Figure it would be beneficial for anyone wanting to build a DIY table to have some references to go by. I know it would help me experience newer CNC material. This is for the true DIY'er. Not so much turn-key "DIY" kits. I know some of us just have that itch to do everything ourselves. Foolish and expensive? Maybe. But, we just like it that way.
From my experience, Ebay is a decent source. Some retailers have stores on Ebay, already. I'm not endorsing or advertising. There's also going to be a lot of overlap since some of the website are CNC retailers of some sort.
- If you don't have access to metal fab equipment:
8020 - http://www.8020.net - Aluminum extrusions. Basically, expensive Legos for adults.
Linear motion and actuation
- Motion Contrained - http://www.motionconstrained.com - Domestic source for Hiwin linear rails.
CNC Router parts (CNCRP) - http://www.cncrouterparts.com -Boltable gear and racks and V-groove rails.
Moore Gears - http://www.mooregear.com/ - Great source for gear and rack setup
McMaster-Carr - http://www.mcmastercarr.com - Another source for gear, rack, LM, and all types of hardware.
Openbuilds - http://openbuildspartstore.com/ - V rail extrusions along with other CNC sources.
Motors and Drivers
- Stepper Online - http://omc-stepperonline.kancart.com/ - Found them on eBay. Imported and distributed in US. Plethora of steppers.
Teknic - http://www.teknic.com - BLDC "stepper killer" motors. Brilliant motors but expensive. I have these installed on my router table and they are awesome.
GeckoDrive - http://www.geckodrive.com - Great stepper drivers but expensive. G540 is a pretty common driver to use.
Leadshine - http://www.leadshine.com/ - More affordable stepper drivers
CNCRP - http://www.cncrouterparts.com - Nice steppers with molded DB25 cables and the Nema 23 frame has 0.375in shafts.
Controllers, THC, Ohmic, and anything related to electronics
- Smoothstepper - http://www.warp9td.com - USB and Ethernet motion controllers. If you want THC function, get the ESS!
Pokeys - http://www.poscope.com - Motion controllers with great BOB's and internal programming features. I have little experience with these but they are pretty neat.
CNC4PC - https://cnc4pc.com/ - Just a retailer of all sorts of CNC hardware: Smoothstepper, Pokeys, HIND, etc.
Proma Elektronica - http://proma-elektronika.com - Affordable THC. Works with Hypertherm's 0-7VDC CPC or other plasma units up to 300VDC (I believe).
Sparkfun - http://www.sparkfun.com - General hobby electronics. Switches, buttons, wires, passive components, etc.
Adafruit - http://www.adafruit.com - Same as Sparkfun.
Automation Direct - http://www.automationdirect.com - Great source for industrial grade electrical components.
Not sure on ohmic sensing. I know of Neuron but their website is corrupt and haven't seen any listings on Ebay lately.
Automated Technologies - https://www.automationtechnologiesinc.com/ - General CNC supply. They have it all!
Feel free to post to add to the list. Try to keep the format the same with a short description. Would be nicer if there was a way the admins could make this post free to edit.
