    Also the floppy shows zeros for 240 to 242.
    What I should look at is the parameters actually in the machine.
    Since I didn't re-enter the parameters couple weeks ago, I don't know how to check the parameters in the machine. (My technician re-entered them).
    What buttons do I press to check parameters in the machine?

    I was thinking you need a subprogram 09001 for tool change but if the parameter is empty it seems that you do not need
    did you tried another tool call?Maybe you have tool 4 already in the spindle and that is why the machine do nothing
    i think for MDI comand is M06 ->Input,T01->Input
    did you load all the diagnose or checked with floppy if it is corect?
    diagnose from 300 to 600

    Other issue i have i think is the limit switch on Z axis. I think its an over travel issue. I tries to override this with the red button on the side of control panel, MPG, Low X1 and +Z but no go.
    So question is, is the limit switch basically a button which gets pressed in on the Z travel slides? If it is a switch it feel solid and stuck inwards.

    If it is over travel alarm, need to remove the alarm first, then move the Z axis back in range manually.

    yes that all fixed. Thanks
    Im trying to find out why i cant get the tool changer to work when i enter the command in MDI. zavateandu seems to think it may be parameters form 300 to 600. And should check.

    is not parmeter,it is diagnose that in many cases is related to tool change

    btw,
    Make reference on Z AXIS than try to move the z axis to tool change position by typing in:
    G0 G91 G30 Z0
    than try again the tool change

    I zero'ed all the axis first
    Press MDI
    I typed in, G0 [INPUT] G91 [INPUT] G30 [INPUT] Z0 [INPUT] [EOB] M06 [INPUT] T4 [INPUT] [EOB] [START] but no go


    I type the code in this screen

    For some reason the relays for the air lines to ATC are not switching. I can manually switch them by pressing the air actuator by hand and the ATC moves so mechanically its ok.
    These are the voltages to the relays on the air actuators, I hope you can help me if its correct?

    Hi guys, seems success comes in small stages.
    I found the carousel motor was very hot, I pulled the carousel motor out to see if it would rotate during tool change command to prove the motor/command is working which it does.
    I found the carousel was physically jammed which stopped the tool change and heated the motor. I freed up the carousel and its turning. The motor, which turns it, was very hot and I thought damaged but its ok.
    Unfortunately, it’s still not changing tools, basically it turns the carousel and I thought great, but it turns in one direction then the other direction continuously, it’s like it doesn’t know where to stop. Also the tool changer doesn't go down or accross.
    I see there is a magnetic sensor next to the carousel motor wheel. I’m thinking should the magnetic sensor and the wheel (Encoder wheel for sensor) should it be in a particular position so it’s timed correctly to the magnetic sensor??

    Hi guys.
    I must be doing something wrong. I tested the relays which activates to tool changer and all ok.
    So the question is while in MDI how do i test tool change? I don't have a program loaded yet.
    Some machines just need the tool change command M6 T5 Cycle start.
    Others need P for Pot when looking for a pot without tool in it the pot. M6 P5 cycle start. (HAAS) while in MDI i think.
    Am i getting this mixed up? Bit lost at the moment why tool changer not working.
    I have an old Leadwell MCV OP Fanuc controller

    Hi Zavate
    Sorry I haven't contacted you for a while, i still haven't been able to use the tool changer yet. (I've been using CNC as manual mill at the moment)
    I have been trying to get the service manual for my machine with details on the ladder. I haven't been able to get the service manual yet unfortunately.
    I do have a video of some of the ladder from my machine if that helps? (regarding the tool changer not changing tools).



    Thanks
