    This may seem like an obvious suggestion, but unless your common mode voltage is something crazy why not just buffer each side of the differential signal separately?

    A schematic would really help...

    Getting work through your current employer is a bit of a crap shoot: if you have the same basic type of equipment as your current employer (3 axis 40x20 mill, for example) why would they pay you to...

    Because customers want the lights to turn on automatically with remote start, turn off automatically and not run the battery down.

    Maybe you want a user interface that looks like the cockpit of...

    If you find a seller with one box of obscure inserts from time to time they're probably real (and stolen from work.) If you find a seller that's sold hundreds of the same boxes of inserts for half...

    Are you a good engineer? Do the skills, training and experience you've accumulated as an engineer translate to running your dad's shop?

    Cut it slightly long, measure the angle, then adjust and make your final cut?

    You'd mill a master, and lay up (one or more molds) off of that.

    I'd be curious to know why you feel the costs would be better for the 3d printer. The gantry on this would cost the same as the...

    I'm fairly certain that the boat they printed was nowhere near 100 feet long, it looked more like twenty. How long does it take to lay up a 20 foot fiberglass hull? I'd be shocked if it was more than...

    Doesn't have to be if one is willing to work a little more nitty gritty.

    A Halcon runtime license is a grand or two depending on what modules you use. Matrox is half that. Then a point grey...

    If it's a big window such that the drop is worth keeping and meaningful volume, a vacuum fixture will keep it in place nicely. You'd still want to onion skin it and then do the final cut-out towards...

    I had some machines that absolutely required 230V 3 phase, so in my old building with 208 from the street we had to build a whole 230V supply with buck-boosts.

    Now everything gets fed from the...

    Have you ever seen a dealer claim that a machine was poorly maintained? Even in the face of objective evidence?

    37k USD sounds awfully high, especially for an orphaned control. Maybe 25k.

    Yeah the price for the spindle is basically highway robbery. One of my guys broke off a pull stud once and the spindle taper and tool holder were playing ID grinder while he froze up, so I didn't...

    Routers don't have a lot of torque and don't have the rigidity to do steel. They rapid faster than a gantry (3000ipm isn't unusual) and they're designed for vacuum part holding with very big vacuum...

    There's no real reason to buy a vacuum plate, they're easy to make, but if you do, there's a guy on Ebay who sells pretty decent ones for very little money.

    I get a lot of use out of the one I...

    It's a little different than C on a lathe or a mill: you put a right angle tool on it and the C swings it around to different positions while still driving with the spindle. It's so you can saw or...

    This probably isn't the right place to post this, but I have to vent somewhere. I went to look at a fairly recent used machine, a Thermwood CS45 5x10 CNC router with C axis. 4 years old. Nice...

    Because literally every post you have ever made on this site is trying to sell something. I get it, that's your job. But this isn't that kind of street corner. Go hustle somewhere else.

    Sometimes the owner is running through one broker, it doesn't sell, then they list it with someone else. Ebay is often a secondary/advertising channel for these guys. Not expecting to sell there,...
