General Questions / Re: 2500mw laser/mana se board hookup
« on: Today at 10:50:17 AM »
No, you need the board, that's the laser driver circuit.

The laser connects to the end sockets as shown in the pictures, then you connect the Mana SE board and power supply to the other connectors.

One is labelled TTL/GND, so the TTL is the S-pin on the Mana SE laser connector and connect the GND with the power supply GND (-) input and the + power supply to the IN V connector.

Oh no, the pressure...  :D

T2 Engraving / Re: Bidirectional offset
« on: Today at 08:28:43 AM »
Actually it is in the manual, but support is never a waste of my time.

Image Options
o   Bi-Directional Scanning (default)
o       Horizontal scan mode follows a serpentine pattern
o       Disabling will scan left to right only

Photo Mode
o       Uses a pixel shifting algorithm (similar to anti-aliasing) to blend the grey levels for a more natural look.
o       Produces a "softer" image (not recommended for clip art)
o       This algorithm will be used if a suitable image is detected and does not normally need to be manually selected

Spare Parts Sources / Re: A4988 stepper driver
« on: Today at 07:58:42 AM »
I must have missed that, it looked like the same pinout. Why the heck would they change it, so they're not drop in compatible. I wish they would have dip switches on the driver instead of relying on the board, which as we know doesn't always have a way to change it. You could still override with the board if you set the dip switches off (no microstepping), seems that would be the best of both worlds.

Edit: It looks like they are pin compatible so you should get the same 1/16th microstepping if using an Eleks board.

You will lose top speed though as Grbl is limited on the step pulse frequency. 1/16th already has plenty of resolution and as you increase the microsteps you lose torque (not that the lasers need much).

Do you have Photo Mode enabled?

That should not be set, it will be automatically selected by my algorithm when needed. It is designed to eliminate moire patterns in an image caused by scaling. It "pixel shifts" by one unit to break up the patterns and soften the appearance of the image, this is a common visual effect used in TV/Movies to prevent vertical lines.

Obviously for solid text or black/white that would not apply.

The driver board has a TTL input, so you can use the laser connector on Mana SE board.

Connect + / - from Mana SE to the laser driver power and S to the laser TTL input.

T2 Engraving / Re: Hatching - how do you guys do this?
« on: April 28, 2017, 03:34:59 PM »
If you want to use different hatch fills, and/or leave some un-filled then Corel or Inkscape would be the best bet. I like Corel as it will automatically convert colors to hatch fills at PLT export. Of course it isn't free, so if you don't have it Inkscape wins and does a great job too.

Agreed, it does look better with the background. If you reduce the burn on the face it may look better.

I think that turned out awesome, lots of detail and shading.

You're on the right track with the process, cleaning up the image and removing background really helps as does making sure you have good contrast.

The 2.3W is TTL, get that and use the 10% coupon they have currently for all EleksMaker products. It stacks on any other discounts but not points.

Nice job!

What program did you use to create the .nc?

T2 Engraving / Re: Error on engraving
« on: April 27, 2017, 04:42:21 PM »
I checked my main development PC and it has similar settings to what you had (before changing them) so I don't think that's the fix, but still worth testing.

What's odd is sometimes you get almost all the way through a job, other times it errors early.

If you are using the latest version of T2Laser there's a menu option to install the most recent CH340 driver, maybe try that if you still have problems.

Looks great, and slightly 70's  ;)

I would add a fan and make sure it's got some air flow.

That would work without any changes, just use the software normally.

Very simple for rolling pins but may not work on much else.
