I have a Shopmaster Patriot 2011 that came with a Dell computer loaded with Mach3 and Wondoz. That sent signals to a Camtronics built unit via a C10 Parallel port interface to Geckodrive 6203V Stepper drive. The Dell PS died, the HD about died a few years back. I grabbed a new PS, used clonezilla replacing the HD with an SSD.

Because of CORVID-19 I have a huge amount of home time to do what I wanted way back then. Get rid of Wondoz.

My goal.
  • Replace Mach3/Wondoz with LinuxCNC/Mint.
  • Replace the C10 with Mesa 7i76e

I received the 7i76e card yesterday and so it begins.

I'm not savvy with non RedHat Linux variants, LinuxCNC or electronics for that matter.

This thread could get interesting.

Hopefully I escape the white smoke.

Attached is what I will be working with.

That should be easy enough, remove wires from BOB and attach those to 7i76E, power the 7i76E, install Linuxcnc and make chips.

I downloaded the Mint variant on this forum and started guessing at the best process to install a conservative release of LinuxCNC on this thing.

The process (seems like there are 50 ways to get said point) this is my first stab at it:
  • Download a spin of Mint from one of the LinuxCNC threads
  • Threw the ISO on a flash drive from the Mac
    sudo dd if=./linuxmint-19.2.0-20200306-LCNC-2.8-RT-UEFI-mate-64bit.iso of=/dev/disk2
  • I got a little stuck here not knowing what is the best strategy.
    • git clone -b 2.7 github.com/LinuxCNC/linuxcnc.git linuxcnc-2.7
    • cd linuxcnc-2.7/debian
    • ./configure uspace
    • cd ..; dpkg-checkbuildeps
    • sudo apt-get install ... packages ... # At this point I am wondering if I derailed because I am using a custom ISO for linuxcnc installing packages
    • dpkg-buildpackage -b -uc
    • sudo app install linuxcnc-uspace
    • linuxcnc &

On to the Camtronics and the C10 to 7i76e.

I made mount/(Corvid-19 Home Lock Down hack) made from materials in the garage and past projects back in the 80's...

Attached is a CAT-5 to parallel Male to a parallel Female to CAT-5 plugging into the 7i76e board.

I tested the config on the home network and it seems to work just fine.

  • I wonder what made you think you need to do that ? There is no need for anything under that line, just boot and use as live, or install to hard drive and start Linuxcnc.

    I will take a look at that.

    I am newish to Debian flavored ice cream. Kinda avoided it as much as Wondoz. Not new at all to Linux but that never means I don't learn something everyday :-)

    I tested/verified the 5v source that was going to the C10 and sent that to the 7i76e P3 plug.

    I am now onto where I run out of talent and onto remove/replace.

    C10 has the following set on the jumpers.
    • COM 1-2 GND # I'm Ok here
    • Pins 2-9 Pull down # I honestly do not know at this time what pull down/up means.

    The 7i76e has something extra from the C10 that I am not getting.
    Pin 1 GND # I am Ok with that
    Pin 2 STEP0-
    Pin 3 STEP0+
    # I am stuck...
    Pin 4 DIR0-
    Pin 5 DIR0+
    # I am stuck....

    Step and Dir the - + option.

    I am going with +, it sounds so much better than - today.

    I wont throw the power till I understand this better.

    Any advice is totally welcome.
