Thank you very much for your speedy responses.  I will give it a look tomorrow and see if I can get anywhere with your settings.

OK just had a look, dont see any limit switches on them in the pics, are there limit switches on your machine?

Hmmmmm... ok well switches it does not have. I thought the limits were determined by the number of revolutions or something on the step motors (again I'm not as well informed about this as I should have been prior to purchase).  Here is my xml. file for the machine.

General Mach Discussion / So n00b it hurts! Help please...

Hello all, first post.  I am a n00b to the cnc world.  I have a sign company and have been doing it for 10 years. I have a regular vinyl plotter and also a full color digital printer/cutter.  I have recently got into building audio electronics and decided that a cnc machine might help out with some of my projects/business.  I purchased a cnc sidwinder 24" x 36" router and was told to download the mach3 demo.  I have no idea what I'm doing other than what the guy gave me as far as instructions and set up (which was minimal at best).   At first he did not send all the information so I was stuck unable to get the thing to even move for a few weeks.  Now I am able to get it running and use my hot keys to move the carriage around. 

Now for the problems I have...

1.  I set up the soft limits that he gave me and it doesn't seem to adhere to them.   Meaning it bashes into itself at the end of the travel.  :-\   (Attached what I was given)

2.  So when I set the zero position just before cutting and I move it and press return to zero it does nothing at all.  Won't return to where we called zero.  How do you set zero properly, I might just be doing it wrong?

3. I am able to make the  X Y  to move properly but with Z it will only go up and not down with the hot keys. 


I had my friend who runs cnc machines for a company that builds airplane and helicopter simulators over to see if he could help and he was stumped as to why the thing would not return to home or have soft limits.  Unfortunatly he is not familiar with the mach3 software so he has limited knowledge of the program.  Help from the forum is most appreciated and welcome.
