This looks awesome! I'm currently picking out a CNC frame (leaning toward the Workbee / Queen bee currently, but not sure). If I can get it working with the basic 8 bit GRBL controller I'll look to upgrade to this one down the road.
Currently on Tindie there is only one left. Are you planning on re-stocking? (No rush of course... this is likely months out for me).
I ended up jumping on this after all, and got the last board. Now I just need my CNC components to arrive...
Finally got the CNC up and running, and carved a test piece, using this controller. It works very well, and I love some of the advanced features of GRBL Hal (such as auto squaring the Y axis, etc). Still have a long way to go (i.e. install a wasteboard, put the electronics in an enclosure, etc), but it is looking great.
Thanks Phil!
I looked at the grbl-HAL code on GitHub and looks like it supports G5 (cubic bezier splines) in 2 axes. Do you know whether there is a plan to expand this to all 5 axes?
Sorry for responding so late. I don't know the answer. You could ask Terje (the grblHAL developer) on the grblHAL github repository in the issues section - https://github.com/terjeio/grblHAL
Drew, those are real TB6600 drivers. I bought them a few years ago before the plague of fake TB6600s arose like Covid. I did a tear down on one of the current "TB6600" drivers - not a real TB6600 chip in it. https://www.grbl.org/single-post/tb6600-fake-or-not-but-who-cares I am hard pressed to find a driver built around a real Toshiba TB6600.
Just wondering what driver boards you're using in the above system.
I am currently sold out of boards but I have a new shipment waiting for carrier pickup in Shenzhen. Should be here by the end of the week.
Well, FedEx is a bit slower than I thought. They are now saying Tuesday11/24 though they some times under promise/over deliver. So, you might want to check the Tindie store on Monday.
Hello, a quick update. I am putting the finishing touches on a "Pro" version of the board. It includes FRAM for logging machine time, Pluggable Screw Terminals, USB Host support, high speed quad encoder support, spindle sync input and daughter card mounts for I2C and Serial IO. Updates as I start testing the first boards.
Thanks. It's based on a CBeam router from open builds. Here are some detail https://www.grbl.org/cbeam-machine
To be honest, wouldn't recommend the mechanicals. It's OK but I don't like the moving bed on a single CBeam rail. Better to get a small WorkBee. Happy to answer any other questions.
i know the project is about the controller, but i love the look of your cnc router.. any details?

I just wanted to send a note to thank you for this work and especially for the easy to understand blog post you made explaining how to find the pre built binaries and for the pin outs diagram on the teensy. I had struggled to understand how to build and use grbl from the main website, but your work helped me get grbl up and running, along with the gcode sender. And thanks for the tips about reconfiguring the settings for the safer connections being normally open or normally closed. Just wanted to send a note of appreciation that your work helped another fellow traveler find their way into making a basic CNC type machine. Many thanks!
