Here is how I did it.

TLDR; Disconnect the ground lead in the plasma torch cable. Measure voltage between material ground and torch tip.

Hi all

i bought a cheap plasma  Herocut Cut55i and i have machine plasma torch IPTM-80 like this
 
 

i try to do ohmic Hypersensing with a MESA THCAD-10 on my cnc table

Can you explain how physicali connect ohmic sensor?

Can i do ohmic ring something like that to the copper shield
 

or it is impossible on this type of torch and all that remains is floating switch?

thank you


 

Hallo Zusammen,
Ich les mal mit, will von einer Eding CNC760 auf Ethercat und LinuxCNC umsteigen….
Ich will in Zukunft 1KW Delta Servos und eine 11KW Delta M300 FU verwenden, alles mit t
Ethercat Schnittstelle. Den Buskoppler hab ich heute bestellt ebenso ein paar DI und DO Karten….

-1mm might not be enough to move off of the switch so try -2 or -3.
If it still does not work, try 2 or 3.
Also, hoome sequence should be 0 for Z axis so it moves up before other joins/axis start homing.

 You can check the irqmask ( and grub setup) with this script



usage

first

chmod + checkmask,txt

then

./checkmask.txt  [ethernet_device_name]


You can pin  the Ethernet IRQ to the last processor with this script


 

usage

first

chmod + pinirq,txt

then

sudo ./pinirq.txt  [ethernet_device_name]

To disable irq coalescing temporarily for testing:

sudo ethtool -C [ethernet_device_name]  rx-usecs 0

To permanently disable IRQ coalescing, you setup the RT ethernet interface in the interfaces file, something like:

auto eth0
iface eth0 inet static
address 10.10.10.1
hardware−irq−coalesce−rx−usecs 0





 

Any Idea why my Z Axis won´t home anymore? I changed the negative travel distance. But before i noticed that i can´t change some values anymore -> see attached file

Thatś it. Thanks

Here you are...

Yes, but only for the network Mesa is attached to.

It is the included one yes. So you say I must select the option of "Use this connection ..."

Has anyone used the io pins on the drives as io pins in linuxcnc?

Tommy I usually make use of nmtui or the network manager

Is that the included Network Manager ?
If yes, then make sure the below is selected:

Final home position from 0 to -3

please share your hal and ini files

Hi,
i get the "Joint 2 on limit switch error". I have a Mesa 7i76e and you can find my configuration for Joint 2 attached. 
I tried several things but still with no success.
Please help
