    Bob,
    That is looking very nice. It looks like you are making great progress. I like the way you have taken into account ongoing modification and maintenance.
    Looking forward to seeing some wires connected soon. ;-)

    Thanks Dave. I appreciate you posting just to know someone is reading this.

    I don't know whether to do just the bare minimum wiring to get some movement so I can see if the problem still exists or not. After everything I've been through I sure would like some confirmation the direction I'm going is Forward !

    Still lots of things to do before I start final wiring. Mounted another terminal strip for 5 and 12 volt feed through from the power side and (crudely) mounted the RJ-45 panel jack for the Smooth Stepper.

    I need to finish the mounting of the Super-PID and mount the Power Supplies.

    On the plus side I don't think there is much in the way of design considerations to slow me down. Those are done and hopefully will pan out and the rest of the control box assembly will be smooth.

    Bob,
    I guess its how confident you are in your solution working? ;-)
    I would approach this very systematically since you had issues before and work step by step verifying that things work bit buy bit. Its a fairly complex system and you need to identify the root cause of your failure and ensure it is resolved.

    If it were me, I'd set up one axis at a time and verify that it's working correctly before going any further.

    I don't know about how confident I am about the 'solution working', but I am confident I am removing lots of potential for problems and will end up with a much cleaner install, and a smaller parts count. I will have to hope it's enough.

    As I am running the Geko's via motherboard and ribbon cable arrangement I assume it's OK to run the Geko's without motors attached?

    Bob,
    You might want to check the manual but I believe you can run without a motor. The big issue I think is connecting or disconnecting a motor when powered up.
    I like Gerrys suggestion

    Almost ready to start wiring

    I got a rare weekend in the shop and am making good progress. I thought I would already be wiring by now, but it was one detail after another that needed to be taken care of.

    Unless I'm missing something I am really stoked about this case setup. It is going together really slick and easy. It just sort of fell together. I think the level of access will be a bonus.

    The SuperPID speed control is safe behind a lexan window cut into the front panel. The power switch is mounted so the front panel pops off easily. It was very easy to mount some captive nuts for the front panels. There is a piece of angle aluminum at the top used for a heatsink for the SuperPID. It is not touching anything other then the heat sink tab on the SPID.

    I found a piece of DIN rail to mount the contactor to. I want to order some breakers/fuses to mount on there if I can figure out which ones to order. Some of those ordering pages get mighty confusing when you've never brought this stuff before.

    I mounted a cable carrier purchased from surplus. There's a place local that has all kinds of stuff. A lot of the pieces parts for this case came from there. I'd fill a small paper bag with items and he'd give a price for the lot. You never know what your going to find in this place.

    The logic side should look great compared to the rats nest of the old one. The RJ-45 connector on the back will feed the Ethernet Smooth Stepper mounted to the PMDX-126. Ribbon cables feed it to the PMDX and power the ESS. Ribbon cable to the 4 main Gekos. That's alot of wiring NOT needing to be done. The terminal blocks will provide power to the PMDX board and the other one will provide DC voltages to the logic ( along with whatever else needs to be routed to the other side.

    Stil haven't stareted wiring yet, but...

    .. I have cleaned a few things up. I was originally planning on putting the AC for the router on the bottom rear panel on the power side. That's why I originally cut that panel seperate. Anyhow, I decided that with the cable carrier why not put the power outlet to the router where it would work better, so I went to the local H/W store and bought an outlet and installed it.

    Also, since I realized I never posted a pic showing that the logic side is easily removeed I posted a pic showing the full level of access to things.

    Also, I am thinking of re-making the cable support, if I can find that piece of left orver rod around here.

    One more thing, Killian's is tasting goooooood !!

    Comments welcome,


    BobL.

    Bob,
    That is looking very nice. I like how you have separated things.
    It will work better once you put some wires in ;-)

    Some wiring done

    Not too many pics today.

    I went ahead and made another cable support bar to provide a little more room where the cables route.

    The wiring shown in the pics provides the ethernet connection to the ESS which supplies the equivalent of 2 PC Parallel Ports to the PMDX via short ribbon cables. The PMDX feeds the 4 main Gekos with another ribbon cable. The Geko motor outputs are fed to the rear panel along with cable for 4 Limit/Home switches. That's actually quite a bit.

    I need to supply 120 VAC to the PMDX, terminal block in place, and route the 50VDC to the Geko motherboard.

    AND, the case still slips on easily

    BobL.

    P.S. Cables are run for two additional Gekos and I've got room for 6 more connectors on the bck panel .

    Very nice Bob.
    All your planning is coming together.
