Hi Scott,  That is correct. A standard stepper motor has 200 "Full Steps" per revolution. The Geckos do 10X microstepping. 200x10 = 2000.  TK From:...
Hello Tom, I uploaded some pictures about my setup. I also joined screen capture and My init file. I did some tests but I'm not having good results yet. Jerome...
I've wired up my drives (Step/Dir I/F to DC servos) for four axes, and my master enable (which controls my power relay), and configured KMotion and Mach3....
Hi Ray,  I forget what type of amplifiers you have.  But it sound like you have KFLOP Step/Dir configured for "open collector" mode where your amplifiers...
Hi Tom, About the error counter, feed forward, I tested it and also did without, I just took the picture with. I will reduce the acceleration, I tested the...
OK, next question - PWMs. I want to use PWM0 for my spindle speed control. Am I correct in interpreting the include file to say that each PWM has two...
(I think) I've written a C function, based on SpindleMach3PWM.c to control my spindle I/F using PWM0, but I'm not at all clear on how to "plumb" this into...
Hi Ray, Â There is a cell in the Mach3 | Config | Config Plugins | Dynomotion where you specify the C program that you wish to have handle the Mach3 Spindle...
Hey, I connected my linear encoder 1um (4um/sinus) to input 0.(gain 1 & offset 0)) And I connected my DAC driver to output 0 (gain 1 & offset -11) The DAC...
Hello, I think I resolved the problem. This was a security issue. I found that because the command and output signals were flat. To me it was like a...
Hi Frank,  The first thing to try is to increase the tachometer gain in the amplifier. Maybe your amplifier has a setting or potentiometer for this. This...
Hi Jerome,  That looks very impressive! A complete move of 10,000 counts (whatever that is) in about 100ms.  If you were to zoom in or plot the error is...
I'm getting really close to springing for a KFlop, but it's critical the switchover from Mach3/SmoothStepper be as quick and painless as possible, so I want to...
Wow! This is interesting! I posted this message about a month ago! Why is it just showing up here now?? And people wonder why Yahoo is having financial...
Tom, Thanks. I shoulda known that, since I did see it before.... Trouble is, there are so many places to look for various bits of configuration, I can't...
Brad, Huge help.That will get me a long way. I keep getting a 'KMotion_dotNet.DMException' but I think I can figure it out. Was this compiled in VS 2008?...
Hello, Yes, it was compiled in VS2008. If you can tell me when/where the exception is being thrown I will try to point you in the right direction. -Brad...
Hi Troy,  No. I assume you are referring to buffer delays with regard to changes to the feed rate override.  These were bug fixes with regard to the...
Ya, thats what i was referring to. O well, thanks for the info, and I still think that the KFLOP is the best thing since sliced bread. ;) Thanks again, Troy...
Hi Tom, Thanks but this is only possible because of your (huge) previous work. The resolution is 2000 counts/mm, one turn is 5mmm=> 10000 counts. I will update...
I have only the four axes connected to my machine at present, and it seems to work fine, except.... fairly often, when I jog, the axis will just take off and...
Hi Jerome, Â That book looks familiar and like a classic. Â Here is a link for one of the best books to explain the underlying math in a fairly readable...
Ya know, I find this behavior quite alarming, from a safety standpoint. Clearly, the KFlop is setting up a pulse generator on the axis, and just letting it...
Hi Ray,  Sounds like you have noise problems. KFLOP inputs are high impedance and fast.  Regarding the "runaway": It is probably noise causing the...
