THC config that works.

With my plasma, I have to initiate in contact with the tole and then to rise of about 2mm.
With this config I have to modify something in the gcode or in this config?

No modifications.
See picture, pierce height is there so you can set it as you need.

Dear Tom,

This may be quite out of context of the topic, hope you will help. In your configuration, you suggested that user can start from where the machine stopped maybe due to a power failure. I'm using LinuxCNC for driving a wireEDM and I want to equip my system with that same feature. As I'm Indian here in India we do have power cuts without being notified, also wireEDM'ing is a bit slow process often we need to halt the job work for any of reason so this will save our time a lot. Can you mention how can I do so to achieve same in my system?

Thank You.

You need to create an empty file with the name last_position.txt and add an entry to the ini file pointing to that file. That is it. It is mentioned in this thread so just have a look.

That is NativeCam or NCam for plasma. It is very usefull for a lot of work done on plasma machines as you can instantly make a part, see it on screen and just run it to make that part. There are 2 threads about it on this forum.

Dear Tom,


Correct me if I'm wrong.

Let's say there are ten lines of G code required to be interpreted for completing my cutting task, but a shutdown occurred when the Linuxcnc was at line 5.

So, after power resumes, I restart the machine take the data from "last_postion.txt" file, recreate the G-code again using a cam program, and again start the cut?

Or in your configuration, the g-code interpreter starts from line 5 position itself.

Regards,
Kunal

After power loss turn on the machine, note where it has stoped, jog to X0 Y0, home, select the line it was stoped at, rigt click on that line and choose "run from here".
Side note: "run from here" will not work on arcs so scroll up to a line with no arcs ( no I and/or J values ).

I've just finished my float switch setup and I'm trying to get the initial pierce sequence to work. My switch has 1mm of travel before activate (ie blue float switch indicator comes on). I'm cutting 3/8 mild steel so I've set the initial cut to 5mm and a delay of .7 sec. The z axis will go down, touch off, go to ~8.3 mm, and fire. This is of course to high so it just repeats.

Is there another setting I'm missing? Why does it go to 8.3mm instead of 5mm? Do I have to set something with the touch off button?

I'm a little confused as well on what the sequence is to initiall home the z axis. It seems if it is not high enough it will go down and hit the limit switch which cause a joint 2 error.

Thanks for advance for any help you can provide.

In the screenshot you have active offsets, so cancel them. Also make sure you have the correct scale for Z axis as that will mess up the height.
