EleksMaker Mana SE / Re: Another TTL Module Question
« on: June 23, 2020, 06:58:52 PM »
OK, thanks.  I was looking at the pin voltage, and wasn't sure what the PWM voltage would be on the laser socket. The laser's currently running off the "other" port.  Do I have to do anything to re-map it, or are they all firing the same signal? I'm using BCL (sorry Zax!).

Thanks for the confirmation!
Just to be clear (I'm a belt-and-braces kinda guy), since my board is a little different from the one Zax posted, I'm going to be using the GND and PWM pins from the Servo port (circled), correct?

EleksMaker Mana SE / Another TTL Module Question
« on: June 22, 2020, 08:23:00 AM »
Hi Folks,

I just bought a 5W module with an outboard controller (see attached) to upgrade my cutter.  It needs a 5v TTL signal in. 
I've been away from my laser setup for awhile, and seem to have forgotten almost everything I learned about configuring the hardware, so I'm back at the bottom of the learning curve again.  I have a Mana 5.2 board, running a 3-axis setup with a 2.5W non-TTL module.  The laser is currently connected to the motor output, and PWM seems to be working to control the intensity.

I've been reading through the threads here, and I think I have a handle on what I need to do, but before going ahead and letting the magic smoke out, I thought I'd check and get some confirmation.

So as I understand it from reading the thread here, I'm going to:
i) power the laser with an independent power supply into the 12v in on the board.
ii) connect the Analog - input to the Servo ground on the Mana
iii) connect the Analog + to the Servo PWM on the Mana.
iv) set the selector on the board to TTL.
v) cross fingers and hope!

Sound about right? TIA for your advice!

I keep checking back, my laser is churning away with BCL with minimal issues, but I haven't done anything too interesting to report on... short of ordering a 15W laser that Canada Customs refused and sent back... and then I had to file a claim with EBay. 

I'm in the "no-news-is-good-news" group. ;)

Mine's likely on the same boat... delivery between August and October.  I thought I'd take a chance on it since it was cheap... I know, you get what you pay for.  But for the price of the domestic high-powered LEDs, I can go to the local professional with the 120W Trotec and get the work I need done.  Otherwise my 2.5W still churns out the bulk of what I need to do reliably.  Slowly, but reliably. :)

Yes, inquiring minds want to know!  What can the 15W do that our 2.5W units can't?  Especially interested in what it can cut, and how quickly.

Is this the sort of grille you're talking about?

I've thought about that, or the lattice for fluorescent lights.  I've been using expanded steel, and I find the contact patch is too large, and I'm not getting clean cuts.

Z Axis / Re: Banggood Eleks Z Axis Kit - any issues?
« on: April 11, 2018, 09:59:25 AM »
For anyone that has this z-axis, how high above the x-axis rail does it project?  I've mounted my cutter on a drawer under a tabletop, but didn't think about needing extra vertical clearance for a z-axis... now I'm thinking I need a z-axis....  ::)

I think it's cool, but I agree with Zax, there's potential for some serious harm there!
Where's the light path?  I'm not familiar with how the CO2 laser systems work, I realize that instead of moving the laser itself, you're re-directing the beam and eventually focussing it on the workpiece.  How are you tracking the moving cutting head?

Thanks Ralph, I was pretty sure there wasn't an option there.
I've done some engraving, so I know the drill.  :D

Thanks Ralph,
I'm not sure where the option is to fill text.  I'm using 3.1h, and whether I start a new drawing, or add text to an existing one, I get this dialog when I select either "Edit Text" or "Text Settings".

BenCutLaser / Filled text with BCL? (CLOSED)
« on: March 24, 2018, 02:21:56 PM »
Is there a simple way to do a filled-text etch with BCL?  99% of my use is cutting, for which BCL is great, but I've been asked to do a couple of signs. 
I've used the add text to put in a few part numbers and things, but it only does outline (unless I'm missing something?).
Should I just create an image of the text I want to burn, and then treat it as a B&W or grayscale engraving?

Cutting / Air Assists Compared?
« on: March 20, 2018, 08:28:38 AM »
Hi All,
I have a Banggood 2.5W with Pawpawpaw's air assist, and it's working OK.  I've been doing a lot of cutting, and I'm wondering if anyone has done a comparison between the low-pressure high-volume approach that Pawpawpaw's has with the high-pressure/low-volume that you would get with a directed compressed air stream.  I've been reading through the posts, and it seems folks have gone with one method or the other, but I haven't seen anyone who's tried both and settled on a winner.

Is a compressed air setup going to produce enough of a difference/improvement in cutting ability for me to justify investing in a newer air assist rig?

Ah!  (see other thread).  Thanks for making that clear!  I was looking for the grab handle like some of the other windows.

And now I can see the scroll bar!  Yay!  Thanks again!

Ahhhh!  Got it!  Now it works!
