i do not know. Our TM table is 5x10 so haven't had to deal with that. however if you are on Facebook you should join the group CNC plasma tips, tricks, and sharing. Lots of guys on there. Also look up Gamble here on plasma spider. he has a 2x4 TM table

Here's a video for indexing on an Arclight. You may be able to transfer that info to your Torchmate.

Hope it helps.

I've done it on my old Torchmate 2x2 and 2x4. First you're going to need to divide your drawing in half, and then set it up to where you are cutting both parts at 0,0.

Then you're going to need a fence. I welded a piece of 16ga to my slats, and then ripped it with a simple line program down the Y axis. Having the fence allowed me to stay exactly on the Y0 axis..

Now the tricky part. Lets say for example you're trying to make a 48" overall piece. You're going to need to shift your sheet a full 24" exactly, then load your other half of your program. For simple stuff being totally exact wont be super critical, but for stuff with critical hole alignment, or for a large art scene, being off just a little can be a deal breaker.

I suggest picking up one of these:

viewtopic.php?t=22275

I knocked my xbox controller off it's bracket yesterday and reset my y axis when it hit the ground, with 1/2 a job cut (and the perimeter of a part 1/2 cut). Using this, I was able to line up exactly on a 90 degree cut (partial cut of the perimeter, so a kerf-width line), by placing this pointer exactly in the middle of the kerf in both directions (by eye). I then looked on Sheetcam to see what the coordinates of that point (the 90 degree corner) should be. Entered them into my x/y position, tested the location a time or two, and let 'er fly. Couldn't even tell where the repositioned cut blended into the existing kerf. I was quite impressed, and pleased.

I think indexing would work exactly the same way.

Edit: I don't have a Torchmate. I use Sheetcam and Mach. Same mechanism should apply, though.
