No voltage output on D10 pin while G1/G2/G3 command in laser mode

rdzawka · January 2019

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
https://www.instructables.com/id/DIY-SLS-3D-Printer/

PWM for laser is not implemented in Firmware, so values lower than 200 are interpreted as Laser OFF and values >=200

are interpreted as Laser ON.

There are several Threads here in Forum regarding Lasers.

If you want PWM for Laser you have to write your own Driver

Well, i tried set M3 S0, M3 S50, .... , M3 S255 and i can't see any difference, laser is still on no matter I move X/Y axis or not, always on.
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?

RAyWB · January 2019

so may be you should check your wiring and for tests use a simple led, not the laser.

just for safety reasons

BTW Lasermode is set By M452, not by G452

rdzawka · January 2019

Of course I don't do my tests on laser since I've noticed that it doesn't work correctly.

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.

you cannot double use pins. if it´s used for extruder heater in fdm mode you cannot use that pin for laser in laser mode

rdzawka · January 2019

I mean it is usually used for extruder heater on Ramps.
In laser mode I use it only for laser output.

RAyWB · January 2019

you should share your configuration.h so we can see whats going on

Here is my configuration.h file:

/*

If the firmware is in laser mode, it can control a laser output to cut or engrave materials.

Please use this feature only if you know about safety and required protection. Lasers are

dangerous and can hurt or make you blind!!!

The default laser driver only supports laser on and off. Here you control the eĂntensity with

your feedrate. For exchangeable diode lasers this is normally enough. If you need more control

you can set the intensity in a range 0-255 with a custom extension to the driver. See driver.h

and comments on how to extend the functions non invasive with our event system.

If you have a laser - powder system you will like your E override. If moves contain a

increasing extruder position it will laser that move. With this trick you can

use existing fdm slicers to laser the output. Laser width is extrusion width.

Other tools may use M3 and M5 to enable/disable laser. Here G1/G2/G3 moves have laser enabled

and G0 moves have it disables.

In any case, laser only enables while moving. At the end of a move it gets

automatically disabled.

It also can add a delay to wait for spindle to run on full speed.

Think the problem is that you have not defined a extruder.Even if you don´t use it as Printer it´s still a printer firmware.

May be i find the time the next days to setup a ramps/mega to test

rdzawka · January 2019

Ok, You were right. I didn't have defined extruder.
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?

Repetier · January 2019

You can select fake temperature sensor and heater -1 hopefully works meaning you have none. That makes it a tool without extruder function.

rdzawka · January 2019

Thanks for your response RAyWB and Repetier. I defined extruder and now everything works like it supposed to work in laser mode,

Thanks for your help!

Filusico · December 2019

Hello

I would need a hand if possible.

I purchased a 5.5W laser

and I wanted to connect it to the ramps - repetier

but I'm not a programmer and I don't know what to do.

where I have to connect the 12V (PIN on the ramps) and the PWM signal on which pin.

do i also need to program the firmware?

What should I write...?

Thank you

Repetier · December 2019

Lser differ, but if it is similar to mine and has 12V plus a TTL pin then you connect 12V to always on 12V or as I did it define a fan e.g. connected to D10 so you can control if the laser is powered at all. If it gets power you have a small light you can use to position and focus. With fan on (100%)/off you can control it. The 5V TTL pin can be connected to any unused digital output just make sure you write firmware to use that pin. As soon as it goes high laser will run full power so make sure you are not in same room or you are very good protected with special glases and a surrounding to printer. These lasers are very dangerous when enabled. Even with correct laser glases I never look into it - it just hurts the eye.
And yes you need to modify firmware to us ethe laser correctly in laser mode etc. so it only is enabled on moves, ...

Filusico · December 2019

I tried to connect 12V on the D10 (extruder output) but starting the list it does not turn on.

Do I have to manually turn on the extruder from the button?

I downloaded the plug-in for inkscape but it doesn't create a Gcode for the fan ..?

What do I control this blessed fan with?

I would like to have a PWM control, which pin should I use and what should I change in the firmware?

unfortunately I'm not a programmer I need clear info ..

Thanks so much

Repetier · December 2019

You need to assign the pin to fan function then you can control it with M106 and M107 or in any host software with fan control.

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:-(

Filusico · December 2019

I'm sorry

but I don't understand what it means to assign the pin to the fan function?

unfortunately I'm not a programmer and if you please explain to me what to change maybe I can do it.

what should I change in the configuration.h file?

Filusico · December 2019

I have read many pages here but none that clearly explain what to do.

Why don't you just tell me to edit with this text and which pin to use?

you talk to me about not being able to use PWM and that from v2 it will be possible but when does V2 come out?

Filusico · December 2019

which host fan control software do you recommend for making grayscale drawings?

Repetier · December 2019

V2 is out but the AVR support is not finished. Currently only some 32 bit boards are supported.

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.

No voltage output on D10 pin while G1/G2/G3 command in laser mode
