Thanks phill that looks like the right place to look.
When pendant.hal is commented out on its own:
The breakaway pauses the program but only during the rapid movement.
nothing else changes.
When runstep.hal is commented out on its own the following happens:
The breakaway works correctly and stops the program in the event of a collision.
The cut recovery panel comes up when the pause button is pushed or a break happens causing a pause.
The z safe travel height is working as it should.

Do any of the issues change if you run the machine with the references to runstep.hal and/or pendant.hal commented out in the ini file?

Hey everyone,
New to the forum so be gentle.
This post is about the upgrade happening in my workshop at Steel Cut and Create in melbourne.

Firstly in case anyone wants to know Rodw has been great to deal with from the first contact. I have been very impressed with the work he has done on his end. We have progressed through a range of issues and he is very clever and has stuck with it the whole way. It has been difficult because he is doing all of the work remotely, but everything that Rod does is documented soo well that there is always a starting point for troubleshooting.

I have uploaded a video of our current situation to help with trying to get a solution:
drive.google.com/file/d/14DREIxArgDyoQFU...4u3/view?usp=sharing

I will make a better video of everything once it is all finished and running properly.
Regarding the control box on the gantry--- Did it have to go there? No.
Did we consider mounting it seperate? Yes.
Did I do some testing on the old system with extra weight to see what would happen? Yes.
Now that it is all in place I do not like the control box running around on the gantry, but it isn't a big deal because the project still has a way to go before it is finished. I will plan to move it off the gantry now that I see the effect. This decision will be in an attempt to reduce pressure on the running gear (pinion gear and rack, motors); to be able to increase the speed of operation; and to reduce the impact in the event of a crash.

Reading how much you like being on the "bleeding edge", I'm a drop curious why you didn't use the master branch? It does have a few more features that are not present in 2.9. It's also noteworthy to mention that at this point, 2.9 is considered "end of life" from a development standpoint (to include bug fixes).


Thanks. I actually asked  here which version to use for production and 2.9 was recommended.
forum.linuxcnc.org/plasmac/53044-best-qtplasmac-version-to-use
I also built the 2.9.x ISOs on the Linuxcnc downloads page soi maybe I am biased. For a production setting on a machine 1800 km (over 1000 miles) away for a user, using a production version  made a lot of sense.

Its not that the buildbot is broken but V2.9 is frozen following a release. Release debs for  2.9.3 are in the Linuxcnc repository which can be installed on any linux distro by running the bash script mentioned here 
linuxcnc.org/docs/stable/html/getting-st...th_preempt_rt_kernel
(or by using the ISO)

Checking the release version of QTplasmac in Linuxcnc 2.9.3 , I see it is 2.9-238.314. It seems your last release for 2.9 was not included. It will probably get in there if ever a 2.9.4 is released.

I might write a script to convert from using the Linuxcnc repos to the 2.10 repos at buildbot2.highlab.com/

 

Yes, I understand the difference between the released debs and the buildbot(s)... the key word there was "if" you used the buildbot(s). Either way, the buildbot(s) is most definitely broken and I'm officially sorry I said anything.

Anyway off topic for long enough, The main issue for us is the breakaway. It really makes no sense that it will not work when all the pins are set correctly as inputs into plasmac.comp. I will look at the state of the plasmac.comp output pins to halui as it might not be a qtplasmac issue. All of these features were working years ago so its odd they have broken.

 

QtPlasmaC does not appear to be the issue:

From what I understand, this is the ISO that is to be downloaded, am I right?

Here it was all packed up for shipping, (Plasma in a box) 

Did you zip it? :)

Yes an electric strapping machine zipped it up tight :)

Thanks Tommy,
The other needs to stay a sticky as it has a lot of additional steps that can't be scripted
This one just allows people to install the repositories if they are not on their version of linux or the etherlabmaster's security key changes (which will happen every 2 years)

Mods might like to sticky this as some people have needed this recently (Due to point 1)

 

Done, thank you.
Should we unsticky the other topic?
The titles are very similar.

Notes from installation of ethercat on Raspberry Pi 4

Category: EtherCAT

That 4 year old tutorial is obsolete. It does not use the current version of linuxcnc and ethercat has changed many many times since. There are much easier ways today.
1. Download my 2.9.3 image I linked as it includes the ethercat repository already installed
2. Follow these steps forum.linuxcnc.org/ethercat/45336-etherc...-how-to-step-by-step

7i96s +7i83 trough 7i44 is it possible?

Category: Driver Boards

it's clear, thank you very much. I am currently at the stage of testing encoders pinouts and siemens drivers with an simple battery, I was waiting for the repair of the 7i77 to resolve the dilemma of what to order, 7i96s or 7i92 or maybe 7i97t. since it's 7i77 hope it's fixed, I'll order 7i96s... so I'll get back with news...

The 2.92 image required use of balena etcher to burn it
It looks like the release manager has not released the  2.9.3 Image I gave them. Try this one
