@Rod,

For your previous post 29 of may post nr. 135227.
My advise for you is to use the code snipped ( on circles and small shapes ) to lower your speed
to 50-70%. Sheetcam lines will turn from green to blue where the code snipped is active.
This will result in more accurate holes and small shapes. At the moment you go to fast i see at the picture.

The post after this 29 May 2019 08:39, i marked up your plate allignment of plasma cutting is wrong in relation to the working table.
Always try to cut the long pieces the other way. Try alway's to cut the long pieces over the metal strips 90 degrees.
See this as your nesting protocol !
And in the end. Why don't you have a water table? This will end in a much more accurate product.
I made my second plasma rotary water cut option this week for a Belgium customer. Will give the forum picture coming day's.

Thanks for the advice. It makes sense. I stopped playing with Sheetcam rules when I started with plasmac becasue I wanted to use it in its standard form and it does not have a way to disable the THC from Gcode but I think now I can depend on its corner lock to do that. I still have much to do to to finish off my machine and I know I can't put it off any longer.

Has anyone else had the float sensor problem where you can’t restart. We have been cutting steel the last 3 days and I think I have narrowed it down to when it happens. If the float trips during cutting (I have a VERY sensitive float switch under .005”) I can restart. Or if I pause during cutting I can restart. Where the problem crops up is right at the end of a cut. If the sheet pops up right as it finishes and bumps the shield it trips out and I can’t restart it. We cut recycled bandsaw blades up into smaller sheets for resale so the blades do move a bit during cutting. I had one today bow up almost at a 45° and the THC fallowed it perfectly.

So is there any solution to the float switch issue or should I just disconnect it. I do like the float switch becaus it dont have a break away torch and any bump will stop the machine.

you could use the relay of the torch on command to disable the float switch .. practically make sure that with the torch turned on it doesn't work anymore.

I saw the missing color button issue. But in my case, it depends on gtk theme: so with some themes(usually xfce default one) everything works fine, but another i see no color at all.
I tested it on debian 7 and mint 19

Please find attached requested files. I tried to set the theme to follow system with no change.

John,

If you get a spare minute could you try this:
comment out line 203 in plasmac_buttons.py which is "self.set_theme()" and see if that has any effect.

Cheers, Phill.

Edit:
Does the button have no color at all or is it stuck on one color?

No change Phil. The buttons have the default background colour in all states
