FluidNC // Beginner tutorial // ESP32 GRBL

[@wiremonkeyshop]

Two quick tips. I just got my ESP32 and was getting fatal errors when running the install-wifi.bat. Basically the board was not recognized by Windows 10 despite it beeping upon connection. I downloaded and installed windows drivers for my particular ESP32 which was manufactured by KeeYees. That didn't do the trick, but holding down the "boot" button on the ESP32 the entire time the FluidNC was installing, allowed the batch file to find the board and the upload was successful. Off to the races!

[@NEWTechCreative]

Great point 👍👍

[@slakjawnotsayin5451]

Wow, I just had a hell of a time putting this on my ESP32 I just got from amazon, but I managed to get it working finally, by doing the 10uf capacitor trick. That wasn't working for the last few hours, and I was trying other cables and anything I could think of, but it turns out, these ESP32 boards I got, are pinned different, so when I actually located and used the proper GND and EN pins, it worked perfect instantly!!! Just as a heads up to anyone struggling to get their ESP32 to connect and be able to write to, check to make sure your pins are correct, and don't just trust the pins on other peoples boards online in images and videos... Some of these things are different... I almost gave up and ordered a new one. LOL

[@NEWTechCreative]

Great job! Thanks for your feedback and sharing valuable information 👍

[@Chipageo]

This is the only video you can find on youtube about ESP32 with Fluidnc! great explanation. 👍

[@NEWTechCreative]

Cheers mate! 🤩

[@wiremonkeyshop]

The us a really great primer on FluidNC! I'm about to embark on an upgrade from grbl + Arduino to FluidNC + ESP32 and am very excited about it. grbl has served me well for years, but it's now time to join the revolution. Cheers! Important to note that multiple axis beyond 3 are not simultaneous. At least that is my understanding, for those of you wanting to build a 5 axis machine.

[@NEWTechCreative]

Thank for your comment! Wonderful to hear you are making the jump fro grbl. My workbee only made the jump from an arduino uno to esp32 last year and made a huge difference especially with the pulses. Due to the esp32 ability to process faster, I was able to achieve more then double speed output due to more processing power. No, fluidnc can independently move all 6axis simultaneously! Great for multi axis machines 🤩🤩

[@wiremonkeyshop]

Hey, is there a particular ESP32 board I should be purchasing, in terms of quality, features, etc. I bought the 6 pack board, but I'm unsure if which ESP32 to purchase. Any links or tips would be appreciated.@@NEWTechCreative

[@NEWTechCreative]

Thanks for your comment! I assume you are referring to Barts 6 pack board? wiki.fluidnc.com/en/hardware/official/6_Pack_External Checkout the esp32 Module section for more info. Note- This needs a 38pin esp32 wroom board!

[@j.hankinson7803]

Thanks for posting. I’ve followed a similar journey with an MPCNC and a variety of control boards. The original ESP32 Grbl Bart wrote was really good. I ended up modifying an Uno shield to run the motors and 4 axes. I’ve been waiting for FluidNC to mature and this video suggests that it has. I never had a problem with BT on my earlier build.

[@davidtaylor6870]

Thanks for your response. I will order the bundled screen option, and give it a shot.

[@adam.southside]

Thanks for the video .. at 7:36 you mention you built a CNC machine wiring directly to the ESP32 - can you please send a link or where to find the instructions for this - Many thanks!

[@NEWTechCreative]

Thanks for your comment! Yes here is my MPCNC video that I use an esp32… if I was to do it again- I would not use a stand alone esp32 and purchase a CNC/3d printer purpose ESP32 board to make process easier. kzbin.info/www/bejne/hqCpe6ilp7ekjdk

[@drakandres]

hello good evening Could you help me if I want to control two stepper motors with the esp32 and receive the g code which configuration should I use?

