Some thoughts and some findings using PlasmaC

Hi, yesterday I updated the plasmac and cut several sheets, and there were no problems with the float-switch sensor triggering when the torch ignition.
So the update "disable ohmic and float fault sensing until arc ok" works fine.
Thanks Phill

I just got my plasmac machine up and running and seems to have tons of little bugs... mostly with torch starts now but I was having float switch issues.

Reading through this thread it seems most of my issues should be resolved with this update! Super new to Linux so I’m glad there is a large support base here to help newbies like me.

We got stuck at 0.180 !
For some reason the master build for Stretch and Buster is not happening since 27 of October .
Just did a post in the Moderator part of the forum, so should be OK soon.
BTW, the 2.8 official release is all good.

Ooops ! My bad.
Fixed it, thank you Rod.

Did some thinking today ..... (pause till the laughing subsides ) about the square tube cutter as i finally had about an hour of time to do nothing ... well think about how it should function and how the hardware is going to be set for what i need it to do, so while doing that i was thinking of how the gcode should look and work as this will be basically a 3 axis machine with the possibility of rotating the work piece so there are always 4 pieces of 2D cutting to do, or 4 XY planes. In this mode the A axis will do exclusively 0, 90, 180, and 270 degrees.
I'll try to use an example, i did say TRY:
-square tube 100x100mm
-need to cut it at 45 degree angle
===if everything is set up correctly regarding the X and A axis speeds, meaning the time it takes for X axis to move from 100mm to 0mm position should be the same as for the A axis to turn 90 degrees, so the move will go in unison with the torch following the tip of the tube.
-here is the gcode i came up with on short notice and did some tests in a sim and it seems to do just that: -More explaining or trying to:
-the machine should be looked from the front, tube pointing at you - "looking at the barrel of a gun", X moves perpendicular to tube, Y moves along the tube,
-machine at 0 torch should be on the left edge of the tube
-m3 = fire something, launch a missile, do some damage ...
-make a perpendicular line to the other edge of tube G1 X100 Y0
-move the torch back to 0 at the same time turning the tube 90 degrees, THC takes care of the change in height, on thin walled tubing might need raising the feed rate,
-now the machine is again at x0 y0
-move the torch to x100 y100 to do a 45 degree cut on the second XY plane
- move the torch back to 0 at the same time turning the tube 90 degrees
-now the machine is at X0Y100
-move the torch to X100 Y100 making a straight cut on the third XY plane
--machine again at x0 y100
-Move the torch to x100 y0 making a reverse 45 degree cut on the fourth plane.
Easy enough, although it took much more to write this down than to thing, power up the pc and watch some AMD Radeon 6800XT tests, make a sim config for 4 axis (there are none, i am pretty sure there was one in the early days), writing and rewriting the gcode and testing the Display section of Axis GUI to force it to show something useful, but no luck there, this is the best it could do:

Just gave it a shot at editing some python files and created another wizard for the conversational and ..... no go, need to recompile a pyc file.
Waiting for Phill's wrath to come down on me !

It "should" do that automatically.

I can have a look at it this afternoon (my time) if you want.

Nah, no worries, just needed some brain workout, given the load it got last few weeks, this is like a walk in the park !
I just need it to do the above explanation, or lack thereof. I can code that in gcode in about a minute, but if someone has the sudden urge to buy the machine, i will have to do something about it.
Thank you for everything.

Been using the machines a lot lately, so here are some more thoughts:
