CS-Lab / shifts / offsets after some machining time with CSMIO IP-M

« on: February 20, 2023, 02:34:20 AM »

Following the installation of a CSMIO IP-M controller on my cnc (6040), I have shifts in the working origin after a certain machining time (about 1 hour with a lot of circle machining). This offset is in X, Y and Z and is always in the same proportions (about 5mm on all axes, positive offset in X and negative in Y and Z). Despite several attempts to adjust the motors (step/mm, velocity and acceleration) I still have these lags. There are no mechanical hard points on any axis (it worked fine with the old interpcnc controller).
The attempted machining is on a work surface of approximately 400 x 550 and with 25 holes of 22mm diameter and 18mm depth.
I use Mach3.
What can I check / change?

General Mach Discussion / Mach3 M98 ignored

« on: February 15, 2023, 07:08:13 AM »

Hello,

I have a problem with M98 subroutine in Mach3.

If I run this gcode file:

Code: [Select]

G90

F2000
G1 Z -1
G1 X0 Y0

G91
M98 P1000 L4
M30

O1000
G1 Y200
G1 X200
G1 Y-200
G1 X-200
M99

%

the O1000 is never executed. When running in step by step mode, when the M98 line is focused, next step is M30 and not O1000.

If I wrote a second gcode file (1000.tap) and put it in the subroutine folder like this:

Code: [Select]

G1 Y200
G1 X200
G1 Y-200
G1 X-200
M99

%

and call it inside the main gcode file:

Code: [Select]

G90

F2000
G1 Z -1
G1 X0 Y0

G91
M98 (1000.tap) L4
M30

It works.
I try with .066 .062 and .043 version and it doesn't change anything.
Do you know where does come this problem? I haven't found answer on internet.

 

Thank you
