estop-latch is the right way to go  with these but a better way is to use joint.N.amp-fault-in IN BIT   Should be driven TRUE if an external fault is detected with the amplifier for this joint.

This will halt motion.
Your drives may also have a estop input which disables the drive on an estop.

Perhaps the information in this post would be helpful for you.

There's a couple of ways, you could use the Mesa Configuration Tool or you can add the estop_latch component yourself.

I'm not with the machine right now, so cannot run any tests (perhaps later today) but looking at the various hal state dumps I posted previously, spindle-at-speed seems to be showing false all the time, whether the next move works or not.
It does look like I need to check spindle-at-speed, but it doesn't seem like it is the deciding variable (at least not on its own)

Hello,

I am running a thre axis CNC mill with stepper motors with mesa 7i76eu. I wanted to connect stepper driver alarm outputs to mesa and have them triger emergency stop. I am also planning on adding two additional Estop buttons. I wired them up but then noticed that linuxCNC setup wizard only lets me select one output as emergency stop. Is there a way I can select multiple inputs as emergency stop, or do I have to wire the buttons in parallel and connect them to one input.

I've just purchased a 2008 Weeke Vantage 33 cnc router from scrap. The machine is in good condition and I'm going to convert the controller to lcnc.
The servos are Rexroth Indradrive and as best as I can tell they're using sercos iii. My drives have a fiber ring connection rather than Ethernet but the logo definitely says sercos iii. Apparently there were some iii drives made with fiber connections. 
The io is all Beckhoff and the pci card in the pc is beckhoff also. 
Is there any workable, straight forward way of controlling these drives using lcnc and, perhaps, the beckhoff pci card? 
If so then great, much better to use the hardware as is. 
If not then I'll go down the path of selling the rexroth drives and motors and buying Delta or something along those lines. 
Any info of advice greatly appreciated.
Cheers

If I do the move without turning the spindle off it will wait for the spindle to reach speed and then proceed.
Do you think the issue might be with spindle_at_speed after the M5?

i really don't have any questions at the moment, from what i have seen with the Vismach models it usually gets tethered to axis and has it's own space to run alongside Linuxcnc what i am trying to do is roll everything into one screen if that makes any sense? i have not seen anything like it so basically all been uncharted territory for me. i would say it would end up being something like what you might find in the machine builder of fusion 360 if it would actually come together 100% when i get done.

No, I don't have any kind of output connected to the MESA

Not exactly sure what your question is but vismach model simulation uses values from hal pins (usually joint positions) and is thus independent of what gui is used.
Are you trying to embed the vismach window in the probe basic gui?

Hello everybody 

I wonder if the very often linked Google document from Rod is still available?
docs.google.com/document/d/1jeV_4VKzVmOI...diY/edit?usp=sharing
Google says the file was deleted?

You have encoder feedback ?

So I took some time and created a generic driver for EL2502 that works for me. I can control frequency and duty cycle with two seperate 16bit integers. This has been tested only in one channel but for second channel, PDOs should be 1603 with the same sub indexes as for the first. 
SDO index 02 is to set control number from SINT16 to UINT16 and index 07 to change operation mode to frequency AND duty cycle.
I hope this helps you.

I found my self in a situation where i could end up getting sucked into the lathe department at work and had an idea to build some kind of test simulation for testing macro programs and testing of programs in general. So i thought it would be neat if i could create some kind of virtual machine for this. i have never tried anything like this in the past so who knows how far i can push the limits with what is able to be done with the tools we have here to work with? Being a mill guy for the most part and looking at lathes with a main and sub spindle with XYZ with a 4th linear axis on the sub spindle for part transfers and phase snyc on both spindles with some of these lathes having a second turret on top of this kinds makes you take a step or two back to get your ducks in a row when your in a situation where there is no one to ask questions because the last guy that knew these machines ends up retiring. So that's basically how this project came to light

what i have managed to do so far is get all 3 of these programs to play nice together open up and render my model and create a 3D orbital view with a zoom feature with a custom viewer so far. i almost gave up on this project quite a few times but got things working this past weekend. i am not just getting into the custom UI with designer which i am just now starting to understand a little bit.
added a screen shot of the model to give you and idea of what is being worked on this is by no means final or even close to being done. i had no idea what i was getting myself into when i started this and thought it would not be to much trouble until i started and that went out the window pretty quickly once i dove into it  

 

The boards looks nice, is it a hobby or are you going to sell them?

I guess you already know this but just in case, here is how you create individual pins for i/o
