TCP 5-axis kinematics

This error unlikely related to the branch but might
be caused by improper environment setup (sourcing
proper rip-environment) or maybe conflicts
between multiple rip builds and/or installs on
the same machine.

Please post:
1) output from the command: linuxcnc_info
2) tar file of the configuration directory
3) log files:
/home/paju/linuxcnc_debug.txt
/home/paju/linuxcnc_print.txt

You’re probably right. I was eager to test it but had only a little time and now that you say that I don’t recall having sourced the env.

Will check when I’m back home.

Honestly not quite sure what tainted that terminal window ... I had used it for the test from yesterday but I did source the new directory earlier, I can tell since when I tried to source it now it gave the usual message that it only needs to be done once "This script only needs to be run once per shell session.".

No matter, I started a new terminal and sourced the new dir and the error was gone.

So, without making any modifications to your code and simply adding HOME_INDEX_NO_ENCODER_RESET = YES to all axis that have HOME_USE_INDEX = YES, I was able to home successfully multiple times and on all axis using index pulse.

Just to be clear, had the changes not worked, the home sequence would, after finding the index, send the axis to a home position that is not the one configured in the ini file, eg. MIN=0, MAX= 400, HOME_OFFSET = 200 but final move would for example take the axis to the right most end of the AXIS position instead of the middle. Also, the travel limits would be messed up.

So the test is successful - Thanks again.

Could you please keep me updated on the success of this code making it in?

Damn, you did it first. My HDs are still laying in the corner...

Oh wow very nice collection, now I know why they are hard to get on eBay you’ve been snatching them all

I still have another two but without integrated servo.

Despite what they say, better second than third;-) hurry up.

I had mine for about a year stored away, while the concept was brewing in my mind. If I knew where to get cheap custom casts I would have done it slightly different.

Nice thing is that the 5th axis can be swapped easily for any other setup, so it’s a modular design. While I’m exploring the current setup, many other ideas are brewing, many of which may never see the light of day.

How does Linuxcnc handle softends with TCPC? does it automatically stop when the physical axis hits the softend or does it just go through? (until it hits the endstop)
