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

[@rockybass3129]

@@andypughtube Yeah but still that first EMC or Mach, fully ballscrew converted Rong Fu retrofit cnc is still a milestone.

[@izidor9199]

You are a master, i mainten and repair CNC machines in a factory, also build myself a cnc router. Watching your videos i can only think what a pleasure and honor it would be to work and learn from you. Hands down the best chanel on youtube for me.

[@matiasgoinheix366]

What's your balls crew maintenance workflow?

[@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.

[@nochan99]

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

[@GlennHamblin]

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

[@matthyslaubscher8151]

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

[@kal9001]

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

[@paco3447]

I think that amazing CNC deserves a vacuum table as a good update to clamps.

[@jennimorgan394]

Best unboxing ever. I thoroughly enjoy your sense of humor.

[@matyk985]

WOW, I think that the is one of the most ambitious project yet, really nice work and you are flying through the progress.Nice, good look in future !

[@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

+1 for Mesa FPGA addin cards and LinuxCNC combo. Converted our vmc with them, wouldn't ever want to go back

[@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,...)

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.

[@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.

[@Lagggerengineering]

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

[@emperorSbraz]

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

[@chrisbartrum3201]

Kuddelmuddel gelöst. Glückwunsch Stefan.

[@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 :-)

[@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...

[@SimoWill75]

AvE style unboxing. Nice.

[@voltlog]

Yet another awesome video 👍

[@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.

[@imabeapirate]

[@TheHibener]

Honestly, i have no idea what you're talking about. But CNC is interesting

[@noddingat]

When you have me laughing while I'm learning about mesa -> linuxcnc linkage, yep that's a subscribe

[@rusticagenerica]

What the hell is that super powerful 3D printer ?? :)

[@aserta]

Once you scalpel about 47 processes, subroutines, hidden tasks, various pre programmed triggers and the such from W10, it becomes a very tame, modern W7. I will admit, it does take some time and Google Fu. BTW, a good way to get performance in a tight package (board) is to get a laptop board instead of a pc and use a PCIe expansion. I wish i had specifics, but a friend of mine is running a naked Asus ROG (i think it was a strix) as a CNC brain for an antique (formerly) tape numerical control lathe. He got that laptop for practically nothing because the gamer before him slammed the laptop cover over something, made the screen curved (features, amairaite) and punched through the "high" quality plastic destroying the keyboard as well. :)

OMG surprise reboot !! that was a good one bro

[@normannormiemates4844]

Finally Marco Reps shows his face!

[@electron-1979]

Not the first time! He doesn't deliberately hide his face

[@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.

[@-ahvilable-6654]

[@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]

[@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.

[@harviecz]

That Mesa FPGA card absolutely needs drivers for sigrok!

If you are running your servos in velocity mode and everything is in "correct" units, FF1 should be 1.

[@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

[@GlennHamblin]

Love your videos dude! Did you see that guy outside looking in through the glass blocks! Creepy! ... unless it was you being an Easter egg. 😎

[@bashaaksema94]

Maybe?

[@KrampWars]

From my experience of using a homemade cnc I would suggest you to pay a little bit more attention to the y z axes structur as you went over the top on x part but did not pay much attention on the support for the upper part. I have a cnc machine of simmilar size and power with the same axis configuration, but a lot beefier upper structure and i steel get a lot of vibrations on that part of the machine. Also i would recomend using aluminum and steel together as they help reduce vibrations due to difference in densities. Btw I enjoy the series as I do not have the funds to overcomplicate my machine to such extent.

[@raff96]

I hope you got those rittal enclosures used , they are pretty expensive ;) .
