Aw, shucks! I got my geckos from Industrial Hobbies 'cause I needed the heat sink too so I don't have the pleasure of the little gecko :( John (Bloy) ... ...
Everything is shielded. By chance, we installed a 10 microfarad capacitor on the 5 volt power wire that powers up our encoder and "Bigo!" all is great in the ...
I had the same crosstalk issues when I retrofitted my Bridgeport. I was able to just seperate the motor leads and encoder cables to rectify. It seems there...
There are two vendors selling basic 6A stepper drivers on eBay. One has a website http://www.electronicutopia.com and is selling them for under $25. Seems to...
microstepping has NOTHING to do with accuracy. It is a way of eliminating low speed stepper resonance issues, and for me there is NO SUBSTITUTE for a ...
We tried the wire separation and isolation, we even swapped motors and encoders with the Y axis. We are at the mercy of the machine's construction. The Z axis...
I gave mine to my dog, he ate it, guess he likes geckos too! I wonder what will come out, after all it's sort of like the magnet found in the oil pan of a car?...
Could be the electrical interference from the VFD but have you try'd to tune the Servo? There should be 2 places to make adjustments to the Servos for proper...
We just went through this discussion on the emc-users group. The general consensus was that USB parallel ports will not work because data might be queued,...

Hi Dave Not wanting to appear to be rude, but "crap". The discussion on the emc-users group was all about routing the step and direction signals via USB to a ...
The original poster stated he was using TCNC, which only does step and direction signaling, as far as I know. (I've got 3 machines running with it.) I agree...

Wasn't Art Fenerty working on a system like this for Mach2? He referred to it as a "cube" or something like that? Basically a remote pulse generator. However,...
I'm trying to install a decent flat, stiff bed on my hexapod. I bought a 24" x 24" x 0.25" piece of steel plate from Metal Supermarkets, but it's not flat. In...
I have made a manual pulse generator with a serial port. This could be used to generate step pulses, and should be able to be connected via a USB<->serial...
Yeah, that is common with large plate. It happens at the mill and occurs in lower grades that werent rolled properly. Metal supermarkets buys alot of "shorts"...
While running the mill today and thinking about the runaway servo issue should an encoder fail. I wondered if an electronic device could be designed that...
Ron, Geckos won't stop in event of a lost encoder (Don't ask:{( As a matter of fact, there have been times that I was testing and wanted the servo to run for a...
I had assumed that the microsteps/half steps were for increased resolution. I stand corrected. The gecko microsteppers are about 5 times the price of these...

Al, This is a vast over simplification of the problem. If it were just that easy to set the feedrates above the resonance bands then there would be no need...
