Hello, I would like to thank you for generously sharing your knowledge and information with everyone. This demonstrates that you have a noble spirit. I am truly grateful.

Linux CNC with the Mesa is a great solution. For a lower cost and perhaps simpler solution, first-time CNC enthusiasts might do well to investigate GRBL on Arduino, along with Protoneer or ArduinoGRBL motor drivers. Just don't underestimate the huge and wide area of knowledge you will need to accumulate to make a success of such a project. Good luck to all that enter this arena!

@royk1374 Год назад

It depends on your needs, for a beginner who doesn't have experience with computers or someone that doesn't have a lot of patience I wouldn't recommend LinuxCNC either. But if you do have some patience and like to have as much as flexibility you want, this relatively low cost controller and free software is a great solution. As someone new to CNC I did however began with LinuxCNC 8 months ago and it was a pain in the ass at the beginning but I'm glad I did after all. With this software and hardware I'm pretty sure it will fulfill all my needs with al my future upgrades.

GRBL and arduino have worst if build cnc, only toy cnc but real work cnc need lot better than arduino and old cavemen shit GRBL.

@AlexMoonXXI 7 месяцев назад

@@mattivirta Actually, Grbl was created by a talented programmer from Norway. What are your complaints about him? Did you know that all modern 3D printers use Grbl algorithms?

Great video! Keep them coming 😁

@royk1374 Год назад

For easy connecting you could buy one of the cheap Chinese BOB with an idc26 female to db25 female cable, that's the 5abob configuration

Thanks for the advice.

I am interested in trying youbadvice can you link me with a link to the products you talking about or a video on youtube on how to go about this. Thanks

Hi in linuxcnc configuration wizard there is 4axis choice, how you install 5axis?

@a-cnc-f 3 месяца назад

It is not possible to configure 5 axes using the configuration wizard. If you start up Linuxcnc, you will find a sample of 5 axes, so use it and modify it.

hey you are back cool!

@a-cnc-f Год назад

Thank you. Even a simple setup can be difficult for those who are not familiar with it. I had a hard time too.

@cda4662 Год назад

you simplify things to make it easier to understand it

@mattivirta 11 месяцев назад

maybe perfect new cnc machine beginner have raspberry pi 5, lot fasten and future can add PCI card too if need, dual display etc.

@a-cnc-f 11 месяцев назад

I see that raspberry pi5 is now available. Thanks for telling me.

@mattivirta 11 месяцев назад

@@a-cnc-f interesting lot how this working whit mesa card and how lot have fasten etc, i just looking some yotube test video and normal softwares have 2-3x fasten, i hope handle jitter etc, lot better, interesting see how working whit linuxcnc. can you buy and test. pi hut has less than 80$ lot better than many old pc or other board.

@AlexMoonXXI 7 месяцев назад

Hi! I'm not familiar with the exchange protocol for the Raspberry PI. But why is MESA needed for this solution? For optical isolation and control of strong currents, a simple LPT-Mach3 board can be used.

@a-cnc-f 7 месяцев назад

Generally, LPT-Mach3 boards are designed for use with Mach3 software on Windows and may not be directly compatible with LinuxCNC.

@AlexMoonXXI 7 месяцев назад

@@a-cnc-f This is not true :) LPT-Mach3 boards are designed for use with parallel port any PC. They are widely used in combination with PC + LinuxCNC. They are simply a set of optical switches and relays that provide galvanic isolation between the PC and the controller.

I am kinda up in the air with this, I own a ras pi 4 with 4gbs of ram, pi3b+, a few other boards but my CNC uses a Zynq Xilinx SBC it's setup to be used for plasma cutting it uses windows 10 pro and they masked the remote software that connects to my CNC with their software name, etc , what I am trying to accomplish is using the existing setup for plasma and also use it for my Router and attachment but the problem I am having is I don't know anything about remoting into that sbc I have all the passwords they used and it's this version of Debian Linux for the Ras pi, I just want to be able to do both plasma cutting and wood & metal routing as they already offer all of this just our work schedules do not match up and I am used to trying to figure it out on my own without screwing it up. lol

@dogcreek-customs5168 Год назад

The Original SBC inside the machine is not a ras pi but it's running the software & machinekit so I am trying to take my rasp pi with linuxCNC to connect & control it as I hook up the ethernet wire to the pi the incoming and outgoing data arrows go crazy but I just to linux dumb and dumb to all these new sub layers for windows that they're using like their own linux kernel, etc

@dogcreek-customs5168 Год назад

So in ending I wanted to thank you for this video as a few things in my head clicked and I seen during the 1 year struggle I've been in but I will figure it out once I get a few more videos in me. Thanks a million!!!!

@bryomuch Год назад

i dont have enough time left ,i just want to see the lathe cutting,can you upload some shorts

@a-cnc-f Год назад

That lathe is now being wired. Not sure yet how far along the next video will be.

@SuperNovaTechnology Год назад

Which RAM size RPi4 do you use ?

@a-cnc-f Год назад

4GB

@keronGR 11 месяцев назад

So, to understand this, in order to switch to linux CNC for a 3-4Axis machine, endstop wiring and spindle PWM control, it is needed: 1) Raspberry Pi4 2) 7c81 mesa card 3) A flex cable 4) Cheap db25 cnc board 5) IDC26 to DB25 cable??? Please like my comment and correct my mistakes, I am trying to switch to LinuxCNC with a raspberry, because I have taken the shit with Mach3

@a-cnc-f 11 месяцев назад

You also need to make a cable to connect the raspberry pi to the mesa. You can download the manual for the 7c81 mesa card.

thanks a lot@@a-cnc-f