[@NEWTechCreative]

You can use any board that is compatible with the ESP32 and just use 2 axis only. The yaml configuration depends on what board you have. If you have just an esp32, you can use the 3axis_v4 setup and just select the z axis. Good luck 👍

I suspect its a clone of a "ESP32 I2S 6 Axis Driver Board", it has 3 74595s and an H-bridge. I looked around and couldn't find a match for existing board. It probably a clone of Dring's 6-Pack controller. I guess with these startup messages, its possible to setup fluidNC's config files.

[@NEWTechCreative]

This this the board you have purchased? wiki.fluidnc.com/en/hardware/3rd-party/ESP32_6_axis_breakout_board If so, I have mapped the board already (yes it was painful). Upload fluidnc and use the yaml file from wiki link I have above. The spindle and mist out are 24v. I think this is intended to use the variable amp setting in vfd, however untested. You will need to supply 24v to board to upload firmware.

[@CraigHollabaugh]

@@NEWTechCreative Ha! Yes, that's the board! I spent 4 hours this afternoon doing the same thing. Used the machine.h (from their github repo) to config.yaml converter. Then flashed FluidNC from the latest release without any problems. I learned a lot about FluidNC during this process. Its so simple now to get a board running. Verified 6 axis, limits, spindle and mist. I looked over your file and there are a few things that should be changed (for example, motor stepstick should be standard_stepper, also ms3 doesn't exist.) I'll finalize and confirm mine then get it to you.

[@MeanderLife]

Fantastic Overview! Thank you for creating it. Big question... for "non-standard" mechanisms and machines (I.E. SCARA, or cable-style like Maslow) where motor steps / mm are not consistent through the movement, and need to be calculated based on position with an equation. Is there a method or place in the settings to accomplish this? I could see this as a platform to accomplish all types of automation control on so many machines I have in my head... but so many are not a straight 1:1 step per mm mechanical set-up...

[@NEWTechCreative]

Thanks for your comment! Great question. I agree with you! Yes there is a range of kinematics available on fluidnc and yes I have seen a basic wall plotter style project using fluidnc. The Maslow style already has its own fork of the fluidnc project and looks great (google fluidnc Maslow). You can also create your own kinematics if you are savvy in the coding space and compile your own version. You can find some of the kinematics available here: github.com/bdring/FluidNC/tree/main/FluidNC/src/Kinematics

Fantastic! Thank you for the reply. Now hopefully I can dust off the brain cells and revive the ideas...@@NEWTechCreative

[@f1hotrod527]

I want to switch away from Mach4 for my CNC router. I want the new style wifi type firmware like 3D printers use. I think I have narrowed down between FluidNC and buying a board from Bart, or Buying a Duet3 board and using Reprap. I wonder which one is more finished and will be easiest to implement on my CNC router? The good thing about Duet is I want to switch a couple 3D printers I have from Marlin to Duet / Reprap as well. So I could have a common hardware / firmware between my CNC machines and 3D printers.

[@NEWTechCreative]

Great question. Personally I would stay with mach4 due to the dedicated CNC platform and flexibility in software, however if your intending to change, I would get frustrated using Reprap platform for CNC purposes. Reprap will have a reduced functionality for CNC use where as fluidnc is a CNC platform at heart. At the end of the day go with what you are most comfortable with and make it a learning journey 🤩🤩

[@flyingmonkey3822]

I’m using protoneer CNC shield and wemos esp32 breakout board, hoping this is similar! Thanks for the video tutorial, that Bart sure is amazing

Yes this looks promising… I can see the pins used on this website that you can easily duplicate across to fluidnc.. deeemm.com/cnc/2021/07/15/ESPduino-protoneer-CNC-Shield.html Let me know how it goes?

[@berinslaptop]

If the usb cord works for DATA on other stuff but not your ESP32. your missing "windows" com port drivers. install Windows CH340 Driver or CP210x Universal Windows Driver and you will likely have joy. For example, if you have a wemos d1 and the blue LED does not light up when you plug the usb port into a PC. Its because there is no com port. It needs a virtual comport driver. As well you will also need the correct .jason file and the correct board file/library loaded in arduino IDE.

