Fantastic build you have there.
I'm not sure how much Momus is left in that with the conversion to rack and pinion for the X and belt for the Z, but it looks really good.

Hello guys and ladies , if there are any here :P
I would like to show you what I have done so far, I bought the plans couple months ago and I found these to be the most detailed than any other plans I had a look at….
My only problem was, how to adapt these plans of the machine for the servo motors that I bought over a year ago that were not used since as I couldn’t get them working under control of Mach3 or EMC2.
But thanks to one person from this forum who pointed me, what needs to be done to get them turning under computer control.
My machine is built mostly out of steel and some parts had to be made out of aluminium such as belt mounts etc. The other problem was that the plans are in inches so had to convert the sizes into metric and find the appropriate steel bars.
The build is almost finished, almost because I can’t find a source to get any good 4 core screened cables, the ones I have wired the motors to the drives now aren’t screened what in result causes the electrical noise.
That’s it for now, will upload new pictures soon….

Nice!
Wow, beautiful adaptation of the design. Yes, more photos please, especially of that Z axis drive setup. Any chance of posting any video of those servos in action, once you get the wiring sorted?
What is the overall size of the machine?
I was thinking same, at this point why were the plans even purchasedOriginally Posted by Michael In Cali
One think I want to change is the belts, next machine I am gonna use a screw drive system.

Well, the motive force is different, but the traveling parts are about the same. Thats the part that actually attracted me to this design in the first place.
Any thought of a "cheap" machnie are out the window though.
First of all, thanks for kind words about my build and sure, I will upload some videos once I get everything sorted. The machine is 1x1m but the working area is about 850x850 mm. I am going to paint some parts in blue this weekend so I will take some photos of the Z axis when it will be disassembled.
vigen20, Looks like you are implementing almost the exact mods that have been floating around in my head.
The changes I have in mind from what you are doing is using v-groove bearings and will be using the 570oz-in stepper motors from my existing machine and was thinking of just direct driving (no 3:1 gearing). My current diy table I am direct driving chain for all 3 axis.
I'm very interested in seeing how well the X-axis rack & pinion works out the way you implemented it. Are you able to provide enough pressure on the pinion gear to keep it engaged with the rack under heavy forces on the router?

I think Vigen20 is show-boating here. Nothing in his design shows it all started with the plans we all used. It is a gorgeous build but I don't think this is the right forum for it. Just my 2 cents.

Bill, I disagree.
The basic transport is very Momus. The motive force certainly isn't. I do think it belongs here.
Thanks Michael for supporting me :P I bought the plans so I tried to follow them as far as I could. I have welded the frame and I bought the servo motors much earlier than I found Momus plans on the internet. Having this opportunity I had to adapt this plans and I still think my thread should belong to this section of the forum as the X,Y and Z are basically based again on Momus plans. Because the frame is a bit bigger than the one from the plans I couldn't use a belt on one side for the X axis so thats why I have Rack and Pinion system on it, if it won't work I will go for the belts on both sides of the frame.
P.S Sorry guys for my English , I hope its understandable for you....
The basic transport is the same as any CNC (X,Y,Z) and it is just a gantry design but nothing in it has any hint of the plans. This forum is for people who used the plans, their progress, some of the deviations/changes they went with, etc.
Again, beautiful machine, I would buy those plans in an instant, but not in the realm of what would be considered "Momus".
If we can take any 3-axis gantry designed CNC router and call it a Momus then I will agree with you MikeHell if I could take my Ford and put a Ferrari emblem on it and get a $100K for it I would do that in a heartbeat
