Help with overheating Diode Laser

This is my first posting. I hope that it’s in the correct place.

Hi,
I am a relative Newbie and following a steep learning curve.
I had a 15W laser built for me in the UK, and I have found it is based on a Chinese 3018 machine.
Supplied without instructions the fan on the diode housing packed up overheated and damaged the laser.
This has now been replaced, but I am wary of overheating the unit again.
I have had a temperature sensor fitted to the outside of the diode housing which I am able to monitor.
I had to re-install the GRBL, and have as follows:

Grbl 1.1h [’$’ for help]
[MSG:’$H’|’$X’ to unlock]
ok
[MSG:Caution: Unlocked]
ok

$0=3 $1=25 $2=0 $3=5 $4=0 $5=0 $6=0 $10=1 $11=0.010 $12=0.002 $13=0 $20=0 $21=0 $22=1 $23=0 $24=25.000 $25=500.000 $26=250 $27=1.000 $30=1000 $31=0 $32=1 $100=80.164 $101=80.164 $102=250.000 $110=25000.000 $111=25000.000 $112=500.000 $120=5000.000 $121=2000.000 $122=10.000 $130=550.000 $131=330.000 $132=200.000 ok As you can see, I am using the latest Grbl 1.1h, with the latest Lightburn version on a windows 10 Laptop dedicated for the laser. My Problem. Not wishing to overheat the diode again, I have been pausing the cut when a temperature of 30 deg C is reached. Since the last upgrade the Pause/Resume button has been very temperamental, often not resuming after a 5 minute rest. I notice from other conversations that screen savers have been mentioned, mine is off. Can anyone suggest what I can do to restore the Pause/Resume button, and also what the temperature of the outside of the laser diode unit should run at. Many thanks in advance

The issue with Pause / Resume is fixed for the next release.

Thanks for that.
Do we know when the next update is due?

The answer to this question is always “when it’s ready”. We don’t give hard dates, because software is unpredictable so they’d be meaningless anyway. We have a couple things that are new and being tested now, and hoping to release within the next couple weeks, but that’s about as accurate as I can give you.
