I would think dfx but I am no expert.

Yes Paul. A think its the best way. Now I have a problem. I make my design in Corel , use millimeters as my natural system and when I check in Auto Cad it comes out very big . I know there is a simple way to adjust the size but I don't know sow I will have to learn how to do it.
I finished an emergency system to keep clean my work area and it works very decently. I first use it cutting some Styrofoam and the area keep nice and clean. I know it is not good looking but y had to tried it first to see if it works and the results are nice.
There goes some pictures.

Hi Hugo,

You have been busy, good work I like your cuts.

How is the Z axis in terms of stiffness, any backward or sideways movement.

In terms of the file being big in autocad there should be an adjustment in one of the menus for switching from inches to mm, I use another program so I am not much more help.

Hello Jason . Well finally I am ready to start working and tried the machine to see her real capacity. Z axis is very stiff, no lateral movement at all but after I tried those V bearings I use for Y axis y would prefer them because I could redesign Z axis in a lighter way (all those pipes, angles, bolts are unnecessary heavy) Y axis works very nice and show me the importance of a careful alignment. I still have to improve in alignment to be totally satisfied(this is definitely the hardest part building a machine)
X axis is the part I am not satisfied. The adjusting system works great. I can adjust the rail and the angle that holds the bearings, the only problem is that I welded the nuts that holds the bearings, is very hard to be precise and I was learning all by my self to weld sow ........but with the bearings angle adjustment screw I can tigt decently. The funny thing is that when X axis is working the machine moves, maybe because a balance situation of the table and the legs.....well i am just beginning to check and the cuts in Styrofoam looks very precise. Today I am going to cut a sample part in different materials to compare and will be posting the pictures.

Excellent job Hugo, if you are anything like me you didn't have a complete machine shop to make your machine, but still ended up with a fully functioning CNC router at a fraction of the price of a commercially bought version, it may have faults that might bug you but it is still working and pretty damn well, you probably learned a lot about electronics, power supplies, motors and so on... good job!!!!

And remember, you can also use this machine to make a second machine, or at least some nice parts for it, you have my respect

You bet. I think I am ready to start designing my next machine. I got a big problem. I found out I love building this machines and thats is a big $$$$$ problem jajaja . Any way I am having a lot of fun and is nice to share moments with you guys.

Hello friends.
I have not disappeared y just realize that I was not satisfied with my machine, that I have to change the small bearings from my X axis because they were not as rigid as I would like so I decide to use all the little experience y gained after all this year and half and start something more efficient and that I can make some money with (In my country you own a decent CNC machine and there are lots off big opportunities) sow I am getting ready,thanks to a a man, Gerald ,and his MechMate machine. Hope to let you guys know my progress and shears my impressions.

Hey Hugo, been a while, any news or progress on the machine ?

If you are like me you are now thinking of everything that went wrong on the first and planning the second machine...lol

Man that looks like a huge amount of work ...would have been cheaper just to buy some linear bearings -- No?? .If only the heavens would open and one could fall to my lap ...prefferably not in steel ..could do some damage to me!

[hugo carradini]

Hello fellows.
I find a forum www.mechmate.com that got me. My machine end up nice, but I wanted something more professional and stronger so I decide to tried making a Mechmate that with the nice and professional guide of Gerald D. I hope will be ready in a couple weeks. The good thing about the first 2 machines I build with the advice and tips you all gently gave me, is that I learned a lot about the basics and got basic experience. At the same time I had to move my shop and that was a lot of work that keep me away from the forum. Now I have to get up date with all the huge amount of new information that this great forum produces.
Glad to be back.
Regards to all.

Good to hear you are still around Hugo, also good to hear your plans for the next machine, make sure you post a log on this forum for us to see as well

Cheers.
