Ahh I see, I guess I should have done some more research. But I only bought one to test.  Do you have any suggestions on where to but good dc servos and drivers?

Thanks again,
Tom

Thanks Hood I seem to have it working, I made your changes and a few other that I don't quite remember but it seem to be working now.

I have another question for you if you don't mind.  I thought that servos were a lot more powerful then stepper motors, I am currently test the servo on my rotary axis on my router, I have it tuned as per Gecko, but as the rotary in turning I can grab it and make it stop.  It seems no more powerful then my stepper motor.  The servo that I am using is from Keling  KL34-180-90 Nema 34 and a Gecko 320X driver.

Was I wrong in my thinking or is there something that I can do to get more torque from the servo?

Thanks,
Tom

 I forgot to mention that it all works fine when I am using the stepper motor.

Thanks Hood, I checked the pins and even changed the hot keys but still the same thing.  I forgot to mention that I am using a Smooth Stepper, is there a setting that needs to be set? I am using a C-10 BOB could that cause an issue?

Thanks,
Tom

I have just started messing around with a servo drive. I am using a Gecko 320X driver, a US digital 500 Line count encoder and a servo from Keling. In testing the servo I can control it from the MDI ok but when I am jogging it, I will work one direction ok but the other direction is hit or miss, and when I do get it to go the other direction it will only go once the I have to the reverse direction a few times then it will allow me to reverse again.

  I think it is in my setting in Mach because the Dro will not move if the motor is not moving.  I hope this is not to confusing the way I have described it.  Does anyone have any idea to point me in the right direction.

Thanks,
Tom

General Mach Discussion / Re: Mach e-stops on Program Load

« on: December 09, 2010, 03:15:00 PM »

Thanks for the help. It seems that as long as I have the toolpath view unselected when I load or redrawing, the e-stop won't be triggered. If I have it enabled then the e-stop is triggered. Does anyone know if in Mach 4 if this will be fixed?

Thanks,

General Mach Discussion / Mach e-stops on Program Load

« on: December 09, 2010, 12:11:21 PM »

I am have an issue with mach going into e-stop when I load a long program. I am using the current development version with the machstd screen set. I am also using a smooth stepper. It only seems to happen on the long programs.  Is there something that I should look for that could be triggering the e-stop?

Thanks,
Tom

General Mach Discussion / Re: Y axis toolpath display is inverted

« on: November 20, 2010, 12:09:52 PM »

Thanks for the input.  My router is a home built gantry router. I have another commercial Thermwood Gantry Router that the Home position is in the upper right corner and when you move away from home in the X or Y axis is is a Positive move and when you move toward home it is a negative move. I was trying to have it work the same way. I will just have to work with it the way it is.

Thanks Again

Thanks Hood but that did not work.  Let me ask this.  On your machine if you have a part 0,0 set to the center of your work piece and you move the Y axis so that the toolpath window is moving down, is that a negative or a positive y Move on your Machine? On my machine it is a negative which is wrong, but the DRO is showing as if it is moving in a Positive Direction which is correct.

I have tried changing the settings but if I get it to look correct on the screen the Dro is going the other direction.  Is there a way to have the toolpath display Y axis flipped 180 degrees?

Thanks,
Tom
