Stumbled accross this while looking at desktop CNC machines. The price is right at $460 for the kit. (Computer/software not included), but not sure of the quality. Anyone have thoughts on this unit? DIY Desktop CNC Machine Complete Kit | MyDIYCNC - Home of the DIY Desktop CNC Machine |

Looks interesting. Using a "Dremel" for the cutter. Small travel, ~9" x 6" which is just enough to do TVP's. Specs.... MyDIYCNC Desktop CNC Machine | MyDIYCNC - Home of the DIY Desktop CNC Machine For ~$500, interesting. |

| Re: My DIY CNC Save your money on the drill press. There is entirely to much flex in the whole unit. You can do some very rudimentary milling in delrin but you have to go very slow.

Hm, interesting looking machine! My 2 main concerns are: Dremels... awesome for RPM but start to load it up and... hellllo stall What are the upright parts made from? Hope it is something stiff like aluminum... That said if you got $500 to drop it isn't bad and with the demo of Mach 3 you can easily make small parts, just got to work around the 500 code line limit. There are bigger routers from Zenbot.com which i hear are nice... it just depends on what you can afford really |

The gantry supports don't have enough separation on the x-axis. Compared to a fixed gantry like the Microcarve Mv3 the whole unit looks pretty flimsy. Its also safe to assume the electronics are bottom of the bin.. the drivers dont appear to microstep at all. The steppers are small (nm17 size.. even taig conversions use nm23) Travels are right around micro-mill territory (actually a little smaller than the larger taig), and an actual mill is inherently more rigid.. Ultimately, i'd probably rather have a non-cnc taig or sherline. Get used to the mill, then add a gecko and some motors later. At the same time, theres nothing horribly wrong with the design, and it would likely do just fine-- provided you take it slow & are realistic about its abilities. Ive known a few people who built similar MDF based routers and have been very pleased. I also cant fault the price | |

Looks like they are decent for PCB's but probably nothing else...That thing would have a hard time putting a 1/8 end mill through delrin. The lead screws are threaded rod? What is the factory tolerance on that? I agree, I would rather have a manual mill (an actual mill) and convert it down the road. |

Thanks for the input guys. I was concerned about the Dremel cutting head. Guess I'll save up for a Taig. | |

I compared it against the Taig micro mill before making my at home cnc purchase, I ultimately chose the taig, because i'm personally weary of MDF construction. It has some advantages over the taig though. I believe he's using 5 pitch screws on the microcarve machines, which means higher speeds should be possible. The taig uses 20 pitch, which is great when manual (as it means fine accuracy) but becomes an encumberance on pc driven CNC's, as they cant reliably produce the step pulse stream fast enough to move the table around. | |
