Hi all, RBrochey live from the last bit of physical therapy before I can get back to building. I was wondering if anyone could tell me what would be a good entry (simple) CNC set up would be, I know about zero and want to learn how to do it. I've seen all kinds of cool little set ups out there but end up more confused!!!

Thanks!!!!!

I started with a CNC setup called a Lowrider2. It was cheap, but DO NOT be lured into this.

I spent some modest money, and bought one of the Openbuilds models - A Workbee 1500 x 1500. You're in New Mexico, so the best place to try is WorkBee Version 2.2 CNC Machine - 1500 x 1500mm - Maker Store USA

I am the community maker space Although I haven't told anybody cause I know what will happen... I so wish there was a $4/hr shop with everybody else's stuff that I could just go use. One person always spoils those sorts of things for everyone else.

While there's some differences hogging rough cuts with a 3/8"+ bit, most of the finer points you can learn on a smaller one... Then decide if you need/want the bigger one as you learn.

Just be careful of the software a lot of it is loaded with Malware. I have one of the 3018's little brothers & all of the software you find for it from China has "Interesting software" included free of charge. There's good software avaalable on github & the Facebook group is good as well

Yeah, applies to pretty much all the chinese products... 3d printers, the little lasers, the CNCs... Most of the time you can do 100000x better than the software supplied.

You can design, build and run any CNC using open source software, Freecad for design, Arduino GRBL for post processing, UGS universal gcode sender. Gcode can be generated from Inkscape or Freecad.
Airfoil .dat files can be imported into Freecad and gcode generated from the Path Workbench.
I have only purchased one software program, that is Estlcam, it allows the generation of Gcode from complex 3D .STL files so you can machine double sided things like this.

And not have to deal with Malware

I entered cnc one and a half year ago, it took me 2 days of training and a couple of months of probing but was OK... now I can't say I am a pro cnc machiniste of course but I did many things for my gyro .

but I was really lucky to find the right teacher who sold me a chinses cnc he had prepared to work straight away .. and I did litterally tens and tens of parts .

if I had had to start from zero and discover all myself ... I would have given up

definitely the soft you have to use is fusion360, you have all in it you can model and also manufacture ( generate the G code for the cnc),

there are so many tutorial in english that you can learn all by yourself ( at least as for the design module) for the manufacture module it is a bit more complicated to learnt this by yourself , but ok I could show you the basics

Hello All, I agree with Vigilant1 that a co-op "Makerspace" is a viable alternative. These are usually connected to Colleges and Universities with Community involvement programs. In my area RPI developed such a space in Troy, NY that I was able to "buy" an expert's assistance. I could have joined the makerspace and done it myself but for 2 4x8 sheets of ply it was less time consuming to buy expert assistance. I have attached a couple pictures of what the CNC instructor did with (another Volksplane builder's - most of you probably know him) provided files.
