About to start building my first CNC (an MPCNC Primo) and am planning to use Bart Dring's 6-pack and run fluidnc. This walk through was very helpful for getting an overview of the firmware before I dive in.
Very insightful video! Thanks for this. I have managed to get everything running for a machine with one X and two Y motors with dual endstops. I have moved the Z motor over to be a second Y motor and everything moves as desired. But when I home the Y axis it doesn't bounce back, it just sits there and then fails. The X axis homes perfectly. Any idea why the Y axis is not homing right?
Bravo for your explanations I have the same card as you I would like to configure my laser which is CoreXY which yaml file should I take? Is the laser connected to TTL? Do you use limit with 3 wires?
How easy it would be to setup a CO2 Laser with this board? I've seen people selling shields with ESP32 and FluidNC for K-40 lasers to be able to use Lightburn directly but they asked arround 100-110€ shipped
Thanks for the video! All the config files I have found do not show the control: and macros: ... are there any sample config files showing these? - it's strange they have been left out
Thank you for posting this. I am gonna use fluidnc for the first time too. I am building impact etching machine, it will have a diamond engraving head instead of laser. I am little confused with double y axis though. Is the second y motor gonna use the motor driver of z axis ? Or one driver is enough for 2 y axes?
@@brakthehun I am gonna oscillate it. If I want to use 2 drivers for y axis then I have to add motor1 under y axis parameters, but I will have to copy all parameters from the motor0 of z axis in config file. In this case, second y axis motor is gonna use pins of z axis on the board. Am I right? Thank you in advance !
I have a mks dlc32 and I configured it following your instructions and it works fine but the G53 boot code part does nothing, could you please help me?
Nice job on the tutorial, I was able to get about 90% through it and got stuck on the dual Y motors part. I'm using a MKS DLC32 v1.1 board, I have my yaml setup just like you did in the video by copying the Z motor0 to the Y motor1. My problem is that now after reloading the yaml I get Y and Z moving together and z will not home anymore. Any ideas what I'm doing wrong? I commented out the extra motors so I could continue to work on it. But you can see below the Y and Z where I made the changes.

Hi, do you know why I can't upload any other config file with changes using fluidterm as you do here 27:55 ? I have to erase all flash memory and install everything once again even when I did some little mistake in .yaml. Im getting Return -2.
@@brakthehun yeah, I've selected the right COM port. I installed and uploaded older version of FluidNC (3.5.0), the same you have used and I got rid of this issue. However, I'll use an Arduino Uno to finish the project as I am using standard ESP32 DEVKIT V1 and do not have MKS DLC32. I've tried to use TXS0108E level shifters to send the signal to DM542 stepper driver, but my stepper motors are going crazy, they didn't want to move even when they were supposed to, I've erased everything from ESP32 once again and uploaded some simple code to control only one motor (X gantry), just to move and be still. And guess what happend :D All motors (other Y and Z gantry) which were not supposed to move had worked as I described in code along with the specific one I've programmed and wanted to move. The stepper motors operation is unstable, I don't know what it can be, maybe it's my skill issue in soldering as I'm doing the project on a prototype board, or some ESP32 soft problems, or just bad hardware connection.
