00:00If you're building or upgrading a CNC machine, the controller board is basically the brain of
00:04the whole operation, and picking the wrong one can cost you hours of headaches. So I went down
00:10the rabbit hole and found the best deals out there for the top 5 GRBL controller boards for CNC,
00:15and trust me, there are some serious bargains on this list.
00:19First up is the PyBot Fluid NC ESP32 GRBL CNC version 4.96 Pro Kit, and this thing is a
00:25favorite for good reason. It runs Fluid NC on an ESP32, which means you get Wi-Fi, tons of I
00:32.O.,
00:32and support for just about any stepper setup you can throw at it. It's priced at $59.44,
00:39and with almost 5,000 units sold at a 4.3 rating, it's clearly a proven workhorse.
00:45If you want a premium, future-proof board that can handle serious builds, this one's worth every
00:50penny. Next, the GRBL 1.1 USB Port CNC Engraving Machine Laser Control Board, a 3-axis board built
00:58specifically for the 3018 Pro with integrated drivers, and you can even add offline control.
01:03At just $19.26, it's an absolute steal, and the fact that it's sold over 4,800 times with a
01:10perfect
01:105-star rating tells you everything. If you've got a 3018 or similar small machine and want a cheap,
01:17reliable drop-in replacement, this is the one. Then there's the MakerBase MKS DLC32,
01:23an ESP32-based GRBL controller that works with both lasers and CNC, and it supports Wi-Fi plus
01:29the TS35 and TS24 touchscreens for a really clean interface. Here's the wild part, it's listed at just
01:36$2.70, which is almost unbelievable, and with over 4,600 sold at a 5-star rating, people are clearly
01:43loving it. If you want modern features like Wi-Fi and a touchscreen without spending much, grab this
01:49before the price changes. Coming in fourth is the upgraded 3-axis controller board, which ships with a
01:551, 1.8, or 3.5-inch offline display so you can run jobs without a computer hooked up. It's
02:02$23.22
02:03and has moved over 4,500 units with a solid 4.5 rating. The offline capability alone makes it worth
02:11it if you're tired of tethering your laptop to the machine every single time you cut something.
02:16And rounding out the list is the USB GRBL 1.1 FCNC controller card, a 3-axis board that supports
02:22lasers, limit switches, and an e-stop, all for $22.10. With more than 4,400 sold and a perfect
02:305-star rating, it's a dependable pick for popular machines like the 1610 and 3018.
02:36If safety and flexibility matter to you, the limit switch and e-stop support make this a really smart
02:41buy. So there you have it, 5 GRBL controller boards that cover everything from budget builds to full-on
