Used your setting too. Only change  I did was set the speed to 80
Yeah 40 isn't necessary but I like to be sure. I don't want to have to redo it.

T2 Engraving / Re: Newbi - Aliexpree DIY laser incoming

Yes. It should work as it looks like a standard board.
Wow they finally started cloning the Mana see boards.

Where are those mugs located in a Walmart?
For 0.07 res, what DPI do you export at?
Does the electro etch really help?
Do you just use mr clean eraser and water?

I plan on testing again now that my file is fixed.
I use the Mr clean with a dash of water. Buy extras because the wife will try to steal some and clean pans with them.

Electro etching just seems to bring the shine back to the metal. It isn't necessary.

They are merchanised weird. I've found them in seasonal, home goods with other travel mugs, sporting goods with water bottles, and camping. At the Walmart nearest me they are usually back near camping.

For .07 I just use 254 dpi and import at .1. Then once it is imported, I change to .07. If you do it in that order, the size will stay right. If you import with it set at .07 it will change the size of the image.

@Sir Nottingham - Good to see you active again. Available everywhere might be a slight exaggeration. Technology comes slow to my corner of the world.
Don't tell me you don't have a Walmart!!! Lol but seriously Walmart is one of the cheaper places to get one. Also I am aware of the double negative in the first sentence.

Can you describe the materials used, work flow, and recipe? Is the glass pre-coated? I'm jealous!!!
These are powder coated stainless steel mugs. Available everywhere these days. The laser removes the powder coat. I use speed of 40mm/min and a resolution of .07 so there is a slight overlap. Also I use a rotary device. I clean up the engraving with a Mr clean eraser. Then electro etch.

I think this turned out ok
Looks pixelated. Did you use a low res image? The etch looks good. Dark color mugs look best. I did a light green mug and it didn't provide enough contrast. I like black mugs best

Trouble Shooting / Re: Grbl 1.1f broke my laseraxe engraver ?
« on: August 05, 2018, 12:59:56 PM »
Hello I have a problem with my laseraxe engraver. I wanted to use Laserweb4 instead of CNCC software, and I've read that I should flash the grbl 1.1f - and so I did. Now my engraver is indeed recognizable in Laserweb4 and T2Laser but my engraver is now working only in one axis and only in one direction. When want it to move in Y axis no matter which direction it always go to the right, and when I try to move it in X axis it only makes quiet humming noise and nothing happens. Laser is working though. I also later flashed 1.1e wth t2 laser but effect is the same. Is there anything I can do or my board is bricked ?

I am very new to all this, I have this laser only for few days.

The engraver is 100x100cm 10W engraver I bought on aliexpress. The is Laseraxe.cncc.mini logo on the board, and the controller is Atmega 328p I think. There is very little potentiometer underneath the arduino controller.
Laseraxe uses special firmware. There is a firmware that should work in t2. It is labeled as laseraxe

Trouble Shooting / Re: Y axis Steps REALLY short
« on: August 04, 2018, 02:23:28 PM »
Hey all,
I am having an issue with my A3 pro. When i go to engrave a 10mm square, my x axis is perfect buy my Y axis only goes about 2mm.

I am using T2 laser. I haven't done anything outrageous to ruin something. It was working 2 days ago just fine.

Here is what I have done so far:
- taken belts off to see if there is extra resistance
- swapped out motor driver from my other control board to see if it was that (same reaction)
- reset T2 preferences to default
- reflashed firmware.
- checked firmware steps/mm (all good)
- tried with another power supply that is known to be good (taken from my other laser that I was using today)

Any help is greatly appreciated
Try different wires?

sooo what I have found is that the actual time is never higher but can be significantly lower than the estimated time.  If I run the entire job with one speed (rapid move, engrave and cut) , the estimate is accurate. 

If I use an increased rapid move speed for moves when the laser is off, it can over estimate the time in which it will take to finish.  Sometimes overshooting by hours on big projects.  I have always just assumed it was due to the algorithm computing all the moves at the engraving speed and not cutting out the time for the high speed moves, but i guess the black magic on the acceleration and decel could be just compounding because its a long job.

T2 Engraving / Re: Trace/Auto trace
« on: April 24, 2018, 11:20:34 AM »
I am trying to make a decal and want to set up T2 to cut an outline of the .jpg.  When I use auto trace it picks up a variation in the color of the jpg and adds extra lines.....I just want to cut around it.  I couldn't get trace to work at all....not sure if I am doing it correctly.  Is it going to be possible to trace around the outside of this to just cut out the decal?
Trace is what you want. Click Trace then click the side of the line you want traced.

gotcha.  Thing to remember is the laser control panel setting are for manual operation.  They dont change your g code unless you select override power or override speed.  so make sure you go back out and regenerate you gcode when you want to make changes.

Here is a video I put together.  The first part is how to enhance a picture for laser engraving.  The last part addresses how to set up t2.  You can start at 5:24 if you just want to see the greyscale setup I use in T2

ok i think your terms all all mixed up.  If you are using the firmware in t2 then the max power is 255.  600 and 1000 would both be over 255 so they would just be converted to 255.  My guess is what you are calling power is actually speed.  speeds of 1000 or 600 would show a diffrence.  What you are calling resolution is actually our power.  Resolution default is .1  This means 10 lines per mm.  a resolution of 64 would be 1 line every 64 mm. 

So what I think you actually mean is

power 64-255
speed 1000
resolution .1

Having your terms right will help you interpret the setting other people are using.  I post all my settings in the project posts that I do so I can use them again the next time.