[@NEWTechCreative]

Thank you for this Berin! Yes you are correct - since posting the video, the ESP32 can now communicate with windows 11 using the correct drivers! Great advice 🤩🤩

[@huseyinurigulmez]

Thanks for your explanations. I am building a lowrider v3 and mechanical work is done. I am supposed to build minimal control electronics (an esp32 dev kit and many breadboad rats nest) for XXYYZ configuration. I would be curious to see if it has enough IO for 3xEndstops, 4xTMC2209, 1xProbe, 1xE-stop and 1xRelay ? I don't really need dual endstop and fancy laser stuff.

[@NEWTechCreative]

Yes this is possible if you set up with XYZ and just split the direction and step pins out to two XX and YY drivers. Or just use one motor driver with two steppers as long it can supply enough power for both motors. This is how I setup up my MPCNC and just swapped the stepper motor wires to mirror the motor directions. I hope this makes sense?

[@whitneydesignlabs8738]

What "off the shelf" CNC boards are y'all running? I looked at Bart's new universal 6 axis. Looks great. Clearly a ton of R&D in that board. But a bit over my current budget, especially with all the modules adding up. My whole project is based on scrap/repurposed parts etc., with the exception of electronics. The MKS TinyBee hits my price point, but Amazon is out of stock (I am in USA), and Aliexpress would be a delivery end of Feb. '23. Many of the other options on the FluidNC wiki are no longer available. I'll refrain from listing my criteria, as it is quite low. Just want to do some testing and learning on a minimal budget.

[@NEWTechCreative]

Unfortunately it’s one of those decisions you will have to weigh up… spend more to receive faster or spend less and wait longer!! Due to the Chinese new year, most Chinese suppliers are on holiday until end of January and longer wait times. I would head over to the Discord server and ask around as well! I’ve also purchased the tinybee a few weeks ago and should arrive soon… it seems to have most bells and whistles.

I just bought the V1Engineering Jackpot CNC Controller, I want to go with Nema23's for my CNC it has onboard TMC2209 Drivers... is there a way to bypass those and use external drivers for the bigger steppers ?

[@NEWTechCreative]

Great choice 👍 yes absolutely you can bypass having to use plug-in drivers only. If you flip the board over, it will tell you the step, direction and enable pins for each driver output. If you deliver those drivers, you can use jumper wires to hijack the signals to your external motor drivers. Just remember that this is only possible with drivers that have a 0v or GND input next to the drv,stp,ena and GND … not 5v. I have explained how to swap to a 5v version on my wiring video. Let me know if you need further clarification?

[@AlexIstEinGott]

I ve made a config.yaml to test on an esp32. Fluidnc setup went good, config upload works but it gives me an error that says the stepper motors step_pin has to be a gpio pin. It is currently configured as an I2SO pin because I'm planning on getting the 6 pack external driver controller and the wiki says the 6 motor outputs use I2SO pins.

[@NEWTechCreative]

Great idea to test on an ESP32! For the i2S to work you will also need to include the setup for the i2S as follows: i2so: bck_pin: gpio.25 data_pin: gpio.27 ws_pin: gpio.26 Drop this above your stepping setup on your yaml file and should work fine. Let me know how you go?

Hi How control the dc spindle motor with software

[@NEWTechCreative]

Thanks for your question! Here is the main information regarding spindles: wiki.fluidnc.com/en/config/config_spindles If it is a basic on or off function you require, you can just setup a relay to turn on/off dc spindle. Most spindles have a speed control function that you can control through fluidnc and worth while reading up using the link provided. 🤩🤩

Great howto, but it is possible to add a macro on FluidNC to run the frame area before the real gcode ?

Great question! Unfortunately I’m not aware of such macro, however I often use universal gcode sender with fluidnc and has that option. There are a few more gcode programs that are popping up that play nicely with fluidnc and allow extended features like this. This might be a good video in the future 👍

Does anyone know how to calibrate the steps per millimeter for the XYZ axis. I’ve been looking all over and I can’t find any information. Thanks.

