Hi guys, I know you love pictures so here are some of my mill and the cabinet I built to house it and the controler. The cab is just finished and cut noise level quite a bit.
The cabinet is 3 x 4 x 6 high made from 5/8" MDF. Its heavy!!! So to move it around it has 4 wheels rated at 300 pounds each. Heck I can get into it no problem but i'm 150 pounds only...
The window is 2 layers of 1/8" Plexyglass for a total of 1/4" thick. That is what I had on hand, but will probably add a layer of 3/16" lexan on the viewer side. Any tought on this issue? Is it safe enough? I mainly cut wood, plastics and engrave stuff. No aluminum cutting here but maybe some engraving in alu or brass.
As for the machine, it's my first one fited with 1/2-10 ACME lead screws on the x an y and 5/16 All thread for the Z. All parts of the Z and X carriage as well as the Y table will be replaced with aluminum cast parts. Some are ready, other I must first mill the patterns. All in all, I get a good 18 x 12 x 3 in the current config.
The spindle is a 5A dewalt laminate trimer with up to 30,000 RPM capability. It also has air spindle cooling using an airbrush compressor to blow air on the lower bearing area. I use a dremel speed controler which can be seen under the computer screen.
I found a computer AC plug/switch box to plug it all together, which is just under the screen there. I dream of a flat screen on a pivot on the side of the cabinet... eh, maybe some day...
This machine will soon have 3977 drivers as found on the PMINMO site. I bought a couple of the blank PCB and got my Allegro samples. Just have to build em. Should reach around 20 IPM with those drivers.
Next step is a JGRO style machine, that'll fit tight inside the cabinet. Fixed gantry + 4th axis would be great...
Also pictured, as a bonus, is the atlas mill I am rebuilding to make it cnc, but that's another story.
This has been possible thank to all who posted here before me. So if you have questions, go ahead, ask.
