Re: Tool offsets change after restart

No immediate ideas. If you double-check tool positioning (e.g. with an MDI Tnnnn / G0X0Z0.1) after running for a while, but before shutting down, are they all still on position? If you make note of the numeric values for your tool offsets (both geometry offsets and wear offsets) before shutting down...

Yes. Between 7-3/4" and 8" diameter, ca. 16ga steel.

Re: Drawbar Proximity Switches

The switches themselves ought to be normally open. "CNC12" isn't looking for anything, one way or the other. That logic is all in your PLC program and associated CNC macros. If you post a Report, then we can look at your PLC program and macros. It is highly likely that your PLC program and...

Re: Mitsubishi Freqrol A500

The A500 will do that, but only in closed-loop vector mode using encoder feedback. I do not know of any VFD that can hold position without encoder feedback.

Re: Control Cabinet Inlet Fan

I put 3/4" plastic spacers around the fan opening, with a bridge running diagonally across to hold the cover stud. The screws that hold the spacers in place also secure the fan inside the door. I tap the corner holes in the fan: 10-32 on an english cabinet, or M5 on a metric cabinet. The plasti...

Re: Spindle encoder calibration

That is the "Max spindle (high range)" value on the Control Configuration menu: F1/Setup -> F3/Config -> F1/Control 3000 RPM is a value you put in temporarily, to run the bench test. Later you will change it to reflect what you have programmed your spindle drive to do, within the limits of...

Re: Alarm code 549

N numbers are not required. If they are included, and if "fast branching" is enabled (Parameter 145 is 1), then there should not be duplicates. With very long programs, and no "GOTO" statements, you should turn "fast branching" off: set Parameter 145 to 0. If he still h...

Re: Tool Length Sensor

It sounds like the program that is loaded when you press Cycle Start is not the probing program generated by ProbeApp, but instead is a previous machining program.

Always look at the current Job Name displayed at the top right of the screen before you press Cycle Start.

Re: Control Cabinet Inlet Fan

I have used a lot of those same fans and filters. In particularly dirty environments, or where maintenance and cleaning are likely to be neglected, I use an automotive air filter. A NAPA #2906 filter fits reasonably well around the opening for a 120mm fan. This provides more air flow, more effective...
