Milling 6061 Aluminum Plate on a PrintNC CNC Machine

- In this video, I demonstrate how a PrintNC CNC machine can easily mill 6061 aluminum plates. These new parts will be used for improvements on the machine itself. Watch as the machine efficiently cuts through the aluminum, with me providing commentary throughout.

videos like this make me keep coming back to the PrintNC as my first DIY build
absolutely AMAZING
Great Video thanks I can't believe the finish you are getting with the wooden Z axis plate can't wait to see your new Z axis assemble in action please keep the videos coming
beautiful man!
Amazing ide mr😂😂❤❤👍👍👍💯💯💯
Beautiful parts! Are those closed-loop steppers on your machine, and which controller/drivers are you using?
I can't remember if I was using stepper motors or servos for this. Early on in the build of my machine I found at the stepper motor drivers were all crap, so I switched to some powerful servos.
I drive everything with a Mesa 7i76e being controlled by LinuxCNC
Hey Bryan, what is the dimensions of your CNC work area.
Just trying to get a final size for my build.
The table enclosure is 65” x 50” and 70” tall. Work area will be changing but currently it’s 900mm x 550mm x 125mm
Thats some Fast pecking :)
Never had good results with 1 flute. But maybe it was my fault... only bought one type/brand right in the beginning of my learning curve cutting "loominum". Since those horrible cuts, always been using 2 flute.
They are stronger for bigger feeds and also clear chips really good (even cutting dry as I do)
Give it a try Bryan 😉👍🏼
I’ll give them a try. I have a bunch of endmills waiting that I haven’t used due to the limits of my plywood z head. A bunch of 3 flute in 4,6,7mm. The degree of spiral on them should make them run much quieter than the single. I’ve got a BAP that takes 8mm round inserts but z head isn’t rigid enough to make it work.
I cut the second skinny side part today dry which worked out better. Air blasting dry chips clears them well. I haven’t tried but I can’t see how MQL would work all that well. Like you get the chips just sticky enough to get stuck then you end re milling them all and heating everything up in the process.

Yeah, I also have a 50mm BAP400R and also got to work my gantry a little bit more to use it properly.
Keep the updates coming please... :)
ive found that single flute provides better chip evacuation for aluminum and prevents chip welding much better than double flute. to each their own i guess
Given the physical limitations of the PrintNC, the router spindles can't be slowed down enough for the correct chip load with a two flute endmill, unless you're only using 1/16" or smaller.
Quick question, do the chips ever get into your linear rails or ballscrews? Have you seen any performance issue because of this if at all? thanks
Yes they do get in the rails and the ball screw, if the are greased, then the chips stick to them. In my case I get powdery chips mixed with coolant oil, so the whole thing turns to muck. So I have to clean the rails and ball screws after every major job. I find that it’s mostly surfacing operation that throws stuff around.
I am thinking of putting plastic curtains mounted on the X,y and z axis. When the gantry moves it draws the curtains along thus protecting the rails .
Great video! Just curious, what software you using? I've been using Mach4, but honestly, I'd like to switch to something better.
I'm using LinuxCNC. It's very robust. Never crashes or does something unexpected. Runs in a real-time version of linux on the operating system so there is no latency when pressing a button to jog the machine. Everything happens by design is realtime.
I'm using QtDragon HD as the front-end for linuxcnc but there are also other good ones such as Probe Basic.
LinuxCNC is far more work to setup due to it needing a specific realtime operating system but I think it's worth it once you get it running.
If you're doing anything non-standard with controlling the CNC you can remotely drive LinuxCNC with Python programming language too. See the laser level Short's I put on youtube about that.
@@BryanHoward Awesome, thank you! I'll have to give it a try.
Spindle power?
2.2KW @ 220V
this could be my future CNC, now I building LR3 (Lowrider3)
0:47 I thought something insane happened but it's just video image distortion :D
tape (or magnet) carbord "shields" to the sidebeams, to deflect chips from the rails and screws maybe? until you have time to properly protect them... alu is nasty :)
Yeah I gotta do something. I’m going to clean out and regrease/ rebuild the bearing blocks when I disassemble the Z head. I’ve even thought about what it would take to make some stainless steel telescopic covers for X and Y out of 22ga or thinner 304 stainless sheets.
going too slow on the slotting, look how thin those chips are.
Old video when the machine was not very capable.
pecking fast and long
Love the servos too. Well done machine is nice and the love is visible.
without feed and speed and tool details its not useful !!!
Trust me, you wouldn't want to use the f&s anyway as I didn't have a good handle on it. See my later videos if you are looking for such things. Better to just calculate it for your own tooling based on chip load
Your peck drilling need some improvement
