I've rebuilt a YANG SMT500 and busy with commissioning it.
I'm new to the machine and never actually run it before.
The tool changer has 2 issues.
Stops mid code
Sometimes a loud crack when releasing the tool.
It does appear that setting G54 parameters upsets the process, but I'm hesitant to try too many options so as not to break anything.
Here is the Auto tool changer program
Code:

21 G0Z-74. Z Rapid to -74
22 G1Z-60. Z Feed to -74, (Rate 4000 from above)
23 G28Z0. Zero return the tool to its zero position via a reference point at rapid speed

Line 17 Move Z to 60 mm Which reference is this ? Machine Zero or G54. It must be Machine Zero but where is the G54 disabled ?
Line 15 M86 - Is this maybe a canned cycle for the tool change ?
Is there a Fanuc parameter that is set to know if the coolant was set on or not ? Maybe M86 and M87 are those parameters.
