T2 Engraving / Re: T2 Laser and Convert2DXF
« on: December 03, 2016, 03:13:26 PM »
So I tested out the CLI version of Convert2DXF. It works well except for one thing. Attached is the PDF file I am trying to convert as well as a snapshot of the error I get from T2L.

Any ideas? What am I doing wrong?

So....you're saying I am a blockhead.............. ;D

Wow. That is an easy fix. Use the correct app. I will try that when I get back to my laser computer.

That's why I said donations. He is giving the software away for free, people just should be given the option to donate for his hard work. Once I get my laser computer OS issue handled and when my new L7 controller board arrives, I will most definitely be buying T2L.

Thanks!

T2 Engraving / T2 Laser and Convert2DXF
« on: December 03, 2016, 08:27:59 AM »
Hey Zax and Agastar. Right now I have the trial of T2 Laser (still picking a fixed computer for my engraver and only want to buy it once if I can  ;D) and Convert2DXF.

It looks like an awesome project but I found two issues when using them together.

  • When I use the Convert2DXF stand along and set it to T2L Mode, T2L cannot open the dxf file. The error says "No Supported entities were found, unblock and convert to segments"
  • When I try to use Convert2DXF through T2L, like in video #4 of the Starter Series, I click on "convert PDF", it tells me to find Agastar's Convert2DxfCmd utility. I then find it and click ok, as in the video. Now when I click on "convert PDF", it asks me again to find the utility.

I don't know if this is because I have the trial version of T2L or if there is some errors arising between versions of both programs.......or maybe I am just a blockhead  :P.

Any help is appreciated. I love what you guys are doing. Agastar, you should throw in a paypal donation option for your app either through the app or here on the site.

General Discussion / Re: Board Differences

Thanks Zax. Your explanation and the accompanying pictures help a lot. I am starting to see why you recommended the L7 board to me. I love the "week" laser. I have a L1 clone from the kit i bought from a lady and it is spelled wrong as well.

If they are all "eh" in quality, is there a better (probably not cheaper) board to go with? Has anyone on the forum designed a compatible board that is bettery quality?

Can anyone explain the differences between all of the Eleks board revs? I know of L1-L7, but don't know where to begin on finding the differences.

T2 Engraving / Re: Eleks Maker L1 Board T2Laser Firmware and PWM
« on: November 26, 2016, 08:17:55 PM »
I "think" that the grbl 9 code is going to setup and use PWM on D11. On the AVR chip this is not available on D12. If you are not going to drive the laser then:

   1. Initialize D12 as an output.
   2. Assert D12 low.

Make sure that D12 is never changed to an input. The PWM will still go to D11 which I assume is not routed on your board.

You could generate random numbers and use that to drive the laser and then tell Zax that his program is flaky.

Yeah. I would rather do the hardware fix and have PWM.

Being that I have a clone board, I will not say Zax's program is flaky. He has been a huge help with hardware that is not standard. I can't complain. Don't know if you are robbing him with this, but I am serious. This forum has been great for someone like me just coming into he laser world. Everybody has been very patient and helpful.

Thank you everybody for letting me be part of this group. I will always help where I can.

@Zax

Don't worry about it. The benbox firmware works well enough with T2. Also, with the board limited to black and white, the benbox software will work just fine as well.

I just played around with T2 and it works well enough. No need to put the additional labor to recreate existing firmware.

When springtime rolls around and the temperature is decent, I will mod this board out to work with your T2 software.

Also, I have a win10 machine that is not activated. I am going to see if I have to activate it or if I can just deal with pop ups. I can deal with ads  ;)

I appreciate it. Any way I can get it non-hex as well so I can go though it to understand it more?

I am going through the grbl code now. Would it help if I just commented out the lines in the cpu_map_atmega328p.h file where the if/else statements for the VARIABLE_SPINDLE is mentioned. It seems like that is what sets the Arduino pin to D11 or D12. I could just force it to go to D12. Do you see any problems with that?

Hey ggallant571. Thanks for the reply.

I will have to take my board off again to confirm that it is indeed on D12.

In reply to your options:
1. I would cut it, but the weather is cold enough to make my hand shake while soldering (don't have a heated garage......yet)
2. I would love to do this. I have the firmware from https://github.com/grbl/grbl but am still slogan through it to see what
    I need to change. I have the variable spindle disabled, but am still missing something. Any help in this matter would be greatly
    appreciated.
3. Oh boy, am I waiting.
4. I will have to check that out. I love DIY
5. True. Could be similar to #2. Again, I can work my way around the code, it is the meat (g-code) that I am still learning.


I would love to have firmware for both boards. That way I always have a backup, even if it is more limited. Who knows, maybe my L1 board will go on another CNC that I build from scratch. options......options.....

Just tested with the 0.9j custom firmware. It works but the laser does not turn off.

I attached a picture of a partial engrave.

If that is the one included with T2, then yes. If not, can you point me in the right direction to download it?

OR.....I could have looked at this post http://benboxlaser.us/index.php?topic=16.0.

I commented out the variable spindle, but my laser still does not turn off.....

Thanks Zax. I know this is more of an exercise in futility being that I am getting the L7 board, but I would like to have some firmware that will work well on the L1.

Just to confirm, comment out all parts of the code referencing variable spindle in the spindle_control.c file?

Also, where do I enable the laser?

**EDIT**
Ok. Never mind on the spindle_control.c file. I see where I can comment it out on the config.h file.
Still curious on the enable laser....

Oh, I have played with Arduino. At least my UNOs, mini pros and MKR1000 think so. I know my way around Arduino. Now, where I am confused is where I get the GRBL code. Just get the code from GitHub and make my edits?

Is the 0.9g and 1.1c your versioning system. I just want to make sure I end up editing the correct base code before I edit and dump it into the nano.

For some background into, I understand Arduino decently, work with Raspberry Pi quite a bit. I can program both, but am not an expert at either. Just enough to be dangerous.

General Discussion / Re: Are the green glasses from Chinese kits safe?
« on: November 25, 2016, 09:49:56 PM »
So, the glasses got delivered. They fit really nice and work pretty well.
They came with nice hard cases and cleaning cloths (see picture).
I highly recommend these. I put the cheap green glasses for comparison.
