And your assumption is that a very low PWM signal – to weak for the laser to turn on – is somehow identified by the board on top of the laser head to activate the fan? Also remember any in the base, although 'head' suggests not) and all looms etc connect back to the control, then the issue could be components in the driver/sense circuit or less likely firmware glitch. Using the S9 board, you can take the grbl firmware and integrate any temperature-control code you like (if you are able to integrate it into the grbl source code base).

Will take a look under the S10’s hood then and post a picture of the board here when I find the time. Additionally, I don’t see any direct way fan signals would be sent with the pins on the laser module for V, S, GND (12V, Signal - PWM, and Ground). I suspect for Ortur laser modules they’re designed to have the fan on anytime the laser is being commanded through PWM.Some of the technologies we use are necessary for critical functions like security and site integrity, account authentication, security and privacy preferences, internal site usage and maintenance data, and to make the site work correctly for browsing and transactions.
