Expresscard parallel adapter was created by yongra
I have a Dell Latitute Notebook with Startech EC1S1P55254 Expresscard parallel adapter.
Does anyone know if this card is compatible with LinuxCNC Ubuntu?
At the moment, I have Unimat ML CNC and LinuxCNC does not control it at all. Also, the notebook will freeze constantly when I launch the axis program.
Thank you,

Hi
A laptop is inherently unsuited for running Linuxcnc, the fact that it freezes just opening Axis probably tells you all you need to know.
My advice, buy a cheap second hand desktop from the list of computers that work and use that, any time or money you spend on the Dell is liable to be wasted.

Thanks for the suggestion. The problem is that this will be placed in a mobile workshop in a Sprinter van with limited space and power source. That is why it needs to run on a laptop. This laptop is new and running with intel Core i5 with 4 gig of RAM. It will only be used with LinuxCNC. I did the latency test and it is not bad according to your manual.
Maybe it is the driver for the expresscard adapter?
Any other suggestion?
I am also getting this error when I first launch the program.

This indicates that the CPU has excessive latency for your current basethread or servo thread period
This is pretty much expected of laptops which often have power management hardware/firmware that cannot be disabled
This is why using laptops for linuxcnc usually a bad idea
One thing to try is to lower your basethread rate to say 1/2 its current rate (that is double the basethread period)
and see if the problems go away...

That sounds like a fun project, can you tell us more?
There are some Atom Mini-ITX motherboards that will run directly from 12-14V car power, and some of the PicoPSUs are specifically for powering motherboards in cars.
I have a DN2800 which runs on 12V (though that has interesting graphics quirks, easy enough to fix, but on a fresh install you have to fix them "blind" as the graphics aren't working, so I probably can't recommend that one.
This might be a good start: www.mini-box.com/Car-PC-Automotive-Computing-Solutions

This is a project that my college is running to show STEAM education in k-12 school. STEAM is for Science, Technology, Engineering, Arts, and Mathematics. The van is designed to go to various schools in NYS to show the STEAM initiative. It will have not just CNC, but other technologies like Laser Cutter, Robotics, and other STEAM related activities. So, the space is quite limited for a desktop and AC power. This mini-box PC seems to be a good solution.
I checked out the Mini-box.com site and I see one that has parallel port built in.
VoomPC-2 Jetway Dual Core Atom 1.86 GHz, 2x Ethernet, M2-HV, Jetway JNC9MGL-525
www.mini-box.com/CarPC-VoomPC2-Jetway-JN...5?sc=8&category=1543
Has anyone used this type of PC with LinuxCNC? I do not mind spending few hundred dollars to buy it. But I want to make sure it will work.
Thanks,

Which file or where do I make the change? Is it the .hal file like standard_pinout.hal?
Thanks,

It can be in the hal or ini file but if you used stepconf to make your configuration
its probably in my-mill.ini (unless you changed the name):
[EMCMOT]
EMCMOT = motmod
COMM_TIMEOUT = 1.0
COMM_WAIT = 0.010
BASE_PERIOD = 100000 <<<<<<<<<<<<<<<<<<<<<< here
SERVO_PERIOD = 1000000

D525 boards have done very well in the past, in fact the Intel D525MW was the board of choice until it became obsolete.
The only Jetway boards in the latency test page ( wiki.linuxcnc.org/cgi-bin/wiki.pl?Latency-Test ) show good results, so it seems that Jetway are not in the habit of messing up the latency.
Google can't find any latency test figures for the board, so it looks like a bit of a gamble, but not a terribly risky one.
You could always try phoning them and see if they will send you one on the understanding you can return it if the latency is bad.
