General Discussion / Re: Custom gcode
« on: February 27, 2018, 01:38:06 PM »
I'm not sure what you want? Do you want someone to write the entire g-code for you? Or do you have existing g-code now?

When you say 'numbers only', how do you want that done? What size numbers? Do you want the numbers in Text g-code or Splines g-code?

I don't really understand what you want here.

As far as I've know and have read, the 3.5 and 5.5 lasers have a rectangular beam shape on the material when focused.

As I suspected, there would be great interest by many if they could get their hands on a small dot focused 3.5 laser  :)

OK, @Zax will have to jump in and tell you how to send the command to display the firmware settings.

Attached is how BCL gets this information.

What software are you using?

done all that over written the t2 firmware and stillthe same result laser carriage moves in only one direction

>done all that over written the t2 firmware

What exactly does that mean? What exactly did you do?

I'll ask again one more time: It wouldn't hurt for you to dump your firmware settings and post them here.

Have you checked the stepper motor pulleys to make sure the set screws are tight? Loosen your belts so you can manually turn each pulley and make sure they are tight on the stepper motor shaft. Sometimes they come loose.

When you put your belts back on, you should be able to push in a belt 'about' 1/2 inch near the pulley to know that is the correct tension.

Something is wrong with your frame if you can't move your laser head to burn a circle.

It wouldn't hurt for you to dump your firmware settings and post them here. I believe T2 can do that and BCL certainly can do that. Something is just not set up right on your system.

ive done all this im running t2 stepper voltages are right but still not working

And what voltages did you end up using?

>Ralph, The focus burn line is about like a paper cut.

You have a 3.5 watt laser diode? I've never heard of a 3.5 or a 5.5 watt laser being able to burn a line that thin. I can do that with my 1.6 laser but not even my 2.5 watt laser can do a line that thin. If you have a 3.5 watt and you can in fact burn a focus line that thin, you would be doing this community a favor by posting a photo of this. No one around here has ever seen that done.

>One thing I believe about the long focal length is the fact that you should have a little more +- vertical distance before the beam gets out of usable focus.

The + - should not be an issue at all. Once you have set your focus, that is the distance and it should not change. So what does it matter re a + - value? It should be a non-issue.

You can use T2 or BCL to send g-code commands to your controller board.

You can also use UniversalGcodeSender or Gbrl Controller. Both are free.

BCL installs UniversalGcodeSender for you in it's BenCutLaser folder. It is a .jar file which means your PC needs Java installed. If you have Java installed you can just double click the file to start it up.

It's probably easier to just use T2 or BCL since both have this feature built in (to send g-code commands to your laser machine).

Do a search in this forum for 'steppers' and you'll find the links with info on how to set your voltages and what they should be. There is even a Youtube video link in one of the posts.

Each laser diode has a different focusing length...the distance does not matter because you're going to try and burn the thinnest line possible. So what ever it takes in distance to achieve that.

Do a search on this forum on how to set your voltages. They should not be set that close to each other.

Make sure you're not going back to Benbox software after having tried T2. T2 requires that you flash Grbl 1.1e+ and once you do that, you cannot use that firmware (Grbl 1.1e) with the factory Benbox software. In other words, once you move up to T2 or BCL, you cannot go back to using the factory Benbox software.

Since you're now using Grbl 1.1e with T2 (you did flash Grbl 1.1e right?), for testing purposes, you might want to try BCL because it has Test Shapes that you can test burn:

Triangle
Square
Rounded
Circle

BCL also uses Grbl 1.1e. If you cannot laser burn those four test shapes using BCL, then something is wrong with your laser machine setup.

Post that dxf file so I can take a look. It looks like that might be a bug in BCL...keeping the laser beam on when it should be off.

no circles just a straight line nothing else

What software were you using to burn circles?

Can you burn a circle to see if you can do curves?
