Wow.

I am as impressed with your documentation as I am with your craftsmanship and ingenuity. 'Ya gotta love Moglice!

Very nice work. Very nice design. Very nice of you to share. Thanks!

That looks great. It looks professionally built. Now you got me wanting a 4x8 machine, lol.

Great site and router! Thanks for sharing.

very nice router. i have bookmarked your site for reading. looks like you were planning a dual z axis. how would this work in software?

[oneyaker]

Thank you.
The W axis would be treated like a z axis in Visual Mill since they assume the fourth axis to be rotary. You take the g code for the psudo Z axis (W), substitute, W for Z in the code (so that Mach2 treats is as the 4th axis), paste the code into the main program, enter an G54-59 offset before running the W axis (cancel offset when you want to run the real Z axis) . This offset is a known distance between the centers of the Z and W axis in both x and y directions. The spindle command will be taken from either mist or flood external output. I have it running vacuum and one spindle so there is one more slot for the second spindle. If I need more outputs, I will install a second parallel port.
This will be done for production purposes so that once the code is optimized you do not need to mess with it ever. I hope it makes sense.

yes that helps. I was also looking at the kayaks, I would love to make a cape ann one day.

What a diy machine!!!

I read your documentation and I was a little confused as to which parts of the frame were welded. As I understand it, small components (brackets, angle, flanges and plates) were tacked welded to the major components and then bolted together. Is this correct? How effective is the "home-made" moglice at dampening vibration?

I like it! Now......my curiosity is very much aroused over the joinery technique of the steel structure. Also, the steel-cutting circular saw........that works pretty well, eh? I'm impressed with the precision of your structural elements. It takes a lot of will and a good mind set to maintain that type of precision work from start to end. A lot of people make a few precise cuts and then progressively start allowing a little slop here, a little slop there.....etc. I really would like to find out more about the epoxy/metal powder joints and exactly how you set up to "glue" them up. Again, outstanding job.

Did you weld all the flanges on that you used for bolting?

The most impressive homebuilt machine I have seen. Your committment to accuracy,precision and workmanship is inspiring me to produce such a machine. I am somewhat curious about the ability of the metal saw to create such clean cuts which are cool to the touch after cutting.

do you have any updates on your machine?
