My home switches for the Y Axis are all the way back, my X Axis if you are looking at the machine are all the way to the left and my Z Axis tool is all the way up.

When I make a move (for example) if I move the Z Axis using the Page Up the tool counts in a - direction and the tool goes up. Page Down it counts up and the tool moves down.

The Y Axis using the Up Arrow the Y Axis moves towards you and counts - and Down Arrow moves away and counts +.

X Axis Right Arrow counts - and moves left and Left Arrow counts + moves Right.

I am using the Mach 3 Software, computer is using Windows XP and my CNC is a stationary table.

Can anyone tell me if this is correct or not? If not, could someone please guide me on how to fix this.

I am trying to do a test run with no tool of the Road Runner and when I try to do that from the home position the machine starts grinding while trying to move in the wrong directions.

When I tried making a Roadrunner after I move all my Axis to the middle of my table and I Zero them out and run it, it will then cut the Roadrunner.

What am I doing wrong and why will it not work from the home position?

Any and all help is greatly appreciated.

When I make a move (for example) if I move the Z Axis using the Page Up the tool counts in a - direction and the tool goes up. Page Down it counts up and the tool moves down.

The only way I can see this happening, is if you reversed the functions of your PageUp/PageDown keys, AND the motor is spinning the wrong way.

Can you post your .xml file so I can see how you have it setup? You'll need to zip it to post it here.

Do you want to see pictures of the screen or what is it that you are looking for?

[ger21]

In your MAch3 folder is a file with the same name as your Mach3 profile, PROFILENAME.xml

this file has all your settings. Can you upload it here?

[ger21]

Pictures and drawings wouldn't hurt, either.

Here some pictures











Here is the compressed file (hope it works)

If you or anyone else needs more pictures or info please let me know.

Did the zip work for you Ger21? I am not sure myself if it worked.

Yes. As I suspected, you're jogging keys are set up backwards. Use Config > Hotkeys to assign the correct keys.

In your last picture, assuming left to right is the X axis, the home switch should be on the left side. X+ should be to the right, and Y+ should be away from you.

Based on the 2nd to last picture, which has a better view of the 2 of the home switches I am using. the Z axis home switch is at the very top of the picture. The X axis is just above the motor on the left side brace. It is at the Y axis home in this picture. My table is approximently 42" long. Is this correct or do I need to change my home switches around?

Just so I understand the hotkeys. The right arrow on my keyboard should move the X axis to the right based on the 2nd to last picture. The left arrow would move it to the left. The up arrow on the keyboard should put the Y axis to where it is in the picture now at the end of the table. The down arrow should move it the length of the table (the whole 42"). Page up should move Z axis up and page down should move it down. If this is not correct could you please tell me the correct way of setting up my hotkeys and home switches.

Thank you in advance for all your help.

I choose the 2nd to the last picture to help me understand things better.

OK, so your X is the short axis, on the gantry.

If you normally stand where you took the pictures from, then I'd say that Y0 should be at the other end. You can still home it where it's at, though. What I would do is go to Config >Homing/Limits and put 40 or 42 (a little less than the actual travel) in the "Home Off" column. This will set the Y axis to 42 instead of 0 when homing. Or, you can put the home switch at the other end.

Then the keys are as you said.

[Eddieman]

Is the X axis home switch in the right spot or does it need to be moved to the other side?

[ger21]

It should be good.
