i am sorry, it was some time ago. I believe that you can customize PDOs as you need.

A grounded steel enclosure is not the best place to be emitting radio signals from.

Nowadays just about any wifi dongle will work, but it will need an external antennae.

Should a good starting point for usable wifi adapters, anything that works with Debian Bookworm will work.

If you need extra help I'm located in Sydney as well.

Currently, this GPU is quite out of stock. In China, the price is approximately $40.

Hi all,

I'm just starting out with EtherCAT, and I'm trying to configure my Servo drives. Looking at some example configs, I often see dcconf and/or watchdog tags with varying parameters.

Would somebody be so kind to explain in simple words what those lines do? Are they mandatory or just for optimization? Where do I find the correct parameters for my drives (Hiwin ED1 400W)?

A link to a good documentation of those tags would probably also be fine, I didn't find good info yet...

Cheers,
Matthias

Steel, 400 x 600 x 190.
See attached (poor) photo showing RPi hanging in space:
Row 1: stepper drivers,
Row 2: RPi stacked on Mesa, I/O PSU,
Row 3: 12 Vdc relays, Mesa core PSU,
Row 4: Terminals,
Side: stepper sockets, hole for monitor+keyboard+mouse cables, GPO for monitor + RPi.
Terminals and cables as appropriate, much neater generally.

I have a virtually identical cubicle with some electrical equipment in it.
Stripping and testing should begin next week.

The RPi 4GB and L2.9.2 need to go back to their day job of cutting metal.

(SOLVED)

I compared V1.04 and V1.11 EEPROM Files.
And tried to understand configuration files.
I found my cnc configurations were mixed for V1.04 and V1.11.

Lichuan sales person said, we should use V1.11 with LinuxCNC for some reason.

Now servo lock is working by pressing PowerOn button.

Have a look at 'extra joints':
linuxcnc.org/docs/html/man/man9/motion.9.html

The maximum number of joints is 16.

Alrighty!

Drives and motors arrived. Setup a bench test rig. 

I've made it as far as getting the encoders to read in LCNC (scale seems right). Unfortunately I'm getting following errors when I try enabling the drive. I can hear the drive enable relay latch very briefly. 

I've followed Tommylights guide, but can't get too far when it errors straight out of the gate. Im also getting a "could not switch machine on, is limit switch activated". I currently have no IO assigned. 

I suspect my wiring is at fault or I'm really missing the mark with my initial PID numbers - I've tried a bunch so far, even with giant max f errors.
Schematic below. Any thoughts would be greatly appreciated!

Thanks,

So we have the 9 normal ones.....problem is I need 16axis total.
 

Found a machine that needs a new controller and peaked my interest on how would I do it..... It has 20ish stepper motors on it

It's a machining version of a progressive stamping die. Where 4 drills and a tap station are positioned into place via steppers than ran pneumatically after that. Thus most of the axis are used at the start of the program... after that they aren't used. These do have working homing switches. 


A saw, bar feeder, bar magazine, and prob the tap station are the things that need live axis/gcode control..... But none of the axis needs to be coordinated As everything fires (drill, tap, saw) then the bar feeder advances one station. 


The lame way would be to have 8 solenoids (3PDT) connect the step, direction, and home switch pins for each of those 4 drills (2 axis each), then home and position it. So all 8 axis could be "one axis" in software..... Seems complex.

Surely a software solution exists. Custom M code? 

Will use gcode for as much as possible but not opposed to Python or hal scripts. 


Thanks
