My adventures with Auggie.

Thanks, Ill check out why and fix it. I have changed it here to higher frequencies as a test, but hadnt gone any lower. Ill let you know
when its fixed.

  Can you check next time and see what the message says in the log. (Log is large button top right of screen.). Usually, on an M3 command youll get a message telling you what the new period was just set to be. If the Spindle library says .01 , it should give that in the message..

Thx

Hi Art,

Sorry to bother you with this, I am obviously doing something wrong but I have no idea what.
As far as I can tell the log is correct ? it reflects the Engine/Planner config.
I can set a period of 0.01 in the Engine/Planner and it stays set.
However, the measured PRF is 1kHz (as shown in the Pokeys config.).

The abnormality is that I can set and measure any PRF above 1kHz without issue I just can?t get below it.

  lol, never assume its you. With over 100,000 people using Mach3,
one can assume their screwing up is m3 doesnt do as expected,
but in Auggie, your a member of a very exclusive group, probably less
than 20 at any rate. This means any variety of small weird things
can occur.  The Pokeys actually has firmware code in it specifically
for Auggie, they've been great to add it for me, and it undoubtedly
could have a few bugs, or it may be my code.

  Ill run some tests in there and figure out why it wont go
less than 1Khz. Ive probably only tested down to 1Khz. In fact
now that I type this I see a correspondence here, I control
the pokeys at a 1Khz frequency, 1000 waypoints of motion
and control per second. This may explain why, in the context
of Auggie the limitation exists.  I dont KNOW this, but the
1Khz being a magic number tells me there may be a connection.

  Ill check it out and ask my firmware contact why that may be so
if it is a limitation on the Pokeys end.It may very well be that in
the very special "Auggie" mode in which I operate the Pokeys, that 1Khz
is the slowest  it can go. The log numbers being correct also
lead me to that conclusion.. but Ill check it out to be sure.

  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..

But Ill let you know when I hear.

Thanks Art.

That would be a shame because it would rule out 1 bit images that have not been dithered being re-produced with an electromagnet.

In the meantime another 8 bit image laser produced.

That works really well. )


  Ive asked Mat and he doesnt see any reason why it may be limited, so
Ill debug it next run of Auggie to make sure my protocol is proper and if so
ask it be verified.

Ill let you know the result.

Thx

I will keep my fingers crossed

I was not sure if this could be reproduced using Auggie but it is one of the finest optical illusions of all time. Perhaps hard to see the letters but the two squares marked A & B are exactly the same shade of grey.

Good question, Ill have to think about that one .. Id think
linearity would be very important..
