Building a chain driven Plasma table.

At the moment I don’t have a Linux machine available. Only a MacBook M1.

But I will definitely try it when I get home. It looks like a promising project.

I just tried viacomstructor.
It seems to generate Gcode that can run on a qtplasmac sim configuration.

However it looks like it does not generate lead ins that I selected under leads. Is there something I do wrong?

I just realized. I have to select the starting points manually then it adds the lead ins etc.

So basically it looks like it does what I am looking for. 

The biggest limitation is my lack of understanding all the functions of the software.

Are there any help files or tutorials for viaconstructor?

  So far the building of the machine was all much easier than I expected.
But welding the water table is a big challenge.
Since I could not find a peace of sheet metal l large enough it is all warping up. And as it is now it is not usable. I would appreciate any advice on how to get those sheets straight again.

 

I must say viaconstructor works quite well for plasma. Only thing you have to do is choose laser cutter under machine and set the tool with.
I cut some complicated shapes like an Elephant.

However on one file a single shape I could not choose a starting point. Is there a bug with the software.

However I found an easy work around I just rotated the part and moved tho cut on a different part of the metal sheet.

  I got the water tray into an acceptable condition.
I removed the problem welds and
welded some slats underneath to straighten things out. (The sheets had a radius when they came back from bending)
Then I re welded them..

Next time I would cut them in such a way that seems will be shorter and all in the same direction. I hope this post will help some others hobby welders avoid the same problems.

   I keep getting the following error message on startup of Linuxcnc.Is there something I need to change on the configuration?

That means the host computer has a latency issue of some kind

Common causes:

Power management/speed-step/Turbo modes/C states >C1 enabled in BIOS

Network hardware issues with Ethernet connected cards

With Intel MACs you need to disable IRQ coalescing (man hm2_eth)

With Realtek MACs and the LinuxCNC buster release you may need to install
the DKMS RTK8168 driver as the driver included with the shipped kernel is broken
 

Thanks for the info.
Mine is an Intel MacBook 2012

Could you point me to some info on how to disable IRQ?
