Beware Luban 4.9.0 + Stock 2.0 Firmware

@VaporPhoxxe Brought it to my attention that the inline bug of not turning the laser off when S0 is requested from firmware 1.14 is still not fixed in the latest 1.17.17. It was brought to light as the new 4.9.0 version of Luban finally begins to introduce inline code (the same Lightburn users have been enjoying with my custom firmware that fixes the above bug).

A quick rundown is when the laser SHOULD turn off, it instead remains full power, which at the end of a project when the laser stops to move up, can cause fire. More information can be found in the following two posts; one of @VaporPhoxxe’s observation, and my response to the cause.

It seems like updating to the latest firmware should resolve the issue


That’s good then, least it got resolved quickly.
