Making a thc with resume cut button using thcud

Greetings....
I am making a thc by using thcud component
Also i want to add a pyvcp button to resume the cut on plasma

Logic as follows
When torch turns off
Sample x and y coordinates...
#here problem arises.... I dont know if i can store a variable in hal
Or will sample and hold component work for me????
Then when we pressed resume cut button
It goes to x y positions we saved earlier
Goto cut height
And torch on
Run

It would be great if any of u guys can help me... As I'm total newbie to hal
Thanks.... ☺

hi
plasmac got this option alredy
But as you say you want it by button
first the action you like to have is on ARC-ok signal of the THC
if this goes of motion.stop -> programm pause
then you press a button that runs a ngc
the location is in the var <_x> <_y> that you store in your ngc
#<my_x> = <_x> ...
then you move away to a location to see what hapens
eighter in g-code ngc or manuell
YOU can do
M00
do somthing as offen dirt or water is the issue
Resume on the pendand or gui
the g-code ngc will restart and move to the point
g0 z #<free>
x#<my_x> y#<my_y>
G0 z#<pierce>
s112 m3
g4 p0.5
g1 z#<cutheight> f#<cutspeed>
(end Button G-code)
and then it will jump back to the original g-code

Do i need to do it in a mousepad and save as ngc
Also how can i call ngc from button. Pyvcp

in the postgui halfile
net thc-resume pyvcp.my_button halui.mdi−command−XX

in ini
[HALUI]
MDI_COMMAND = o<thcresume> call

I really am at a loss to understand your constant posting on all types of plasma posts, many of which are well and truly obsolete. Since you started, plasmac is now part of the Linuxcnc master (V2.9) distribution and also in V 2.8 so it will be in the next official release of Linuxcnc. It is fully documented if you follow your nose to the 2.9 docs from the main Linuxcnc.org website. There is also a plasma primer document as part of the V 2.8 and 2.9 branches that was updated today (pending buildbot processing)
Please note:
1, Installing V 2.9 is a trivial matter that does not require compiling from source and it has the reverse run that you crave for.
2. Plasmac has a complete configurator. Read the docs.
3. Plasmac is by far the most complete Linuxcnc config for a plasma machine and the only one which is embedded in any version of Linuxcnc.
4. Consider then that Plasmac is the only officially supported Linuxcnc plasma config.
5. Many of us have been very patient and given you good advice. Many of us are sick and tired of your posts.

So my final advice to you is to:
1. Read the Plasma Primer in the LinuxCNC docs. linuxcnc.org/docs/devel/html/plasma/plasma-cnc-primer.html
2.Read the plasmac manual in the Linuxcnc Docs linuxcnc.org/docs/devel/html/plasma/plasmac-user-guide.html
3. Study the buildbot and work out how to install V2.9 branch buildbot.linuxcnc.org/
4. Install Master (v 2.9) branch. Ask for help if you get stuck in the correct forum section about how to install master branch
5. Follow the Plasmac user manual in Item 3 and install and configure the Plasmac config..

I'm sorry, if you can't do that we cannot help you further. We have been very patient. It is disturbing to read posts from others that say they find you annoying. It is your turn to do the right thing and put the effort in. I am unable to help you further and I am sure others feel the same.

im not
sick and tired of your posts.

as im also fighting with plasmac to get mashines transformed
there is as of me no time for all the new benefits to get solved

I will do plasmac shure when 2.8 is offical on the dvd and i will get a separeate hdd to get off
but on 1hr max saturday it is a way to go
change hdd install it
reconfigure to xhc-hb04 support

The simple fact of the matter is that there is no support of plasma for Linuxcnc before version 2.8
There are some configs on forum posts and private websites.
There is a Gmocappy screen set but there is no config behind it.
There are some components in Linuxcnc that may support some of those private configs.
So if you wish to persevere, and are unwilling to run the required version, you are really on your own.

The other thing is that the features requested in your initial post (eg. saving the X,Y position moving back to that position and resuming) is not possible in Linuxcnc. I actually discussed this off forum with another experienced member yesterday.

Some other plasma CNC controllers (such as UCCNC) support what you are looking for. But the fundamental difference is that they are not real time systems like Linuxcnc. We can sense loss of ArcOK in 1 millisecond. They can't. I worked out that my machine can coasts to a stop in 0.8mm on 2 mm steel. UCCNC needs to do what you wish to do because its not in real time like Linuxcnc. Its likely it travels a lot further on a fault. Reverse run and plasmac is your best bet. But you need to run version 2.9. (master branch).

u are saying i do not need to compile plasmac
then how can i get it ???
or i have to wait for next release ??

You do not need to wait for the next release. Just follow what I've said earlier and install master branch without compilation from source. Plasmac will be there in the SIms.

thank you rod for all the work going in and also phil the main dev on this
it will be a huge plasma jump
