A Treatsie on the Parallel Port - HP Elitedesk 800 with generic cable

Ok boot on the installed system and run the following lspci command

The other two can stay the same. And can you post the full ioport output

Not to be obnoxious, but isn't there just a known good PCIe card that I can just buy off Amazon hat just works with LinuxCNC, preferably with support already built into the kernel?

Going by the PCI Id of the card it should be supported by the std parport_pc driver.
For some reason it’s not and neither is the vendor supplied driver working.
No your not being obnoxious, it’s just frustrating, so it’s all good.
Generally NetMOS based cards are a good bet.
www.amazon.com.au/Syba-SD-PEX-NM2P-Print...hipset/dp/B000RK89ME

Something similar to the above, a little more than what the star tech cards go for, but you do get 2 PPorts on the one card.
It’s also worth trying the Parallel Port tester utility mentioned above, at least you can select which pin to test at a human readable rate.
I really wish you well it’s a bit of a journey finding a card that works.
Cheers
Rob

I can't get that board in the US, but what do you think of these:

I suspect it would work if enabled, check out this thread:

forum.linuxcnc.org/9-installing-linuxcnc...inuxcnc-2-7?start=20

Near the bottom (adouglas89s post) there is a method to enable the disabled ports.
 

The first 3 have a NetMOS 9805 (whic the wiki advises to avoid)chip and the 4th has the same Ax99100 chip.
wiki.linuxcnc.org/cgi-bin/wiki.pl?Parallel_Port_Cards

Some good stuff here:
forum.linuxcnc.org/18-computer/18917-faq...-parallel-port-cards

Below are 2 NetMOS based cards I could find on Amazon US.

Just a bit of a thought.....
One thing that is worth thinking about, is how many parallel ports one can try before you're at a similar amount that a simple Mesa 7i92 card can be had for. Which doesn't have the need for a base thread (latency is so stringent), connects via ethernet, basically gives you the equivalent of 2 parallel ports, is very well supported and from my experience gives you a smoother running machine. With suitable firmware it is very easy to use with the standard Parallel Port breakout cards.
Another plus as well, if it comes down to it a Mesa card will have great resale value.
The ethernet connection is something to think about for later years if your current PC has any hardware issues.

Thanks PCW, I tried looking for that info last night but couldn't locate it.

PCW, that might have been a winner!

I am still running on my Live distribution because something seems screwed up with my installation and I can't re-install for some odd reason, however:

I tried:

cd / /sys/bus/pci/devices/0000:03.2
sudo su
echo -n "1" > enable

Then installed the driver with io=0xd010, io=0xd000 irq=18

I went into LinuxCNC and ordered a 5mm move on X, and when I monitor pin 2, I see a series of 5V pulses that are roughly 3.5 microseconds wide and spaced about 5.1ms apart.

I tried connecting the router (CNCEST 6040 Chinese, bog standard) and...

Z-axis seemed to work, albeit it seemed like it was working in the wrong direction (is -Z = up or down typically), very slow, and probably less movement than it should have been -- I presume thi is just configuration, no big deal.

Y-axis made noise when going in the + direction like the motor was doing something but there was no actual motion. I think I may have seen the leadscrew occasionally jump. When I went in the - direction there was a constant alarm sound which stopped if I hit the "+" after a second or two. Perhaps it was hitting an endstop?

X-axis didn't seem to do anything, at all, no noise, no motion, etc.

I couldn't get the spindle to work at all from LinuxCNC although it worked through the box.

FWIW, I bought two different ones from Amazon so that I could return it if it doesn't work, however, the Startech AX99100 now appears to be "working" so that's good and it seems to have pretty decent performance.

The remaining (off topic) question is, how do I configure it? I appear to have DJK-01A BOB (which may also be called a "Tonsen 4 Aixs [SIC] Con[troller]" it's driving 4 TX14207 stepper motor driver cards, the fourth being to run a "lathe" unit and is "A."

I found this post: www.mycncuk.com/threads/6922-Tonsen-4-Axis-Controller-Bob which includes a schematic.

Is it as simple as CK = Step, and CW = direction. What about enable (is there a separate enable for Y/Z vs A/X)? Is there a way to control the spindle or is that purely from front panel?

That probably explains why my X-axis doesn't work since it's pin 16/17 not 2/3. But not the weird noises from the Y-axis.

• A
  • EN - enable - DB14 - shared with X enable
  • CW - dir - DB-03
  • CK - step - DB-02
  
  
• Z
  • EN - enable - DB-08
  • CW - dir - DB-06
  • CK - step - DB-07

  • CK - step - DB-04
• X
  • EN - enable - DB-14 - shared with A enable
  • CW - dir - - DB-17
  • CK - setp - DB-16

DB 10 - 11 - 12 -13 - 15 Inputs via opto couplers
DB 1 5v output marked as Motor

If I was wiring this, assuming a 3 axis mill with no rotary axis nor a slaved axis as in a gantry:
The enables for X Y Z I would not connect to the stepper motors, most simple machines use this method.
Connector A I would use for the spindle with PWM output on CK, CW for forward and EN for enable. Tho you could use CW for forward and EN for Reverse depending on the spindle itself.
Connector "MOTO" could be used for any needed output.

IMHO the naming convention for the connectors doesn't conform to the "defacto standard", Pins 2-9 for axis x-y-z-a. Honestly this looks like a poorly designed board. The 1N4007 after the 5v regulator with drop that voltage to 4.2 to 4.4 volts.
The 15v reg isn't really required if you were to supply the board with 8 to 9 volts. This would be a product I'd wouldn't be inclined t use. If you have it it should work, but you'll want to keep careful notes of the wiring.

Even the schematic isn't 100% clear What be be assumed to be resistor networks marked RN1 & RN2 are only shown as standard resistor. Generally I like to use buffers for at least all outputs, where as only the step & direction have buffers, the enables don't (which generally are controlling the same type of opto isolator on the stepper driver as the step & direction).

Not too usre if you are in the UK or US but if this is your first build I tend to opto for one of these
cnc4pc.com/c35s-breakout-board.html
I've got one at home I use for testing and found the docs, build quality & design quite good.

Sorry if I sound like a bit of a downer, but just some things I've noted.
