View Full Version : Indexer Stop Z safe?

I had a question when running the Indexer. If I'm zero'd out at the Center of the rotation and I hit the stop it moves the Z to a safe ht of 1.0
Which takes me down some 20" + / - ruining my part and / or hitting my center support bar if one is in place. Do I have to change my over all safe Z ht to something much higher (permanently)? Or can i change the safe Z in the toolpath itself so it only changes it for the Indexed toolpath being run?
Thanks

Not being able to visualize the part but if i understand correctly, if you have your Zzero set for the center of your material and it is at 4" thick and your safe Z is set at 1" then depending on what program you make the part with it should have a setting where you give it the diameter of the part and thus should know how high to lift the bit to make it 1" above the diameter of the part (being 2") for a total of 3" from the center. There should be a safe Z setting somewhere, but also on the control software on the lower left is a tab where you can set your safe Z.

This may have nothing to do with the program you created the part in however I have noticed that when i do a JH (not on the indexer) that rather then raising up to the safeZ height then moving it just moves and will drag across my material or right at the Zzero height as if it is ignoring the command to move the Z to the safe Z height.

I have since just doing a MX0, MY0 commands instead till i get it worked out. This may be what you are incurring.

Jack,

Check your custom99.sbc file - that's what is run when you hi "jh"

here is my custom99 file copied here. Do you see anything wrong with my settings? My "safeZ" is set at 1" on the control software.

'[JH] JOG HOME ... see notes in file regarding this example

Hi Jack,

Nope, that is exactly like mine - what version of the ShopBot software are you running?

v 3.5(?) I can't get the pgm to open without being connected to the bot. I get a "type mis-match" error message and it craps out. Next time i go out i'll hook the laptop up and get that. It is not the latest version i'm sure.
