- Some things I learned over the first couple of months assembling and using my new CNC router from CNC Router Parts.
Links to a few items mentioned in the video:

1" HDPE sheet - amzn.to/2Dkjp8C
Info on the spoilboard I use: www.cncrouterpa...
Dust shoe info and plans - www.cncrouterpa...
Also other useful stuff for the CNC router

Just found your channel and have been doing a deep dive on it. Really great stuff. Sorry to see you haven't been active for a couple of years. YT is fickle and usually pushes crap content over the good stuff. Anyways, thanks for the vids and hope to see you back some time. Subscribed (FWIW).
I appreciate your kind words! I do plan on getting back to doing videos in the not too far future.
@@ChappysGarage Glad to hear it. Your Fusion360 from cradle to CNCtable series is exceptional.
Enjoyed the video, looking forward to seeing more.
What size table do you recommend? Since you said it should be smaller than the footprint? Great video!
im a little late but what are the total parts that you need to get this working? like of coarse you need the kit, but like do you need to get anything additional? good video!
I believe you could buy everything but the things I added myself were: the table (you can buy a leg kit that mounts to the frame but much cheaper to make a table), the router (I used an old Porter Cable router I already owned), a PC to run the software (again, an older one I already owned), a sheet of MDF for the spoil board. And of course you need some form of clamps to hold things down which I made some that bolt to the table via threaded inserts (I have a 3-part series where I do that starting from the fusion 360 design all the way to cutting the part). Hope this helps, thanks for watching!
@@ChappysGarage thanks! that really helped, i am ordering one later this month and just needed to know what i was getting myself into lol.
If you're going to get a spindle, buy a water-cooled version. You won't regret it. 2.2kw spindle is miles better than any router you could find. Not to mention its easier on the ears. at 10k rpm its practically silent and at 24k RPM you can have a conversation without straining to hear. Also, you won't be blowing around dust with an air cooled spindle.
Those grease nipples are a real pain! I was careful not to over tighten during assembly but nevertheless over time they eventually work loose when wrestling to free the gun from the nipple. Coincidentally I just manufactured new end caps for the bearing units last week from 4mm aluminum and reinstalled them with a silicone gasket cut from reusable food storage bags. So far the modification is working great though in hindsight I might have opted for 4mm mild steel. Happy to share fusion file with anyone interested in making the modification for themselves, ping me a mail @ info@digifabcnc.com!🤓
Great Video! Are you happy with the nema 23 motors?
They have worked fine for me so far but I am still using the normal woodworking router as a spindle. Possibly when I upgrade to a more powerful spindle I might want to push it harder and might need the bigger steppers, but so far certainly no issues.
I use nema 23 on my 4 x 8 foot home built cnc - much heavier than this one and they can rapid at about 600 IPM pretty easily and I've cut things up to 250 ipm using a 2.2 KW spindle. Plenty fast. I feel like the Nema 34's would be nice however, I would think that they would only be mostly an improvement if you have a vacuum table with a quality pump and just higher rapids which on a bigger table is a huge benefit. As to cutting things, you're mostly limited by the weight of your gantry, and the size of your spindle. In my opinion anyway.
I run an industrial router at work and it seems the speeds are mostly limited by the hold-down system in place. Ours uses suction cups and that induces a lot more vibration. Vibration is your killer. More vibration you have, the faster your bits get worn down, overheated, and therefore one has to lower their feed rate.
In most cases no one will ever cut at the speeds the motors can actually move at. Machines this small anyway. Last CNC router I've used cut at about 1000 IPM but the thing weighs about 25000 pounds.
@@LogicSpeaks Thanks for taking the time to share this info, very helpful.
Great video, thanks! What size would you build a new table? I'm getting ready to order a machine like yours and would prefer to build my own table. Actually a good friend will build it for me as I am disabled now and have only 1 good hand. Do you find the wooden table to be RIGID enough or did you have to add a little extra bracing? You pointed out several things here that I would not have thought of.
Glad I found you and this review!!!! Subscibed!!!
Is your Avid cnc for sale?
stupid question ! any reason why you used your own router ? given the fact it has brushes VS an air cooled spindle ?
Just to save a few bucks but I recently replaced it with a much better water cooled VFD spindle. Bearings in the router had gotten worn causing a lot of deflection over time.
Which model of Porter Cable router are you using? Satisfied? Thanks.
It is a model 690 which I used just because I had it on hand. It works OK, very loud and not overly powerful. I plan on upgrading to a proper VFD spindle at some point but have not had any real issues with it as is.
