Last bit of parts!!! 04/22/2010
The last package of components arrived yesterday! Pretty exciting. I haven't really thought about the CNC over the time I've been waiting for the parts to get off backorder so I'm ready to get back to work. I still need to order some solder paste and pick up an electric skillet. I've checked around at the local thrift shops to see if anyone had one but I haven't found one. WalMart and Target both have one for about $20 so ill just pick one up from there. Finals are coming up so don't expect to see a huge amount of progress! On a similar note I talked to Ed over at EdsLifeDaily and he's found a new driver design that he's testing out. Make sure to check it out. That's all for now but Ill be sure to get to cookin on those PCBs in the next month.

Yeah! It took 2 weeks and a trip to the local FedEx to get these puppies but they look great. I have more of them than I need so if any one needs a couple, hit me up and Ill sell them to you. Im going to put a couple up on eBay to see how they do. Ive still got about 12 LEDs on back order at Mouser so its still a waiting game. Its always nice to get stuff in the mail though. Ive got a couple more things to gather before Im ready to assemble. Solder paste and a hot plate. i went by Goodwill to see if they had el cheapo hot plates...They dont but thats cool. Target has them for like 20 bucks.
I posted 9 in the ebay listing last night and sold 3 soon after posting. I also got a request to ship three to Canada so it looks like I might recoup some of the money I lost having to order so many. Heres the ebay link for those interested in ordering.
RepRap Stepper Driver V2.3 PCB
Now we hurry up and wait. 02/25/2010
Latest news in my quest to finish up the CNC is that I've placed the order for the PCBs. I had to order 21 of them to meet the minimum order but Id rather have done that than to have paid 70 bucks for just 4 of them. It turned out to be close to 140 shipped with a 2 week turn around. I figure I can put a couple up for sale on ebay and connect with people looking to build their own RepRap. In my opinion its cool what the RepRap team is doing but its abit unstructured. For the average builder, not being able to acquire the stepper drivers or the bare PCBs to make them would be a dead end. Especially if they looked around and found out how much it would cost to have them made.
Head on over to Edward Fords page and check out his project CNC. Ill be looking into the software side of what he has dug up when I start pulling my electronics together and testing them.
Started the Ball Rolling 02/16/2010
Ok, I took the first step. I thought I had sourced everything to make the Reprap driver boards. I ordered all but one part from Mouser (11.58) and the driver came from Digikey (5.81). I ordered four sets of components so I could have enough to have one as a spare. Then I went to order the PCBs. MakerBot used to have the whole board assembled and everything for 30 bucks a piece but thats been discontinued. They used to have the bare PCB as well in this nifty red but it as well had been discontinued. I found another site selling the bare PCB but it turned out to be discontinued there as well. So I spent the spare moments of the day looking into "fab houses" (places that make bare PCBs). Sparkfun has one that comes out to be close to $70 for three boards and I found a larger company that could make 12 for not much more than that. Im pretty sure that Im going to bite the bullet and get the 12 and either sell them on ebay or on here if any one is interested. A parts list can be found in the Reprap link I posted in my last post. The drivers are run off of a computer PSU and can run up to a 2A motor. Just so everyone knows, I didnt design this circuit. Props to the Reprap community for all they have accomplished for the open source community.
