The motor move opposite way in manual control (not a real problem)

In Laserweb if i set an image 10cmx10cm (a circle) the engraved output is a little smaller.

The latest strange thing is that with T2Laser (paid version) 1000 laser power setting apparently pilot more power then 100% in laserweb (the generated light is stronger)
100 percent is 100 percent. What changes is what your laser determines is full power it sounds like your laser is set at full power as 1000. By default t2 is 255. So since your firmware is using 1000 you are telling the laser to use 1/4 or 25% power in t2 when you input 255. If you restore defaults in t2 255 will be just as powerful as any number above that.  Because 100% is 100%

Before I do anything, what firmware should I be using?
1.1e default

ok now that i see it.  All that stuff about 5v doesnt apply to you.  You need to know one thing.  when you go into the laser software and turn on the laser do you get 12v between the two posts in the red connector?  If so you have a bad laser.

If you do not get 12v with the laser turned on in the software then your mosfet is most likely blown.  That will require you to solder on a new one or replace the board. 

We know it is not your nano because you got the 5 v on the s pin.  (not that you will use that pin but it is indicative of your nano being fine)  So now we know its your mosfet or your laser.

you might be better off just showing us a picture of your set up.  I suspect you have it wired wrong.  To post pictures here they need to be fairly small to save server space so if you take them with your phone you will need to resize them.

Fan pins. But they get the same voltage.

There are no fan pins on a mana Se.  There are 3 laser pins, 4 servo pins, 2 motor pins, and 4 serial pins.  are you referring to the motor pins which have a red connector?

Other Software / Lightburn

There is a new software which someone is trying out on the facebook eleksmaker group. 

https://lightburnsoftware.com/

I have downloaded the full feature 30 day trial.  It does not come with firmware so you either need to know how to modify your firmware yourself or use zax's T2 firmware before going to laserburn.  It does not do rotary.  It is $30 for grbl license (which is for 2 pcs and any number of lasers) or $80 if you need to control co2 laser.

It does use home switches very well.  I definitely like the fit/finish and feel of the software.  It works well with dxf and svg files.  It can also easily adjust power and speed of specific lines.  All in all I would say it appears to be a nice software but for me cant replace t2 due to the lack of grbl firmware support and lack of rotary support.

If it's a two wire laser you should get 12v from the two wires with it turned on in the software. If there is something wrong with your firmware it will also show during this testing. Because the electrical symptoms will lead you to the issue

Also... How did you wire your laser. It should be to the 2 pin motor connection.

"If you are getting this then there is something wrong with your board or wiring.  If you are getting this then there is something wrong with  your laser"
 
I'm assuming you mean: 'If you are not getting this, there's something wrong with your board or wiring'? and 'If you ARE getting this, then it's something wrong with your laser'? Also it's just a two pin laser. So I'm assuming it's on the opposite signal/boolean value? of what it needs to be. I'll definitely check the voltages but do you think this could be a firmware issue and I've missed the correct hex or didn't install it properly? I'll definitely wire the two pin if I need to to double a pin for one wire as it's described in the other thread.

I'll get out the multimeter.

step one.  Break out your multi meter.

Step 2: unplug your laser and check what voltages you are getting at the laser on the 3 wires.  you should get 12v on the +,  ground on the -, and 0v on the S pin.  Then turn on the laser in the software.  You should now get 5v on the S pin.  If you are getting this then there is something wrong with your board or wiring.  If you are getting this then there is something wrong with  your laser

Step 3 if you did not get the correct voltages on the last step go back to the board and see if you are getting the correct voltages on the board.  If you are then its your wiring.  If you are not, it is a board problem.

Make sense?

you can just turn the laser power to 1 then click engrave frame (power on)
This will not affect your gcode and your engraving will still be at whatever power you had set.

time to break out the multimeter.  It could be a number of things.  Start at the laser and work your way back.  Are you getting 12v on the + pin.  Are you getting 12v from the power supply.  Where are you not getting power.  It could be the board, power supply, or laser.

I couldnt offer an opinion on that.  I have a 1.6 watt laser and 2 2.5 watt lasers.  Personally I wouldnt want one that does not have an adjustable focus.  If you were to get an adjustable z axis then it might work. but I wouldnt want to have to deal with moving my piece up and down all the time.

I would not trust anyone who sells you a cheap diode laser made in china.... that being said... I have bought from eleksmaker.com banggood.com gearbest.com and had no issues.  There are some american companies but expect to pay twice as much for the same wattage of laser.

T2 Engraving / Re: Burn Speed
« on: January 13, 2018, 01:37:22 PM »
yes on both accounts.   The first is called bidirectional scanning. Its under settings-->image options

The second is set in the feed rate options.  Give the rapid feed rate a speed of 3000mm/min and your engraving feedrate something lower and appropriate for your materiel.  Then in the laser control screen click on Settings--> Advanced --->jog rapid feed
