K40 laser controller board lightburn5/21/2023 ![]() ![]() Regarding the 32-bit stm32 and atmel chips, atmel is the original grbl dedicated chip. They acknowledge the speed advantages of the 32-bit platforms:Ībout STM32 and atmel chips? (2020.10.31) Take a look at this excerpt from the NEJE wiki. I’ve seen a number of discussions on speed considerations for this. But for things like engraving and traversal moves this could very much be a limiting factor. This probably won’t be a limiting factor for most diode cutting operations. This is especially true for more computationally intensive operations like arc moves. ![]() You may be speaking theoretically but the limits of the 8-bit arduino platform has run its course in the 3D printing world and in the laser world as well largely because of performance considerations.
