Zeroing working but not moving off switch

[ahooper]

I have X++ X-- and Xhome as well as Y++ Y-- and Yhome switches set up as normally closed so that when one is pressed the input goes high.

I can auto zero the and the X and Y set the machine coordinates to 0 or whatever is set in the back off setting however rather than the X or Y moving off the button by the set distance it backs off just enough to reset the switch then stops and the machine coordinates get set to the distance in the backoff setting.

Originally i thought it was the denounce setting so i set this to 2000 but it had no effect. I have pretty much tried everything including creating a new profile but nothing seems to work.

I have even tried upgrading to the latest version to no avail.

Any help would be appreciated

That's how it's supposed to work. It just backs off enough to get off the switch.

If you want it to move to a position after homing, you 'll need to modify the homing script.

After the DoButton commands, you can add:

Code "G0 Xxx Yyy Zzz"

which will move it to where you want after it 's done homing. Just add the coordinates you want to go to.

Thanks Gerry, Will give that a go

I was sure that the earlier version I was working with backed off by the amount set in the "Back Off" setting under the homing settings.

I added the following to the button

Code "G0 X10 Y10"

This has been inserted after the DoButton's And I have tried inserting it after the DoOEMButton's but still no joy.

Can you post the code in your Ref All Home macro?

Also, are there any error messages?

[ger21]

Sorry, try it this way:

Code("G0 X10 Y10")

[ahooper]

The button i am using is the RefAllHome
I have inserted the code and have tried both below the DoButton(25) and below the DoOEMButton(135).

When the button is pressed the X and Y move out 10mm at jog speed then slowly seek the switch then back off a little way.

DoButton( 24 )
DoButton( 23 )
DoButton( 22 )
DoButton( 25 )

Code ("G0 X10 Y10")

DoOEMButton(133)
DoOEMButton(134)
DoOEMButton(135)

[ger21]

try:
DoButton( 24 )
DoButton( 23 )
DoButton( 22 )
DoButton( 25 )

Code ("G0 X10 Y10")
While ismoving()
Sleep 100
Wend

DoOEMButton(133)
DoOEMButton(134)
DoOEMButton(135)

I get the same thing, Router moves out to X10 Y10 and have tested with other distances to be sure that this line is what is doing it. then goes back to the limit switches and backs off a little.

I however think i may have figured out how to partly acheive what im after.

In Motor Home/SoftLimits set the Home Off to -10 for X and Y
then hit the RefAllHome button with no additional code or alterations.
This will set the machines coordinates to -10 and move to a point where it is just backed off a little from the limit switches. (i have reversed axis on my machine hence the need to set it to -10)
Then hit the Goto Zero and that will move the router to the 0 point and will be 10mm away from the switches

Bit of a long winded way to do things and will see if i can find the DoButton( xx ) for the Goto Zero then insert this in to the RefAllHome so its just a single click to get to the zero point.

Do you actually have encoders that your zeroing with the DoOEMButtons? What if you zero them before moving.

And setting the offsets negative is the proper way to do it, imo. That's what I do.

DoOemButton (1017) is GoToZero.

[ahooper]

Strange, I found that by adding the DoOEMButton(1017) to the end of the list the router would zip out to where the 0 was set to then it would set the machine zero by going to the limit switches.

I have decided that for now will use the RefAllHome and the -X and -Y to deal with it. Seems to work OK

Thank you for all your help and certinly if you think of anyting please let me know and will try it out.
