**Status**- Transformed .DFX files to solidworks 2009, thus creating functional 3D parts to create a digital working assembly. Tonight i will be ordering all the parts. I already found multiple laser shops and have received quotes.
**Possible Design Modifications**
Would like to modify the Sled to accept a 1HP mini palm router, or a 1hp mini laminate trimmer. Both how much more power then a Dremel, as well as accept a much larger range of bits.

I've completed 90% of the gantry, z-cart, z-sled, and base. Have all of the parts and hope to complete the build before the end of February.
Initially, I'm building it as designed, with the exceptions being the the use of baltic birch plywood and modification of the z-sled to accommodate the Dremel 300. Eventually, I'd like to redesign the z-sled to allow easy changing of the tool, to a higher power router or 3D print head.
I have everything about 80% assembled. I have noticed that adding washers to the assembly helps to shore everything up when using the PVC material. Gluing the parts together when possible is adding to make it very solid. Still sourcing someone to solder up my electronics kit though.
If you would like Amigaman i can assemble the board for you? I just finished soldering up my board tonight takes about a solid hour. you pay shipping both ways and throw in a 10 dollar bill for solder, and pcb cleaner and i can solder it same day and send it on back! :)
DIYengineer. Sounds great to me. Can you send your contact info to andyman61533 at yahoo.com ?
Contact info sent!
Update: I have all the parts except the Transformer (should be here tomorrow), and today i will hopefully hear back from the laser shop so i can either pick up 4x8 sheet of Masonite or MDF. Then i will use a micrometer on it and adjust all the files accordingly. I also am making a custom electronics holder for the board instead of using the supplied lasercut one. I would use the pre-supplied one but i don't have it and i want to start and knock it out tonight.
Aye! I'm finally doing it. Got all of the parts in hand. I'll be the first test to see if the average idiot can pull this off. I do have the advantage of working across the hall from Taylor and Chris so I will be testing their patience and customer service skills. I just got done assembling the driver board short of the chips. I'm hesitant to install them because I can't seem to get a 12V reading from the transformer. I'm using the recommended one from MPJA.com. Reason being, the mpja one has 2 black leads and 2 red leads coming in on the 120V side and 2 blue and 1 yellow lead on the 12V side. HobbyCNC instructions indicate to connect the fused wall outlet to the two black leads and output from the two green (12V) ones. Anyone know how I interpret HobbyCNC's instructions given the difference in lead color and quantities?
All that aside, my girlfriend and I are excited to have a CNC in our home. Maybe CNC parties? At least now I'll be able to run G-code files while watching TV in my underwear, and for that Chris and Taylor, I salute you!
I'll try and keep updating.
Keep in mind that the transformer has alternating current at the input (110VAC) and the output (varies). When presented with three leads at the output, you should have two same-color wires and one oddball. Take an AC volt reading with a multimeter off of the two same-color wires and you'll get the full output of the trannie. Combine the oddball with either of the same-color wires to access the center-tap, which should give you half of the voltage from the first test.
The HobbyCNC board can accept a wide range of voltages (12-48 if I recall). Remember that this must be direct current (DC). Reread the documentation and make sure that your output falls within the safety zone (rather than trying to match any specific number).
Feel free to drop by the lab if you're still confused.
Nice Conrats! More the merrier.
Update: 100% done with the controller box! Waiting on a few more quotes from local laser shops! I Then just have too send off the .DFX files to get cut! I have all the hardware and parts as well. EXCITING! Also have Mastercam X3 and Mach3! I cant wait!
In regards to Post *10*: If you use a MPJA it has 4 primary wires, Black(A),Red(A)/Black(B) Red(B). Solder the like colored wires together (RED A + RED B) (BLACK A + BLACK B). The Triad brand that hobby cnc uses in the instructions only has a BLACK, BLACK (2 wire primary setup opposed to 4 wire). By connecting the MPJA's like colored wires you now have a 2 wire primary setup and can continue on with the instructions. The secondaries have 3 wires, 2 of which are the same color. The 3rd wire that doesn't match the others is not used, simply bend that wire back and seal it off.
As i was following the instructions it kind of threw me off, hopefully that helps others.
Thanks DIYengineer!
(MPJA transformer)I also learned that the transformers secondaries are 24volts as advertised, but when you pass it through the rectifier, it multiplies the voltage by roughly a factor of 1.41 giving you roughly anywhere from 32-34 volts @ TB6 (your main inputs for the hobby cnc board). I thought i did something wrong, because i was looking for the 24volts, but i contacted Dave over @ Hobby CNC and he verified that it was correct. =) So don't be alarmed! You did it correct! The board handles 12-42Volts DC input!
Update!!! OK so i finally got the ball moving with this thing. driver board is assembled and wired up and case mounted. Started the laser cut panel build last night and was half way through in just 2.5 hours, but then...i ran out of screws. the list calls for 1 box 100ct. of .75 machine screws, but i'm thinking it needs more like 150-200. seeing how i ran out so quickly. other than that, smooth sailing. check out my pictures! i still have to read through the 100+ page mach3 config manual though. meh.
