CNC Motion Control with LinuxCNC + Mesa FPGA Card

[@frosty129]

I know very few people on this planet who can single-handedly build an industrial grade CNC machine from scratch, being the electrical engineer, the mechanical engineer, the software engineer, and the product designer all at the same time. This takes DIY and creativity to another dimension.

[@andypughtube]

Odd, nearly everyone I know can do it :-)

[@frosty129]

@@andypughtube I guess I need new friends

[@andypughtube]

@@frosty129 It's more that after 10 years working with LinuxCNC all the normal folk I know have abandoned me. :-)

[@tamurhaq]

@@andypughtube I think the point is that Marco clearly takes it to the next level. Most people just slap together controllers and software and watch it go. This level of calibration and tweaking is very rare. Especially calibrating and pid tuning fpga controllers for cnc? I dont think I've seen another video on that to be honest

I've never simultaneously been so much intrigued and entertained. Still one of my favorite channels. Thank you

[@SaNjA2659]

The I term in PID not only affects the reaction speed of the system, but also ensures error is being zeroed-out over time. Without it the error, however small it might become thanks to high P gain, will always remain there.

[@heronguarezi6501]

You are a genius. I retrofitted a couple of 5kW servomotors a while back and they always shoke a bit. Today I opened the motors and wrapped aluminium tape around everything. The results were impressive, not very pretty, but Impressive none of the less.

[@kal9001]

This project is looking even more hilariously expensive with every new video!! Awesome though!!

[@nochan99]

"surprise reboot" I am suprised that one isnt more common xD

[@GlennHamblin]

I thought that was a standard feature of Microsoft operating systems.

Hey, I recognize that enclosure, that is a Rittal, they make great stuff, we use them in our designs at work quite a bit.

[@heronguarezi6501]

U are the best!!! I started to use the mesa 7i76e, and I am now inplemententing the feedback from the linear scales to linuxCNC for a HELLER BEA 2

[@OriginalJetForMe]

My computer is a PC in a regular enclosure that's connected to a Mesa 7i76e card over Ethernet. The 7i76e has an RS-485/422 port on it, but it's currently only used to communicate with Mesa daughter cards. I want to reconfigure that to communicate with my VFD for spindle control, so I don't have to run a separate RS-485 cable from the PC to the controls cabinet.

[@namAehT]

You should check out Klipper for your printers. Basically, a Raspberry Pi does all the gcode translation and kinematics, and then sends scheduled movement commands to a microcontroller for real-time execution.

[@LatheBuilder]

"We're certainly not inching over here" - gold!

[@kevinfontanari]

"Surprise reboot" sounds like a really useful bios feature...

[@bashaaksema94]

Congrats on the 100K subs btw dude!

[@Lagggerengineering]

I would appreciate a guide on how to set up and then use LinuxCNC. It can get a little complicated.

[@n0madfernan257]

saw the hanging drive at @6:30. nonetheless, great job and congrats for the youtube package

[@gabiold]

Do not ignore the I term in PID! It compensates error over time, but that does not mean long term drift. It is timed in PID cycle time, which is (should be) very fast compared to "long" in human sense and fast enough to keep up with the movements. Without the I term there will be always error in the position. As you approach the destionation the error will gets smaller and smaller and while the P-term is just a multiplier so is the output. It asymptotically converges to zero, would require infinite time to reach it. In theory. In practice the friction stops it before. The I-term roughly works like "buffering" the error while you moving to the destination. Then it will "lengthen" the output where the P term starts to get ineffective. Vaguely... Obviously it is a continuous function, but it is hard to imagine that way...

[@ZacksLab]

Congrats on 100k! Your channel and content is inspiring!

[@Seegalgalguntijak]

Glückwunsch zu den hunderttausend! Der Kanal ist es definitiv wert, aber ich hätte nicht gedacht, dass das so schnell geht - vor allem, weil es ja doch eher "Nischenthemen" sind. Aber auch wenn man die Videos nur wegen des Humors anschaut, sind sie bereits äußerst sehenswert :-)

[@heikofirestormtiger4969]

Glorreiche Glückwünsche für die 100tsd Marco!

Pneumatic tool changing on that spindle?! Awesome!

[@noddingat]

Yeah I want to know more about that!

[@giovannibianchessi1578]

Thanks for the video. Board 6i24 configured as 5i24, right? Feed forward helps a lot to reduce following error in axes tuning. Trying to keep following error =0 often makes axes nervous. The important thing is that error has to be the same for all the interpolating axes.

[@imabeapirate]

The PCIe custom riser cable tho...

[@chemicalvamp]

Marco, Every new video is enlightening. Thank you for doing what you do.

[@nicholasjacob3594]

Marco, how intensive is linux cnc, how striped down is your computer does it still have the full 8gb of ram or did you take out that to cause ram is overrated. Also is the computer maxing out doing these jobs or is it over kill.

