lol, here we are, 9 years later and still no manual tool change? That came unexpected to me, as I find it hard to understand why to just stop disabling jogging and let me jog just like mach3/4 and let me reset Z at any position. Seems dead simple... seems like that is gonna ruin my day today haha

Really ??????

Hi Andy, I am here with the same problem, and I agree that manual tool change is a pita. I can easily setup a sensor tho, right on a side of a bed for example. I am not very experienced in coding though, Could you please guide me in the right direction, maybe there is some sort of basic guide on setting that up anywhere?
 


If you use the Gmoccapy GUI then tool-length probing is integrated in to the GUI (with a few config tweaks):

Thanks a lot for the link Andy, gonna dig into that tonight then! .. to call that a "few" is a stretch tho, haha. I have a feeling that whoever wrote that documentation spent much more time and more effort to make that text than it would take to just improve the software and just implement these features in an easier way so we all don't have to do the same programming task on our computers million times (for million users), to make them accessible to non Linux programmer people, like myself. I'll eventually learn this and figure it out, but maaaan, that so inefficient... :(

been trying to setup a simple basic probe on GMOCCAPY and turned out it requires a flight to the moon and back to have that basic function working. I am heavenly shocked how this software doesn't have simple probing functionality even, and expects you to code it yourself. Having a trillion errors, docs are awfully written, wrong paths everywhere. I guess gmoccapy author assumes that everyone knows certain things, like folder paths, especially when he puts incorrect non existing ones into his docs. Anyways, that's a disaster. Do you guys think switching to Axis GUI is gonna make it simpler and more straightforward and refined? Haven't tried it yet.

 You must copy the following files to your config directoryFirst make a directory python in your config folder from your_linuxcnc-dev_directory/configs/sim/gmoccapy/python copy toplevel.py to your config_dir/python folder. Copy remap.py to your config_dir/python folder Copy stdglue.py to your config_dir/python folder.From your_linuxcnc-dev_directory/configs/sim/gmoccapy/macros copy on_abort.ngc to the directory specified in the SUBROUTINE_PATH see  RS274NGC Section . From your_linuxcnc-dev_directory/configs/sim/gmoccapy/macros copy change.ngc to the directory specified as SUBROUTINE_PATH see  RS274NGC Section . Open change.ngc with a editor and uncomment the following lines (49 and 50):

This part alone should have anyone worried. "your_linuxcnc-dev_directory" , "config-dir"... seriously, ffs....

Seriously considering selling all linux setup and going back to mach4+pokeys57. Counting time alone I am already $1000+ in loss just setting that all up just by hours of struggle alone.

For Axis you might also have a look here: 

In the comments of the video you find the link to the files: www.talla83.de/linuxcnc/WZ-PROBE.zip
The only thing I had to do is cancelling the TLO a bit earlier than in the original file:

Instead:
...
G53 Z#1702            (Wechsel Z Position)
G53 X#1700 Y#1701        (Wechsel XY Position)
M6 T#<_selected_tool>

G53 X#1801 Y#1802       (Taster Position)
G53 Z#1800            (Sichere Z Position)

G43.1 Z0            (TLO reset)
...

I hat to do:
...
G53 Z#1702            (Wechsel Z Position)
G53 X#1700 Y#1701        (Wechsel XY Position)
M6 T#<_selected_tool>

G43.1 Z0            (TLO reset)

G53 X#1801 Y#1802       (Taster Position)
G53 Z#1800            (Sichere Z Position)
...

Otherwise I got the message that the file exceeds Z limits...

 I have a feeling that whoever wrote that documentation spent much more time and more effort to make that text than


Linuxcnc brings the advantage of maximum adaptability. I always look at the manual from this point of view. It is not about showing a way, but to enable the user to implement his own way. Without a lot of training or programming experience, it's difficult (that's how I feel, too). But hey, there is fortunately this forum, Youtube and other sources of information. I am glad that there are people who develop and document such a powerful free tool like Linuxcnc in their free time.

Best wishes

Jan
