G2 and G3 MDI problem

[johu]

Hi there,

I use UCCNC Version 1.2111, and a UC300ETH_5LPT.

My MDI doesn't respond on G2 I10
also nothing on G3 I-10
Is this normal?
I would expect full circles, but UCCNC is quiet.

When loading the following program, everything works as expected...

Code: Select all

G17
F1000
G0 X0 Y0
(CW circles)
G2 J 10 (North)
G2 I 10 (East - NOT ON MDI)
G2 J-10 (South)
G2 I-10 (West)
(CW circles)
G3 J 10 (North)
G3 I 10 (East)
G3 J-10 (South)
G3 I-10 (West - NOT ON MDI)
M30

MDI probably needs an X and Y?

Tried it again today, could't reproduce the problem.
Both with and without X and Y parameters on the MDI.

Strange...

Sorry for bothering.

Maybe you were on the wrong plane, e.g. if you were on G18 or G19 where the parameter I or J might not be OK depending on which plane you are, then IJK combinations have to be coded to fit the current selected plane. Ofcourse this is just an idea about what could have went wrong.
