Trouble Shooting / Re: total noob, machine wont work

Is the laser always on still or is that resolved (when "weak" button is NOT pressed).

What happens when you click the jog arrows? Do you hear the motors making noise?

Welcome dalesdeadbug!

OK, let's start with the easy one - do you have the "weak" button pressed?

If not, when you installed the firmware are you sure you selected the correct one? If you loaded Grbl and not the Eleks firmware that would cause the laser to stay on. Check the firmware section where I've posted the common files.

If that's not it, make sure you have the parameters in Benbox set for the correct laser pin.

The other thing to check is the jumper position, it should probably be set to 0.8 if you are using the default settings - it's under the Nano, so you'll have to carefully remove it (make sure you take note of it's position as there are 2 extra holes in the socket).

I've been beta testing the latest code and fixing bugs, it's a slow process.

I also received my Eleks L6 V2 board that supports limits and other features, so plan to do some testing with that next week.

Yes, I agree and its very easy to implement so I will add to the next version.

That is correct, the Sketch dimension is the page size. When you visualize the G-Code later it will scan and show the extents.

It would be simple to add an edit function, but I do not currently have it. If you manually change the G-Code it may no longer work, or not work correctly. T2Laser knows what commands Grbl or Benbox accept and creates the correct G-Code.

T2Laser itself doesn't care what commands you use, but if your firmware doesn't support them it will just cause an error and malfunction. Check out the Grbl github pages for all codes it accepts.

Trouble Shooting / Re: Focus problem (or is it?)
« on: May 06, 2016, 05:29:09 AM »
The jumper just changes the laser "on" signal to a different pin on the Nano, since the developer wanted to add PWM support for CNC spindle speed control.

If there's a newer version of Benbox firmware that supports PWM then it should work with any laser head. T2Laser supports the Benbox firmware that my machine shipped with, so if there's an update I'd like to try it. Where did you download it?

I use 0.1 and it keeps the details, you just get more small segments but T2Laser deals with those OK.

The 5.5W laser module appears to have a built in low power mode, I'm not sure how this works as I only have the 2.5W system.

It is not firmware or software related, so must either be from the laser current driver mounted on the laser head or something with the Eleks board. Perhaps someone with the 5.5W could measure the output voltage from the Eleks board and see if it is always on, or does some level shifting to enable low power mode.

As others have said, your only option is to switch over to Grbl 0.9 and use my software or Ralph's when it is released, obviously depending what you want to use the machine for.

You have the latest stable version, but I have also been providing release candidates which are beyond beta testing but may still have some bugs. The latest is v1.2e, I have plans to do some additional updates next week, including a basic raster to vector tracing function.

See my signature for links.

What you describe, sounds normal for a standard Benbox 2500mW system.

No, unfortunately the international language support part of Microsoft .Net is only available for Frameworks 4.5 and they don't support that on XP.

It takes some additional work for me to compile a custom version using Frameworks 4.0 as I have to remove sections of code that aren't supported but I do plan to do that for major releases.

There are several threads on this, but with Inkscape you must convert objects to paths and also flatten Bézier curves. Then export in mm and everything will import correctly.

I used the CO2 due to it's speed and since they were mixed colors it just performs better (more consistent results). No rotary axis, I did one side and then manually rotated them 180*. I built a simple jig to hold bottles at a time, but it still took some time and patience but was worth it.

There is no reason you couldn't get similar results with the diode laser, as jlauzon has shown.

Thanks for posting Sir-James. I'm sure these settings will help others as a guide to get started, and your cork coasters look great.

@eodguy, you really aren't losing anything for engraving but if cutting is your thing - more power means less passes and faster results.
