Laser turned on on all moves.

edited February 15 in Questions & Answers
Hi all,

Hope someone can help me. I'm doing some testing in laser mode but i don't get it. After selecting laser mode and during g0/g1/g28 moves the laser pin is always going high. Tested it on D44 and D4 both with the same result. Did also try a test script with the same result. Running version 1.0.0dev. Also in printer mode the pin stays low during moves.

g28
m452
g0 z400
g0 z300
m3 s0
g0 z400
g0 z300
g0 z400
g0 z300
m3 s255
g0 z400
g0 z300
g28

Some results on manual commands:
21:42:09.810 : N152 M452*38
21:42:09.810 : PrinterMode:Laser
21:43:20.052 : N153 M3 S0*100
21:43:20.052 : LaserOn:0
21:43:35.747 : N154 M3 S255*97
21:43:35.747 : LaserOn:255

Thank you,
Arjan

    why do you move Z in laser operation? (Laser gets not activated in z-move and also not in g28 and G0 moves)


    (if laser on/off is swapped change  from #define LASER_ON_HIGH 1 to #define LASER_ON_HIGH 0 in configuration.h)

    try as follows:

    M452

    G28

    M3

    G1 X100 F200

    G0 X0

    M5

    from configuration.h :

    /*
    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 intensity 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.

    Turning on laser mode and doing z moves is not strange in my opinion. I have a delta printer and i can image that you change the height to burn the next layer (change the focus point).

    Also in my case m3 s0 or m3 s255 and m5 gives all the same result for all moves! Laser is turned on.

    Also laser is turned on during the whole time in this script no change at all!:
    m452
    g28

    g0 z400
    m3 s0
    g1 x100 f1000
    m3 s255
    g1 x-100
    m5
    g1 x100
    m3 s255
    g1 x-100

    m3 s0
    g0 x100 f1000
    m3 s255
    g0 x-100
    m5
    g0 x100
    m3 s255
    g0 x-100

    so as nothing changes at all... seems your wiring is the problem.
    i have laser working  without any problem. refer text from configuration.h

    Wiring? I just measure the state of my D4 pin. So it must be a software thing.

    some more informations of your setup would be useful.....
    which controller do you use (f.e. ramps or something else)
    check pinlist for double use etc.

    software(dev version) is for shure not the problem as i use it .

    No problem, i use a ramps board 1.4. Good to know that you are using the same version. Tonight i would also try the light pin because that one is working for the light and re-assign the light to another pin in the config. Also i have chosen D4 because of the PWM support.

    This is my current configuration.h:

    ok, as i work with Due i can´t check directly, but ihave a ramps board free so i´ll try to set it up tomorrow to check your setup.
    (even i don´t have the controller but that shouldn´t matter)

  • edited February 16 Posts: 0
    so i´ve set it up , just downloaded fresh dev. version and copied your configuration.h in it.

    i just connected a led with series resistor to d4  for simulating laser

    as expected , it works. are you shure your mega is ok?

    only thing i see problematic is the memory warning in compiler and for me it looks like not running reliable depending on memory.
    But as i´m not familiar with deltas i have no idea what and how to optimize

  • edited February 16 Posts: 26
    Thanks for your effort. I have the same memory warning for more then one year.  But I 3d printed a lot of stuff without problems. So i expect that is not my problem. My mega could be wrong, but on the other hand my dual extruder works, heated bed, lights,  end stops, lcd... and i tried d4 and d44. But i will also tryout some other pins just to make sure. But it's also strange that the pin is going high only during movement and only during laser mode. And in all other situations just low. I will do some more testing. 

    Ty.

    thats exactly what it shall do.....!!!
    if it stops and laser would be on you would just make things burning.
    it´s wanted that laser is on only during moves
  • Posts: 26
    but also during the g0 moves
  • edited February 16 Posts: 26
    And in my case i cannot do a move without laser turned on. A possible workaround would probably be switch from printer mode  to laser mode all the time :-)
  • edited February 16 Posts: 0
    i rechecked and also saw that now ,also no reaction on m5. but in this case i cannot help so gcode is same for all drive systems.
    when i set drive system to 0 everything is ok.but not useable for you

    may be you start a bug report for delta system for this case.

    btw, if you set m3 s0 before go move and m3 s255 before g1 move it should work, but thats not the way it should



    so found the time for short crosstest.
    switched my due testsetup over to drive system 3 and that works like a charm...
    g0 switches off , g1 on  m5 also switches off correct.

