Hakan's EaserCat 3000?

I currently use a z probe routine that uses G38.2 to lower the tool into a metal puck until detecting continuity. This works 90% of the time, but there have been a few times this went wrong when either the wire to the puck had become damaged from use over time or the endmill had some plastic stuck to the tip or some resin from a wood cut, etc.

It seems much safer to manually drive the endmill down into the puck, then use G38.4 in the probe routine to move away from the puck. When I make this change and manually drive the endmill into the puck, I get a "Probe tripped during coordinate jog" error. Any ideas on how to avoid this error or how G38.4 is typically implemented?

Thanks!

Maybe you don't have a Intel MAC

lspci -nn | grep -i ethernet

Should list what you have.

Have you run a normal latency test?

 

Is it possible to do any useful testing of EtherCAT hardware with a virtual machine running Linuxcnc? 

I fully understand that Linuxcnc can't run with any realtime capabilities within a virtual machine.  But can an Ethercat configuration be set up, configured and connect to a real Ethercat device for testing purposes?  I don't want to set up and run a machine this way.  I would just like to see if I can read some IO modules, maybe configure/talk a drive and send it a command for bench testing.

What all could you expect this to do?  What things would be expected to not work at all?  What might sort of work?  Can Linuxcnc communicate with a Beckhoff PLC if so to what extent?
