Hello EMC users,
I have difficulty when adding additional parallel ports (other than the
parallel port on mother board) and configuring them as input. When I monitor
the pins 2 to 9 they are
always off, but the pins 10 or 11 are on. I do not have this problem when I
configure the parallel port

I believe EPP is the magic acronym.
EPP mode is only for communication with external I/O hardware, like Mesa cards.
Farzin, You should check, if that add-in card supports data input on pins 2-9.
AFAIK not all do.

;Could you tell what I need to do to make pins 2 to 9 act correctly on the
additional parports too.
As suggested, it is the type of card
that matters.
I found that newer NetMOS chipped cards work, 9865 chip or newer springs to
mind .
Google the forum it is all fully discussed there.

Well - I gave up trying to figure it out and scaled the velocity from the
encoder counter by 16.66 and now it read correctly. So - boring at 300RPM
and .001 IPR gives me .3IPM which seems right.
Awesome - now when I slow the spindle rpm - the IPM slows also. (taking the
same cut at .001

I just was greeted by an update request when I turned on the monitor, so 2

I remember that the developers at one point changed the way g64px.xxx worked so
that it actually converted arcs to short line segments so the combining of line

I don't know if you're still trying to figure this out.
What was the encoder scale set to and how many pulses per rev does the
encoder put out. If you're using a quadrature encoder with 250
pulses/rev, the scale should be 16.67 = (250 pulses/rev) * (4
quadrature counts per pulse) / (60
Gene,
I don't have experience with the G540, I am using the Vampire series
which are a great set of drivers but they are not faultless!! But there
return and support on broken drivers are very good.
I did hear some good news from the UIM 2400xx series www.uirobot.com
I know a couple of guys
In general, the G540 has a good reputation.
Unlike Xylotex, Geckodrive will repair
their products, usually for free.
The speed and power of your motors will
improve noticably.
The G540 does have one design quirk. The
inputs are optocouplers driven from just
the power of the parallel port

Further testing would be helpful to see if it's only stepper systems or
that servo systems see the same slow downs.
The burning problem is because the spindle speed and feed are optimised
for cutting at 3200 mm/min as per cutter manufacturers spec. (It's an

I can't specifically comment on the 540, but I have used the G251 drives
that are part
of the 540 package, and they seem to be just as good as the earlier G201
drives.
It is pretty rare to let the smoke

I am pretty sure they have a 4A and a higher version of it, not
only 2amp at 40VDC
I never used them myself, but I here they where cheap and pretty reliable.
This guy didn't put them on his 34HS9802 (Nema 42), but in a box with some
additional cooling.
