T2Laser Software - Introduction

  • @Zax When I try to load it, the following message appears:
    "Upload failed: Firmware was not uploaded correctly."

    My machine is "Laseraxe". But he also sends the same message
    When trying to put the 1.1f.

    @Juan-Carlos-Moreno-Argüello There are several version of the LaserAxe machine, the earliest one had a Nano with no bootloader so it is not possible to load firmware via USB (you must use the ICSP connector or replace the Nano). The latest machines work with default Grbl 1.1e and then there are some which need the custom firmware as they used a different pin out.

    I would see if you can install the firmware using XLoader utility, sometimes that works. Contact me via e-mail or go to benboxlaser.us for support as this forum is for EleksMaker machines.

  • @Zax I really enjoy what you have come up with and so far nothing much to complain about except for two things

    1. After the NC-program is finished the laser-commander stops responding, the status show 100% sent but essentially no buttons are responsive. The only thing working is to emergency-stop and reset.
      However, if I try to run the same program again after stopping and resetting some lines work out but then the laser just stops moving yet keeping the laser on == bad. My only solution right now is to e-stop, reset, close the controller, start the controller and go again.

    2. When the laser controller starts it turns on the laser while standing still which leads to burn-marks on the workpiece. My current solution for this is either to have the low-power button on the laser pressed, or power of the motor-driver and laser-driver when starting the laser controller.

    All this tested with the 1.1e firmware flashed from inside T2-software.

    Are these new phenomena or something that you know about?

    I appreciate you checking it out.

    #1 is not normal, there must be a configuration issue. I have a few settings that may resolve this. Disable DTR, select low buffer mode or enable the simple protocol. The laser should tell T2Laser when the motion is complete and then it will allow full control again, so this signal is getting lost.

    #2 this is a hardware issue, the laser should have a pull down resistor on the TTL line so when the input is "floating" (not on or off) it defaults to off. That is called fail safe and for a laser should absolutely be the default. If you pull out the USB cable, lose connection or the Nano fails the laser will go to max power which is dangerous. I can not fix this in firmware or software, but you can add a resistor between - and S to fix it (1 kohm should work).

  • @Zax Thanks for the quick reply.

    I will tend to #2 first since, as you mentioned, not safe currently.

    I will check on #1 according to your suggestion and get back here with my results.

    Once again, awesome support!

  • @Zax Alright so #2 is fixed quick and easy when you knew what to do. Kudos!

    As for #1 still not working, I tried all the different combinations with no success. I can try and film it so you can see what is going on. I will reflash and reconfigure the controller before doing the test just to have a clean slate.

    Following the link are a small collection of two movies showing what is going on. What I forgot to show is that after the first sequence is done the software end up in a spin-loop consuming 100% of one of my cpu cores.

    @Daniel-Wedlund The small color bar to the right of the send progress bar indicates your machine hasn't told T2Laser it is finished, also your location doesn't return to 0,0 so something isn't right.

    Is your machine a standard EleksMaker A3 or A5 with the Mana SE board and their clone Nano?

    You enabled simple streaming protocol and it didn't change? (that doesn't even use the buffer so I would not expect it to act like this)


    You may want to try a different cable or make sure the driver is correct (use the one in the Help menu). I've heard that a Windows update can load a different driver that has issues.

  • @Zax Yes, tried simple streaming before updating the driver and just tested again now with the driver installed from the help menu all with same results.
    It is the A3 with Mana SE controller got it from banggood though and judging from the looks of the Nano it seems to be a clone but looks good though...

  • Developer of T2Laser Software

    @Daniel-Wedlund I just watched your video again and I think I see the problem. You have an M30 command at the end which shouldn't be there.

    Disable that in the Design Screen, Settings / Advanced Settings menu or you can click Help / Restore Defaults.


    Also make sure you are using the Grbl post processor as that should automatically remove the non compatible commands.


  • @Zax Ahaaa, there we have it. I did have the Grbl Post processor but still M30 snuck in there... Anyway, removing the M30 from generation stage in the Advanced settings as suggested solves the problem, atleast the simple test case I had at hand... time to sleep now (Swedish time...).

    Thanks for pinpointing the issue, upvoting your post this in case it helps someone else.

  • Developer of T2Laser Software

    @Daniel-Wedlund Yeah, I just checked myself and was able to replicate the error.

    In Grbl 0.9 there was a known bug so I automatically remove the M30 but it was supposed to be fixed in Grbl 1.1 so I do not. Guess I need to rethink that!

    Thank you for bringing this to my attention. Having it enabled isn't the default but I will still fix it in the next revision.

  • Zax engraver writes System.OutOfMemoryException what is it ? firmware grbl 1.1

  • Developer of T2Laser Software

    @Zverr90 It depends what you were doing to get the warning, basically you ran out of system resources (memory) which could be due to using the wrong settings and generating an excessive G-code file.

  • @Zax I agree G-code is great !!! the engraver has made 44% of the photos and stopped and wrote OutOfMemoryException !!! the resolution was 0.1 photo 35X29 cm 3500X2900 pixels !!! This problem is not solved ?

  • @Zax Sorry for my English !!!

  • Zax What settings are best for shades of grey ?

  • Developer of T2Laser Software

    It will depend on the material and what system you have, I can only suggest you experiment with the greyscale test image or provide more details.

    It is very unusual to get an out of memory error while running, is it possible you have some other software running that is causing this problem (backup, anti-virus etc). You probably don't need 0.1 resolution for such a large image, and using 0.15 and slightly defocusing the laser will make a significant speed improvement.

  • Zax do I need to configure the firmware grbl ?

  • Developer of T2Laser Software

    @Zverr90 If you are using my default firmware, Grbl 1.1e it should be configured already.

    Do you get any errors in the message box, which would indicate that Grbl has reported an error or is it just a T2Laser memory fault?

  • Zax I see the missing steps !!! how to fix ?
