Another plasma component...

I am cutting today and noticed a couple of potential problems. Please remember that I am running a version from the first week of the month.

1. When the float switch is activated during motion (torch dive from too long a lead out) everything stops as it should and the program enters the "Paused" condition as it should, The problem is even with the float switch cleared you cannot "Start" (come out of the "Paused" condition) again program state is stuck. Requires a full stop and run from line or code edit to recover.

2. When there is an ohmic probe active before probe height error (wet torch end) when the IHS skip is active everything stops as it should and the program enters the "Paused" state. The problem is that the IHS skip state is not deactivated when this happens and when you restart the program the torch goes to a random height and tries unsuccessfully to pierce, again the program state appears stuck and can only be fixed by stopping the machine and restarting.

While neither of these is a real show stopper for an experienced operator, they will cause newbies to pull out their hair in frustration. Rest assured if there is a corner condition I will eventually find it.

John,
Thanks for the report,
Item 1: I haven't noticed, I will check it out later today.
Item 2: I pushed a fix for IHS skip problems on 14th May, I will test for the condition you just described later today.

Cheers, Phill.

Thanks for all the hard work on this. I am sorry for the duplicate report. I am running in circles right now trying to keep up with production and outside employment. It is early summer here now and the yard work is crazy. Hard rain every 5 to 7 days and night time temps 10-13 means everything is growing wild. Lawn must be mowed every 5 days. We have about 16+ hours of daylight right now.

John,

We are the opposite here, heading into winter and hiding indoors.
I have just finished testing those issues (on a sim config) and they both seem to be fixed...

Cheers, Phill.

I have pushed some updates.

Changes to plasmac.comp so you need to run make.
A change to the kerf crossing calculations for anyone who is game to try it...

Some minor changes to:
configs/by_machine/plasmac/axis/metric_plasmac.ini
configs/by_machine/plasmac/axis/imperial_plasmac.ini
configs/by_machine/plasmac/test/plasmac_test.py
nc_files/plasmac/imperial_wrench.ngc

Cheers, Phill

You know you live at the wrong end of Australia Phill, I'm still in short sleeve T-shirts here. Fortunately the grass is growing slower though. I mad the mistake of doing a massive back yard makeover which includes a lot of lawn and pop up sprinklers a couple of years ago so I feel for John becasue I chose a slow growing grass variety!
