I put in G92z1 and moves down

Using the G92 and asking for negative and positive .5 it moves in both directions

I tried homing the machine the z axis still run down towards the waste board I went in and changed the wizard to home in the opposite direction and it reacted in the same manner! and as noted above I used G0z+ and G0z- and it ran in both direction that I asked for .5!!!

G92 is not a movement command. "G92Z1" would set the current work coordinates position to be Z1.0, without moving the axis.

"M92Z1" would be an error.

"M92/Z L1" would be a request to move in the plus direction, to the home switch.

If jogging Z+ causes Z to move up, but running "M92/Z L1" causes Z to immediately move down, then you need to look at the state of your home switch on INP1.

There is a "PLC Diagnostic" display that appears when you press Alt-i.

On that PLC Diagnostic display there are rows of red and green dots, showing you what is happening in the PLC logic.

The first (top) row of red and green dots on the Alt-i display represent the PLC inputs. The inputs on your Acorn board are INP1 through INP8.

You appear to have your home switch connected to INP1 (or at least, that is what you told the Acorn Wizard).

The first dot on the first row of the Alt-i display represents INP1. If the circuit to INP1 is closed, then the dot will be green. If the circuit to INP1 is open, then the dot will be red.

Your home switch(es) must be normally-closed. INP1 must be green when no home switch is tripped.

On your machine, when no home switch is tripped, is INP1 red, or is it green?

well when I use those commands it moved in the direction I wanted I went in and changed the wizard new pdf will be attached along with a report after changing everything it still wont work correctly!!!
I would like to mention that another newbie had post more eloquently than I have stated in my posts about how fed up he was with the product and all the wrong advice that often times contradicted one poster to another and finally threw in the towel and went with another controller!!! I don't have the luxury of tossing the in the can or I would and I am actually kicking myself in the butt for choosing this one but I have too much time and money tied up in this to give up and maybe just a little more stubborn

It's probably something you did wrong and these folks are trying to help you find it. Getting angry with them won't help your cause. When someone says they did everything perfect and it won't work, they are usually wrong.

Not angry but it doesn’t help when there are 2,3,4 people giving advice and they are not all on the same page, as an example I had been using the GoZ to get the z axis to moved and it worked and has been working! And was given them by a well versed operator! And I mentioned the other post be a different person threw in the towel I’m not!!!

In the last three reports, I only see one proper usage of M92/Z L1 (looks like the most recent one). What happens if you move the machine out into the work area and Z down a bit to be sure your off the switch and then in MDI, issue M26 /X/Y/Z. At that point, you should be homed manually at that location. Then try the M92/Z L1, what direction is it traveling? Should be up if configured properly. If it does go up and stops at the switch, in order for the Z machine coordinates to be set to 0, a M26 /Z is needed. If it goes down, something is not set properly somewhere.

Another command that could be tried, is M72 (Homes the Z axis with auto squaring). This is done in the direction setting that the wizard is set to (M91 or M92).

I also just saw in your last wizard screenshots, that the axis drive type values are not the same values that are set in axis config. Steps/rev don't match, did you actually hit the "Load Drive" button and then write the settings after configuring the rest? You have axis pairing enabled, but no Slave Axis Switch is set, but the input is supposed to be #2 according to the axis drive type settings, which also leads me to believe that you didn't actually hit the "Load Drive" button. You have the wrong screen size to run CNC12 optimally, and that can cause some elements in the wizard to be off the bottom of the page, and one doesn't easily notice that you have to scroll down.

Might be some missing parts to your puzzle.

Nothing I have tried is working with this controller as I mention if you read the whole post I walked away from this machine for a couple of weeks, After someone else wanted to set it their way and not how I wanted it set up I threw my hands up in the air other people with the same machine with Chinese controllers have been up and running for months where I have spent months just trying to get this controller to work, Bad thing is I don't have the money to throw this one away!!!!!!! I have changed settings nothing changes redid the changes that didn't work! Maybe I should post a photo and someone can look at it and that will fix it (sarcasm)!!! I have tried everything even some of the bad advice! I even just tried the advice Scot gave and it dam near drove the spindle threw the table before I could hit the ESTOP! I have been trying since March, April to get this card to work.
