Hi Richard,

Been forgetting to reply, sorry for that.

I have not converted the Renishaw routines to LCNC, rather I coded from scratch my own which I have shared here, both for the 3D probe and Toolsetter TS27R.

Wish I could help.

Best Regards,
Paulo

Hi Paulo,

Your post has already been very helpful in giving me an idea of what's involved - thanks again for sharing.

Best wishes,
Richard

I'm not having success integrating this code with probe screen as suggested.

I believe the probe screen python code is using linuxcnc call stat.probe_position() to identify where the probe was triggered after each move.

Since the code supplied pulls variables #621-#628 (offsets) through a Gcode subroutine and adjusts the measured probe value within the subroutine into variable 5001 and 5002 probe screen is missing the offset.

Anyone else have this issue? Are variables 5001 and 5002 special? Maybe i'm missing something.
**EDIT - I think i understand . This code is attempting to change the absolute position on the mill before probe screen has a chance to read it. Isn't that dangerous? Would it not throw off the homed location? Probe screen still would never get the result because it is determining the probe trip point from the previous G38.2 calls which do not include the offset table variables.

The probing calibration routine worked great. I agree with what was calculated. Thank you plopes9000 for your efforts!

Hi CrashCNC,

Looking at the code again, I believe you are right that the integration with probe screen is not taking the compensation into account.

We would need to change probe screen to take the result from user controllable variables.

Don't think I will get the time in the next days, week to work on this, if you get it working let us know.

Best Regards,
Paulo

Hi Richard,
did you get anywhere with this? I have the OM40-2 probe and OTS tool setter connected up but to be honest I have just been using them in the most basic capacity, tool setting (length by touch, no rotation) xy and z. I would like to use to use it more! I have not seen anz renishaw macros etc..

cheers,
john

I have just got a OMP40-2 and I will have a look to see if I can make the probe screen work with calibration.
I have also made a modified Fusion 360 postprocessor for linuxcnc that output probing code. For the moment it is the same as the HAAS post-processor. My goal when I have time is to write macro for G65 xxxx that emulates the renishaw macros. They are well documented so there are already a lot of work done there.

Very nice there Per, writing macros is way over my head ;) Looking forward to that maybe I can get my MP10/OMI to work.

You are here as well :-)
I just installed the probe, and it is a fantastic help! Setting up jobs i soo much faster.
You should absolutely install your probe. The probe-screen works nice as it is when you have lernt it.
I just wanted it to be as correct as possible.
I run small series that require high precition so I will try to use probing in Fusion so I can probe every setup automatically.

Hello

would you benefit from the routines of Renishaw MP12 & TS27R?
I just converted a micron VCE1000 (Haas) to Linuxcnc.
On the old controller the Renishaw routines were stored and I have the original Renishaw disk.

Greetings
