I have :
USB Easylase, Mamba black, DT-40 galvo.
And i did do:
Solder the wire from the galvo to the DAC
X and Y signal from the X+ and Y+ pin ..
And the ground - signal from Gavlo into the GND on the USB board...
And the blanking BLACK-wire from laser into the GND on the USB dac.
Then i connected the yellow to GREEN colour output + signal output from DAC, ( i did also try the blanking output, and i did also try with a resistor and not)
The problem:
I dont have blanking (the laser dont come ON at all....
And one galvo is only moving a tiny bith (like half the way) !?!
Symptons:
When i make a line UP at the mamba, the laser goes UP..
When I make a line horisontal, the laser only moves a TINY bit !
But when I switch the X and Y wire from dac, it`s the oposite (that confirms that the galvo is OK)
I have tryed to use this USB with popelscan, but nothing happens!!
So i dont know what to do ?
I understand that there is a + and a - I can try to use from the DAC, but my galvo have ONE GND togheter...
And i`m going to try the + and - signal from DAC to blanking (and not + and GND)
any info ?
this is first time i try a USB dac... so i`m totally blank on this..
