25". Total footprint is 44"x44".

Finally!! All bugs have been fixed. Had to go with the 495 oz in steppers for all axis just to simplify the headaches, overkill yes, but didnt require anymore troubleshooting. Upped the PS to...

Funny you should say that. I just completed my second Momus CNC and don't need the first one. PM me if your interested...

I agree with rigidity but I also found that slower speeds cause this too. Not sure what feedrates your using but anything under 20 ipm I noticed wasnt as smooth as something cut at 60 ipm. One...

approx $150.00 for metal
about $100 for wood
and $1.2 million for bolts

on my larger CNC I used 3/4 aluminum square tube because of the longer lenghts. Worked fine and no need to worry about compression as you can't really crank down the bolts or the bearings won't spin...

Got it all figured out. ordered more 1/2-10 5 start lead screws/ABL nut/coupler and mounted them last thursday. Used 1/8th stepping and problem solved. Running it at 150 IPM without any whipping...

big question is....
whatever happened to Mike_in_Cali?

played around with it for a few more hours. Could only bleed 2 more volts out of the PSU so not much help there. I was able to get better performance out of the 495 oz in on the 10 single start...

using tb6560 drives. I played around with the microstepping all they way back to full step. the only way I can get any decent torque is if I set the velocity very low. At that point...

ger21,

since you have been down the road I am on already maybe you can help me out. My machine is finished. Powered it up tonight. I went with your suggestion on using the 270 oz in motors as...

heres a better screen, last one was small

Well, I did learn a lot of 3d modeling trying to get this done. I was able to get the results in autocad that I was looking for. Still needs some refining and cleaning up but I have a 3d model. ...

well, I made cross-sections at every half inch. put them in the 3d view using 3D align. everyting was coming together nicely until i tried lofting. Lofting operation kept erroring out which im...

I have been building a lot of les pauls lately but have to purchase the bodies. This is the only body style that I do not have gcode for. I am not at my drafting system right now but i will post a...

yes ger, fully aware of the missing magic button hence the thread...jurdleroy, thats the technique i started playing with after i started this thread.

Not sure if you guys know Rhino at all and...

Hi All,

I have a 2d Acad drawing in ortho (top/front/side). I'm using Acad2011 with hopes of taking the 3d model to RhinoCAM. I looked at a few tutorials on this but they were mostly of simple...

OCNC said it perfectly. Just keep in mind when mounting your limit switches you dont want the body of the swith to be anywhere in the path of a bearing. Just the little arm should make contact. ...

Bob, we wouldn't all be here if your design was crap! But yes, constructive critism can improve anything. I, for one, really liked the design and learned a few things when building/using it. I...

WHAT!! you've only built one so far!!! Some of you guys should be on number 3 or 4 by now.

Been working on this as time permits and have made a considerable leap in progress since my last post. Got the base completed as far as I need it to setup the rest. Rails have been installed,...

between family and work they are impacting my timeline here. Started assembly on base beginning of the week, almost done as of 1am this morn. Here's a few pics on progress for those who are...
