Possible. The Pro file is from yesterday, and the Basic file is from today.
I don’t recall ever not having the long space at the beginning of the pulse files I looked at, but I could be wrong. Do you still have any of the earlier files?
I haven’t found any other settings for the HV power supply other than the watch dog, enable, and pwm. The pinout accounting is pretty thorough at this point.
That would explain the “better optics” statement.
Yes I still have all the files I looked at. I checked a random one to make sure. Starts with Z steps and then XY motion. The Z steps can take some time if the focus is high as they step it very slowly.
Discourse doesn’t like conversations with only two people!
Well, it better get used to it on this site. 
This is the PWM output for FULL power on the OpenGlow board, on my Basic:
This is the result of writing the value 0x66 directly to the SOM’s PWM compare register (controls duty cycle) by the SDMA script.
I have no doubt that some Glowforge staff are lurking. (Hi guys! We do really like some aspects of the product, honest! Please keep adding new features!)
They are the same tube.
