The laser is getting a controller upgrade to prevent it crashing. This should help alot.
Thus far it has shown it self to be most capiable of doing high complexity tasks without crashing.
Please not that untill it is fully installed it should only be worked on by a "trained professional" (i.e. someone who vagely knows what they are doing)
The upgraded controller
The new and improved controller is a BigTreeTech SKR v1.1; a mostly open source smoothieboard derivative, running an LPC1768 at 100MHz.
The new and improved firmware is a version of Marlin 2.0; and is currently being pull requested in to the main Marlin branch here
It is recommended that the code be compiled in VSCode using PlatformIO. Please note that compilation takes time so Get your wooden swords ready
Connecting the controller
Controlling the controller
The control board runs a modified version of the Marlin, that supports many standard marlin commands
Pronterfaceis a good tool to connect to the board with, but lacks a lot of automation
Using the SD
Due to the bandwidth limitations, and lack of Real Time processing on most operating systems, the SD Card is the prefered way to run any non-trivial cut
The relevent commands are:
M22- Unmount the SD Card - This will make it show up as a USB flash device
M21- Mount the SD Card
M20- Enumerate SD files - Returns files in 8.3 file names
M23 <Filename>- Select a filename - Must be an 8.3 Filename
M24- Run file
M25- Stop file
