General Mach Discussion / Mach 3 random EMO after installing new motor and VFD.

« on: April 23, 2020, 12:43:42 AM »

Hi all,  Can anyone tell me how Mach 3 generates an EMO signal?  My mill has been running for years but I just upgraded the motor and now it just randomly goes into alarm for EMO.  The EMO is not pushed.  If I knew what would cause an EMO signal (other than the real EMO pushed) it would help me.  Is it possible I have a noise issue after installing the 3ph motor and VFD.  Note that other than sharing mains AC power the VFD and cnc controller are isolated from each other, nothing is integrated yet. 

Thanks in advance for any input

General Mach Discussion / Feed Hold stopped working.

« on: January 30, 2016, 11:52:17 AM »

Hi all,  the feed hold (and space bar) stopped working.  Keyboard, mouse, pendant and touchscreen are all USB and I've been having fits with USB failing for the pendant but start, stop etc all work but feed hold does nothing.  Any ideas how to resolve this. 
I'm running Mach3 R3.043.066 with windows XP

Thanks for reading.

General Mach Discussion / Kernel speed error on startup

« on: March 11, 2014, 02:30:34 PM »

I was setting my steps per inch and inadvertently missed a decimal when I saved.   I finally figured out how to get it back to functional but now I get an error on startup "one of the motors is too fast for 2500 kernel speed".  It works fine and motor is noticeably quieter.   Any ideas where to look for this setting or why the motor is so smooth now?

General Mach Discussion / Mdi question

« on: March 07, 2014, 02:03:05 PM »

Hi all,   quick question.   When I input say,  X2 F10 I was expecting to move 2 in X at a feed of 10.  I get the email expected 2 in X but feed rate does not change.   What am I doing wrong?

General Mach Discussion / Mach3 with a DeskCNC controller?

« on: September 19, 2010, 07:40:05 PM »

Sounds like a few years back using Mach3 with DeskCNC controller was being worked on.  I have DeskCNC and it works ok but if I get suck, that's it, no help......anywhere, especially IMService.  I am considering just building a new controller but thought I would check one last time.  I saw a co. that sells a USB to LPT converter, will that work?
