Hi all...

I recently picked up a 7x10 mini lathe (HF's 33684) that needs a
control board. HF wants $61 for a replacement, but armed with a
schematic, I may be able to troubleshoot and repair this one. There's
no visual clues to the problem (burned compunents, bad solder joints,
etc.) and quite a bit of SMD technology that's beyond my capabilities,
but I'd like to give it a try anyways! If you have such a schematic
and are willing to share it, please let me know here, or e-mail me at
mister.bill(at)starband.net I already have the wiring diagram that is
in the manual, but the board is represented by a white rectangle. I
need the schematic of the board itself!


Many thanks!

Take a look over on the 7x groups over at groups.yahoo.com. There's
been several iterations of the controller, some schematics have been
traced out and are available on their archives. It's usually the power
MOSFETs that pop, these are easily and cheaply replaced. Another
source for 7x related items is www.littlemachineshop.com. These guys
have all the parts available for the mini-lathe and mini-mill.

There are 7X10 board schematics and mods in the dropbox- don't have the
specific link.

Whats it called? I mean the file in the dropbox? I've looked back to
2002 for 2HP, treadmill, schematic, motor, control, and circuit. And
was unable to find anything about the 2HP treadmill board.

Never Mind, The file is in the 1998 dropbox files. I had no idea that
I'd had that motor that long. It's about time I used it. And, the mods
had already been done by me. Probably back when I first got it in '98.

I started to say it was a lot longer than 3 years ago when I still
had the time to trace a board like that.
