    Default Partner 1F w/ Centurion V first start up problems

    I recently picked this Milltronics Partner 1F up and got power hooked up to it today. I bought it sight unseen from a company that was using it up until about 6 months ago when, according to them, wouldn't home anymore. They decided they didn't want to deal with it and outsourced their CNC needs. I figured it could be as simple as bad limit switches or wiring, and for $1,750 I couldn't couldn't wrong.

    I first powered up the computer alone off of 120v. Besides a low CMOS battery, which after looking at has some corrosion and needs to be replaced anyways, everything seemed to check out. I need to get some floppies to save the parameters before the battery craps out, and a DIN adapter for my keyboard.

    Then I ran my single phase power to L1 and L3 and turned it on. No funny noises, everything seemed to power on. Sweet.
    On the control main page I tried the jog and handwheel buttons to move the spindle off the blocks used during transport, but got an Error 450 E-Stop Condition. Kept pressing Esc to exit the error.

    Then I pressed the Reset button next to the e-stop and the Z and Y axis both made rapid movements! The Z moved down about 4 inches from the table surface, which was still blocked with 3 2x4s mind you. And the Y moved back, past its limits and almost looks to be touching the back column now. Because they moved at the same time the wood managed to pop out.

    Now why would the reset button make those move?

    And I tried looking into the 450 error. Some threads saying that too much incoming voltage could cause problems. I checked my incoming at 239v. Will I have to look into some kinda of buck/boost transformer to lower it to 220v?

    Hopefully I'm not in too far over my head here and can get this up and running with some guidance.

    I'm no electrical expert, but your incoming power can be adjusted by changing wire connections on your transformer. Why it ran away when you reset the drives, I can't say for sure, but you might want to check the plus and minus 15V power supply for proper voltages. When I got my machine, it was putting out +15 but -24, so the imbalance caused me all sorts of problems related to the voltage imbalance going to the servo drives. I rebuilt that power supply with some parts off eBay.

    The CMOS battery... you will want to fix that. Mine had already lost parameters, so I had to type those back in by hand.

    Well I think I got it figured out, I actually had time to dig into it today. Took the belt covers off and wheeled the axis towards the middle of their ranges. The X-axis wouldn't budge at all at first, it was jammed up pretty well. Got it wheeled back finally and took a look inside. Looks like someone crashed it hard enough into it hard limit that it broke its mounting bolt off. I also found a mangled limit switch on the Y-axis. I just bent back into shape for now, I'll have to get one ordered.

    After moving them all back by hand I fired it up, and lo and behold I had the option to Home. Fingers crossed, hand over the E-stop, hit start. And she homed!

    Mangled limit switch.

    Little video of jogging each axis. X doesn't sound too great, what should I be looking at there?






    And for the CMOS battery, has anyone used that 4 pin header off to the right to hook up an external battery pack. I'd rather do that than solder in another battery.

    Update:

    Got air hooked up, heard some leaking from the tool changer. I'm waiting on tool holders still, but it ran through the tool change program fine as far as I could tell. Took the covers off and found the air leaking from cracked air valves. Ordered those (Parker PVLB1216067) and a couple limit switches (Panasonic Az-7141) for the y-axis.

    Hooked up a keyboard and got the parameters backed up on floppies. Still waiting on the battery holder to replace the CMOS bat.

    Now I'm trying to diagnose the x-axis noise. I slathered a palm full of grease on both ends of the ball screw and slowly traversed the table back and forth. The noise is still there.

    Id like to unbolt the ball nut to see if that's it or the thrust bearings, but I can't for the life of me think of a safe way to take the springs off the x-axis way covers, and get them back on afterwards. What's the best way to get those guys off?

    New way wipers came in today. After some searching I ordered what I thought would work from Dynatect, TFW-1/8. You get 5' for $25. Fit perfectly.

    Also got the external CMOS battery put together and installed. Installed with the machine on, then moved the jumper to EXT. Cycled power, and no more CMOS issue at start up.
