General Mach Discussion / Re: How Do I Change MPG Jog Velocity

« on: December 27, 2009, 01:11:46 PM »

Thanks BillC for the tips, I will check those boxes later today. I am using CNC4PC's MPG2 Pendant. I have recalibrated the MPG a couple of times still no change of speed, I am sure I am missing some little check box or setting just a case of tunnel vision right now.

Thanks for the input. The MPG was working like a charm until the last engraving program I ran through the machine now when I jog with the MPG in Velocity mode it is about half the speed it was before (really have to spin the wheel fast to obtain the jog speed I had before) and the MPG dro is sitting at 12% (seems like a default always at 12% when Mach is booted up)  but it does not make any difference in speed on any value I enter in it. From what I read in Hood's reply the MPG dro is only for Step Velocity is that correct? Just trying to get my head wrapped around why it has slowed down and how to get it back to where it was before.

General Mach Discussion / How Do I Change MPG Jog Velocity

How do I change the jog velocity using a MPG? I see on the jog fly out there is a DRO for velocity but I do not see a button for changing the velocity, I have tried typing a different value into the MPG DRO but it does not make any difference.

Thanks for your input Rich it is all making sense now that I am past the tunnel vision state and I now see it is really a small issue of resolution and there is nothing that can be done about it, again many Thanks for your help.

Hi Jeff
Thanks for your tip, I have played with changing polarity on both step and direction but still have same result, I know the SS has no say in what the DRO's indicate, if I do not select the SS on start up of Mach3 and run a test program or jog I do not get the extra step so this is why I think there is some setting with the SS that is causing the extra step. If I change the steps setting in motor tuning to the 30000 area the extra step problem dissappears but that is way too many steps for my setup, I require 8000 steps to obtain the proper travel for my machine.

I guess Rich is right it is small and meaingless from a practical point of view but it was not there until I switched to the SS and this old dog is not used to seeing the extra .0001"

SmoothStepper USB / Gaining Steps with SmoothStepper

« on: September 19, 2009, 04:12:25 PM »

My SmoothStepper gains a step when changing direction ie when any axis is in motion (in a + direction on the DRO) and then changes direction towards the -direction the SmoothStepper will gain .0001" until the axis passes thru .0000 on the DRO and starts the -direction on the DRO and then it will loose the .0001" extra step until the axis changes direction towards the +direction which the axis  will gain a extra step of .0001" again until it passes thru .0000 on the DRO. A dial indicator on the machine table confirms the extra step. I can run Mach3 and the SmoothStepper without the stepper motors hooked up and get the same results on the DRO's also (jogging and running a test program).  If I run Mach3 without the SmoothStepper I do not get the extra step so I think I have narrowed it down to the SmoothStepper. I am using the latest driver and plugin from the Warp9 site with the latest version of Mach3.
If anyone has run into this before or knows of of a setting that I should be looking at I would greatly appreciate any help offered.

Will it be possible to get a copy of the latest version of this screen set, it is exactly what I am looking for to use with my touch screen setup
