Rupert, You might want to try Neutrik.com. They have audio, video and data connectors of a lot of configurations. There are lots of studio suppliers here in...
Thanks Guys. I found a good supplier of electronic stuff in Edmonton. <http://www.ecl.ca/> Most of the stuff they sell is in the warehouse but they seem to...
... You should note that limit switches are usually "normally closed", so you can't run the machine with a broken wire. RCA connectors aren't locking, and...
I dont have much time, as im trying to make a decision before geckos sale ends. I am building a 4' x 3' plasma, Gantry weighs 50lbs, and I am using 3tpi...
... LOL... Post made it right about time for sale to end!! I went ahead and got the G201s, hope I made good decision! I think I did. If interested, I posted...
Hello Steve, The limit switches are wired in normally closed as you suggest so a broken wire or a disconnect should show up right away. One reason for choosing...
A quick heads up to all those who have G250's but haven't yet installed them. There is a dodgy (i.e. wrong) wiring diagram out there which will blow up your...
Dougal, Thanks for the information. We are currently testing three drives on a new board that Jim Cullins designed. I am very pleased with the performance. ...
Hello, If I am using a 48VDC power supply, is it OK to use 470uF 50V capacitors? I have these size on hand. I have on hand 1/8 watt resistors that are the...
A simple question, Will the current generated with "hand move" the motor, damage a connected (but turned off, off course) gecko, I plan to leave manual...
Hello, I have CandCNC B.O.B,and they say they dont use disable pin on drives. How can i disable drives with a manual switch,like a toggle switch? Thanks, Troy...
Hi Rey, If you spin the motors fast enough you can generate enough power to turn the Gecko on. Even assuming the Gecko gets reset, the worst it would do is...
i bought a stepper motor connected to bipolar driver, i want to control this stepper using unipolar driver and keep the old bipolar driver transformer. if i...
... few ... I put together a power feed for my small mill a few months ago using a stepper and driver board (the CNC version is still coming along). I found it...
I inherited a really nice X/Y/Z table from a local machine shop with gecko servo drives on it. They never bothered to wire up limit switches, so I'm adding...
You can wire limit switches are wired in series.
Normally closed switches are a good idea-that way when the loop is broken, either by a switch opening, or a...
I think a switch in the line is ok, as long as you make sure never to switch it while the motors are under power.

... convenient to mount one. Both ends of the other axes are recommended, though. If you are talking a BP type mill I wouldn't run it without limit switches on...
Sorry-my post came out garbled.
I meant that most will not mount a limit for Z-- (the lower limit on Z). I may be wrong about that, also. I know on my mill it...
... You may be able to mount a bar that sticks up "soemwhere", and put the low limit switch above the high limit switch (or use the same switch, if it's a cam...
Yes, that's true. But I don't really need it-I use steppers, and at the bottom of the travel of the Z axis, they just slip. Sure, I lose my reference, but I...
Thanks for your help, folks, I appreciate it. I'm using a G-Rex G100 for the controller and G320's for the drivers. As there's only one input called "limit"...
Kevin, I don't know what the G100 does with the limit input, but the typical response to a limit being hit is to shut down all axes immediately, by cutting...
The 340 is a servo drive. It is a a very bad idea to run servos without limits. You are setting your machine up for catastrophic major damage and possible risk...
