Mesa 7I96 + Renishaw LP2 probe

Hello @andypugh,

I've been waiting to spend time with it for a long time, it seems easy, I'll try to try it, thank you very much.

Hello @andypuig,
you are really good, thanks for the help you offer in the forum.

Ok guys the results are in.

It turns out that i actually have an attachement to my LP2 probe that does the job of the MI8 unit, so that was a redundant purchase.
The unit i have after my probe is called FS1i or FS2i socket.

I got the probe working sending a signal to the Mesa board, the trick was to wore the red wire to 24vdc, the blue wire to 0 and the yellow and green wires are contact wires.
I wired the yellow wire to the Mesa board and the green wire to 0vdc. Sucess the board now has a signal on input pin and the diode is activated one the probe is pressed.

Now i just have to figure out how to change my toolprobe input in my .hal file to make the pressing of the probe register during my toolprobing rutine. The signal goes through the software on pin 9 and registers, but the tool change rutine doesn't react top the probing.

Im using this tool change rutine if anybody can help?

Ok news again, I got the probing to work and it seems fine expect for after a tool change.
I only had to opportunity to do a short test run last night but it throws this error (see attached picture) as soon as the probing is done after the 2nd probing has been done (after tool has been changed).

See attached picture.
I don't know why, the Gcode is asking for position Z15 but I don't see why that should be out of machine limits?

Again thank you andy for your contribution to this comminity and topic.
I read up some more and realised that what i needed to du was remove the G43 line from my Gcode cutting files, after this the offset works!

I guess sometimes the answer is simpler than you think:)

Andy, how would i do that?
Also i have been milling a few items now and the toolchange rutine is not reliable.
I have tried more than once now that the offset was not set correct after a toolchange even though i started with an M600 before running the program.

I have noticed that the software adds z lengths in the tool.tbl file is this something that could cause this type of issues?
