Turned on my lathe yesterday and it started the boot-up then gave the  
error message, "NOT CONNECTED".  So far have not been able to  Get any  
help from the company.  Did reach Tim Geist who told me he no longer  
works for Teknatool.  Sent an email to their help desk but no reply.  
Called the tech support number  got an answering machine, no callback.

Anyone ever see this error before?

NO.. very scary... Seen "low power" or something when turning it off,
but never that one..
Could it be a bad connection in your remote switch?

Got curious and googled it.. Can't find a thing on this error, but
several posts complaining of low voltage and other errors and
Technitool replacing the main board..

Actually it was a power surge.  We had a sudden electrical storm  
Sunday night and by the time it started I was afraid to go out to the  
shop and check.  I have a "whole house" surge protector in the shop  
and in addition, the lathe was plugged into a surge protector.  And  
not turned on.  Big laugh.

  It also got the well pump, the security lights and the lawn  
sprinkler controller, two phones and two wall wart transformers.  Had  
the pump pulled and replaced today and not sure I want to know how  
much that cost.

When you first posted I figured it was a loose connection or bad  
position sensor, but now I have a different thought

The main board is probably fired. If the display was fired it would not  
be displaying this.

Tim has not been the Teknatool rep for about two years now, and the  
staff at the new location gets buried in calls. To the point where  
sometimes you get a call back from the NZ office (I have twice). But you  
will have to talk to them.

I suspect they will have you get the instructions from the Teknatool web  
site on how to extract the main board. What he was doing the last time I  
dealt with this (about a year ago) what they were doing was swapping  
working boards for  failed boards.

While I have never had a failure in mine, after dealing with the Clubs  
lathe, another clubs lathe and two members lathes, I got fairly familiar  
with failures and repairs.

BTW, in the instructions for my DVR-XP they recommended that you have  
the lathe plugged into a good surge arrestor. I not only do that, but I  
also have a whole-house system at the breaker panel. Since I went to  
multiple layer surge arrestors I have not lost a piece of equipment.  
Before that I lost something every winter (we get lots of winter-time  
outages). My worst was about like yours

IF your well went out it could of been a lighting strike miles away, hav'nt  
found a surge protector that will handle a lighting strike  I have had two  
houses hit by lighting, one it hit the front of the house and blew out a  
wall outlet in the back bedroom.  The second house it blew every modern  
electronic circuit in the house but did not hurt an old tube type B&W TV.  
strange stuff.

Found the strike location--a block and a half away.  Large pine about  
20 ft from electric line.

Finally got to talk to Michael Swerbensky who is the representative of  
Teknatool.  Very pleasant to talk to.  He sent me a step-by-step guide  
to removing the two circuit boards. They charge $75 to test them, and  
this goes toward repairing the board or replacing it (them) if  
necessary.  A new board costs $500.  Plan to tackle it tomorrow.

Actually they replaced the main board (weighs about 1-2 pounds), the  
front control boards and the speed sensor board.  He even wired my  
remote stop leads directly to the new board instead of the plug prongs  
like I had my old one, which were soldered to the connector prongs.  
Actually the charge was $561.16.  But it works again.  The stuff  
arrived Monday evening.

Update:  Mike called Thursday with bad and badder news.  Bad--the  
processor on the main board is "fried" and not repairable.  
Badder--The price for a new board is $561.16, not 500 like I was led  
to believe. Supposedly it is on the way.

No turning in July.  The withdrawals are on in force.
