Great news Don!

If you keep seeing that error dialog window, high light all of the text in that small window and paste here so I can read it. Do you recall what you did the last time you had BCL open and then you closed it? It's probably related to what you did just prior to the start up where you saw the error dialog message.

Let me know if this continues and if the laser beam continues to fire upon BCL start up. I may have to do a with you to see what is going on with your BCL.

>and have some idea now of what Ralph has put into his program.

Paul Henty is the co-developer of BCL. He has added a lot to the laser graphics capability and he also wrote the Virtual Laser Machine (VLM) for BCL. The VLM is perhaps the greatest feature of BCL. It is truly a Virtual Laser Machine.

Those new test shape burn lines now look good. Thin and sharp, as they should be, for a 2.5 watt laser.

When you purchase the full version of BCL, all your laser tools will still be there. They will not be over written. Same for all of your settings, etc. Your configuration files do not get over written. In other words, you should see no changes other than the top title bar displaying Paid Version.

Remember, BCL is always installed into the same folder: BenCutLaser.

A 2.5 watt laser should burn a line thinner/smaller than that.

You need to focus your laser beam. See my video tutorial #3 and focusing starts at 27:33 in that video.

With BCL you burn a test focus line, then turn the lens (make an adjustment) and then burn another line. Make an adjustment. Burn another line.

DO NOT make an adjustment while the burning a focus line. Adjust only when the laser is OFF. Otherwise, you'll burn your fingers!

Let us all know how you make out!

Glad to hear you got the toolpath issue working OK. Good job!!

Just curious on the SW problem. You do have the radio button selected as shown in the attachment? That is the only way to get the g-code to go out to the laser machine.

If you do have that radio button selected as shown in the attachment, then the next step will be for us to link our PCs together via so I can have a look at your BCL setup/configuration, etc. I'm on Los Angeles time and am available anytime so just let me know what time works best for you!

Merry Christmas and Happy New Year to you too!

I think we'll have to link up via so I can see more of your setup and configuration in BCL.

What time zone are you in? I'm in Los Angeles. Let me know when we can link up our PC's.

>Do you have any advice for the BCL3.2 SW hang-up problem?

Without knowing more about your laser machine setup, no, I don't. It's hard to guess. That's why I asked you for the information in the link in my last post to you (which you did not provide). I don't know if you're getting the correct Welcome Message. I don't know if you're using the correct .NET Framework version. I don't know what language you are using. I know what firmware you are using but I don't even know what kind of controller board you have. This is important. You have to help me to help you, otherwise all I can do is guess as to what might be wrong. We can go through some basic testing but I still need to know more about your setup so I have an idea of where to focus my attention.

It's human nature to just say this doesn't work, why, but I need more information to trouble shoot your problem. What you've done is like taking your car into the shop and say "it doesn't work", can you fix it?

Regarding your toolpath, did you make sure all the Splines were flowing in the same direction? I see many that don't 'flow' in the same direction and they each need to be 'flipped' so all are pointing in the same direction/flow. See attachment.

Hi Wolf

I downloaded your .dxf file and it loads fine into BCL. No warnings, no errors. See attachment. I ran the dxf checker in Setup and it passed all tests. I don't see any issues with the dxf file. However, I have no idea what your toolpath looks like to trouble shoot that problem. I would need you to tell me how you created your toolpath so I can try to duplicate it.

The g-code .nc file is also fine but obviously not related to the dxf file. I ran it in the BCL Virtual Laser Machine (VLM) and it ran perfectly fine. See attachment.

I need a lot more information about your system. Please review this post:,1128.0.html

Thank you...

What language do you have set?

Try setting English language and see if that makes any difference.

>I've tried on 3 computers, 1 license 2 trials, W7 and W10, none works, all are in french but changing language seems to have no effect.

Verify you are using Grbl 1.1e correct?

You were able to successfully flash Grbl 1.1e to your smoothie board correct?

Please do these tests for me:

(1) Start up BCL but do not connect it to your laser machine. Do the same Circle test and send it to the VLM (with no connection to your laser machine).

(2) Now, connect BCL to your Smoothie board and screen shot the Com Port tab. I want to see what you getting for a 'Welcome' message.

I'd like to see what you get if you send your Test Shape to the VLM?

Can you send your Test Shapes to the Virtual Laser Machine (VLM) and post those images? On tab 2, Laser Tool Parameters, just check the Redirect g-code to receive window and then also check the Send g-code to VLM checkbox.

My Test Shape attachments are attached.

Note the Ralph3 file: Line 5 in the VLM shows a different laser power command in my setup: M04 g-code word is being used, the P0.5 power command is of lesser importance.

When you select the Smoothie or Cohesion boards, BCL will automatically use M4 (replace the M3 word) for the laser power g-code word. But I don't see that happening on your setup.

For now, you can focus on using the VLM. If you can't get the correct g-code output going to the VLM, then there is no need to waste time sending the g-code to your laser machine. The VLM g-code is EXACTLY what will be sent to your laser machine. So if we can get your VLM working with the correct g-code, then it WILL work when sending to your laser machine. So, let's focus now on sending to the BCL VLM. This is what is was made for. Trouble shooting.

You are 8 hours ahead of me, which is fine. It's 7:20 am here in Los Angeles now so it's 3:20 pm for you. We can link up when you're ready and it'll be in the morning for me and the afternoon for you!

The Mana SE board is fine. That's a great controller board. What version of firmware did you flash into it? You should be using Grbl 1.1e which is provided by me (the file is installed for you to grab when you flash the board with it) when you install BCL. But you have to select it and flash it yourself. Flashing means 'installing' that file (Grbl 1.1e) into your controller board. You can use BCL to do that as an FYI.

Please contact me here when you get your parts and your laser machine is up and running again. We'll get this sorted out. You want to have the trial version working to your satisfaction before you make a purchase of BCL.

It would be faster if we could connect our PCs together using I have a lot of questions and rather than going back and forth here, it would speed things up if I could see your setup and ask some questions.

Normally I ask that folks provide me with a set of answers to the questions I want to know about up front so I have a base line. We can address those questions and answers when we link up our PCs and then I don't have to assume or guess anything about your setup.

I'm in Los Angeles so please let me know what date and time would be good for you to link up and we can get this resolved sooner rather than later.

The questions I ask are located here:,1128.0.html

So please review and have your answers ready when we link up. At this point I know nothing about your laser machine, what controller board you are using or what firmware you are using, etc. G-code that is generated will depend on your selected controller board and how you have configured your g-code words in setup.

Thank you for helping me to help you.

Firmware you are using?

Screen shot of your setup tab showing your controller board settings?
