Re: Using G28

guys: do not confuse "knowing how to program" and "knowing how to operate" as mutually inclusive. while I have the better part of 1000 different machine configurations running around in my head (many long dead and sitting in the scrap yard), I NEVER touch a keyboard of a machine ...

Re: Using G28

Glad you got going.

Not sure what you mean by REAL CNC..but fully appreciate the differences between machine logic ladders.


Compared to what some of us started on with only G1 G2 G3 everything today is nothing short of black magic and witchcraft.

Re: Compressor woes

Then you get into 'is it a leak or the shot blast booth running with is essentially a FULL OPEN LINE anyway"?

I have the ultimate micro-controller...my brain and a push button.

sometimes the simplest solution is the easiest...and with my brain involved...SIMPLE is the key word. giggle

Re: Using G28

I have never been contacted by Dave C and honestly, since every control / machine lash up can be different and use G28 differently, I would prefer to have an un-interrupted conversation with the person about one machine configuration since it may very well only apply to HIS MACHINE and is best not c...

Re: Compressor woes

Adding the aux contact is not a good idea with the real world possibilities that exist around our farm: Your idea means that if the compressor is running it will automagically reset the timer and continue to run forever, which is not what you want....if you have a leak and have walked away, the comp...
