Displaced time.

I always install in C:\Gearotic to avoid file access problems

Will it work as a Portable program? (Not using registry and saving settings in program directory)
I am a fan of portable programs - so easy to handle...

Hi Art:

I was suspecting Windows 10 as this was the new element...
Looking forward to next version.

Just installed Windows 10, Pokeys and latest Auggie 1.51. Copied changed panels, scripts and profiles from old installation.
Starting Auggie without Pokeys, I get the option to start simulation, and select yes. Next dialog says that "Missing Simpack.bin file.".
The file "Simpack.bin" is found in the ...

Thank you for explaining the inner workings of the power supply and CO 2 gas lasers. I sounds right to me!
High voltage in transformers can only be generated with an AC input or pulses, as we know it from switch mode power supplies.
The voltage and current on one side of the transformer is ...

Another benefit of this configuration is that I am not bound by the 20kHz requirement for current control. I could use a lower PWM frequency as the current is managed by a DC voltage from the potentiometer.

When browsing the net for cut/engraving settings I often see a recommended frequency - often ...

Art:
I plan to use the optical isolated input that the original Mosidraw board used and the analog potentiometer. The optical isolated input can be used without any modifications - using the analog input for PWM can result in over current if voltage gets to high and I have no electrical protection ...

Art:
Thank you for the explanation - that clear up a lot of things! :D

I have been reading a little more from power supply descriptions and it seem like I have mixed up the two ways the laser can be driven: Continuous and pulse driven mode.
From the Chinese descriptions it is hard to get head and ...

Art:

I my setup, the laser power slider and S word is controlling PWM #2. That is the way I configured it.
Replacing PWM #4 back with the potentiometer will engrave using the output on PWM #2.

I don't know that much about laser power supplies, but I was of the impression that the potentiometer ...

Art:

On the power supply there are three inputs: TTL (fire), On/off (Enable/Protection) and Current control (DAC/potentiometer).

I have attached a handmade sketch of my current wiring.

There should not be any conflicts between TTL controlling the laser and setting the current for the tube ...
