    Does anyone know of a GRBL Controller that is EstlCam ready and can handle nema 23s? I have an MPCNC with nema17s and a Arduino/Mega with Estlcam installed and I love the ease of using Estlcam to run it. But I'm starting a shopping list for a new Ox build and I would like to keep Estlcam as the GRBL controller software.

    I am also a MPCNC builder looking to build a new machine. Christian has on the estlcam website that it supports the CNC xPRO controller that openbuilds sells.

    Are you going to cut your plates on the MPCNC or buy them?

    I'm confused as to what you're looking for? Can't you just install GRBL (or Estlcam for that matter) onto an Arduino Uno?

    I sure as heck hope so, as I'm in the middle of a new build myself and all the electronics are almost done and that's what I'm planning to do. Five Nema23 motors.

    What are you using for the electronics? I am still looking for what to use for mine.

    I went with the Arduino Uno R3 for the controller and KL 5056 drivers for my NEMA23 motors. Motors will be powered by a Meanwell 48-volt 12.5A switching power supply. I purchased the Arduino on Amazon and the rest from Automation Technologies.

    The Arduino, fans and water pump will be powered by a Newstyle 12V 30A power supply also from Amazon. (I already had this on hand so I figured I'd use it.) Stepping the voltage to the Arduino down to 9V with a Supernight 12V 8A dimmer.

    I decided to make my control box self-contained (no hard wires to anything), so I'm putting sockets and connectors on it for everything. I'm using 5-pin aviation connectors for the motor wires. These are very cool, but piece of advice if you decide to use them: Get the bigger ones! Soldering to these tiny pins is a pain.

    Thanks for all the links. I am thinking I want to not have hard wired stuff but we will see how it really works out when I get going. I tend to just get it working and say I will make it better later but then just leave it :)

    Hey Retrosmith,

    Can you tell me how you are going to connect the drivers to the Arduino? Is there a shield you can use for this? I am mostly finding people using larger external drivers are using a break out board and mach3 but I am thinking I would like something with an Arduino running Estlcam.

    I'm using a proto-screw shield that mounts on top of the Arduino board to make connections easier (screw sockets instead of pins) but that's all. Estlcam has several different pin layouts, all shown in detail under the Setup/CNC Controller menu.

    No problem! Full disclosure: I have not finished this project so I can't confirm this setup works at all, much less works well. It *should* work perfectly, but I won't know until I'm able to hit the ON button. ;)

    Sounds like it should work to me but I don't know what I am doing. I already have a UNO and Estlcam and whatever drivers I get will work with something else so I wouldn't be out anything anyway. I am pretty far from needing this anyway the parts I ordered on the black friday sale just shipped.

    Hope I am not asking you too many questions but you seem to be doing what I am wanting to do controller wise.

    The Y axis is going to have 2 motors (on mine anyway) how do you connect the two motors? Do you using one driver for both and connect them in parallel? If you use two drivers you must connect them both to the same step and dir pins on the Arduino since there is only one for each axis?

    My Y and Z axes have each got two motors. Each motor has its own driver. Each wire that goes from the Arduino to the Y axis (step/dir) it split in two after it leaves the Arduino and one wire goes to each driver. That splits the control signal, but each driver has independent power.

    Here's a picture of the controller box:

    Here is how Kyo demonstrated it and it worked for me and my Arduino set-up with DQ542MA drivers and a screw shield (skip the Rasberry Pi part unless you are using that with the Arduino). C-Beam cnc Also, read this: Connecting Grbl · gnea/grbl Wiki · GitHub and this: Wiring Limit Switches · gnea/grbl Wiki · GitHub Personally, I would read the entire GRBL Wiki. I found it very informative.

    I didn't consider hooking the drivers directly to arduino. I thought it would need a grbl shield of some sort. Thanks for the info guys. Opens up more possibilities for me. I was looking at vpro but wasn't liking the price. If I blow it up, that's a lot of cash to swallow
