I'm happy to say that after raising a little hell I worked with a senior tech, and while we both were dumbfounded that a new motherboard, carriage and data cable (which doesn't fit BTW - it'd for a smaller machine), we decided to try a new power supply and it works now. Even the fan works that never turned on in the 4 years I've had it. Thanks for the support everyone, glad I wasn't crazy... Well....

The USB port of a Surface dies not have the power to run a plotter on its own over 6'. I'm shocked it's working well even with a 6' cable. In practice, the USB specification limits the length of a cable between full speed devices to 5 meters (a little under 16 feet 5 inches). For a low speed device the limit is 3 meters (9 feet 10 inches). If 6' is working, I'd stick with that unless you buy a nice active cable, but only if you absolutely need more than 6. Also make sure your unit is grounded, like full grounded. That would be frame, stand, rollers and vinyl all grounded to a wall plate screw. Google it if you're not sure.

So here's deal, hopefully someone can assist me.... So I have a 50-something" LaserPoint 2 cutter using FlexiSIGN Pro 10.x About 3 weeks ago I was cutting some decals on some 15" vinyl. During the cut it got near the edge and started, well, we know what happens there. I immediately hit the reset, which of course started moving the carriage to the home position, catching the crumpled vinyl. I stopped it, pulled the bad vinyl out and reset up everything. Started the cut again and the carriage moved to position, but did not go up or down. After checking the forums, I did the 9v test and the electromagnet worked, no issues. Support was happy to sell me a new motherboard and ribbon cable. That didn't help. They were of course happy to sell me a new carriage. Of course that didn't help. Everything except he power supply was replaced, and it still doesn't work. A "support supervisor" said he would personally help get this figured out. That was 2 weeks ago and I have not heard back since. He claims they are reaching out to the manufacturer for wiring schematics as nothing else seems to resolve the issue. I did ground everything, to the wall, stand, and damn near the neighbors house. Volt meter shows no power from motherboard to the carriage along the Z-axis board, but the laser does work without any issues. I'm at a loss. Of course US Cutter just wants me to buy new equipment from them. That's not really an option, at least not from them. If I buy another one I'm going to either Graphtec or possibly a Roland. I'd like to get a printer / cutter (I know, I've heard it all), so if I'm replacing the unit I need to find a vendor that has one. At this time I can use my MH-721, but that's obviously limited in what it can do (although it does seem to do a better job than the LP2 at cutting). I would like to get this unit working, anyone have any ideas? Is it possible that it's the PSU? What would be the best way to test it? We did find a connection (on the PSU) that appears to be for the fan but nothing plugged into that one. I've asked for a diagram but they claim not to have one. I'll take any suggestions. I'm a support manager for an IT company during the day, and I'm pretty competent with electronics and can use a multimeter and soldering iron, so I'll try anything that makes sense.
