 I'm integrating a HITBOX HBC65 plasma cutter with LinuxCNC/QtPlasmaC via its CNC interface (AEC ready signal). Looking for documentation or first-hand experience on:

• Pinout of the CNC interface connectors
• Signal type/level of the AEC-ready (Arc-OK) output — is it a dry relay contact, open-collector, or a voltage-level signal? What voltage/current rating?
• Whether the arc-voltage-divider output is already isolated/scaled, and what the scale factor is (V per V, e.g. 1:50)
• Torch-start/pilot-arc control input requirements (voltage, active-high/low)

Manufacturer documentation seems sparse — has anyone reverse-engineered or received datasheets for this specific interface? Happy to share results back once I get it running.

hi, I'm very interisting at the sscnet control board,i want to try your product,how can I get it?

looking good. In the commercial software I used, they defined a list of upper and lower tools and material.
So then when you defined a job, you included tools and material so you could save for later. Over time I tweaked my regular jobs so they were perfect. Mainly tweaking that back gauge position.

Some screenshots of my first shot at this. In the bend editor, clicking the bend angle setting will open a whole new page with dies and steel selection. Which will auto-fill most of the remaining values below it.

Now I think I should indicate on the main screen what dies and plates are selected.

Exciting! I'd recommend your bend list has a angle adjustment setting. set your first bend to underbend and then add some adjustment as different batches of steel can vary. Then on the job, assuming you have a batch of identical parts, tweak the adjustment field on the first bend to get it perfect. also your gui should let you set the upper and lower tool dimensions, material and thickness. Armed with all that, the maths is available to calculate the stroke length automatically.

With all the frustration, and countless hours of documentation research, I devised a plan, an AI plan. After a few months I had this working, But Sadly some how this project got leaked without my knowledge, and my home network, and phone was compromised, and every time I start my machine it tries to kill it's self in some manner. Wish I was a network guru, but I am not. Guess I offended someone... 

This project led me into a C++ refactor, and that led me into another unrelated project, that used some features from my implementation of a trajectory planner. 

If you are using the ethercat version from  linuxcnc-ethercat, you need to change your hal file to activate things

The part laying on the white book was the first steel this machine bent in years. Some of the photos turned out tiny. I'll have to try again later.

Thats cool. I passed the plasma post processor on to Brad (sliptonic) wondering how it can get into freecad. He's the Freecad CAM man.
A lot happening here. Brad put a PR into linuxcnc for MTconnect and he now is querying Linuxcnc machine specs from freecad CAM.
5 axis  3 +2 will be in the next release.
And a blog post from Brad about 5 axis. sliptonic.com/posts/machines-cheap-toolpaths-not/

So after a break doing various other things, I'm back trying to get these drives to work, but hit a couple snags.

This is on a fresh install of 2.9.10, on an Odriod H3.

First is that I can't get the permissions to work after a reboot. If I do the sudo chmod 666, everything works.
I've added the KERNAL rule as per the guide, but it doesn't work after reloading the rules.
That is a pretty minor thing that I can look at later, but I'm open to suggestions?

The bigger issue is, does anybody have a example HAL/ini files from a newer version of LinucCNC?
I've copied my files from my original post, but am getting a servo-thread not found error, and all the fixes I've tried so far have not worked for various reasons, so would like a basic example that works, but my google skills seem to be lacking tonight!
 

Sorted it thanks ,

Think docs need an update to reff direct download from Mesa is now needed or such

Config Files attached.. I am using Technic and the high level feedback line to determine that the steppers are homed when they are enabled. The steppers will go to a hard stop then come back 1 rev for the home position, when this is done they signal this through the HLFB output. Other than that I think the configs are normal and haven't chnaged since my original install a number of years ago.

We want pictures or videos or smoke signals...

How about this?
I drew this first sketch in LibreOffice Draw.
The plan is for most of the fields to be buttons. Touch a bend in the scrollable bends list to jump to that bend. Touch the filename to open the bend list editor which will include load/save etc. buttons. User/Status might open a dialog with login/logout buttons and status/fault log.

Maybe this needs/wants some kind of bar chart displaying tonnage and servo load% near the bottom? The press brake I'm working on does not currently have those values available in hal.

You need would update your LinuxCNC to say 2.9.8 to support version 3 of the PktUART

I'll take a look at the MPG issue.
