"Cool down delay" between passes
« on: April 25, 2017, 04:34:33 PM »
There is a cool down delay option in the T2 settings sub menu. 

How much burning (time or power level) would cause enough heating to require a cool down between passes (any formula for time vs power level)?

How long a cool down period is reccomended?

Will "air assist" make any difference by providing extra cooling to laser?

If the laser is overheating you might want to wire the cooling fan to be always on. On my unit, the fan ON follows the laser ON signal.

It isn't necessary if you have sufficient heat sink and fan for the laser. There are some smaller modules with 2.5W or higher diodes that get hot when running continuously, in that case a cool down delay would help.
