Hello Senior Members,

I have begun working on my 2nd linuxcnc project. Previously, i have successfully set up 2 CNC machines with Linuxcnc and parallel port combined with a lot of help and learnings even for the most basic things from you all.

This time i have:
> Rpi 5, installed with LinuxCNC 2.9.4  Raspberry Pi 5 OS based on Debian Bookworm  Raspberry Pi 5 on a SD card through Raspberry pi imager.
> Mesa 7i96 board (fresh out of the box, w5 and w6 jumpers set on Down position)

I have read through forum.linuxcnc.org/9-installing-linuxcnc...l-images-only#320270 and rest of the topics, hm2_eth , network manager, and youtube videos. I am still unsure what to do and how.

> i cannot make a wifi connection with menu-config. i dont really understand it to be honest. what information to put and where?
> i cannot edit the etc/network/interfaces file, it does not let me save the changes. and what shall i change and not change in it?
> with network-manager-gnome im still not able to connect to a wifi or ethernet. also what is eth0 and wifi0 they cant be used?
> what is mesaflash? do i have to flash my mesa card or update it or whatever during my first boot? or does it work out of the box

If only somebody could just walk me through the barebones setup so that i can simply make a connection to the mesa card, and have wifi connection too.. from scratch. it would be very helpful for me and anyone like me. 

Best regards
Sk

I had seen that yesterday tommylight. If you use solder paste that is specifically designed for syringes it probably
works well. If you use the regular solder paste you eventually push so much of the liquid flux out of it that the
paste starts becoming impossible to dispense. I have had that happen numerous times.

Hello Sebastjan, I haven't completely solved the problem yet, do you have the code?
How do you send it?

Hi there,
a friend convinced me to go the Ethercat way. I got A6-400W-Ethercat Servos.
I followed the "How to use A6 Servomotors Software" guide by OMC but after the "Auto-Tuning" my Servos or better to Say the Couplers are still movable by Hand. If i increase the gein when Tuning, it starts to play airhorn.

Could someone maybe advise me How to properly get started?

Your project is very interesting. Where did you get the spindle mount?

Hi All, 

Just working on finishing up a 5/6 axis router build and I'm trying to wrap my head around homing the C axis on the head.  I'm aiming to have 720deg of rotation, maybe more.  What I'd like to do is automatically unwind the head during homing, so I don't wind up the cables over time.  So the controller would store the last position (it's really difficult to back drive so I'm not worried about it moving much while the machine is off),  then move in the the correct direction to get back to 0deg (not just the shortest way) and then start the homing process using a switch and encoder index pulse ,this part is no problem.  I had a few ideas on how to accomplish this, but I was wondering if there's some easy solution I'm overlooking.   

Hallo, wie muss ich einen AC Servo Drive HL-T3D-L20A-RABF mit 750 Watt Servo MotorAn einen Mesa 7i96s anschließen. 

It is 2.9.4, rpi5 with 7c81. I think is not related to spindle, even probe program don't want work.

You are kind of out of the ethercat swamp now. It's now all linuxcnc and hal
to set up the spindle.
You will need to know what the spindle expects as input (read the manual)
and what input you need to give to the ethercat unit to produce that (read that manual).

The example here uses the pwmgen component, ethercat does that now so you won't need that.
linuxcnc.org/docs/html/examples/spindle.html
You have the speed in spindle.0.speed-out, you should connect that to the duty cycle but you almost certainly
need to scale the rpms to the duty cycle number. Check example 1 in the doc above how to use the scale component
for that. So you will have the spindle rpm going in to the scale component and the output from
the scale component going to the lcec.0.0.DUTY-OUT-0 pin.

Set the frequency to the spindle's preferred frequency like 1500 (don't know, check manual)if that pin is for the frequency.
