I am interested in what comes from Omni Vision.
Does that include the sheet-metal framework?
Does it include the power supply?
Does it include the bezel?
A version we saw some time ago did not...

Running that spindle configuration in low gear relies on parameters that tell the control exactly what the high-to-low gear differences are.
Did exactly the same kind of transmission get replaced?...

The problem here is that G95 will not move if the spindle is stopped.
And tapping starts with spindle at zero speed and ends with spindle at zero speed.
So the note below saying to put the G95 on...

Be aware, please, of one more thing that causes beeps.
With machines to Europe or domestic since January, there is a door lock.
It unlocks at end of program or when spindle stops.
It tells you it...

But...
You can disable this check and the alarm with bit 12 of parameter 278.
The name is "uP ENCLOSURE TEMP".
Set the parameter to 0.

You can't fix this with software.
If the sensor is broken, there is no software that fixes that.
If the sensor is working, you would not get the message when it's not hot.
There is a display of...

You also need to be specific on what is happening.

1) Is the entire machine turning off - that is contactor in back releasing?
(this could be a power problem or settings 1 or 2)

2) Is just the...

Please keep in mind that there is now a "setup mode".
The key-switch on the side of the cabinet can be used to select a mode where the door can be left open for some functions. This includes...

There are several issues with this.
First is that there is no G code to support it.
And... it really is hobbing.
Another is the spindle encoder resolution.
At 4000 parts per rev, it does not have...

I think I see a problem with the way you are writing macros.
There is a peculair effect when mixing macro variable references and normal G code.
The macro variable references are all executed frist...

This sounds like an older machine. A 1997 or earlier?
Those had a mechanical air-driven shot-pin to hold the spindle stationary during a tool change and a switch to sense when it is seated.
This...

There is an intensity adjustment for the CRT. Depending on the model, it might be on the side and accessible thru a small hole or it might be on the back. You might need to take the cover off. If...

Sorry.
This does not look like it is going to be simple.
If the PGM light is on, it found the software and it passed a CRC check.
That means it would not help to re-load the software.
The PGM...

There is a row of red LEDs on the processor board.
They come on is sequence as the machine starts up.
The PGM light says it found the machine software.
The Halt light says processor has a serious...

You might look at a nearby thread/forum where they demonstrated that HSM cures all ills with short linear moves.

If you got power by using the 240 volt circuit to ground that is the problem.
That is a three-phase power system.
Ground is not at half of 240 volts.
Depending on your power, it could be anything...

I still don't understand how you wired it.
The two leads from the control supply 240 volts.
If you connected to just one lead, where did the other lead of the motor go?
See earlier description.

I'm sorry.
I guess I don't know what you are doing.
The Haas coolant pumps are all 240 volts.
If you are trying to use the standard circuit to run a 120 volt pump, you must have done some custom...

Did you check the breakers at the top right of the cabinet?
The GFI is for low voltage (120VAC) stuff.
The IO board is blamed for a lot of stuff but is not always the problem.
What output from IO...

Those look like the right range of numbers BUT the sign is important. One is negative and the other is posiitive. It is still best to get the same numbers the machine had at shipment. The...

Also might check old parameters from original board and use parameters 138 and 139 from there.

What software version do you have now?
Parameters 138 and 139 are used to compensate for reversal.
Use of these parameters really requires a ball-bar setup to check the results.

Turning on HSM is not just changing lookahead from 40 to 80 blocks.
HSM really is all of the things needed to make lookahead work.
That gives 80 blocks of lookahead.
Without HSM, you don't get any...

All of the symptoms you have could be a power supply but are more likely a cable problem still. These things flex continuously and after about 13 years, something can break. Look very carefully for...

The biggest problem with RS-232 reliability is insuring the machine tool and the PC have a good common grounding system. If the earth ground to either chassis is missing, a big electric motor nearby...

If you are now getting "Y zero return margin too small" that's probably because the motor was removed and re-mounted clocked a little differently. That should not happen for keyed motor shafts but...

Yes, data out is on pin 3 with common ref on pin 7.
There might be some older units that swapped pins 2 and 3.
Still... disconnecting cable from control should result in any "send" finishing in a...

The single axis control transmits in the recieve wire.
It recieves on the transmit wire.
That is, it is wired as DCE; not DTE.

If it hangs at "sending", something has stopped output.
Normally sending takes a few seconds and all data is out.
That kind of hang has only two causes:

1) X-off character sent from PC telling...

Try some simple things:
1) with PC connected and Terminal running, send program from control. It should appear on screen of PC. If not, check for reverse of Tx/Rx.
2) If #1 works, try typing in...
