Hi.
Mack3 version R3.00
Here is simple program.
(D3)
(S9000)
(without soj)
(x3.53 y0.419 instead of 3.55/0)
G00 Z7
G00 X2.1 Y0
G00 Z1
G01 Z-1 F50
G01 X4.55 F50
G03 I-4.55 (label #1)
G01 X3.55 (label #2)
G00 Z1
(othod)
G00 Z1
G00 Z7
(tail)
F500
M30
(kinec programi)
(-)
This program work out correctly several times in a row.
But then:
Instead of making full circle at label #1 it do small arc to a point X3.53 Y0.419 and goes up to Z7.
Next start of the program leads to even stranger results:
Program works fine except for the command at label #2, which is ignored. So machine goes up to Z7 at point X4.55 Y0 instead of X3.55 Y0.
More program starts - more strange things.
After PC rebooting program works correctly several more times.
Any suggestions?
