That your USB cable is a data cable and not only and charging cable and that its length is below 80cm.That the DTR control is activated (Edit/Device Settings).That the USB connection speed is correct (Edit/Device Settings): it should be on 115200 bauds.If so, your computer and laser cutter connected as intended. You should see indications similar to the one below on the console: This will restart the USB/Serial connection between Lightburn and the ESP32. Now right click on the “Devices” button in the right column. Then, under Lightburn, click on the “Console” tab in the right column. We will start by testing the connection of the ESP32 to your PC without installing the shield in the K40.Ĭonnect the USB cable from your PC to your ESP32 Please start by installing Lightburn following my instructionsĬonnecting the K40 FluidNC Shield to your computer
The use and implementation are very similar to the previous version Full control of the laser via Lightburn or other software using the GCODE.Control of your machine through Wifi including Lightburn direct control over Wifi.Only 1 dry contact relay instead of 2 before (the 2nd one was not used by my customers).Possibility to have an external driver fro one motor (if you need to use a NEMA23 for the Z axis for example).4 axes (to be able to manage a machine with two motors on one axis like XYYZ machines for example – 1 motor for X axis, 2 motors for Y axis and 1 motor for Z axis).
Seems like it would be fun.I have decided to move to FluidNC which is the successor of ESP32 GRBL which is not maintained anymore.įor this occasion, I have designed a brand new K40 FluidNC Shield which is offering much more features This post is only applicable for Shield version v7.xx Brand new K40 FluidNC shield – Compatible with Lightburn I was toying with the idea of getting a cheapo TL-A1/WT-A1/A20 for a while and I think I'll just order one. And for a bit more money you can get a Ruida RDC6432 from Cloudray.
You need some stepper drivers and, if your K40 uses that ribbon cable, you either need to redo the wiring or you need some kind of wiring loom or breakout board.Ī slightly more expensive option is a Ryxon KT332N. The panel is fairly narrow which means it also works with 70 cm wide compact/mini K40s or "4040" machines with a narrow electronics compartment.īut there are some caveats. Engraving performance should be quite a bit better than what you can get with any of the g-code options. There are of course also buttons of jogging, framing, and whatever. It got a color screen, supports 3 axes, got Wifi, and a socket for a USB stick. The TopWisdom TL-A1 aka WaveTopSign WT-A1 aka LightObject A20 DSP controller + LightBurn DSP license is roughly in the same price region as a LaserBoard + LightBurn g-code license.
