No voltage output on D10 pin while G1/G2/G3 command in laser mode
Hello,
I use Arduino Mega 2560 and Ramps 1.4
I use Repetier-Firmware configuration tool to set firmware on my DIY-SLS-3D printer. It works well with motor control but when it comes to laser:
I have no voltage output on D10 while I use G1/G2/G3 code, so setting laser power has no influence
I use:
G452 //set firmware to laser mode
M3 S150 //set laser power for example to 150
G1 X100 //it only moves to X100 but laser dont work while this.
Can anyone help me?
Also here is URL for the project I've followed

G-code M5 (spindle off) doesn't work to.
I guess it is a problem with voltage output on D10 pin but maybe i i'm wrong? How does it even work?
I measured voltage on different pins (D10, D9, D8, servos pins) searching for some laser stering signal during G1 X100 command, but without any possitive effect.
On my repeatier host I can see that machine understand G-code correctly, It is in laser mode, it changes laser power with M3 S255 command. Everything looks good, but the laser output (D10 on ramps, used for extruder heater) always show 0V.
I tried to use different pins in ramps, for example D8, D9 or D11 (servos pins). In laser mode it always shows 0V.
I download standard FDM Repetier-software to check if its not a hardware problem (with RAMPS 1.4 or Arduino) and it's work well, for example I see 12V on D9 output and it changes when i change fan power.
In laser mode I use it only for laser output.
Now I added new extruder, but... What pins should I choose for "temperature sensor pin" and "heater pin"? What's an extruder role in laser mode?
And yes you need to modify firmware to us ethe laser correctly in laser mode etc. so it only is enabled on moves, ...
In V1 you have no hardware PWM for laser. You can modify the code to do so as discussed in several threads here in forum. But for cutting you just need a matching speed. Hope inkscape plugin still works. I think a update of inkscape made it non functional as it created wrong sizes:-(
What I mean is in configuration.h set 10 as pin number for the fan. Or better use our configuration tool to have a interactive configuration for V1. But creating a firmware is a bit of programming. You configure a software source code compile and upload it, so basic understanding helps especially on errors.
I never made grayscale drawings so never testen any software for it. It is on my long todo list, but being fdm software provider in first place that is not highest priority.
