Jeff, I saw the I/O stuff. I just have to re-assign pin 8 to one of the available pins on the new board. I'm looking at 14,16 & 17 (out) or 1 (in/out). I've...
Jeff, I downloaded the datasheet... I get 0.0V between Vcc/Gnd... And, just like with Vbb/Gnd, when I measured Vcc/Gnd the red LED went off and you could hear...
Hi, I'm not sure what's going on with the measurments there. The red led on means at least a couple of volts. Measuring this voltage with the meature should...
Jeff, a question....When connected to the PC's on-board PP, a red light (just North of the IDC26's left side) lights during boot, and untill TurboCNC was...
Hi, The small amount of current from the PV parallel port can back- drive the circuitry on the drive board and light up the LED. The LED should come on full...
OK, it works. But I can't be sure why. All along I have not been powering up VBB. I didn't want to release any magic smoke 'till I had the bug worked out. I...
Hi, If you are using a 12V power supply for the drive baord, you will get mediocre performance from the drives/motors. You'll double your speed if you use a...
Ok.. Yet another saga in the trouble of setting up a CNC machine. I have a Xylotex board and three steppers, 4 wires, bipolar, 425 oz in. It's the 'kit' they...
Jeff, as an aside, I got things all hooked-up last night. Set my Vref's, wired-up the motors, fired-up TCNC and....Y works fine, X sounded stalled. No motion,...
... Not to be mean: but it is very obvious that you have read none of the Mach 3 documentation, watched any of the videos, nor have you spent much time...
... Generally speaking Michael, if you are going to be running that close to the "broken mirror" point with an adjustable power supply, please bear in mind...
Gene, thanks for all of the great info. The PS I use with the Xylotex is a 0-60V/5A Protek bench supply ( http://www.accuratepower.com/Torch/Computer.jpg ). It...
Ok.. I'm starting to get a little offended here. Every time I ask a question in this forum, I'm faced with somebody who replies as if I'm a complete moron....
What speed are you considering 'LOW' , and what are your settings for the acceleration? Before upgrading to better lead screws, I was able to get rapids of ...
... As I said before I was not trying to be mean, nor do I suspect that you are a moron, your just very ignorant of the subject matter (as we all were to start...
I am going throw a little humor in here based on the subject line... Seems like the motors aren't the only think being jerky or whining around here! :-) Oh,...
Do you have a signal generator? If so, try driving the STEP input on the Xylotex from the signal generator, and ramp the speed from very slow up to the...
... This is one of those things that if I had to guess, I'd say the computer is using an onboard, shared memory video chip setup. Common on laptops. Becoming...
... That is part of it Mike, the limited src and sink currents from such ports also play heck with the noise margins. ... -- Cheers, Gene "There are four boxes...
Has anyone in wnc done a cnc router and would like to show a prospective builder their finished product? I would love to see one in action and learn some...
Hi, The was a yellow pice of paper attached to the drive board. It explains how to set the Vref. Vref = amps X .8 2.0 = 2.5 X .8 fro abs max setting of...
So... I have a new desktop computer. In Mach 3's driver test, I get a smooth line. I hook it up to a Xylotex 3 axis board.. and the same thing. Motors just...
Hi, Most likely you need to set up the parameters correctly. Incorrect parameter setting in software will make ANY system function improperly. You need to make...
I've tried everything. I have all the pins and ports set correctly. I've adjusted the Velocity and such every way I can think of. I can, AT BEST, get the...
