Anyone use the modbus serial card with EMC2? It has 4 bit analog input that
could
tell me my arc voltage... Also the control pendant they sell could be used with
the
modbus card... Any drawbacks to using this?
Thanks
John

If you you just need one channel of ADC, my DAC setup:

could be modified to run an ADC like the LTC1286:

It would take up two parallel port outputs
A while back, I tried printing an encoder with my CAD program. I didn't
get very good results. My laser printer's resolution, which is great for
printing documents, was lousy for encoders. What resolution and how
small a disk is possible with your method? Although, I suppose for a
spindle, a larger

Gentlemen,
Here I'm again. You will remember my previous mails related to stepconf and the
configuration dificulties I was suffering to make my EMC runing properly on my
Dell laptop.
Now, fortunately I have resolved the problem and I would like to share with you
my experiences just in case they

Thanks Alex!

I would feel confident printing 256 lines on a 2 inch diameter encoder,
with my 600 dpi HP laserjet 1018, but I haven't tried it out with a sensor
yet. At 512 lines, the spacing between lines starts to look uneven.
A 7 inch disc with 1024 lines looks pretty good.

Thanks for the reply. Are you suggesting that I do something like you did but

can
handle analog 0-5v inputs from a joystick. Perhaps something that would scale
the
0-220vac to 0-5vdc that I could somehow u
If anyone wants to etch a disc I can probably find an 30 mL or so of
KPR.
For best resolution make a 4X image and then photoreduce 4X on to
film and use that to expose the
KPR. It makes beautiful circuit boards that way.

Yes. Both the DAC and ADC move the data in the same way, by clocking in
or out one bit at a ti

Hi,
Just a quick not before I head bush for the Christmas camping trip.
For additional I/O via Modbus have a look at the ModIO. It has discrete inputs
and outputs, analog inputs, a 20x4 character LCD interface, plus a few other
interfaces.

Good try. KPR is a photoresist made by Kodak. It is good enough to do
wafers.
It needs reasonably energetic UV to polymerize and then toluene to
dissolve off the non-polymerized part for etching.

KPR is abominable to work with. I have DuPont Riston dry film
photoresist. I have laminated it onto .005" and .003" brass
shim stock with my dry film laminator machine. It has heated

Kodak Photo Resist, a Xylene-based organic photo resist that is
hardened by exposure to UV light. It is very "old school" and
not only requires nasty chemicals, but is quite fragile.