Why is this so hard? I’m not a programmer, shouldn’t have to be, I know how to set up my DIY CNC table just fine in an Arduino.

Make sure that the 10k resistor goes from 3v3 pin on board to pin34 then connect the button from pin 34 and GND. Ensure that the yaml file is setup correctly with gpio.43 . I would double check the following: - check pins with a multimeter to ensure pull-up voltage - check that button is pressing and making a connection with a multimeter - when pressing button, fluidnc is unlocked and running - check that there are no errors on startup with the fluidterm usb connection. - check that there are no spelling or grammar errors in yaml code - check that you are using the correct yaml file setup on your fluidnc

[@NEWTechCreative]

Thanks for your comment! You can upload the .nc file over Wi-Fi to the Sd card (if you have on attached to your esp32) and run directly from the esp32. The esp32 doesn’t really like Sd cards any larger than 8Gb, but as long as it’s fat32 formatted and under 8Gb, you can plug in and read from file system via esp32. Alternatively you can also connect via usb and control using a g code send such as UGS, CNCjs or focus and not use the Sd card at all 👍👍

[@hudsongaspar]

Thanks for the video. I need to change the standard engine ports for board development reasons. In this case, do I use the recording medium via the Arduino IDE?

[@NEWTechCreative]

No need to use Arduino IDE. To change pins, just change the yaml file for fluidnc and upload either by fluidnc term or the web ui 👍

[@alhaddar14]

I had a problem when I modified the 3axis_v4.yaml file with Notepad++, and when I uploaded the file and opened it with the command $cd, it appears like this. steps: engine:RMT idle_ms: 255 pulse_us: 4 dir_delay_us: 0 disable_delay_us: 0 segments: 12 spi: miso_pin: NO_PIN mosi_pin: NO_PIN sck_pin: NO_PIN sdcard: cs_pin: NO_PIN card_detect_pin: NO_PIN frequency_hz: 8000000 kinematics: Cartesian: axes: I have to edit my pins like this spi: miso_pin: gpio.19 mosi_pin: gpio.23 sck_pin: gpio.18 sdcard: cs_pin: gpio.5 card_detect_pin: NO_PIN The pin numbers do not appear when the file is modified So what is the solution? Please Help

[@NEWTechCreative]

Great question! You might need to update what yaml file name your are using in the ui. Try changing the yaml file name to config.yaml and re-upload. This should fix your issue

[@alhaddar14]

Thank you for your help.

[@rusticagenerica]

May I ask you what would be the very best ESP 32 board money could buy?

[@NEWTechCreative]

Great question!! This might be a great episode down the track reviewing multiple boards. If your intending for use with fluidnc, unfortunately the newer s3 boards aren’t compatible as yet, however for CNC purposes I would definitely look into the root controller rev3!! There are a decent range of boards already available varying in quality and functionality!!

[@steveu235]

Don't know much about this stuff so please forgive me if this is a stupid question. Can Fluid NC be used for a CNC plasma table

[@NEWTechCreative]

I’m not an expert regards to plasma tables, however there are other users who are using fluidnc for plasma cutters. There is a whole discord channel on the fluidic discord dedicated for plasma cutters and should definitely check out!!

[@kayakMike1000]

Is this tensillica or risc-v. GRBL was originally developed for crummy slow atmel bullshit microcontroller. The way GRBL is designed seems to get the job done, but ... is there a better way GRBL? I suspicious you could make multi axis coordinated indexer program that is much better than GRBL....

[@NEWTechCreative]

I’m using a 240 MHz dual core Tensilica LX6 ESP32. I do like the simplicity of grbl and even after using mach3 I would rather use grbl. It’s more then enough to do what I need!! I’m still using an atmel uno on one machine and still kicking strong!! (However I can’t wait to upgrade)

[@roccovicedomini8535]

I would like to test FluidNC on my ESP32 dev board but, in case I need to bring it back to my usual Arduino IDE environment for simple automation circuits, is it possible/easy afterwards to reset the board to the initial state ?