[@reps]

this particular PC with i5 is an overkill for sure! 4gb ram is plenty.

[@nicholasjacob3594]

Thanks a lot this is very helpful

[@kwinzman]

2:45 Dungeon Keeper sound effect? :D

[@AppliedMetaphysician]

Proofs-of-Concept are seldom very pretty. :)

[@ts2wv]

Like some other commenters have pointed out the I term is usually very important and it's the D term that's usually ignored...

[@AdaptivePhenix]

That depends on how your servo drive is configured. If your motion command is a velocity reference then yes but if you are commanding current (torque), you will absolutely need the D term. In my case, the D term ends up at least an order of magnitude of the P.

[@Joemama555]

nice turbo molecular pump spindle there... does it have a coat too, where is it? seems chilly in space without atoms...

Ah, Vogel Zentralschmierung :-) I know Mr. Vogel personally. Nice to see their products at your nice machine :-)

[@LanceThumping]

On the 3D printer accuracy front, have you checked out Klipper? I would think it would solve a lot of issues since it does most of the brain work so that the controller can focus on properly commanding the steppers.

[@arthurdent8091]

Hi from the USA. I have been following your posts for quite some time. I particularily like your dry sence of humor sprinkled in with the narative. You have answered a question for me. I have a 3018 Pro and I wanted to know if I could control it with a Pi4; this episode has told me NO, so thanks and please keep posting.

[@小健-w1k]

[@MXstar189]

did we look at mach3 at all i was under the impression that was the go too for the home/custom cnc stuff

[@britzwickit]

great video, makes the entry into linuxcnc much less daunting

[@amessman]

3:27 I'm not sure what CPU you're using in the computer but the heatsink should probably have a fan, and maybe some cutouts in the case for ventilation. IIRC those heatsinks use 60mm case fans and M3 screws [haven't watched the whole video, maybe you puts one on]

[@DreitTheDarkDragon]

Now I need that card and somebody who will make mod for Euro Truck Simulator 2, so I could plug all possible inputs and outputs (steering wheel, pedals, dashboard, pneumatic chair,...)

Nice overview and good work. I was surprised a few years ago when I found Mesa Controls was located near my house. Not often can you check the "will call" button when buying stuff on the web, and no Customs Inspectors to worry about. Great hardware too. :)

[@franke5478]

9:20 You use an FPGA card reading the ecnoder values while you drive the motor and you have to find the correct values until the error is nearly "0"? Sounds like the Mesa card doesn't work as a closed loop system - but it should be! A closed loop system detects the missing steps from the encoder while it drives and corects the missing steps in the end.

[@tokarka8258]

Hi! I'm recently decided to move up from Mach3 to Linuxcnc my 2 cnc milling mashines, but there is the problem with one of them. It has kinematic system with moving X/Y by the table and spindle moves jus in Z axis. How did u described to linuxcnc cinematic of yours mashine? If i change direction of movement in INI file there is a gap between actual movements and linuxcnc program coordinate system. If i switching all preferences to cooperate program coordinate system with actual movement my keyboards hotkeys works in opposite side ("=>" key means "X-", "

[@stheil]

Oh that remote is just gorgeous! I don't even have my own CNC machine but I want one of those XD

[@emperorSbraz]

current monitoring is a good way to avoid pushing tools beyond what makes them crack easy.

[@jackbacic868]

I made the bits for H&H finishing the machine takes a lot of work but those ultras 5 axis machines fly.

[@bmg1612]

Your pendant looks awesome (7:24)! Where did you get it?

[@KarlMiller]

Thank you so much for putting some context around the Mesa card on linuxcnc. Trying to get a handle on how these pci controllers work with linuxcnc is a little bit overwhelming if you just try to read the Linuxcnc forum pages. Question : if you were using steppers and stepper drivers like geckodrive's, but still needing the same amount of relays and controls over water cooling pumps, and the VFD and sensors, would you still choose ; 1. To use linuxcnc over something like Mach3 ? 2. To use pci type motion controllers instead of parallel port or USB external boards?

[@InXLsisDeo]

Cool little speakers, did you build them yourself ?

Hello Marco, can a single 5I24-16 run three linear encoders, mpg, 4 step/dir servos, 6 end switches, vfd ? can you use normal optoisolated breakoutboards?

[@IVAN_ENT]

So interesting I build and fly fpv drones and want to build a mill eventually, you have to tune pid's in betaflight software too

That PID running sounds complicated! I presume custom tuning is not needed for the steppers that have built in driver and feedback system?

[@jcims]

Do you have any issues with cogging of the servo motors in this setup? Just given how rigid the whole thing is I'm curious if they get damped out or if you can get things ringing with a specific axis moving at certain speeds? (Or maybe the servos are nice enough to either compensate or just not have that much cogging torque).

[@davidgadea4345]

Nice MPG. Hope to see a video on the set up. Where did you get it?
