Hi, I'm new here and to laser cutting.

Hi, I’m new here and to laser cutting. I really like this software but it would be perfect if I know how to set up cooldown time betwen passes and or operations, can someone help me?

Welcome @Dani_Martinez ​ Why you need cooldown? What type of laser?

Hi I’m using elekslaser a3 for engrave and cut plywood, I do it doing one engraving operation and several laser passes at slow pace, I do it manually because when I try to do doing several passes without cooldown the machine frezes after several minutes working

I forgot, is a 2,5w laser

@Dani_Martinez ​ I’ve never heard such an issue and sound like a hardware problem. Maybe the stepper driver are getting to hot? Also note that the laser focus need to be adjusted with each pass so it does not burn on the same spot over and over again. So if you need to do many many passes then thats not the machine you need for cutting that material.
Therea not cooldown in LaserWeb but there could be a way to create one

A more powerfull laser would be grrst but now is what I have acces to:)
Cut with many passes with colldown is a standar option in other software as T2laser :slight_smile:

A laserdiode, when operated correctly, doesn’t need cooldown pause. You either have not enough cooling or too much current.
Is the fan on top of the laser connected to the same two wires like the laser, orare there separate wires? The fan should blow permanently, not depending on laser power!

If you realy need a pause after each pass, you can write a macro with G4 P10000 (for 10s) and attach that macro to the post path makro of the operation.

Hi Claudio thaks for your help, the fan is conected as it comes from the manufacrurer, I’m not at home and cannot check right now, anyways the manufacturer states that the laser can operate 30 minutes withowt cooldown.

I will really apreciate if you can point me towards where I can find more info about the macros and how to elaborste them, thanks a lot

I had been researching with the info you give me before and ASAP I will try to send the g-code for cooldown, if someone is interested I will elaborate on the results

Set the macro as @cprezzi told, works great but P is aplied in seconds, not miliseconds

Nice that it works! You are right, on Grbl P is in seconds. On Smoothieware P is in miliseconds and S is in seconds.
