I also cant see why it works ok in manual calls with no code loaded (see video) but fails when in code mode????

Ok, i'm getting closer :)

It seems if i call all tools my the MDI it works, but will verify this with a repeat TC code program in a minute.
When you call a tool by MDI using M6T100 the Z DRO does NOT change.

Now, before i always set my Haimer probe by typing 100 in "Current Tool" DRO on the 2010 screen-set - do this and the Z DRO gets TLC applied to it - this is the cause of my issues i think, looks like the "Current Tool" DRO runs G43 H********* when you press enter on it - thus the cause of my lost Z travel.

I'm off to run some more tests but it feels like I will have to remove the "Current tool" DRO for safety reasons and do it all MDI, no biggy.

Nope, failed again :(

I manually ran through my whole tool rack, 20+ tools using MDI TxxM6 G0Z0 and every time it worked perfectly 100% tool on the TOM.

Loaded up the code, soft limit on Z Min warning, bypass, crash(e-stopped to avoid) The Z axis just dives.

Here is the screen after i stopped - the Z axis is at +85 and the code is calling for Z2 ??


The Offsets screen...


The Z of 186mm is about right - i had the z at about +30 when zeroing with the Haimer which is about 150mm long.

So, i'm stuck again - it works well in manual but can't run code :(


Have attached the exact code file below.

Probably digging myself in deeper here but could it be how i have my tool table setup?

I measure all my tools in a height-setter which feeds the result straight back to Mach TT, all tools have a height including the Haimer probe.

Now, i just went back and put the probe back in the spindle, and the Z was off by exactly the height of the probe - this is why it crashes.

BUT why only in code and not manual - it works perfectly in manual.

So confused now.

hi,

is it possible that your are doing th TLC twice ?

1. with the c-axis (knee)
2. SetCurrentTool(Tool) (m3 internal TLC)

just thinking while i went through your post's.

Thomas
anything is possible, just try it.
if you find some mistakes, in my bad bavarian english,they are yours.

I was unaware what setcurrenttool actually did - that may be a lead there, thanks.

If i leave setcurrenttool out, any idea what would happen??

do a little test to see what Setcurrenttool does.


-load 1024.set
-put in the tooltable  height 10.0 for tool1
-enter tool 0 in the tool Information dro
-push zerro z button
-enter tool 1 in the tool Information dro
-watch z coordinates

i think, as far i have walked through your code,it will work like you expected,
because the TLC is done by your c-axis.

NAILED IT!

Well spotted, TPS,

removed the Setcurrenttool line and it all fell into place :)

You can use the "Current tool" DRO anymore as it has no idea what the current tool is but i can live with that, i guess it could be fixed by adding a line to the macro that sets a pseudo current tool DRO on =screen to show the last selected tool call.

But its all working, part made, no mess ups.
