Ethernet connection to Mesa 7i76e disconnecting on its own after one minute

Category: Plasmac

OK a 8300 USDT uses Intel hardware and should be fine

Is AMT disabled in the BIOS?

Ethernet connection to Mesa 7i76e disconnecting on its own after one minute

Category: Plasmac

So some background information my plasma table electronics and mesa 7i76e are not new the PC is new a newer HP elite 8300 USDT I swapped it out recently following issues with this post forum.linuxcnc.org/plasmac/53087-qtplasm...e-0-in-middle-of-cut

Retrofitting an old industrial CNC mill with EtherCAT components - MAHO MH400E

Category: EtherCAT

how cool is that! great work! that opens a huge door for older Heidenhain scales to ethercat without the need of exe's. thank you very much!

please help five Axis with Vismach simulation and Mesa 7i96S

Category: General LinuxCNC Questions

you will need to connect the joint position hal pin to the respective vismach hal pin.
This can be done in either the INI or a hal file.
For an example see
github.com/LinuxCNC/linuxcnc/blob/master...ilting/xyzac-trt.ini
# vismach xyzac-trt-gui items
HALCMD = loadusr -W xyzac-trt-gui
HALCMD = net  :table-x      joint.0.pos-fb             xyzac-trt-gui.table-x
HALCMD = net  :saddle-y     joint.1.pos-fb             xyzac-trt-gui.saddle-y
HALCMD = net  :spindle-z    joint.2.pos-fb             xyzac-trt-gui.spindle-z
HALCMD = net  :tilt-a       joint.3.pos-fb             xyzac-trt-gui.tilt-a
HALCMD = net  :rotate-c     joint.4.pos-fb             xyzac-trt-gui.rotate-c

Retrofitting an old industrial CNC mill with EtherCAT components - MAHO MH400E

Category: EtherCAT

I do actually like the way the spindle encoder is mounted. Unfortunately, I already sourced a SICK absolute multiturn SSI encoder ATM60-A4A 13x13 bit a long time ago and only paid 65 EUR for it - or I'm going to use my leftover Baumer OG73 S SN1024 1V_pp encoder, which I received as a gift a long time ago. In case neither implementation works out as it should, I'll have a detailed look at your encoder :D ( AliExpress Link )

Back to the modified EL5021 terminal: I couldn't believe that it was that easy to modify it and be able to read the encoders back. That's when - as any sane person would do xD - I got into the car, drove to my parents' house, and tested the modified terminal on the Maho CNC mill. What can I say, it's working like a charm, even on the first try :o So, yes, an EL5021 Beckhoff terminal can actually read 11µA_pp signals and you only have to modify 9 resistors in total. A rudimentary schematic is attached :) I'm not able to measure the capacitance of the capacitors due to the installed resistors within the circuit, but their values shouldn't really matter (maybe an RC low-pass filter is no longer tuned as it should be, but that shouldn't cause problems here - I hope). I documented the very first test of the modified terminal and uploaded the video to YouTube.

I've also attached a screenshot of the CiA Danfoss VFD diagnostic tool for anyone interested :)

TTL to differential converter (STEP / DIR / ENABLE)

Category: Computers and Hardware

For testing purposes with just a parallel port, you could use 2 pins for one signal and invert one in hal
to get differential signals.

As long as the output bits come from the same physical port (say PP pins 2..9),  and the hal addf
order and thread is correct. the outputs will change simultaneously.

The reason ethtool is not found is that it's installed in /usr/sbin/
and that's not on the default user path. (but is in the default root path)

Thank you, but I have to modify the ini and hal file....?
I tried it with KI, but not working...

Awesome work Patrick!
Regarding the spindle, here is my solution for a similar setup, the idea was to be able to keep the drilling operation possible. It works well
