I now have everything connected and working on the JL1 -except- the laser. 
Below I’ll quote the working config.yaml.
Maybe… but I didn’t really make progress until I grokked that the LowRider config has multiple Y motors each with their own driver, and the JL1 has a single driver and two steppers in parallel. I ripped out the extra config and things started making more sense when being reported with $limits. It has something to do with the LowRider config having endstops defined in the other motor driver.
What I had to do here was rip out the extra motor configs, then set the config as shown in the config.yaml below.
Earlier, when I was jogging the X and Y, the axis moved in the correct direction, so I knew the connector at the jumper didn’t need to be flipped.
Regarding the out of memory errors and reboots, I am able to reproduce that semi regularly.
Steps:
- Connect up a USB cable and have fluidterm running.
- use the file menu on the FluidNC web GUI and upload a config.yaml file.
- Close the file menu
- Restart FluidNC with the red power button icon on the UI.
- Usually, things restart fine. Once an a while, they do not. Both times it happened, I saw the out of memory errors as described further up in this post.
Below is the config.yaml as I have it, and everything I have tested is working fine. Now I will try to sort out the laser.
