   Ive checked and Im pretty sure its a limitation based on hardware. While in config one can do less than 1khz, Auggie updates its registers at 1Khz, and usually that means a register reset in the PWM chip at 1Khz, if I dont miss my guess Mat will tell me it cant go lower unless Auggie goes slower..

Hello everyone and happy new year  ;), i finish al my work and now i have some time o play with Auggie . Now i figure out is a very nice software based on open source library . i take a look in almost all scripts. To understand better , any modification in "scripts" folder , will directly reflect to Auggie right ?
About what @Tweakie says , i has the same problem years ago with same " hardware limitation on PWM " so i write a small function without be based on timer tick , just to trigger the function . Unfortunately i dont know how to do that in Auggie , i need to study first how that work , the code is written in pure C and very simple to understand.Also the code permit to adjust the duty cycle period if that matter.

Can be good way to understand how that work in Auggie .
Happy new year again  :) :) :)

Awesome! Great job.

Good luck, yell if you get into trouble, sounds like your on it though.

Tweakie,

Thank you for the advice.

I've never really liked the Xylotec board so i just ordered up the 57CNC board and 3 stepper drivers along with some cables.  Ships tomorrow from Slovenia. 

Once I get the machine running on the Pokeys board and Auggie, I'm sure I'll be back here for guidance on the actual image prep to see if I can get the results you have shown in this thread.

Absolutely amazing.  I'd be ecstatic if I could get ANY of those 3 images burned.

Hi Mark,

You can burn those images.

You just need the 57CNC (latest version) - that has a parallel port output which will feed directly into your xylotex controller.

Absolutely amazing.  I'd be ecstatic if I could get ANY of those 3 images burned. 

I agree, #3 offers the smoothness look of the three, good job Tweakie

number #3 I think.. :)

  The math on that is pretty clear for photo engraving, the CNC57 controls the laser every 1ms,
so if I want 800x600 on a photo, Id need to take 800ms to cross the field at a minimum. I could do that fast on my conventional almost, but the saving in galvo should come from having
infinite acceleration and deceleration. (Or thats what Im hoping. :) )

  And then there is the material burn time, but I suspect with 50 watts Ill be able to move
as fast as a step/dir galvo can.. with the above limitation.
