T2 Engraving / Re: overscan/dynamic laser power/dark edges
« on: October 24, 2019, 10:35:11 PM »
Ok Zax, here's the trials:

1 - Bi-Directional Scanning On, Overscan On, Dynamic Laser Power On
2 - Bi-Directional Scanning On, Overscan Off, Dynamic Laser Power On
3 - Bi-Directional Scanning Off, Overscan Off, Dynamic Laser Power On
4 - Bi-Directional Scanning On, Overscan On, Dynamic Laser Power Off
5 - Bi-Directional Scanning On, Overscan Off, Dynamic Laser Power Off
6 - Bi-Directional Scanning Off, Overscan Off, Dynamic Laser Power Off

It appears you can't do overscan with bi-directional off.

The dynamic power is obviously a big help.  Bi-directional and overscan didn't seem to make much difference.

I'll give it a try tonight and see how it goes.  Thanks!

T2 Engraving / overscan/dynamic laser power/dark edges
« on: October 23, 2019, 09:56:34 PM »
Zax,

I'm getting dark edges on one of my machines, not the other.  It's running an endurance 10w.  Exact same settings as my other eleks 2.5w engraver (I can use the same gcode, same instance of T2 just switch com ports). 

I've got overscan enabled, dynamic laser power enabled, yet still get dark edges on that machine.  Is there some kind of delay or something or additional overscan, I'm thinking the endurance isn't turning on/off as quick as the eleks on the change of direction?  I know it can change laser power, I can burn at various power rates and get different light/dark results.

The endurance one with the problem is running on a eleks 5.2 3axis controller, the other on a regular eleksmaker 2axis controller, both running 1.1e.

Thanks!

Nottingham - You know that you can generate both gcode files and paste one at the beginning/end of the other, then load it and it will do both without stopping in the middle?  It will go back to home in between, but it gets you out of having to load the second file.

Trouble Shooting / Re: Endurance Laser 10W Plus
« on: April 22, 2019, 08:43:59 AM »
I bought mine as a kit and assembled myself, with lots of help from George.  I don't know if the ones he ships pre-assembled are all tuned for proper voltage/current.  Mine is tuned where under load (laser full power) it's running at 4.5v/4a.  Sounds like yours is WAY underpowered right now.  See the instructables link I posted before to adjust the DC-DC stepdown converter, hopefully it will get you closer to where you need to be.

I've got one as well, built it from kit.

You may be able to check your wiring from my diagrams in the instructable I wrote here:
https://www.instructables.com/id/Assembling-an-Endurance-10w-Laser-Kit/

I've found that even at a power level of 5 it will mark on alder wood.  I use 1, and the manual controls in T2.

I just got a couple of the eleksmaker TTL to PWM modules in, haven't had time to wire one up to the 10w yet.

General Discussion / Re: Spindle on A3?

Update for future lookers -

Talked with eleksmaker directly, long story short - it is what it is, not enough power for cutting.  I was finally able to cut MDF with the eleksmaker spindle, but it was at speeds around 50mm/min and <1mm depth of cut with a 1/8" spiral upcut bit.  Far too slow to be practical.  The spindle is definitely made to do very shallow engaving with a pointed bit, not cutting.

It's this setup, a 12v spindle:

But like almost all of the eleksmaker stuff, came with no documentation.  I can't find any info on the wiki about the spindle, the top has a barrel jack and a red 2 pin connector.  I currently have the barrel jack connected to the motor port on the controller.

Ok, wondering if any of you have any experience with the eleksmaker spindle.  I picked up an eleksmaker z-axis, 3 axis controller and spindle.  Finally got it all setup and running yesterday.  Everything functions as expected, all three axis move as they should.  Only problem I'm running into is that it seems the spindle is so underpowered it's nearly useless.  I put in a 3mm spiral downcut bit in it, and it would bog down enough to stop the spindle doing a line at slow speed (I think around 500 in T2) less than 1mm deep into mdf.

Just a question, as I'm looking at rotary devices now.  It looks like the three jaws on your chuck are not connected in any way, so how do you guarantee the object is perfectly centered in the chuck?

T2 Engraving / Re: extra line ?

I don't know what laser you have, but with my 2.5w I find the best results at 1700@255.  Slower feed rates will tend to give more of a yellow/goldish color, 1700 for me gives a nice off-white.

I seal with a coat of spray deft or poly.  You can use any of the finishes, some of my customers like the matte, others the glossy.

I experienced issues last night as well, probably around midnight pacific time.  Constantly got the 'the site is taking too long to respond' type of error.  It's working this morning.

General Discussion / Spindle on A3?

Don't know which forum this should go in, so admins feel free to move if needed.

I've accumulated a stash of parts, started with a standard A3 and put longer rails on it, then picked up several more A3's second hand.  With the extra frames & electronics, I got to wondering...  Have any of you built a CNC on one of the a3 frames?  I believe with the 3 axis mana board, a Z axis, and T2 to send the grbl, it *should* work theoretically.  Are the eleksmaker steppers strong enough?  Are the 2020/2040 rails strong enough to not flex?  What kind of spindle can you run on one of these?

If anybody has gone down this road I'd love to hear/see what you've done.

Not an elegant solution, but if this is something you're going to save the gcode to run multiple times it works, essentially doing the tiling in image editor.  I do a lot of 100mm square coasters.  I'll create the 100mm square image, then create a new 400mm square blank image, then one at a time paste the original 100mm image in each corner and save.  Open up T2 and generate the gcode for each with starting point at a corner.  Then open a text editor and paste in the contents of each of the 4 .nc files in the order you want them to burn.  You'll still have the issue of the laser returning to 'home' between each of the 4, but it's just a few seconds.

It takes some time initially, but if it's going to be a repeated thing it will save a bit of burn time.
