Eleks L6 Controller

Yeah, you can do a lot more with the micro when you have some memory and pins to spare

There are plenty of unused I/O pins. My grbl replacement code is currently:

   text      data       bss       dec       hex   filename
   9642       494       879     11015      2b07   build/gci.elf

So the micro's are pin compatible with the Nano?

I looked at the micro pin chart and still not sure what it would take to get it to run with say, grbl. But that controller would be a big step up. It will be limited by the board. A pretty good choice if you can get a firmware on it. And with your updated board it will be a strong combo.

The F303K8 is the better choice at 72MHz with 64KB flash and 16KB SRAM better SRAM than the Mega. The F031K6 is at 48MHz but only 32KB Flash, same as the Nano, but it does have 4KB SRAM so more SRAM than the Nano.

They have limited pin count just like the Nano but the F303K8 has the resources and speed for future work. And not a bad price either. Great find!

I have no expectations that they will work with the existing AVR based grbl code or with the existing Eleks power MOSFET circuit. My laser is working quite nicely right now and I want to finish up some of the existing tasks before getting lost again.

Some work already done on the STM32. But this might help you later on.

Thanks!!!!!

I ordered one of the neucleo boards from STM this morning and it is on its way.
