This is the story of my progression from the JGRO cnc router design to using the OpenBuild system. In the process I think I have learned some. Steps for: Build a home made CNC machine (JGRO router). Step 1. Step 2. Step 3. Step 4. JGro CNC router from Stock setup. There is an error in the Z axis assembly – the fixed section holding the tubes on which the slide moves is too.

Besides cutting wings, I’ve had equal fun cutting foam art. Used a pair of oillite flanged bearings in a loose fit hole, the flange is recessed and trapped by the pair of fender washers. They cut both the top and bottom half side, by side.

They went together easy, cutting the components with the table saw. Well Dave, you jggo making great progress.

I cut that foam trophy for him and will present it to him on Tuesday. You can’t turn a complex airfoil on Now if I were cutting a foil for a mold, then no problem, because you would cut a top, the cut a separate bottom.


See the example below. Found the driver chips igro poor solder joints not enough heat I guess. Skip to main content.

Hi Dave, I’ll be watching your progress on this thread. Too many Routeer also.

As well as the machine you will need a computer with CAD computer aided gouter and CAM computer aided manufacturing software as well as a program to drive the CNC machine.

I’m leaning toward a stressed frame on the back and triangular bracing on the top of the gantry.

Gerry you just pointed out what those ads do not tell you. I appreciate the heads up about the dimension changes. Last edited by carlnpa; at This project describes how to make a CNC oruter numerical control machine that could be used to make guitar parts.

The expierence and insight will surley be a big help. See the attached picture.

Forum Information and Options. CNC level of difficulty: Thanks for the tip about CamBam. There is no noticable free play in the coupling, the spider is a tight fit in the hubs. Changing X-axis envelope during What is a Digitizing Tablet? Good luck with you build. I wanted to show the assembly before I buried it by putting the machine back together.


Digitizing can be point to point, continuous curves, freehand drawing, lines, arcs, circles, and curve fitting between points.

JGRO router is functional – The Hell Ya Beller

Too bad though, this CNC router project is putting a big delay into those build plans. By the way, John is a far better craftsman then I, so we can expect a higher grade jgrk work from him.

One outer edge will have to be routter down to clear the gantry floor. Hi Sabo CNCzone is the definitely the place to go for the best advice. I tried some other springs but these seem to work best on the compromise of increased rod friction vs movement, still very free movement.
