Bluumax CNC router kit $415.00 with motors and controller
 
My cnc router kit arrives tomorrow from bluumax.com. This is basically a diy kit that takes the engineering out of the equation and allows a person to concentrate on the other aspects of setting up a cnc. I'll post.

Router arrived. Yea this is my first router. I'm in school learning g code and setup. I have no affiliation with bluumax.

I have everything assembled that came with the kit and added wood, threaded rod, a power supply, and some wire. I have a smoothstepper board in route via overnight to address the mach 3/Windows 7x64 issue.

Let us know how it runs when you have it all together. I would like to build one for home since i have 4 large CNC machines for work that i use everyday.

I have the smoothstepper now but had to make another order for its special cord that adapts the parallel to a 26 pin low profile, and I went priority on the shipping this time so it will be a few days. I have been learning the basics on various Haas equipment and I'm sure the bluumax won't compare, but I'll let you know how this works out for the money. The build was crisp with everything being tapped with perfect placement.

I will eventually use it to cut parts to upgrade it. It would be cool to see one with acrylic b and c axis milling a compressor wheel in foam or plastic.

Geo, Looks great. awesome job of gettting it up and running. Do you think the plexy side supports will be enough for the router running and the side loads that will be put onto the cutter? Can not wait until we see wood chips.

Keep on building

I saw where a person added a piece of plexy parallel to the x axis and attached them to the side supports of the gantry to box it up and add strength. I found myself buying a 1/4 trim router to mount to the bluumax, which has also been done, and I think letting the tool do the work is going to be the name of the game. The Bluumax website does suggest that mods are a likely occurance once the basics are covered, but I just want to cut battery trays out of ply and shape foam for composite plugs so the Max is a shoe-in for cost effectiveness. I'll post once I get the spindle mounted and ripping!

So I cut a piece of melamine a few times because it was the only material I had on hand. It cut really nice at 60ipm but I lost steps and slowed it to 5ipm. The cuts tend to heat the tool at that rate of feed. I was also having trouble keeping my work peice down and it would jump up into the tool at times. Without calculation it seems I may need to find a middle ground for my feed rate and maybe continue tuning my motors.

There was talk of changing the steps of the motors to increase torque. They are at half step now and I am not sure which setting would give more torque,1/4 or full step. The 1/4" tool is alot for this machine and it results in very high cutting speed and alot of side forces to contend with. I believe the 1/8" tool it was designed for will cut down on cutting speed and take less torque from the steppers to move accurately.

I think the cutting speed was way high in the video and that is why the tool never got sufficient bite and instead created heat.

The bluumax Y linear motion is held in place by gravity. I may begin a mod in this area by simply adding some wieght to it at a low CG.

With the proper feeds and speeds, tooling, and depth of cut, the bluumax performs! It says on the web site that the bluumax is no race car or tank, but when used within a nominal level of load it is very useful. It seemed to jump to life after I lubed the lead screws with silicone grease. I also added 15lbs of pennys to the gantry below the cut table.

I have been learning MasterCam. Bluumax is good for learning. Everything cut with .125 straight flute carbide from Home Depot. 50% stepover on the facing.

Looking good. Once you start with any type of machine, whether it's big dollars or not... you learn how incredibly simple these things really are. They look scary and intimidating at first but the fears go away quickly.

Small and inexpensive machines can be extremely useful, just not usually extremely fast. Enjoy your first machine, and use it to make your second machine... like I did.

Yeah, the first one has got to be the first one, and I am starting to get a grip on Cam software as well. Making a new router in the future is inevitable once I am proficient in 3d modeling. I am going to make some foamies and test out some designs. When I get one I really like I will scale up the Cad File and the router and use the part as a plug to make molds from!
