Hi!

I have a tool change issue with my 1989 Bridgeport Interact 412, TNC2500. When machine is started, the first M06 procedure runs correctly, the turret is turning without any problem.
When I run M06 for the second time, the cycle doesn't finish.

This is what happens:
1. Z axis moves to the top position
2. Spindle doesn't rotate to home position (I hear just a click noise)
3. Z axis goes down to tool change position
4. Machine stops, no error, only shows blinking * symbol

Sometimes in step 2 the spindle just rotates tiny bit and directly moves to step 3. Seems to be a random thing.
At the same time the M19 works perfectly fine.

I tried running a program with tool call function as below. Same situation as with M06 in manual mode. Sometimes it worked and it performed full tool change cycle, but then the second tool change will get stuck in same way as described before with M06 in manual mode.

BEGIN PGM 1001 MM
TOOL DEF 1 L0 R+0.5
TOOL CALL 1 Z S2160
R F M06

The machine was working just fine in the beginning. Then it was stored for two months and moved to a new location.

Any help will be appreciated!

It sounds like the spindle orientation is off sometimes when the tool change fails try turning the spindle slightly by hand but be careful. if it works the the spindle orientation card needs adjustment

Thank you for the suggestion, I will try turning it by hand. When it comes to the orientation card, which adjustment parameter should I start with?

please do not turn the spindle much because you need the key on the spindle to line up with the tool change I would just wiggle the spindle slightly and be careful and use your right hand so you can move it quickly when the tool changer slide towards the spindle.. I had the same issue with my 412.

The spindle orientation card is located in the side cabinet look in your manual it will explain how to adjust it.

Good Luck
