@dc42 I'll rather stay at V3 codebase.
Reverting back to 2.05 requires re-setting too many things (endstops, laser control, etc..)

No, update fails:

Hi,
Updated to 3.0RC1, similar errors.
In my earlier example (peukku.nc) error have moved to another location (bottom line).
And while lasering star last line fails.
Gcode used for star:

More debug info:
If F value in G1 F300 is more than F1015 All lines are done as they should. If i's lower, piece is missing. And if speed is added over F1200, next line starts to suffer. Hopefully picture explains better:

Still same thing while using:
M452 C"exp.heater5" Q200 S1
Here's video:

Reload of sample and config.g.
config.g.txt
peukku.nc.txt

I did more testing.
While using attached G-Code error hits in even with S255 parameter.
First square is burned ok, then on another part start and goes well until light turns off after couple moves (somewhere around line 30-32) and comes back after next move.
Using Release 3.0beta12
Sample G-code:
[0_1573400684875_peukku.nc](Uploading 100%)

Tested with S parameter -> works like it should.
I had to ask from CAM software developer is it possible. I'm using ESTLcam at moment.
Waiting answer from there also.

Hi,
Any progress on this?
I ran in same situation with following code with Release 2.04 (Duet 2) and 1.25 (Duet 06/085).
Tested also with 3.0beta12 (2019-11-02b1) using M452 C"exp.heater3" Q200.
Config is in attached file.config.g
Seems that heater3 output is turned off.

Problem solved!
NOR gate did the trick. Although I was too lazy to visit electric shop, I used arduino to flip the signal.

int buttonPin1 = 2;
int Laseron = 8;
int buttonStatus1 = 0;
void setup() {
pinMode(Laseron, OUTPUT);
pinMode(buttonPin1, INPUT);
}
void loop(){
buttonStatus1 = digitalRead(buttonPin1);
if (buttonStatus1 == HIGH )
{ digitalWrite(Laseron, LOW);
} else { digitalWrite(Laseron, HIGH); }
}

Thanks for reply Ian!

Version what I'm running at moment is
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.0beta10 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2019-09-12b1

I'll update to latest rc and check the Laser mode.
Report will come later.

Hi all,
I'm building a cnc laser with Duet2 Wifi.
All other thigs are already working but laser fights back.

Laser Pwm is connected to fan2 output, and jumper is set to 5V setting, and in config.g fans section is:
M106 P2 H-1 F200.
It seems that laser is always on with full power.
While measuring fan2 output voltage with multimeter, it is between 0-5V.
Firmware is latest.

Any tips how to proceed?
