Hello Ed,

I plan to thread the bolts with rollers.


Axial or radial? Axial would be awkward if they are already headed.






  The main concern for me was if the
1045 steel can be cold forged for this purpose of making the head of the
bolts.


I would look for Youtube videos, there should be several videos on cold 
heading that would explain different materials and methods.


 I used to have one bookmarked that showed how you placed the blank in 
a guide, the rolls came in from the side, the blank rolled a few times, 
and the rolls retracted.  I use axial rollers which have the blank 
rotating and the rolls are fed onto the part.

I think you are right. use_control_in is only set to 1 for X mode

If you are using LinuxCNC then just plug it in and configure with PnCConf.

You do not need to install any drivers other than the ones included
with LinuxCNC.

Re: [Emc-users] Parallel Port Driver Docs

[Joe Hildreth]

Thank you Andy.

  I think the driver works just fine.  I agree that the control port is 
bidirectional.  I would think that the entire control group of pins is set to 
either output (for modes in and out) and set to input (for mode x).  I am just 
trying to confirm this.  This is why I think there is a typo in the table in 
the docs.  If this is the case, can the documentation be corrected?  Honest, I 
am not trying to be a PITA.  Just trying to prepare accurate information for my 
next tutorial.

Wikipedia shows pin 14 as bidirectional.

I can't help feeling that someone else would have noticed by now if
the parallel port driver didn't work?

Part 3 of your question is recommended to download and install, the 
hostmot2 package, which will contain some, but probably not for either 
of these 2 cards, the files to program the fpga's, and the programmer 
sw. To get the exact fpga images for either of these cards, goto the 
mesanet site, and get the docs and driver packages for these cards.

A common fpga file that will give you the best for most jobs, is:
$cardname_prob_rfx2.bit. Follow the help instructions for mesaflash, and 
program the card, then do a verify run.

Add something like this to the bottom of your linuxcnc .ini file:
#*
[HOSTMOT2]
#  This is for info only 
DRIVER=hm2_pci
BOARD=6i25 (or 5i25)

If everything else is kosher, the card should sign on when you launch 
linuxcnc -l, showing you its available functions in the dmesg screen. 
The -l isn't documented, but means to use the last selected 
configuration in case you have several.

I'm running Master so its not in the terminal, but is in the dmesg 
output, and looks like this with my $config:

I realize it's a tad off topic but I think Bjorn Ekwall wrote the first 
parallel port driver for Linux a long time ago.  I worked with Bjorn in 2000 in 
the UK.  Bjorn died from a Heart Attack around 2001.  He was one of the Linux

[Emc-users] Parallel Port Driver Docs

[Joe Hildreth]

Hello all,

I have been working on a series of tutorial videos on YouTube on CNC for the 
Home Hobbyist.  In the tutorial I am currently working on, I am discussing the 
parallel port.  I want to give as accurate information as I am able.  My 
question is about the documentation found at [ 
http://linuxcnc.org/docs/2.7/html/hal/parallel-port.html | 
http://linuxcnc.org/docs/2.7/html/hal/parallel-port.html ] This documentation 
primarily talks about adding additional Parallel ports to LCNC.  It states that 
there are three modes in which LCNC can use a PP.  These are in, out and x.  It 
also provides a chart showing the pin direction based on the mode that the port 
is set in.

On this chart or table, it shows for the "in" column that pin 14 is an input 
pin.  I think this is in error and should be labelled as an output.  To test my 
theory, I installed a second PCI PP in a computer and run the stepper config 
wizard.  I set up the first port as output and the second as input.

In both output modes and input modes (for the ports) pin 14 is labelled as an 
output pin.  This would make sense considering that pins 1, 14, 16 and 17 
belong to the control group.

So if this is correct, then the documentation needs to be updated to reflect 
that.  If I am incorrect, can someone explain why this pin is input when the 
mode is set to input?

I also understand that in mode x, that the control port (pins 1, 14, 16 and 17) 
are set to inputs but at risk because the physical pins on the port may not be 
open collector.

If you are interested, the play list for the tutorials can be found here: [

https://www.youtube.com/playlist?list=PLaamliiI72ntlrHKIFjh2VjmehRGgZpjm ] I 
have 9 tutorials there and working on number 10.  The idea behind them is to 
give enough information over time that a new hobbyist can get into some form of 
CNC.  Rather than giving specific case examples, I want the information to be 
applicable to whatever they are wanting to set up.  Router, mill, plasma, 
lathe, 3D printer or whatever.  Constructive criticism is welcome, but I do 
give a disclaimer.  I am not a teacher, engineer or a machinist.  Just a home 
hobbyist who wants to give back to the community.

Thanks for your help and input.  It is greatly appreciated.

Re: [Emc-users] parallel ports configuration

I think that would depend on the machine you are placing the cards in.  A SFF 
(Small Form Factor) machine will require a low profile card while a regular 
desktop will take a full size card.

Re: [Emc-users] OT: Question about steel for cold forming

[Leonardo Marsaglia]

Hello Ed,

I plan to thread the bolts with rollers. The main concern for me was if the
1045 steel can be cold forged for this purpose of making the head of the
bolts.

I've machined forged camshafts of 1045 steel but they were made with the
hot forging method. I must say I have zero experience in the process of
forging, we only machined and heat treated the camshafts but the forging
process was made by another company.

First, you mentioned the PCI-e bus in your machine. The card that is 
virtually identical to the PCI 5i25, is the 6i25 in PCI-e form.  So that 
should solve one problem if your machine does not have both styles of 
slots available.

Second the std vs low profile is only in the cards back plate, and the 
choice is determined by your machine. If looking at the rear of the 
machine, the dummy card is around 4.5", thats a std profile, but its a 
low profile if only 3" and change.  I have in a pinch, made a plate, but 
it is a bit of cuss & cry sometimes. :)

Re: [Emc-users] parallel ports configuration

[yomin estiven jaramillo munera]

Hi, Gene. we have decided to use the Mesa 5i25 for our application, in this
case could you recommended us to use the standard profile or the low
profile?, so i would like to known, how is the installation process of this
card in the machine? thanks you.

Re: [Emc-users] So, how's Ethernet?

[Eric Keller]

Which Intel NUC did you get?  A couple of years ago I got a zotac box with
dual ethernet ports thinking that I might use it as either a router or to
drive an ethernet mesa board.  I think it will end up as a router.

Anyway, the Mesa card looks promising. Intel NUC and Mesa boards on the way!
