[daewooDmv3016]

Hello all,

I got an error during the middle of a program run. The error is a "No.2079 Tool Magazine Synchro Malfunction". Now, I've had this error before and I was able to do the following:

************************************************
Side Mounted Tool Changer Recovery (Submitted by : Philm)
1. Restore Power (It is not necessary to Zero return the machine)
2. On the Automatic Tool Changer (ATC) box at the back of machine, set switch to
manual.
3. In MDI key in M39; and press the start button. (This starts maintenance mode and
allows you to use the 2 keys for rotating the tool magazine as jog keys for the tool
changing arm.)
4. Turn mode switch to JOG
If you have a tool in the spindle make sure that the tool is unclamped (Green light on). If not, manually press tool unclamp button.
5. Using the jog keys (on the ATC box) move the tool changer arm to home position (you will have to press the key several times). Carefully watch the tool that is being placed in the spindle. Once it is in position in the spindle manually press tool clamp before proceeding otherwise the tool will drop. Finish pressing the jog key until the arm is at home position.
6. Turn mode switch to MDI
7. In MDI key in M19; and press the start button (spindle orientation)
8. Key in M41 (will complete 1 complete tool change)
9. Set APC box back to Auto.
10. Check to make sure that you have the correct tool number in spindle before
continuing.

However, this time it's a bit different. The pot is only 1/2 way down on a pot down command. It'll go back up fully but when you do pot down again, it comes half way or so only. I also can't get my manual CW / CCW buttons to work in the ATC box in manual mode either.

Any and all help is appreciated.

if the pot is not completely coming down i would expect there to be something mechanically wrong with the pot up/down mechanism
