Although the one I bought is an odd size. ( 14.2 mm ) I ended up grinding it down to 14. If I would have known how simple they are I would have just made one. All you need is an alligator clip to ground out on a slightly spring loaded piece of metal with wires connecting the two. **Q: Is this board compatible with Lightburn software?** A: Yes, the LightBurn version for GCode controllers will run on this board. I got the WOODPECKER CNC CAMXTOOL V3.4 and I’m running the current trial version (LightBurn V0.9.16) now and have found no problems. Note: the trial contains both g-code and DSP versions. **Q: How are the limit pins configured? Will the board recognize the pins or will the board just notify the software and its up to the software to stop?** A: The function of the limit pins is to notify the kernel on the board that they have been activated or deactivated depending on the type of limit switch you are using. IE a Normally Opened or Normally Closed switch. I do know the GRBL 1.1f kernel that comes with the board detects the change on the pins. However, you still need to set the software to do what you want it to do when detecting the change. IE like having the homing setting set in the GRBL settings $24 - $27 are the settings you want to set for homing. **Q: do you need other board like arduino to make this work? Does it comes with software?** A: Yes it comes with software and you don’t need anything else ## Customer Reviews ### ⭐ Had to return it as it would not work *by G***I on 4 March 2020* Would have been good if it had worked. ### ⭐⭐⭐⭐⭐ worked for me *by B***N on 30 August 2026* worked for me ### ⭐⭐⭐ El producto llego en el tiempo establecido. *by J***Z on 10 February 2022* Lo instale en mi CNC 3018Pro y el eje X se mueve en dirección opuesta. Espero el vendedor me pueda compartir un instructivo de configuración. Aparte el Software GRBL Controller lo marca como Estado: Desconocido, aun así se puede mover los ejes de manera manual pero no es ideal para usarlo directamente (plug and play). ## Frequently Bought Together - CNCTOPBAOS 3 Axis GRBL 1.1f USB Port CNC Engraving Machine Controller Board for CNC Router Engraver Milling Machine 3018-PRO 1610-PRO 3018-PRO-MAX Control Card - Genmitsu 6PCS Micro Limit Switches with 1M 3 Pin Cable for 3018-PROVer/3018-MX3/3018-PROVer Mach3 - SainSmart CNC Router Z-Axis Tool Setting Touch Probe, Compatible with Grbl/Mach 3 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/256469765-3-axis-grbl-1-1f-usb-port-cnc-engraving-machine](https://www.desertcart.in/products/256469765-3-axis-grbl-1-1f-usb-port-cnc-engraving-machine) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-09-12*
