Circle movement not working
#1
I am trying to create a circle move (1 quarter - 90 degrees) using the prog1.pmc code as below:
undefine all
&1
#1->1711025 X
#8->1365276 Y
#2->2105867 Z
#7->393216 a

open prog 1
ta 125
ts 35
tm 1000
dwell 2000
G17
G91
G02 X0.25 Y0.25 I0.25 J0.25
close

For G-Code commands, I have also created subprog1.pmc as follow:
open subprog 1000
N0: rapid return;
N1000: linear return;
N2000: circle1;return;
N3000: circle2 return;
N9000: dwell 10 return;
N17000: normal K-1 return;
N18000: normal J-1 return;
N19000: normal I-1 return;
N90000: abs return;
N91000: inc return;
close

However, the output is just a LINEAR movement from current position to point (0.25,0.25). I tried several other ways, such as using circle1 directly in my prog1.pmc but none of them worked.

Can anyone help what might be the issue here?

Thanks,

Have you set Coord[x].SegMoveTime to a value greater then zero?

Thanks for your response. I set Coord[1].SegMoveTime=10 and still it moves linear not circular. Is there any other parameter that I should change to have a circular move for X and Y?

I think the move command you want is:

G02 X0.25 Y0.25 I0.25 J0

This specifies the center for the arc as +0.25 units in X from the starting point and 0.0 units in Y from the starting point.

Your move command specifies the center point the same as the ending point. It is not mathematically possible to create an actual arc for that.

I can't believe it wasn't Coord[x].SegMoveTime

Don't forget to Incremental Arc Center vs Absolute Arc Center. You don't have G90.1 or G91.1 defined in Program 1000.
