Building a chain driven Plasma table.

  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?

The hm2_eth manual page has this information

man hm2_eth

Notes:

1. ethtool must be present (looks like it may be missing in the latest
LinuxCNC distribution so needs to be added)

2. This only applies to computers with Intel Ethernet hardware

 

I just installed ethtool.
Now there is no error message on startup.