[@NEWTechCreative]

Absolutely! Fluidnc comes with an erase tool to wipe the ESP32.

[@rusticagenerica]

Would this also work on Linux?

[@NEWTechCreative]

I believe this is possible! However I am not familiar with Linux.

[@rusticagenerica]

@@NEWTechCreative thank you :)

[@kript24]

is it possible to run gcode from internal storage?

[@NEWTechCreative]

Absolutely

[@kript24]

without sd card???

[@NEWTechCreative]

Correct! To access local storage system in the fluidnc tab - send command $LocalFS/Run=insertfilename.nc Keep in mind that you very little memory to work with. On my wroom32 I only have 50kb of free memory after installing necessary files. After adding any Marcos, you might not have much to play with.

[@Z-add]

Is this just as capable as uccnc?

[@NEWTechCreative]

Absolutely… uccnc comes with a really great UI with plenty of buttons and visualization that fluidnc does not provide on the webUI, however if you use cncjs, UGS or focus by sourcerabbit, you can take advantage of these additional features with fluidnc 👍👍

[@coopshopdesigns4890]

Does it support torch height control

[@NEWTechCreative]

Great question. I haven’t ventured into plasma cutters, however there is plenty of discussion on this topic on the discord. Feel free to head over and check it out 👍👍

[@Zeix02]

This only work with wifi?

[@NEWTechCreative]

Also works via Bluetooth or tethered via usb 👍

[@lloydrmc]

So what this is, is Smoothie Board software ported to whichever random ESP32 board you want to use. Brilliant. Another way to look at "shift registers" is converting SPI serial to parallel, to break out individual bits. There SHOULD be a way to make this bidirectional. Hmmm... That gives me an idea!

[@NEWTechCreative]

Haha! Maybe a future project for you??

[@rodwheels]

This is just amazing, congratulations!!!

[@platin2148]

Can it Drive Industrial Ethernet Servos?

[@NEWTechCreative]

I know that fluidnc supports many types of motors. Head over to the discord server to find out more details! 👍

[@rickharms1]

I missed something. How can you upload, or find a new ESP32 if the WiFi on it is not set up?

[@NEWTechCreative]

Two ways for this: 1. Over USB port and using the fluidterm to setup - fluidterm is in the setup files. Use the $ commands to setup. More info here: wiki.fluidnc.com/en/features/wifi_bt 2. You can connect directly to the esp32 over its own access point. Once fluidnc is uploaded to the esp32, it will create its own wifi to connect to called ‘fluidnc’ password 12345678

[@mak8221]

8:10 this board has major pcb design issues! just look at the placement of the esp32! with copper plane under it!

[@NEWTechCreative]

I agree that this board has some design issues. However, I’m not entirely clear on your point about the copper plane. Most boards will have a copper plane or ground plane, which also assists with heat dissipation. If you are referring to the black section under the ESP module on this board, this is an antenna area.

[@denniskramer9788]

Can it drive a 4 axis plasma table and manage THC, torch height control?

[@NEWTechCreative]

Great question! I’m not sure exactly on this. If you can usually setup with a grbl controller, it could be possible. You might have to head over to the discord and ask the community. Thanks Dennis 👍

[@macmaniacal]

Is there gcode visualization? And live toolhead view?

[@NEWTechCreative]

Great question!! Unfortunately not on the webUI (at this stage) however if you use a 3rd party software with Universal gcode sender, this is possible. There are a few folk currently dabbling in these functions!

[@stefandebruijn3167]

Yes; Candle, CNCjs, and a ton of other senders all support that.

Fantastic video and overview of FluidNC. Do you have any recommendations for an MPCNC user that wants to maybe give this a try? I looked at the 6 pack boards but by the time I get it in Canada it’s over $300 for the options I want.

