And your point is ?

Altium Designer for 20 English pounds sounds reasonable. Are you sure that
was not one of their earlier Beta versions? How did it work? ORCAD is much
more expensive.

Sounds like you are responding to a post by Marra. Who supposedly wrote
his own full-featured layout package and now sells it for 20 pounds on EBAY.
Marra responds to every enquiry about PCB software with his lies about
buying his own software, on EBAY for 20 pounds. Go ahead and buy it from a
guy that lied to you in the first place. Why not? Not only is he a troll, a
liar, but he also obviously doesn't think that his program is really worth
more than 20 pounds.

Even drafting and PCB standards cost more than $40. ORCAD Capture, Layout
and autorouter could run several thousand dollars.

An interesting read!.

The Roland should respond to something like "VS 1,1" added to the top of a
HPGL print file, (ie Velocity select #1, for pen #1). Is this not an
option?.

Thanks for reading.

It does respond to VS commands as low as 2 and that definitely helps in
slowing it down, but it's not quite slow enough.
I have to do multipasses on some materials to cut them.
Also I'm pushing the limits on the whole current vs torque issue.
As I slow down it down, it has a bit of a problem with torque or
overlapped stepper motor pulses (I haven't investigated yet) and so has
repeatability issues.
But I'm just a hobbyist here and it's a good start.
I may end up ditching the motors and electronics and starting off with
something better, but it was more along the whole "can it be done?"
thing than trying to end up with a piece of reliable production
machinery.

Kevin

Looks suspiciously like the stepper driver motors are being powered down
(too early) to a 'holding torque only' condition about 1/2ms after an X or Y
step pulse has ended (IC134).
A thought only, but maybe linking out R147 and R160 could keep motor power
applied all the time, thus can deal with the slower step rates at full
torque.
Personally, I'd be inclined to drive the motors directly from 2 external
stepper drives fed directly from that printer port. You could then set the
motor current at will. Seems lots of CNC progs available that will translate
HPGL (or G code) to printer steps under your direct control.
Or even, do the translate prog yourself with aBreshenam line and (maybe)
circle draw routine. Most CAD progs out there just seem to generate 'move
to' and 'line to' commands and ignore 99% of the available HPGL or G code
possibilities.
Having said that, I haven't a clue about Macs! and these things simply may
not be possible

Keep in mind that the Rolands have steppers with around 38 ohms on
their coils.
One of the stock motors in the engraver is about 3 ohms per coil.
A huge load.
So I'd probably be apt to replace the motors or add a driver stage and
treat the old drivers as pre-drivers, but the whole PWM/chopper thing
is the first to get looked at.
[...]

Maybe it is the other way round, in that the Roland chopper is fixing the
current at say a constant 200ma feeding it's design 38ohms load, hence a
motor power of 1.5W but that same 200ma with a Chinese 3ohms only gives
120mW motor power!. The PSU voltage should have virtually no effect.
Anyway, I hope one day to have my own death ray.
Best of luck with the project (and please do a video of it cutting or
marking some plastic .

I've just released a wxWidgets and OpenGL application
for designing Printed Circuit Boards. It's quite unusual in that
it lets you create flexible tracks which can move and bend freely,
while always maintaining your design rules.

It certainly looks like an interesting experiment in both user interface
and PCB style. Couldn't get it to do anything sadly, it just stuck in
dragging a box and wouldn't respond to any icons. There doesn't seem to
be anything in the libraries yet, and no example PCBs that I could find.

This sounds like "Rubberbanding to the nth power"

or "Rubberbanding on steroids"
or "Mensa Rubberbanding".
Any quibbles WRT my descriptions?

Also, unlike most CAD packages, there are no banks of icons, and no
File, Edit .. Help menu. All functions are accessed through the
multi-directional expanding mouse menu.

I would be very grateful if this application can be featured in the
wxWidgets showcase.

More info about the project can be seen here:

Sounds interesting from a UI perspective. What about the back-end? Is it
compatible with other EDA tools? Can I load the files into gEDA?

Ales Hvezda, the author of gnetlist is kindly offering to write a
gnetlist backend to export the .XML format netlist files which Liquid
PCB uses.
Meanwhile, another kind soul is trying to compile Liquid PCB for
Linux. I'll make the Makefiles and instructions available as soon as
this happens.

I hope to have Liquid PCB working with gEDA as soon as possible. Any
contributions gratefully welcome.

I think that their general policy is to keep the products as distinct
as possible, with Easy-PC intended for the hobbyist and educational
market and Pulsonix serving the needs of the professional PCB
designer.

The standard gameplan in the U.S. then, would be to be handing out Easy-PC to
universities for free or almost free to get the students "hooked," making sure
they're aware that the "professional" version of the software is Pulsonix so
that's what they should be purchasing when they begin working professionally
and have some capital to blow.

Pulsonix has *lots* of stuff that will
probably never be in Easy-PC like paired-track routing and microwave
track mitering.

Yeah, but if you're doing serious microwave work you're going to be using ADS,
Microwave Office, etc. anyway and then importing the Gerber output back into
Pulsonix as one complete "stamp."

---Joe

It's still very useful for a lot of users that don't need to get to
grips with those sort of packages, and are just designing a simple
circuit.

Some of these high flying packages are great and complete but when it
comes to a quick and dirty small PCB a cheaper package does the job
much quicker.
Some people that bought my software came from other vendors and
complained about packages being hard to understand and to get started
took a long time.

"http://www.pulsonix.com
Support is excellent."

It's certainly well above average, but at least for *me* to call it excellent
they'd have to fix all their stupid little bugs, such as getting pin name
labels to end up in the right positions when you use next gate/previous gate,
that they've known about for something like a year now (although it's clear
someone there tried to fix it in the latest release, but unfortunately ended
up making it worse!).

I have pretty high standards though... to me something like ORCAD (which has
tons of bugs that have been around for many years, nearly non-existant
"support," and lacks features that make something like Pulsonix more
productive) is clearly in the "sucks hard" category whereas plenty of people
would label it as "OK."

Hi,

I've got a problem with DXP.

When viewing the gerbers, it appears that we have some components
duplicated outside of the board area, but only on certain layers -
specifically the solder and paste layers, but not on the normal top layer.

I've tried the old trick of selecting outside area and trying to delete
them but they won't show up at all in Protel. Using the inspector list, I
can't see them either and definately can't delete them.

Any ideas?

Thanks,

James

Typical..... how about turning all layers on and retrying? I've found
library errors that cause similar problems in the old 'Client' version and
the culprit was in an odd ball layer.
