    That is a huge part of a production mentality.

    IME, it is shops that only use their machine(s) for the occasional prototype build or rework/mod job that do little PM work.

    It's a 9 pin PC to 25 pin CNC cable set up to use hardware handshaking.

    For uploads and downloads with a CNC control's memory a 3 wire cable and software handshaking usually works fine. For...

    Terminology can be a bit messy here. APC can denote Absolute Pulse Coder and also Automatic Pallet Changer. In the OP's case, I am sure all these batteries are APC batteries for the pulse coders.

    Hard to imagine an aluminum bracket the size of a mount for a tool probe to change that much. Ever look up the thermal coefficient of expansion of aluminum?

    Does your shop have such large temperature swings to affect the repeatability of measurements? If you do, that might be an area to explore getting under control. It's gotta be hard being a world...

    Do you know how to monitor the ladder? If so, look at outputs Y1A8, Y1A9, Y1B0, and Y1B1. These are auto interlock signals for positive and negative travel of axes 1 and 2 (XZ on a lathe). They...

    M01 0004 alarm means that an external interlock input has been read by the PLC and sent to the CNC. I'll try to get some time tomorrow to look at how that is implemented in the ladder on my machine.

    Quite often the case when thermite notices a thread. I suspect alcohol and an old man's memories may have something to do with it. At least that's what causes me to ramble occasionally.

    And 40 taper is so weak compared to 50 taper. I don't get the constant 30 vs 40 taper argument. They have different capabilities. Each will outshine the other when playing to their own strengths

    Many of the parameters will be very specific to that machine. Unless you find someone with an identical machine to get them from, you should try getting them from the manufacturer.
