Allow me to play Devil's advocate ;> (and just think aloud) Heat generation is an (I^2)*R problem. 'V' (or 'E' as I was taught) is just the 'pressure' used to...
Jack, Mach's parallel port drive is the limitation on pulsing speed. In reality everything in your machine has to work together. For instance, a high...
Jeff, Please try this experiment: Chuck a step motor up in a drill press. Make sure the the motor leads aren't touching each other. Set the drill press to a...
Yes, you are 100% correct but it is still an (I^2)*R effect, current flowing through a resistance creates heat. What I was getting at is that by your ...
I somehow must have gotten a reputation of being 'prickly'; I'm not really.:-) So where does this heat come from? The easiest explanation is RPM times detent...
I am curious, how much of the loss is hysteresis vs. Eddy current loss? Is there loss in the permanent magnet rotor? As it moves through each detent it too...
That would be hard to separate out so I haven't tried. Both are lumped together under the name of "iron losses". Measuring rotor losses would be very hard as...
I'm looking for a good supplier of timing belts, motors with the belt pulley already installed and also belt pulleys. Any suggestions would be greatly ...
With a conventional system and a high voltage at slow speeds you end up with very narrow PWM pulses to the motor. There are theories kicking around that this...
... from my personnal experience,there is not much price difference between sdp-si and the other ebay stores. advantage with sdp-si,you get all under one...
Got a new set of G203Vs. I have been using them for a few days, getting mach3 setup with everything on the bench (cotroller w mach3,control box w BOB and...

Hi d1, I just went through the same ordeal. For some reason or other my 'Y' axis motor tuning was corrupted. Instead of the usual 10000 steps / inch, the...
I have 3 G320's, 3 Keling KL34-180-90 motors, power supply and all the rest setup, and a step generator I bought from HubbleCNC on eBay. What I don't know how...
... Hi thanks, for the reply. I tested the G203V **without** being connected to the controller. In fact completely removed from the controller, motors and...
Hi Thos, The proper setting will be related to how much inertia and stiction your machine will have. With no load on the motors they can change speed very...
First off, I'm a total noob and this is my first post. Hi all! I'm running through the G320 setup procedure, and I'm at the point where I hook up my meter to...
Hi, You may have a bad 203V. I believe the 203V is the most bullet proof driver Gecko makes, so would get in touch with the tech guys at Gecko's web site and...
I think you have the motor leads reversed or the encoder leads reversed which will confuse the heck out of the motor. I also think you need to get the step...
hello I am trying to get the fault light out on a new install g540. I have been reading the archives, and found that there should be a check mark by the charge...
Hi M,  Encoders are most often labeled by the number of lines on the encoder wheel, so yours being 1000 would likley yield 4000 pulses/revolution. But...
The easiest way to do a new G540 install is to go the Gecko G540 web page and download the XML profile. Put this in your Mach directory and use it. Also be...
Ok! Call off the dogs. My problem was I did not have the 5v neutral for my external encoder power supply attached to Term. 6 (Enc -) on the Gecko. So with...
