More Noob Questions With XR and Sheetcam

CrossFire ® XR General Discussion
1

Have the XR setup and a few things seem off.

  1. Can’t move the cross head with the limits on. The limits always trip no matter where the head is located.

  2. The ‘Y’ seems backward. When I stand in front of the table looking down at it. Negative ‘X’ is toward me. Negative ‘Y’ is to the right. For most directional things, negative ‘Y’ is to the left. Is this correct?

  3. Sheetcam is giving negative numbers in the code lines. Trying a dry run is banging on the travel ends. Are those numbers absolute values or change from last position values?

  4. Sheetcam shows a red rectangle and a gray rectangle. Is the working space the red or the gray?

Were you able to run the break-in program for the XR?

Just curious to start before getting into all the other questions.

This will sound stupid.
I didn’t know there was a break-in program for the XR.
Where do I find that?

It doesn’t sound stupid. Not asking questions is stupid.

There is a couple links in the assembly guide for the XR.

here’s the direct link to the download page

It’s step number four of putting your XR together

Let us know if you can successfully complete the break-in program.

Ok, downloaded and tried to run the break-in program.
Does not complete.
The head runs from the near left corner all the way to the far right corner. Then it grinds against the limits until I stop the program. I’m assumming I shouldn’t let it keep grinding against the limit.

You’re going to have to check whether you’ve looked correctly ordered your motors and limit switches.

Double triple check.

Definitely don’t want to leave it grinding.

Ok, reset the zeros to the near left corner.
The break-in program runs now. Just moving corner to corner 6 times.

Talked to the maintenance guys that put it together. The limit switch kit is installed. But if I turn the limits to on and hit save, it instantly triggers a hard limit. Does not matter where the cross head is located, it instantly triggers a hard limit.

If this is the 4’x8’ XR they need to see if one of the limit switches is broken or if something is depressing it

There is a decal on the front of the table that shows x and y directions + and -
Sounds like you have x and y backwards

There is no limit switch on X- so if you run the torch all the way to the right it will hit the hard stop

That above should read X+

Does anyone know what the connector type is for the limit cable into the back of the XR box?
I think it is a GX12-4, but not certain.

You do realize that you have the luxury of having a phone number for support just because you have the XR machine. They should be able to get you that answer.
