- In this video we'll take a look at the process of milling double-sided PCBs using Bantam Tools Desktop CNC. In this project, we'll make a breadboard adapter for the Adafruit Circuit Playground.

first time seen the simple way of making PCBs. Thanks for sharing this.
This is awesome! I loved this project and video. Now I want to learn more about making my own PCBs. Thanks for sharing
@Noe, sweet project and video. Thank you for sharing and inspiring!
Love this stuffff
Awesome!
Might you have idea to suggest how to cut blank PCB board to specified dimensions? Or is it simply best idea to order blanks pre cut?
Great video, nice.. Might be cool thing to have .. im doing some small stuff at the moment SMD so i have to go to CHINA to get things made :( i would like to make it in house as its costing a bit but still cheaper than buying from the Europe
Could we do the same with something like KiCAD and is there anything I would need to change besides adjusting for the mill's drill diameter?
Yes, You should, in the end, You need the Gerber files
Did you auto level before milling the board?
seems like they auto leveled the machine bed instead of the board, hence why they didnt get a full cut through.. lol
This is awesome. But on the Learn page, the Download links for the Eagle files (the adapter and the Eagle library) both give "Access Denied" when clicked.
thanks, we have the files on thingiverse now www.thingiverse.com/thing:2903619
Cheers, thanks! Great project
The fan part to blow dust, where I can find 3d model?

I was really excited until I realized none of those through holes are plated, so no vias
Easy to do.
@@legendfpv How so?
I don’t understand how this works. Isn’t that board just a complete piece of copper? So won’t that completed board be just one big price of metal in the end? What separates those milled sections from one another when the board is one big piece of copper?
They are blank double sided 'printed' circuit boards, check 1:56 (ie. there is an insulator layer between the two copper layers).
the board is not one big piece of copper its Fr2 material with a thin 1oz of copper layer on the bottom and top, like a sandwhich, the machine as you can SEE is cutting away the copper making the circuit and thus making some parts not touch each other.
Nice video, but missing feeds and speeds for cnc milling, maybe I missed it.
In the commentary he says the software does it automatically.
Too bad Bantam bought out the Othermill because it used to be affordable. :(
Z Deep? 0.05mm?
Speed? Mm/Min
Bit? 0.2mm 30°?
He says 1/32" flat end mill. That's just under 0.8mm.
I bought CNC from China on christmas, and since then i had a lot of problems with it.. actually i was never able to make a nice PCB, althrought i did make a working one, it wasn´t good. I really like the autoprobing and all this stuff from Othermill, but i am just not able to spend 10x more on hobby machine (i paid like 180€)... so, any1 have any tips how to deal with those chinese things? :)
Did you check if you have high spindle runout? That could ruin any CNC milling job that requires precision.
why double sided? one side pcb should work fine with this design.
Ever heard of proof of concept?
moooo
First!?
Lovely idea until you weigh up the cost of the machine + consumables (blanks are ~$2/sheet, 50ml of xylene coating is ~$15 for a 55ml bottle, bits need replacing after time at ~$25 each).. the cost/benefit compared to simply ordering factory-built PCBs just isn't there. That's on without all the vacuum time and isopropyl wiping and sticky-taping, and inevitable misalignments on early jobs.
The bits only cost $5 on AliExpress
*"...weigh up the costs..."*
Many makers have a lot of that gear for their workshops unless they are relatively poor but that tends to drive ingenuity. Many reasons why guys make their own PCBs.
Actually, the best use case is for rapid prototype development. You are right that OshPark or JLCPCB wil lget them done cheaper. But, they also take a couple of weeks for each spin. Being able to make a board in an hour is a pretty useful superpower in some situations.
