Re: [Emc-users] Problem Connecting LCNC to G540 from PCIE Port

When you use the word beginner I'd say forget all the experimental stuff
and just get a desktop PC. I just purchased this setup and the latency
is really great, usually < 9000 with an occasional 13300.

After spending a day or two dicking around on two old computers, I bought
this system. It worked great!

Also got:

This gave me a complete system in an old box. Thanks JT!

Personally, I would go with a BBB and machinekit for a 3D printer. This is
really based on size, but you don't need as much functionality with a 3D
printer.

These are good motors for a 3D printer. They have very similar specs to the
Ultimaker motors. I am just using them for testing as of now, but they will
eventually go into a Ultimaker clone, only different.

U possibly can use Cura for the gcode?

I start with my hal file from Stepconf. This is called
Gecko_540B4_TEST.hal I get errors when I try to add the line above.

It does work in the hal file from
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Parallel_Port_Tester

I can talk to each pin. This is what that modified hal file looks like.

ptest.hal
loadrt hal_parport cfg="0e010"
loadusr -Wn PortTest pyvcp -c PortTest ptest.xml
loadrt threads name1=porttest period1=100
addf parport.0.read porttest
addf parport.0.write porttest

It also works perfectly fine when I test it in Stepconf wizard. I
would assume something does not get carried over correctly to the hal.

It has to go near the top, before any HAL lines that try to addf the
threads and net the pins.

To be honest, I would start with the stepconf configuration, and add
your own stuff to that.

Hi Andy,

I swapped it out while troubleshooting.

So it works fine in Stepconf Wizard, but not in LCNC.

I assume I need to add "loadrt hal_parport cfg="0e010" to my hal file. Does
it matter where it goes?

It's a bit strange that it moved, the earlier lspci -vv had it at

Got it!!! With a little help from a friend.

He figured out 0x378 is for a on-board parallel port. Mine is a add on.

I do lspci -vvv and search for 9900 device. Then I use the first I/O port.

Caveat: I haven't even tried to use a parport for about 5 years...

I don't think that you can read too much into 0x378 not erroring, I
get no error with an explicit address on my VM which I know has no
parport.

You might find this useful:
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Parallel_Port_Tester

You need to alter the HAL file to change the base address, but at
least you can test with a voltmeter on the actual pins, or short an
input to a gnd pin to see the on-screen "led" change state.

Hi Andy,

I fixed the typos.

Linux ports 0 and 1 did not work. 0x378 seemed to load (it did not give
error message). I still cannot make the motor turn if I set Parport Base
Address to 0x378 in Stepconf Wizard.

Hi Andy,

Here is the hal load for port 0 and 1. They both don't load. I would assume
I am connected to linux "0" since they have different errors.

FYI: Last night I swapped card ports to see if this was this issue.

"loadrt" is a HAL command, not a shell command.

halrun
loadrt hal_parport cfg="0"

is what you would need.
(probably followed by

exit
dmesg

if it fails to load. On my VM I got:
[1297675.876520] PARPORT: ERROR: linux parport 0 not found
