If you didn't see it running, it may pay to check that all of the boards are correct for the mother board - they may have swapped boards. See attached board compatibility chart.

Go to Control Panel->System->Device Manager-> and look for the com port used for transmitting the program. Make sure the baud, parity and other parameters are set up exactly as they were under Win7....

Here is a PDF that lists control card compatibility. Given the age of the machine, there may be other cards required if upgrading to a -4 or -5.

Has anyone converted from Vactra No 2 way lube oil to a synthetic? If so, any recommendations?

Thanks,

Jon

Ran across this spindle fix several years ago - not for the fainthearted.

You might look at the resolver. My 4020 had one axis that generated a high follower error that could not be adjusted out. The resolver was pulled and had a bad bearing. Once replaced, the follower...

The first bitmap in the zip file is for the computer setting on XP64. The remainder of the bitmaps are from the Predator program supplied with CamWorks. The computer is hooked up to a 1987 4020 with...

Have you verified that the port is set to the correct parameters? On XP, control panel->system->hardware->device manager->ports (com & lpt) ports. Select the port that has the Fadal cable, then look...

Rodney,

Fantastic! You are the man!

For the past two days, the 4020 has powered up without incident - with the ambient temperature now <80F in the morning. After being shut down at the end of...

Powered on this morning and received the SCALE message. Shut it down, directed the air conditioner to the card cage for 15 minutes, and then powered up OK. Ran it all day, shut it off, and then...

There is no plug on J13, and examination of the rear of the board behind J13 revealed that nothing was shorting across any of the pins.

The 1040 card is the same between the 4020 & 6030. The 6030...

Rodney,

This last round of error messages have been displayed when the card cabinet is the same temperature as the ambient - ~80F. When cool air was blown on the cards this morning, the message...

Started the 4020 up with the same SCALE error.

1. Removed the 1010 x-axis card from the back plane and restarted with the following error message:
Emergency Stop - Take Appropriate Action
Scale...

The 1010 cards are all 1010-1. For all three cards, jumper J4, and eproms U19 & U26 were removed and reseated. The U19 eproms were all a V87.3H, and the U26 a V89.3. All the remaining cards were...

Yes, I have a 1991 6030 sitting right next to it.

I'll turn the 4020 on again first thing in the morning and measure both the DC circuit board and AC line voltage, and then do the same thing again...

Went out first thing this morning and it came up with no problems. Voltage readings were +12.15V, -12.17V & +5.06V.

Mid-afternoon it was started again with the following messages:...

There is nothing on top of the card cabinet, but is a rectangular box on top of the inverter / power cabinet with two wires running into it. There was no probe on the machine when it was purchased,...

Several years ago, an intermittent 'SCALE ERROR' would appear on the screen in lieu of the 'Enter CS' message. If the machine were turned off, and then turned on again, it would power on correctly....

There was no problem either downloading the archive or opening it with the XP64 native zip program. Some of the CamWork files required WinZip to open, of which there at used to be a freeware trial...

The inverter went out on the 4020 here, and a rebuilt unit was installed. Since the core charge return amount was small, the old inverter was kept and was taken apart at a later date to see if there...

Try removing the filter and see if the problem persists.

Had the same issue on the 4020 here when the extension tapping head was first used. It was fixed by entering SETP, scrolling to the RPM factor, and adjusting the RPM factor until the extension head...

Here is what I would do on the 4020 or 6030 here if noise were present:
1. Remove the X-axis radial bearing (opposite end of motor) and see if the noise persists.
2. Home the machine (HO), mark the...

Sounds like some of the memory connectors are corroded.

Try removing the cards from the back plane and cleaning with a pencil eraser. If there are any removable cards on the main cards, then...

Is the play in the carousel with respect to the arm?

On the 4020 here, an ATC error was generated when the spindle released the tool and retracted vertically. Turned out the two bolts holding the...

Check to see if there is any lube on the front or rear way.

If either way is just lube starved, you *might* get lucky by removing the way lube line from the side manifold and pumping it full of...

Sounds like the tool holders are sticking in the spindle - did the same on the 4020 here as well. Go through each tool in the ATC and polish off the end with scotch-brite to remove all the oils and...

Also check to ensure that the two bolts holding the tray plate to the main arm are secure. On the 4020 here, the spindle would fault out above the tool holder during a tool change. Turned out the two...

Suggestions:
- Reinitializing the memory.
- Remove and re-seat the memory expansion board several times to clean the contact pins.
- Clean the processor board back plane pins with a pencil eraser.
