I have a few stepper motor CNC routers running LCNC and just got my hands on a Republic-Lagun VBM-1000 with a wonky Anilam 5000M controller that may need replacing if I'm unable to cost effectively fix it. As this is my first foray into servos, I'm looking for advice. The mill is driven by brushed DC servos. The electrical cabinet is all Anilam, including the servo amplifiers. I'm driving the steppers on my CNC routers with Mesa 7i96's and would like to stay with Mesa, unless you all have other ideas. Please lay them on me!

You commits caused somewhat of an issue. Do you think I sat on my hands and did SFA ?

I don't care about your workflow, it's not my issue. My issue was ensuring the integrity of the images.
I don't care about you trying to setup a remote desktop, that was something you decided to do. That software was outside the scope of the software needed to run a cnc machine. I don't know why people ignore using ssh.

Good afternoon.
Thank you! Everything worked out for me.
I had to try different encoding options.

I am planning  the exact same install for a 4th axis on a Bridgeport VX2T that I am re-controlling. 
Did you find or test to find the signals for the servo amp?  Any help would be appreciated. 

Ah.. gotcha

I have worked out why I have this message: when Raspbian prompted for system update, I accepted it. This over-wrote the RT kernel!

The kernel was reversed to the PREEMPT one. I thought it was something to do with how I built LinuxCNC ( I followed the official instructions to the letter ). So yesterday, I uninstalled LinuxCNC from my backup card, downloaded a installed the LinuxCNC *.deb 2.9.4.

I got PnCConf  to tune the X-axis... I updated the system when prompted. And this message appeared again.
 

Moin TooTall18T! danke für den Hinweis! Das wäre super klasse, denn ich weiß dass ich diesen Regeler noch brauchen werde. Ich probier das morgen direkt mal aus. Hatte mir die neueste develop Version von Dir geladen und installiert, da habe ich auch noch Fragen zu. Aber eins nach dem anderen.
Ich melde mich dann noch. Danke erst einmal!

Solution Found! Even though my main internal hard drive was successfully installing debian12, debian13, linuxcnc/debian12, mint, etc. the reboot to the new OS would fail with “no boot device found” It turns out that booting to a root starting point is much more difficult for a HD than going through the whole installation processes. The disk past the first BIOS test but failed the “short test” I got another HDD that did pass the shot test in the BIOS system check. Debian13 now boots with all green “OK” from a check list that runs at boot up (and shut down) all the way to it’s login then desktop.

Thanks Rodw, you pegged the problem from the beginning. I will get an internal SSD to replace my HDD as you suggested. I learned…

“typical HDD speeds ranging from 30-150 MB/s while SSDs can reach speeds between 500 MB/s and 3,500 MB/s or more “

The LinuxCNC was not pre-loaded, and the…

sudo apt update
and
sudo apt install linuxcnc-uspace linuxcnc-uspace-dev

Were not allowed in any of the 4 terminal options under system tools. The sudo command fails because when it asked for my password, it would not accept any input. The cursor did not move and no “******” to hide input were created.

[sudo] password for “username”:

The return or response after typing in the correct password anyway was…

“username” is not in the sudoers file,

Anybody know why this is happening?

That seems to have been it. Thank you so much!

Yes vendor kernel is preempt-rt, jitter stays under 10us especially when you don't watch youtube

Here you can find the result and download link:

Can you post the files or scans of the docs somewhere?

More info
How is the wire break sensor included in LinuxCNC?
Is that a normal hi/low signal that LinuxCNC sees?
If yes, wiring that signal to amplifier fault in hal would disable the machine, not e-stop, so you can change the wire and continue working.
You can also wire it to feed hold or motion inhibit, but both will just stop motion and wait while the drives will remain enabled, actually this might be better if the machine has something that can move when motors are disabled.

Hello, 

During the initial setup and test adjustments I performed before the final assembly, the probe function was working correctly. Since I completed the final adjustments, particularly the connection and calibration of the encoders, the probe no longer works. Instead of moving down, it moves up until it reaches the home position.

My Z-axis has a large travel range, which is why I set a HOME_OFFSET of 100mm to position the torch closer to the table. Manual jogging is in the correct direction, and homing also works properly.

All the travel parameters were the same as those in the attached file when it was working, only INPUT_SCALE and OUTPUT_SCALE have changed.

Do you have any idea what could be causing this issue?

 

Hello,

The forum I often browsed and for most problems I found help. Now, unfortunately, the issue has outgrown me. I have a plotter for cutting styrofoam with hot wire.
I need a wire break control in it. The wire is controlled by PWM. The problem is that I would like the control to take place only in a specific case, i.e. when the machine executes a program with (M3) on, the wire breakage would cause the machine to pause or e-stop. My control system works only when current flows through the wire then there is a high state on the sensor output. Can anyone help me solve this problem?
