Hi, i got a friend of mine wrighting a little m6 script for me as i change my tool manual on my BT30 spindle, script does what it should do, but i got a problem that it sometimes locks UCCNC up abit, if i do an M30 in MDI, then it gets good again.
But this does not work when cutting a part, as it will offcourse stop the gcode file and heat to start again on the first tool change done.

Anyone know why this messes it up ?

(I tried adding M30 at the end, but commented it out as it messed up)

Try to overlook the Norwegian language inn here

Having a quick look, a couple of things I noticed:

// Slå av flood
exec.Code("M09 should be exec.Code("M09");
while(exec.IsMoving()){}

And at the bottom although it is commented out, I see the same thing:

// Stop script
//exec.Code("M30 should be //exec.Code("M30");
//exec.Wait(200);

thanks, will correct that, anything else that could get the cnc to act up ? it does do it's job, but all og the sudden it will just stop working when doing manual tool changing.

Add some messages to the status window after each step so you know where it's stopping.

good tip ger

Hmmm, that's interesting.

Looks like the forum is removing the "); off the end of the code in my previous post.

i belive so too, as when i checked the macro on the cnc comp, it was fine

HOPEFULLY THE FORUM DOES NOT KEEP CHANGING THE CODE I WRITE...............................
EDIT - YES IT DOES , SO I ATTACHED A SCREENSHOT OF WHAT I WROTE.



Aha, then what about this line:

exec.Code("G43 Newtool);

Should it be exec.Code("G43" +Newtool);

This is the notes from the UCCNC manual on G43:

Tool Length Offsets : G43, G44 and G49
To use a tool length offset, program G43 H…, where the H number is the desired index in the tool
table. The H number should be, but does not have to be, the same as the slot number of the tool
currently in the spindle. It is OK for the H number to be zero, an offset value of zero will be used.
It is an error if:
• the H number is not an integer, is negative, or is larger than the number of carousel slots, which is
currently set to a value of 20.
The G44 command is similar to the G43, but for negative tool length offsets.
57/87
To cancel the tool length offset compensation, program G49.
It is OK to program using the same offset already in use. It is also OK to program using no tool
length offset if none is currently being used.

So should it be exec.Code("G43 H" +Newtool);

I have currently set the spindle nose as tool 0 and every tool is calculated from that, so all tools are positive from that offcourse.

tool changes works, but now and then it stops working after tool change is done.
the machine just does not reply to anything, but if i use MDI and type M30, it works again.

it's like it is not done with tool change.

i have since then removed the reply that tool change is done, as i got tired of getting pop up message that tool change was done + pressing cycle start after.

i dont have a tool rack yet, so changing out the tools by hand (starting to get tired of that, so have plans of adding a toolrack perhaps at the end of the year)
