    • RE: Configure Laser Co2

      Good morning,

      First of all I want to thank all the help I'm getting, but it's not working for me, I think the installation is correct, and I apologize for what could bother me with so many questions, but I would not like to leave the project.

      I will explain my approach and the duas.

      The first thing is to check the installation I have is the correct one, or I would have to change to option 2 or some other cable. The PWM always goes through a converter board

      My installation (Duet - Laser power supply)

      FAN0 - FAN0- <> Signal Ground GND
      FAN0 - V_FAN_A <> Imput Control Signal (0-5V)
      E1 HEATER - E1- <> Switch Laser Control (Active Low)

      I am asking if option 2 would be more correct, connect E1 HEATER - E1- <> Imput Control Signal (0-5V)?? and activate "Switch Laser Control (Active low) with another PIN that acts directly on/off with M3/M5?

      I pass photos:

      alt text
      alt text
      alt text

      E1 may be doing PWM by the Switch Laser Control (Active Low) PIN
      from the laser power source?

      Is this Gcode format correct?

      G1X4.72S51
      G1X0.06Y-0.1S0
      .........
      ..........

      I've been looking at this post, but I think it was talking about K40 and yet I think this laser power supply, could it be connected differently or am I on the wrong track?

      Thank you very much again

      @EASYTARGET Thanks for answering.

      I've been installing and testing and that's why I've been slow to answer.

      LaserWeb, generates a Gcode without the G1 in front of each line and the Duet, does not respond to these movements. For the rest, it seems that it could be worth it, but without that, it does not move in conditions. Step example of what it generates ...

      G1 X2.15 Y2.15 S0.0000
      X21.95 S0.3129
      Y2.45 S0.0000
      X21.80 S0.6872
      X2.30 S0.7000
      X2.15 S0.4841
      Y2.75 S0.0000

      Those lines are not valid for Duet.

      Let's see if someone can help me, because I think I'm going to have to leave Duet for the Laser.

    • RE: Configure Laser Co2

      Hello,

      We are a group in Spain of more than 20 people, we have mounted a CO2 laser and mine, is the first that is working. We have installed Duet2D Maestro and we are looking for a software that generates a Gcodec completely compatible with Duet and the Laser.

      We have acquired some already LightBurn, but we are not having good results, we do not know if the culprit is the adjustment of the Duet or it is of the Software, since with a Laser K40 and plate of very little quality, it was obtaining better results with K40 Wisperer.

      Maybe we have to make some adjustments or change the software.

      Could you make some recommendations?

      Thank you very much.

      P.S.: Sorry, but I don't know English and I use Google translator.

    • RE: Configure Laser Co2

      I tried Ligtbrurn with the Smoothieware profile and generated the Gcodec that I put next. Is this seriously correct? Can something better be done to get more performance when recording with the Duet with other software?

      @dc42 Very funny and sorry that I have to bother again, but something I do not understand.

      You are not sending the G1 command with parameter S1. Or I did not understand something.

      I send a piece of a Gcodec, to tell me where the error is, by using the M3 command with the S1 parameter that Gcodec, or do I have to modify something in the config.g ????

      Ye have modified LightBurn and the code comes out with the M3, as I had indicated. Send example.

      My question now is ... to fire the laser, I have the PWM of the fan controlling the (IN) Imput 0-5 V.

      What output do I have to connect to TH of the laser power supply ??? GND H2 ??? or positive + H2 ???

      Thank you.

      P.D .: Sending photo connection of the power supply

    • RE: Configure Laser Co2

      I had to do Downgrade at 2.04, and before starting to do the job, I have to send by console M3 S255, to turn on the Heater, and that is how it works. Otherwise or just sending M3, shooting does not work. I don't know if something will be wrong.

      Thank you

    • Configure Laser Co2

      Hi,

      I have configured a RepRapFirmware for Duet 2 Maestro 3.0 (2020-01-03b3), and I need the H2 to perform the diparo through the GND (-), but it is not activated. I pass the Test File and the config.
