G83 Mystery

« on: February 19, 2006, 01:49:04 PM »

I have the following code, which I'm entering manually to test:

G97 S1500
G95 F.008
G00 X0 Z0
G83 Z-2.2 Q.2

If the spindle is off, the G83 works fine. If the spindle is on, the Z axis starts moving positive until I have to Stop it; I'm not sure where it's trying to go.

What am I misunderstanding? Thanks.

Sounds like you have THC turned on in the config, or in the config/ports&Pins/Mill options you may have "Allow Z up down cxontrols when not in THC". If so, turn that off. Was that the trouble.. ?

I should have mentioned that this is Mach3 Turn. Does this have any THC option?

Sorry, I should have know that due to the G83 beign used. The reason the Z isnt moving till the spindle is on, is beacsue your in feed/rev mode, but I dont know why the Z is moving..
Whats the start position of the Z?

Brian:
Any idea on this one, I havent used the G83 series in Turn as yet, I know the macro is new.. What are the parameters of it??

Thanks

Hi MArty:

DRill G83 X (optional) Z (mandatory) Q (Mandatory) R(Mandatory) G00 x0.0 z3.00
G83 Z-1.00 Q.1 R.1 F20
m30

So you have no retract distance, Set an R of .1 for example..
