Hi experts !

Really need help on this one, I work on a 840D sl ver 4.08,

and I'm trying to activate working area limitation (see pics),  in my program.

I can put values for the + and - limits for a specific axe with parameter SD43420 and SD43430,

but for SD43400 and SD43410 , I need to put 1 manually, or put a check mark in the box on the

working area limit page to enable these limits, but I want to be able to do

this in my program. My goal is to prevent my table to move temporarily. That way I could

build a small macro or M code to activate and deactivate securely.

And the pics are from sinutrain V4.93 HF5.

A big thank to all.

Hi,

Working area limitation in BCS (G25/G26, WALIMON, WALIMOF)

Pee

Thanks Pee, did try G25 and WALIMON, it's ok with G25, but WALIMON

as no effect ! Should I see a check mark in the Working area limit page ?

Thanks again

Hi,

The programming manual example show:-

N10 G0 G90 F0.5 T1
N20 G25 X-80 Z30 ; Define the lower limit for the individual coordinate
axes
N30 G26 X80 Z330 ; Define the upper limit
N40 L22 ; Cutting program
N50 G0 G90 Z102 T2 ; To tool change point
N60 X0
N70 WALIMOF ; Deactivate working area limitation
N80 G1 Z-2 F0.5 ; Drilling
N90 G0 Z200 ; Back
N100 WALIMON ; Activate working area limitation
N110 X70 M30 ; End of program

I've never looked at the checkbox. I don't really like the function because it sets an area you cannot go out of like software limits whereas I would like to define an area that has to be avoided. e.g. a steady or a fixture.

Pee

I see what you mean about the area to be avoid. And here a page of a book that explain it again,

but like I said, WALIMON as no effect, at least on my controler.

Thanks again

Hi,

Try setting the checkbox on to enable the limits and see if it then switches on/off via program. You can also write directly to the setting data bit with $SA_WORKAREA_PLUS_ENABLE = 1

Pee

With a check mark in all the boxes and with WALIMOF, it won't turn off.

It won't let me either change it by $SA_WORKAREA_PLUS_ENABLE=1,

see pic attached for alarm.

Thanks again.
