[Emc-users] OT: one armed bandit's arm

Hi all mechanical engineers, I am looking for mechanical drawings of a rattling arm of a one-armed-bandit, aka slot machine. The arm of those old slot machines will make that distinguished rattle sound while being pulled and then, at the end, the mechanism will reset. The arm will only reset if

[Emc-users] Rookie Question - Direct wire or connectors

I suggest looking at the AMP CPC connector family. Relatively small size for the number of contacts, readily available including EBAY, gold contacts, tin contacts. I do caution against putting the motor leads in with the encoder and limit switch signals. Decades of pain and suffering is sure to

[Emc-users] End of year thanks!

I want to thank all of the developers & testers for their hard work on my favorite machine control system! I went over to the school this week to do updates on the Bridgeport, and get it ready for the new robotics competition season starting next weekend, and get some prototype parts made for the

[Emc-users] Looking Forward - Will there come a point where Path Pilot may be a GUI option?

I know as is it has been integrated into the OEM Tormach Mill and lathes it has many specific functions dedicated to that hardware. I just wondering that will a perhaps watered down generic version be available as an LCNC GUI. I have moved my second Hurco knee mill to my shop and once I have

[Emc-users] To Peter C Wallace

I tried to hook up my soft start circuit tonight, but when I had it wired in, the spindle didn't run. Checking dmesg, the card did not sign in like it usually does. Backed out of the mainboard socket at least 1/8", again. By bumping the parport cables molded connector against the wall. So I

On the 120v side if I measure from the hot to the ground I get 79 volts, if I measure from hot to neutral I get the expected 128v... what is that telling me? JT On 12/25/2015 4:51 PM, John Thornton wrote: > I think a fresh thread is in order for this ordeal. > > I'm starting at the plug... I

not sure what it is called but third hand brake tools for bicycles and some snap ring pliers have the same thing. Crimper's for terminals on avionics conectors use the same thing. there is a rack of slanted gear teeth with spring loaded dog in side like a sprage clutch. hope this gives you a

Hi Gene, I have used hot glue from a hot glue gun in the past (the Kind for arts and crafts) to hold cards in. It works well for high vibration and you can peal the glue off to get the card out if you need too. Not as good as a mechanical hold down but certainly better than nothing and not

Re: [Emc-users] To Peter C Wallace

On an aviation list I get many people use the glue E-6000 to pot electronics in. Not sure if wicking would be an issue, but no conduction or corrosion problems. It might bond a little better than hot glue, for better or worse. It will sag if put on thick and takes 24 hr to cure for most
