LOL: a few thousand posts back our man posted a data sheet with a clear as day picture of the switch terminal layout. Just look at which freakin' terminal the wire's connected to and compare it to the pic.

Come on, that makes it far too simple.

Yes indeed 1mm / unit is indeed slow but it looks like that's what your post-processor decided upon.

I didn't notice a G28.1 in your code.

The default feed-rate is 6 units per so if you have not defined a feed-rate and call G28.1 I believe it will operate a 6 units per.

I think you answered your own question F1 is the feed-rate (1 unit per).

Oh, I already have small caps on the stop and limit switches now, can't remember the size though.

They need to be 0.1uF

Perhaps try an engraving point (bit) at about 30deg. angle for your serial numbers. You may have to use multi-pass at increasing depths (dependent on the total depth you need).

just one more thing: my pins should be set to active high.....by doing this will I cause any "magic smoke" lol to come out of my electronics?

Because I can't see the switches being normally open, that would defeat the purpose wouldn't it? meaning they would SUPPLY power to the axis when triggered instead of cutting power to the axis......

According to your .xml your switch input pins are set to Active High.

Maybe a good idea to connect a multimeter (set to ohms) across each switch to see if they are N.O. or N.C.  ?

I am pleased you have it sorted.

Hi Mike,

You say your switches are wired in parallel and your .xml shows the switches (including EStop) configured as active High. This being the case your switches will be connected as normally open (N.O.) – check your EStop switch to make sure it is open circuit in the run position (they are normally closed circuit in the run position) otherwise it will not work with this configuration (which may explain why it has not been working and no port# had been allocated to it).

The only other things, beside .set and .xml, to back-up (if you use them) are Macro's and Brains. Personally, I make a complete copy of the Mach3 folder (just in case).

Hi Mike,

Looking at your .xml file I notice that you do not have limit switches enabled – only home switches are enabled.
There is also a conflict (not serious but it should be avoided if possible) where X Home and EStop share the same LPT pin number 10. You also need to assign a port# to EStop.

Just to draw your attention to the relevant section of the manual…
• If you implemented configuration two from Section 4.5, you will probably have Home switches on the X, Y, and Z axes. Enable the Home switches boxes for these axes, and define the Port/Pin to which each is connected. If you are combining limits and the Home switch as one signal, then you should enable Limit --, Limit ++, and Home for each axis and allocate the same pin to Home, Limit --, and Limit ++.
