    is that all you have to do to make mighty drive work. Remove pin 25

    This is what i found and it works for getting spindle output relay to work.
    Setup Mach3 to use output to pin #9 (read setup on spindle noted on Mach3 website)
    Pin #9 on serial port on computer is a output on and off of 5 vdc.
    On Microkinetics Mighty Drive Pin #11 is a input requiring + 5vdc on and off to activate and deactivate solid state relay.
    unplug relay inside mighty drive
    what i did was remove wire from pin#9 on cable ran the wire to solid state relay on positive side.
    for a ground i ran it from shield on plug to negative on relay.
    Now thinking about it I think I could of simply soldered pin#9 wire into pin#11. Not sure.
    You will need a plug that you can take apart to acess these wires

    As I have time today or this eve I will look over the documentation I just downloaded the for Microkinetics hardware you are using and will give u my opinion on what to do. From what I saw at a glance you should have no problems doing what I did and freeing yourself from the antique hardware and software. First thing first though: ***** DO NOT PLUG YOUR 25 pin CABLE INTO YOUR PARALLEL PORT ***** The mighty drive box (same as my SuperDrive box, sends +5 volts out on pin #25 and -5 volts (aka ground) out on pin #23. This is where the OptiStep card gets its power and subsequently will send step, direction, and output signals back to the mighty drive box. Your parallel port has pin numbers 18 - 25 all internally tied to a single ground. If u plug your 25 pin cable from the parallel port to the mighty drive box you will pop a 3 amp fuse inside the mighty drive and nothing will work. So, for now go get you a male to male Db25 pin parallel cable. I found them all day long on eBay for about 10 bucks. Once you have that cable, you will need to physically remove pin # 25 from each end of the cable. I did it by simply wiggling the pin back & forth until it snapped off at its base.

    More to come,

    I poster you to say thanks for the post. I am not sure but I may need help working this forum this is my third attempt at this. I have my machine sheet metal and paint done and just recieved the laser tube and power supply. More wires. I am a little nervous about changing it to Mach3 but I dont know how to make Microkinetics controll 5v for TTL low and so far I don't think they know how eather. It will fire soon and then I will have to do something!!
    Thanks again

    Nutron. I have a vintage Torchmate that I built from a kit in the late 90s. I have made a lot of money with it but have always hated the DOS Superscribe program, the floopy disk, beater computer with the floppy failures, etc. I want to do what you did. Hopefully, I can figure it out from what you have said here. It took me a loooooong time to figure out CorellDraw and the quirks of this machine, so I'm hoping my 10 years experience will make it easier this time. So, Mach3, replace the Mighty Drive with a Superdrive box and get rid of DOS, Superscribe, the card in the computer, the floppy drive, etc. Sounds great. I don't quite understand the part about breaking off the pins on the cable, but I'll go back and read it again and maybe a bulb will go on in the old noggen. If I need some more tips, is there an email where I can contact you? This is my first time here and I'm not sure how things work. Great post by the way.

    A bump to ask about that solid state relay...

    I wired straight across pin 9 to 11, it worked and got my outlet turned on my mighty drive powered microkinetics 5400 mill. Problem is, it's backwards--should be off, but is actually on. I'm wondering if your method by actually changing the polarity on the relay was a better plan? If I can't find a way inside LinuxCNC to reverse the switch output then I'll crack the box open and look at how it's hardwired.

    I just found this site today. I have the exact same system that you have. It has set idle in the corner for a long time because of the old MSDOS operating system. Like islandman 18, I am having trouble realizing exactly what you did to change the old Torchmate Plasma cutter into a Windows XP and Mach3 system using the superdrive box and the 23M800 stepper motors. Correct me if I am wrong but you installed Mach3 in a computer using windows XP, broke pin #25 off in a parallel port cable plugged everything in and it worked?

    This is the exact same setup my boss picked up for a homemade table. So far, I've been less than impressed. In addition to this system, there appears to be a PLC to really muddle things up with tons of cables in a mishmash soup of "this works just fine" mentality. /sigh

    To those that are confused, just take a look at the wiring diagrams for the pinouts; they should give you the information that you're looking for. Once I break in to the circuits for this, I'll have a better answer for you, but atm, I'm way behind and won't have an opportunity for several weeks to dig in to this issue. Looking at how things are wired, though, it doesn't seem difficult to fix the issues, it's just figuring out what the issues are.

    Additionally, I've steered away from using MultiCAM which I found to create clunky g-code. Instead, I've been using SheetCAM and a custom Post Processor I'm building from the other ones. I've found, if you need the information, that MillMaster seems to operate similarly to Amada or BOSS4/5 which both use Fanuc as a parent language. It'll need to be edited still, but it'll getcha 80% or so.

    Cheers!

    I am working on a superdrive microkinetics to mach3 and have run into some trouble... I rewired the parallel port to more of a standard wiring the on off for the plasma cutter works great but I can not get the stepper motors to work ..they just hum and heat up ... I have tried a on board 5v power and USB cable 5v from the computer with no luck ... anyone gotten this to work? If so how?

    Got it working .... sorry for the post before

    You do need to rewire the plug on the back of the unit and it needs 5 volt signal to the driver boards from the computer .. I used a USB plug to steal the power...

The Parallel port has replaced that antique card that connected the PC to the SuperDrive power supply/motion controller box. This weekend I will get some pictures and a schematic of what I changed posted. I am sure we can't be the only two with these older setups that would like to upgrade without spending a fortune.
    I have this setup, did you ever post the pics and schematics for this?

    thanks
