G83 Lathe

Post by tmday7 » Fri May 24, 2019 11:28 pm

Hello,
I am trying to do run a simple spot drill G83 program on my lathe. For some reason iam getting a pop up window when trying to run gcode that states"Y value unspecified in xz plane canned cycle". I have ran this same program a few times a couple days ago with no problems but now it gives me pop up and halts program. The gcode i ran before this was a finish pass od profile.
Any ideas what is wrong?

Code: Select all

(.5 SPOT DRILL)
(Material D-2)
G18
G20
G54
G90
G94
G0Z1.

Hi Troy,

The Drill Cycle assumes you are going to drill in the axis perpendicular to the specified plane. So for example a standard milling machine would use G17 to specify the horizontal xy plane and then drill in the z direction. If you specify G18 to specify the xz plane then the interpreter will drill in the y direction so the interpreter flags an error if y is not specified.

Try specifying G17 xy plane if you want to drill in z.

I'm not sure how this could have worked before.
