Hi Meister,

I have setup a board file and config for the Terasic DECA max10 board and connected a W5500 module but it isn't showing up with the correct ip address.

I can confirm that the board is flashing (I'm using the quarts programmer to flash) as the LEDs change when I add or remove a bitout plugin.

The SPI clock and chip select looks right and signals are showing up on my scope on both mosi and miso lines (I don't have a digital decoder so can't interrogate the codes themselves).

The w5500 is showing up as a network device with what seems to be 5 default addresses (when I use arp -a in CMD)

Any thoughts on why the W5500 isn't configuring with the 192.168.10.194 address? I can share my board and config files and the compile output if that helps.

Thankyou!

I think Beckhoff and Rexroth have a distributed Ethercat drive system where the drive is built into the servo and there is only one power and data cable.  I've never used them and I'm sure they are pricey.  If you use quality cabling I don't think the length will be a problem.   You could also mount an EK1100 on the carriage and/or the far end to locally terminate signals to Ethercat vs running them individually back.

I would suggest connecting the limit switches and linear scales directly to the servo drive...I think you will get the best closed-loop performance by letting the drive handle it all.  If you are going to all this trouble I would also be sure and get absolute encoders so you don't have to deal with homing on this large a machine.

Hey Eduard,
Thanks for all the effort... do you mind sharing your configfiles? xml and hal?

this would be great!

Thank you

Cheers Einar

Awesome!

What are those magic display buttons? Link?

I’ve mainly worked on much smaller machines, so on a lathe this size, I’m not sure whether the long motor/encoder cables would become an issue. If it's okay to leave the drives in a central cabinet and just rely on good shielding and routing, I’m happy to do the same—this is more of a concern than a hard opinion.

EtherCAT still appeals because it lets me pull extra data from every drive (load torque, temperatures, alarms, second encoders), and keeps future expansions simple.

Suggestion / request:
Overrides
When starting a program running (cycle start): user is prompted that an override (rapid, feed, or spindle) and asked whether they want to continue with override, or want to reset to 100%

(I make the mistake of setting an override and then moving onto a new program and hitting start, forgetting about the override)

Vast majority of servo / servo drives have "normal" cabling between the servo and the servo drive.

Don't see any difference due to ethercat just because one axis is 7m long?

(I'm a fan of ethercat and think it is the way forward. So neat just plugging servo drive into linuxcnc with single ethernet cable and getting.servo drives status / encoder position etc)

Thanks for catching that: the machine is X + Z plus a spindle.

There’s no VFD at all—this is still a fully manual lathe with a star-delta spindle and gearbox.

I picked EtherCAT mainly because the bed is 7 m long and I don’t want voltage drop or noise on long analogue/encoder runs. One Cat-5e solves the length and loss issues.

Would it be possible to add a confirmation dialog box prompting the user before initiating another homing cycle .

You mean when the machine is already homed?

When I run the program and want to pause it midway through the G-code execution to clean the machine from chips, it doesn't allow me to manually move the axis.
I believe the program should allow pausing, during which I should be able to manually move or return the axis. When I choose to resume the program, the machine should automatically return to the position it was in before the pause and continue execution from that point.

Also, if I stop the spindle and start it again, the speed is much lower than before.

That is not part of the GUI and not supported yet. For that you need to switch the mode and that would stop the program execution. It would be also a bit complicated, remember if you are in the middle of an arc or just in the middle of a line. etc...

But the spindle should resume at the same speed. Can you give an exmple to reproduce that?

A bit unusual use case though, but I agree that should not abort the program.

@besriworld

Many users asked already for the option to move the machine during pause. That feature must be implemented deep into LinuxCNC IMHO motion control, but not in the GUI part.

It might be possible to make a custom code and put that in between forward and backward kinematics to move i.e. the Z axis.

It is not supported yet.. is not the same thing raster engraving that has constant speed synchronized with accurate laser pulses.
In base thread yes supported but not in servo thread with mesa 

If you can modify the ini file you can modify the port address in the ini file.
Usually with any errors starting, the error log and ini & hal files are posted by he user.

It started when i was editing the .ini for a homing issue. After the restart , EMC2 would always terminate with an error. Somehow it modified the port address , from what i can figure. but with the system password unknown . I cant edit the port address.

Ill give it a try. Thank You for the step by step.

Good evening gentleman,
I am almost done with my new setup (printnc "pro", mesa 7i76eu, probe basic, jianken ATC) and everything seems to be working now, except the tool length measurement.
When I start a measurement with G38.2.... and then press the toolsetter with a finger (just to test it), the system errors out with "probe tripped during non-probe movement".
So it recognizes that the toolsetter is triggered, but for some reason it thinks its the 3d probe...  

This is how my probe and tls signals are linked:

# --- PROBE-IN ---
net probe-in     <=  hm2_7i76e.0.7i76.0.0.input-08
# --- TLS-Normal-IN ---
net tls-in       <=  hm2_7i76e.0.7i76.0.0.input-09-not

addf or.probeortls servo-thread
net probe-in or.probeortls.in0
net tls-in or.probeortls.in1
net probe-tool or.probeortls.out
net probe-tool motion.probe-input

What am I doing wrong ?

Here is my full config...
