I've never seen the sysv error before. 
Odd others have got the new method working already.
You need to use sudo for systemctl and journalctl. Can you redo and share?

Wow that just got expensive. This is a portable table, the cut dimensions are adjustable at the design stage and I am probably going to make mine 1000x800. The designer suggested a Nema 23 stepper kit with DM542 drivers and a Mach 3 controller from Aliexpress at about $235. I was hoping to use something like this probably with just a different break out board. Is this not possible? This is for hobby use and I am in QLD Australia if that makes any difference. This is also my first build, hopefully learn something and able to modify or make a MK2 at some stage.

I'm also  in Queensland also (Brisbane). You can find my email address on my @MrRodW YouTube channel. You can use a parallel port breakout board.I bought 2 off Amazon for $20. I might have a THCAD which you can use with the encoder component to read torch voltage for THC. If you went with Mach3, you'd probably need to get a Proma THC or similar so it will get expensive quick too. The DM542's should be fine. Very hard to kill. Geckos are way overrated.

At a guess, something has changed slightly with a home switch and its left triggered. Try editing your HOME_OFFSET on joint 1 in your ini  file and make it a bit bigger, maybe by 0.5 to 1.0 mm. This should move the sensor away a bit  more after homing. Ohh and check for anything loose.

Hello, good afternoon. Could someone help me load the .bin firmware onto the EC500 RT1052? I've tried several programs and commands, but without success. I have the Chinese Stlink V2 and a Raspberry Pi Pico.
 

The EC500 does not like programming and I have bricked two controllers some time ago.
Fortunatelly this is possibility to bring it back to life. 
I have developed the following procedure:
1. Disconnect the controller from the power supply.
2. Disconnect the programmer.
3. Short by jumper the BOOT_M0 pin with 3V3 (programming connector).
4. Turn on the 24V power supply and do not turn it off until the end.
5. Remove the jumper.
6 Connect the programmer (I use ST-Link, but others also work).
7. Run the script below: 8. If it doesn't work, keep trying until you succeed.  

In EC500 controller I have burned one output (+ or -) and can not drive one axis motor.
Which IC must I replace?

Over a year of flawless cutting, new issues today. 
It has been creeping in for a few weeks now. Occasionally, then every day, then ever cut, now every pierce. And now impossible to cut anything. 
Doing my head in why it appeared. 

Because I'm useless at linux and the cnc has no internet connection, getting anything on the computer is a mission. So, I have not updated linux in years. 

Any ideas? things that may have changed? 

Am I just overthinking this and just need to bump the debounce from 5 to 7?

What was the size of your largest NC file?
A few days ago, I made a mistake by putting a "-" in front of a value that was supposed to be positive in FreeCAD's CAM workbench, which resulted in an NC file that was 20,590 kB or 688,627 lines long.
The file was never run, since I caught the error.
So I was wondering—how large have the NC files you've generated been?

i have ds5c1 xinje, and i am having same trouble of getting the servo drive to OP. when i try to turn the drive to SAFEOP, the drive shows fault code e-817 any help setting it up?

Tried a fresh install from scratch and running in to an error during ethercat installation.

• LCNC ISO installed ok
• Updated realtek NIC driver OK - latency and network speed good, no issues.
• Followed first post in this thread, removed iGh repo
• Updated ethercat.conf via geany with MAC address of port (enp2S0)

got a failure starting start ethercat.service:

Can anyone interpret the error and help me with a path forward?

FWIW there's a balance between "cheap" and "not banging your head against the wall". Totally get not wanting to spend a ton on a first project before you even know if you'll stick with it, but going TOO cheap can be a self-fulfilling prophecy where the cheap parts make the build and end result miserable.

Where I 100% would NOT cut corners is the power supply for the steppers. Get a good one, ideally transformer-based (not DCDC/switch-mode). Steppers decelerating dump energy back into the PSU and can cause voltage spikes, especially with a DCDC supply with relatively small output caps (the transformer-based supplies already have large capacitors to keep the output relatively stable, so have fewer problems with this). If you do use a switch-mode supply, put a BIG capacitor on it, with a high voltage rating. I think I put a... 1000 uF/250V capacitor on mine after blowing up a driver board and a few "unkillable" GeckoDrive stepper drives. No issues after that.

Spending an extra $50 or something on a good PSU can save you hundreds in other killed electronics (not to mention time and sanity).

If absolutely nothing else, not getting the cheapest of the cheap-cheap no-name supplies is probably a good idea, just from a fire hazard perspective.

For circuit examination here the naked blue PCB. 
 

Ha, ich hab ne XS750.
 

I didn’t see that the instructions were changed. I’ll have a go at those on a new system. that one is being heavily used for testing now.
