I wouldn’t trust Windows anything to pour a glass of water.
But if you must, there has been a changer in one of the vnc apps, can’t remember which, which doesn’t allow a user to login remotely as well as locally. Linuxcnc is just Debian under the hood, nothing special other than Linuxcnc being installed. So any tutorials for Debian bookworm on vnc will be fine (the platform won’t matter). Since the linuxcnc images aren’t based on the Raspbian images any tutorials for the RPI5 using the Raspbian images will not be
what you want.
But before you do anything ensure you have a physical estop if you insist on vnc, cos if you lose your connection you’ve lost control of the machine.

i am using dimitry's sscnet card to control the servos and just a few mesa cards for all the rest of the IO

That is interesting, if I recall correctly the SSCNET card needs a 222us cycle time. I've always wondered if Mesa hardware could be run in parallel since the IO options are quite limited otherwise.
What interface are you using for the Mesa cards, PCI or Ethernet?

Yeah I’d agree with Ollie, if you just want a DRO there are better options that give more functions.
And from what I remember and how I did it, the Touch DRO circuit is easy enough to build up on some vero board.
Vevor au has a 3 axis kit for about $110 and a 2 axis kit for just under $100 and that includes scales and the head unit. For that price I wouldn’t mess around with a RPi and Linuxcnc, and also mate you’re really gunna think how many beer tokens you’ve spent trying to save money.

And in all honestly it’s not all that difficult to operate a lathe without a DRO.

Hey guys

just a quick update here.

we worked out the original diagrams of the machine and connected up a lot of  the hydraulics to allow basic operation of the machine

first we connected up the hydraulic pump and checked it was rotating the correct direction.  for those that don't know if a three phase motor is going backwards just swap any 2 of the 3 wires and it will reverse

so we swapped the 2 wires on the main line in and then repowered up the machine

halcmd -fk is your friend here

just type it into the terminal  and then you get auto complete of all the loaded pins on the machine and signals etc.  It is a seriously awesome tool

just to be crystal clear.  "quote marks" mean that this is a Hal command

also i am guessing at the actual pin names just to be clear they are probably not correct..

so the command "setp" turns a pin on or off
 setp hm2-7i92.0.7i77.output.00 1  (this will turn the first output on the mesa 7i77 card which will turn a relay on which will then turn on my hydraulic part.

we did this for all the hydraulics and got to a stage where we could remove the tool in spindle
spindle is hydraulic which is nice and easy

next plan of attack was to get the pallet changer going

current status is all hydraulics are working.  just need to get the motor working to rotate the pallets and swap them and it should be working

I will code a few things in classic ladder just to make it automatic.  and then i need to go through and setup timouts just in case there are other issues and i am not watching.

and thats it for now

hopefully next week i get more time to work on it and get some videos going etc

cheers

Hi, I have tried installing tightvnc and realvnc but iam unable to access the remote desktop of linuxcnc in my windows system. I have installled tightvnc sofware in windows 11 iam getting blank screen. Can anybody can tell me the VNC which supports Linuxcnc ?.

Thanks !

i have a very cheap Caliper with digital readout like this:
ideaengineering.us/?ec_store=pageid1904m...er100-700-06-dro-kit

that's on my to-do list, to read them out and integrate them into RIO

it would be nice to support all kinds of 'RS-422 (differential) and TTL (single-ended) glass and magnetic DRO scales' things but i have no to try it.

if you have this:
store.touchdro.com/products/touchdro-dro-adapter-kit
i think it is easy to attach a display to the esp32 if you only want to see the measured values.

this scales seem to have an A/B output like a rotary encoder, which could even work directly on RIO,
but unfortunately I can't test it
www.vevor.de/lineare-skalierung-c_10122/...scale-p_010550861161

i think there are cheaper and simpler options when it comes to just displaying the values, i don't think RIO is worth it for that

 

i just pushed all of the changes to use C for the 5th axis, if you are installed with apt using the very latest you should be able to run an apt update and have the latest version that should give you what you need!

Awesome work!

I gotta ask...store.touchdro.com/... it's really expensive for what it is and the shipping cost is wild.  But I want something like it...

So can I get funky DRO functionality (not the Android app stuff) with RIO, like it would be cool to plug my lathe and mill machines SINO glass scales into RIO and also have local multi-segment displays beside each machine and a headless Pi somewhere...?

What GUI are you using (Axis, Gmoccapy, QtDragon ...)?

My machine is xyzac, the a-axis rotates around the x-axis, the c-axis rotates around the z-axis, and the Probe Basic is xyzab
 
 

The machine has position feedback through Heidenhain glass scales and a 3 axis module with a single output cable

Not sure what you mean with '3 axis module' but the signals from the glass scales may need to be converted from analog to digital signals using Heidenhains 'EXE' modules. Some people have also built their own converters. Or you could also replace the scales of course. Have a look for type plates on the glass scales to be sure.

Good question, I will take a look tomorrow,  but I think it's just a matter of changing the dro and jog button axis designator in the ui, and adjusting the offsets table display option in the custom config yml file.  And of course your ini setup for the correct machine configuration.  I haven't built a 5th axis yet so it got backburnered and forgotten. /o\

Machine coordinates are always defined with respect to tool movement on the workpiece regardless if it's the spindle or the workpiece that moves. So presuming that the blue coordinate system represents the tool movement on the workpiece then that is a common setup for a mill. Having the X axis pointing to the left in the CAD system is not wrong (you just have to rotate the part on the machine table) but a bit unusual.

[edit]
Nevermind, seems @Lcvette got it.

ihr deutsch ist schon gut wenn es nicht aus google kommt sogar sehr gut für eine beginner

jetzt läuft die 5i25 und 7i76 kombi ja

ich warte ab und lege einen reserveplan auf danke für die hilfe die anderen karten muss ich mir erst ansehen
