From the Mach Support page (www.machsupport.com) under  "Support" ==> "Documentation"  there is a pdf document for a Charge Pump Safety Circuit.

Is that what you were looking for?

General Mach Discussion / Re: Loading the Gecko G540 XML file

« on: June 01, 2009, 08:55:42 PM »

I have a slightly different problem.

After loading the Mach 3 software (and before loading the Gecko XML), I started configuring my own profile following instructions in the tutorial videos and information from my machine supplier.  Later in the process, I remembered the Gecko XML.  When I loaded it and started Mach 3, I got errors relating to limit and home switches.  Evidently the Gecko XML assumes that you have limit and home switches (which I don't yet).

What I'm wondering now is whether to continue with my own configuration, or change to the default Gecko XML configuraton and start over.  It would be easier to continue my own configuration, but, I wonder if there may be something "deep in the bowels" of the Gecko configuration that I need that I may miss in the configuration of my own profile.  I tried to find a (free) XML compare utility to examine the differences between my profile and the Gecko XML.  Unfortunately, the couple that I did find and downloaded didn't work.

Any thoughts from the experts?

Thanks for the manual reference Chip!  I read through that llong before I actually got the software up and running.  I guess it didn't mean anything to me at the time and I didn't remember it when I needed it.

I honestly try to answer my own questions before I come on here and ask.  Guess I just had a senior moment on this one

Thanks Ray! That's the answer I was looking for 

One more question.  You say "most modern PC's will handle 45kHz pulse rate". How do I know what MY PC will handle?  Will I just get bad results from the driver test if I try to go too high?

Thanks for the quick response Chip!

However, your answer still leaves me with questions. 

My steps/unit is (are?) 40,000, if I calculated it correctly. (200 motor steps/rev X 10 driver micro-steps/step X 20 TPI Lead Screw).

Your could just tell me if 25,000 is still a good setting for Pulse Frequency, or what setting I should use.

However,  instead of just telling me what value to use, I'd rather get more insight into exactly how the Pulse Frequency setting relates to the overall configuration of Mach 3. That way I can understand the implications of this setting and answer my own question.

General Mach Discussion / Pulse Frequency

I've just completed the video tutloriials, so I'm really new here.

I'm curious about the Pulse Frequency setting in Mach 3.  All the tutorial said was that you should set it at 25,000.  Why are there higher values?  When would you want to increase this setting?

I'm one of those people that just can't settle for "just do this" without knowing the why.

Thanks!
