Another plasma component...

Hi everyone
Finally yesterday I could get the PlasmaC working, I only can say absolutely amazing thanks for this great work.

Glad you like it.

I am close to being able to incorporate Powermax communications using a modified version of your hpmx component. Before releasing it we should put the standard GPL header and copyright notices. As the author of the original I think you should be noted in those comments as well. If you could post your name as you would like it to appear I will add it and post a copy here for you to check out.

A quick question. In hpmx.py you read the registers with a read_holding_registers and in the Hypertherm application note they use read_input_registers. I don't have a Powermax to test with so I made up an Arduino as an emulator but I have used read_input_registers. Do you know if that causes any issues.

Just tested the latest version of Linuxcnc, plasmac configurator does work as it should except for two lines containing toolchange-something that got left un omitted.
Config was using 7i92 with spetpgens only and an encoder on each port. Everything is Ok and the new config starts and works after omitting said two lines.
The issue is with remembering the configuration setting from the tabs, plasma run and plasma config, those setings do not get saved no matter what. I did only change the ARCOK High and ARCOK low settings so far.
No errors are outputted to the terminal.
I think i read someone else had the same issue but i can not find the topic.
It also does not set the encoder mode to 1, i.e.
setp hm2_5i25.0.encoder.05.counter-mode 1

After some testing, it does save the cut amps but it does not save the cut volts in plasma run tab.
It does save float travel, but it does not save ok high, ok low, and voltage scale.

Tommy and Clive,

Saving Parameters:

• I tried from here and all seems OK.
• I then cloned the LinuxCNC repo and build LinuxCNC, ran Configurator and everything works fine.
• I definitely have no problems saving variables from the Config or Run Tabs.

EDIT: see here for a possible explanation.

Tool Change:

• It "should" comment out manual toolchange lines and provide toolchange passthrough
• Tom, could you post the <machine>.ini and <machine>.hal that the Configurator created and also the _original_foo.ini and _original_foo.hal backup copies it created.

Encoder Mode:

• The Configurator doesn't set encoder modes at this stage, it assumes that is already correct. (maybe in the future)

Of course i will as soon as i get to my workshop.
Thank you.

Config attached in full, ziped to the max.

Thanks Tom, I can see the tool change issue and hopefully I can push a fix today.

Any other issues?

Edit: A fix has been pushed for this issue.

I have a fix for saving parameters so you don't need to press enter for entries done by keyboard. Before I push it I have a question.

I have explicitly prevented Kerf Width from being saved but I cannot remember why I did that.

Can anyone think of a reason for that or shall I allow it to be saved as well?
