Well, all the controllers on that list are based on the old 8-bit Arduino design and only support 3 Axes. Also, a lot of them don't have any isolation or noise control so EMI can cause problems like controller reset while running. In my design, I have tried to use best practices to minimize EMI problems. It supports up to 5 Axes so that meets your needs. My board is available on Tindie and you can learn more about it here.Hey buddy you are controller just looks amazing. i think you can help me as i am also looking for GRBL CNC Controllers and i don't know how to make them so looking to purchase. So according to you which controller will be good for me. My requirement are :-
Supports 4 axis
Supports integration with 3 stepper motors
and if its comes in good price range then it will be jerry on the cake. I also check one article on these GRBL CNC Controllers and got some good recommendation but want to know other options from community.
You controller is also just awesome.
Did you make customized cnc controllers ? If yes, then i think you can help me
Or if you know any best option then plz let me know
Either way have a good day
Hi all.
I have this board and this is best choise.
I overclock my teensy 4.1 to 1Ghz with extra cooling.
I have write my cnc controler with s-curve acceleration. My max speed is 80mm/s. Teensy calculate next motion below < 10 us. And this is my interpolation time. Pulse width is 2us.
Work perfect. I dont like any grbl. For me best way is write own software to this board. In c# I have software to comunicate with teensy. With grbl i have all time problem. So no tnx
Hi Phil,
I bought my Teensy4.1 NC board a few months ago and just getting back to it now.
I have a custom machine (not a chip cutter, laser cutter, or a 3D printer) that uses independent X, Y, Z, A and B axes. I needed 5 axis stepper control, so I got your card.
Theoretically it should be pretty straightforward to set up and control. Theoretically... famous last words...
I have ran an Arduino and a Raspberry Pi for 3 axes control in the past.
This is my first project with an NC board that interprets G-code.
Couple of Questions;
1) Is there a total noob's guide to how to get it working? Found this link on your github but looks like some of the folders referenced in this guide are outdated. https://github.com/phil-barrett/grblHAL-teensy-4.x/blob/master/grblHAL Build Guide.pdf
2) Must I solder the Teensy4.1 onto the board per the user manual? is there an IC socket I can solder to the board first? I am worried that if I toast the Teensy for some reason, I will not be able to replace it.
3) I realize that the kit requires quite a bit of soldering. Although I have a decent soldering iron and helping hands stand...etc... I have limited experience with soldering. What are the chances of damaging the board because I let the solder iron touch the terminals for too long?
See the attached photo of the correct orientation of the Trimmer Potentiometer. The footprint on the board accepts 2 different styles of trimpots. I moved to a higher quality multiturn trimpot. Ignore the 4th hole.
The document needs to be updated with the V2.09 board details. The serial interface has the 3.3V pin added so please solder in a 4 pin header for that.

Apparently this is a recurring theme with the Teensy boards where the PC does not recognize the device. I was advised to try a 4th USB cable.
Hi Phil,
My PC can not see the Teensy in the Arduino IDE. I have tried this on 2 different PCs with 3 different USB cables.
It looks like I possibly have a bad Teensy4.1 (yes, after having soldered the Teensy on to the CNC board).
It gets power. Stops blinking the light when I push the tiny button on it. But when it comes to communicating with the Arduino IDE - no dice.
For future newbies you might want to advise them to troubleshoot the Teensy by itself prior to soldering on to your board. I should have done this.
Is there a way to desolder(unsolder?) the bad Teensy and recover the CNC board? Do I start all over?
I am really bummed out about this outcome. Apparently this is a recurring theme with the Teensy boards where the PC does not recognize the device. I was advised to try a 4th USB cable.
What are my options going forward? I don't want to spend more money on another Teensy to have the exact same experience.
Do you sell finished boards with the Teensy already tested out?
So now I am trying to burn the config file onto my Teensy CNC Controller.Glad it worked out. So many times what looks like a dead board is because of crap cables or power supply or broken PC or ...