[@NEWTechCreative]

Thanks for your comment! I hope it assisted with some of your questions. If you are after dual axis control… so 5 independent motor control XXYYZ you should purchase a board with 5 motor driver capability such as the MKS tinybee board as you can use with internal or external motor drivers. The 6axis control board that you can see in my video can also do the same with external motors and you can just switch the motor outputs to XXYYZ instead of XYZABC. I’m not sure what you are able to get in Canada but you might have to do some research. Feel free to send me a link to see if you need a hand on what you decide to purchase.

[@sparks-tech]

@@NEWTechCreative thank you that is great. I think the TinyBee board looks good and is a pretty cost effective way to try out FluidNC as I can get it in Canada with drivers for about $75.00 As for the inputs and outputs is there a way to expand that at all, looking at doing dual endstops, spindle on and off and laser it looks like I will run out if I/O pretty quickly.

[@johnlocke9609]

@@sparks-tech the end stops are daisy chain, you don't need more inputs you just need them to be triggered once each axis is touched. In the other hand, if you need many inputs for other stuff, esp32 is not for you, because esp32 has limited inputs, it can and has many outputs as he shown with shift registers.

[@AS-ug2vq]

@@johnlocke9609 I want to control 3 motors max. 1 for x, y and z each respectively. No endstops, no limit switches. Just one relay for the plasma torch. Is it possible to use just esp for this?

[@whitneydesignlabs8738]

I am running a simple ESP dev board like you, nothing fancy, for my testing/learning rig. Connected to 3x TB6600 stepper drivers. Did you have to use a level shifter or are your drivers 3.3v tolerant? I am getting intermittent results with basic jogs.

[@NEWTechCreative]

Thank for your comment! I’m running the drivers directly from the esp32… no shift registers. Just check you have the direction pins and stepping pins in the correct pin… try swapping to test. Feel free to send me an email at [e-mail] with video if that doesn’t work!

[@NEWTechCreative]

I had one other thought… you might need to change your ‘shared_stepper_disabled_pin: gpio.13:low’ change low to high 👌

[@whitneydesignlabs8738]

@@NEWTechCreative Thanks. Tried that setting both ways, low and high. Strange I was getting action on the Y originally. Now no motion on any axis. I will double check everything. I must be overlooking something. Thanks again for the help!

I’m not sure if you are using the screw terminal breakout board, although I have had some issues with the terminal boards I’m using and not making good connections… I went back to using my diy terminal board and everything works perfectly. I hope your able to fix the issue soon. 👍

[@whitneydesignlabs8738]

@@NEWTechCreative For the moment I am using a solderless breadboard and Dupont connectors for testing. The issue seems to follow the wires coming from the ESP32. In other words, I have swapped motors, and swapped driver boards and the behavior stays with the associated axis from the ESP32. (eliminating driver configuration issues, bad motors etc). Currently my Y is working fine. My X just makes a tiny little movement, like a jitter. And my Z stutters back and forth for as long as it is getting step pulses. My .yaml file contains this: axes: shared_stepper_disable_pin: gpio.13:high I will definitely go back and seat and re-seat all the Dupont wires in the breadboard, to eliminate dodgy connections as the problem. I've double checked and don't have any control wires mixed up. Pretty sure I am wired correctly. Thanks again for taking an interest in this troubleshooting. Cheers.

I wonder if ESTLCAM will get an update for it. The writer of the program has left it sitting at 11.244 for some months now, so I'm hoping he's healthy and only busy, maybe working on a on aversion 12. It actually burns it's own custom GRBL equivalent for setup, I don't imagine it would be too hard for him to reassemble on the ESP32 platform.

I hope so! I’m sure they are catching up soon after the new year start.

Actually there's an incorrect bit, you can use input shift registers too. or you can use a cheat like I did years ago for digital inputs which is to multiplex the inputs by using some outputs to drive one side of your inputs in a group for each multiplex pin.

Thanks for your comment! Yes you are correct that you could use shift registers as inputs on microcontrollers, unfortunately I haven’t seen any boards available with this setup or using fluidnc. I think this would be a great addition in the future!