    so if not memory related there might be a bug in avr-version, i´m not shure
  • Posts: 26
    In my script above i tried everything. m3 s0 and also m3 s255  both in combinations with g0 and g1 all with the same result.

    seems to be memory problem.
    i checked the code which is identical for due and avr and as it works perfect on my due also in delta mode i think it´s
    memory problem on the avr.
    but maybe you start bug report as the not correct working behavior is reproducable
  • Posts: 26
    Will try to analyse the source code first. Maybe i can find a clue there.

    already merged avr version vs due version. no difference

    This seems a bit unlogical:

       #if defined(SUPPORT_LASER) && SUPPORT_LASER
       else if(Printer::mode == PRINTER_MODE_LASER)
       {
       p->secondSpeed = ((p->delta[X_AXIS] != 0 || p->delta[Y_AXIS] != 0) && (LaserDriver::laserOn || p->delta[E_AXIS] != 0) ? LaserDriver::intensity : 0);
       p->delta[E_AXIS] = 0;
       }
       #endif



    In combination with this:
            case 452:
    #if defined(SUPPORT_LASER) && SUPPORT_LASER
    waitUntilEndOfAllMoves();
                Printer::mode = PRINTER_MODE_LASER;
    #endif

  • What is here unlogical?
  • edited February 17 Posts: 26
    the else if statement. Now c is not my native programming language, so i could be mistaken ofcourse. :-)

    Looking longer at this code i think this is not the problem. Sometimes a bit hard to read c code. I thought that the else if was a part of the if statement but it is not. Still no solution :-(

    Luckily weekend is coming up :-)

  • #if is a preprocessor if and decides which code parts get compiled at all. The following else is part of c++ logic. SO watch out for # signs indicating non c++ but preprocessor statements.

    Thank you for the answer, i understand now why. Just to make the final code shorter.

    I really don't get it. Switched the pin number of the laser and the case light to see what happens. This is also very pleasant because now i can see easy when the laser is on (case light). But the problem is the same, during all moves it stays on.

    What happens with this code:

    g28
    m452
    m3 s0
    g0 z300
    m3 s255
    g0 z400

    The light turns on, homing starts and flickers during the multiple end stops hits, moves to z300 and z400 with lights on and then the lights go off.

    Added also comment output to all changeIntensity calls. And almost during all moves the repetier.h calls the changeIntensity(255). I think i'm going to use the fan pin. Because this is not working at all for me. My added comment in the repetier.h file:

    if defined(SUPPORT_LASER) && SUPPORT_LASER
            else if(Printer::mode == PRINTER_MODE_LASER)
            {
                Com::printFLN(PSTR("Added for testing, change intensity to 255 (2)"));
                LaserDriver::changeIntensity(255);
            }
    #endif

    :((
  • I don't understand it. G0 has laser off so it should not be on. So you are using wrong pins or pins are used for other functions as well so they get enabled. Something like that.

    Still strange that RAYwB was able to reproduce the not functioning m5 command. Running my delta on ramps 1.4.
  • Haven't seen that comment. I see M5 sets laserOn to false and adding moves uses this condition:
                    p->secondSpeed = ((p->delta[X_AXIS] != 0 || p->delta[Y_AXIS] != 0) && (LaserDriver::laserOn || p->delta[E_AXIS] != 0) ? LaserDriver::intensity : 0);

    so essentially setting intensity 0 if laser is off. And G0/Z moves also have always laser disabled. And from your description nothing of this is happening in your case.
  • Thanks to a hint from RAyWB I found something. Just fixed dev version. For deltas laser was always set to 255 and not secondSpeed which is what we set in M3/M5. Should now work much better I think (please test if possible).

    I was just starting to migrate my firmware to the m106 setup. But i will give it another go, will keep you updated.
  • edited February 19 Posts: 26
    Working now as designed! Thanks for your effort! So no wrong pins etc ;-) the problem was exactly in the code i pasted above only i was mistaking the file it was in (was a bit hard to see what file was open due to the many tabs).

    But after all this testing i'm wondering why would i not go for a fan pin so i have pwm and the ability for greyscale? Less code in memory. Are there any drawbacks?

    Regards and thanks again!

  • Fan does not change between G0/G1 and is always on while G1 will enable laser and disable at end for safety etc. So the laser solution is the one you want. It is easy to mod it a bit in driver.cpp where you set intensity. There you can also call analogWrite(pin,intensity) if it is a hardware pwm or set the fan speed there. Fans get a 16Hz signal so it is more like a dotted line maybe, depending how much frequency the driver needs to set power. I somehow assume you need a high frequency to do grayscale.
