By changes I mean adding a new file or deleting one. Actually didn't try modifying the content of an existing one.

I tried both mounting using mount and using fstab.

Any changes made directly on disk will be reflected instantly in the file browser both in debian and in probebasic. So when the folder is hosted on the machine, even as an smb or nfs share, it does work. It doesn't only when it is a remote share. Like, it works, but I have to manually refresh it to see the changes. Either by F5 command or by exiting and re-entering the folder. (which doesn't work well in probe basic).

This also why the syncthing workaround functions. Because a full copy of the folder is hosted on the machine.

I believe the problem is with the remote share notification protocol.

Sorry late answer... but yes looks like you got it.

Have you been able to accomplish this? I have an equipment like this as well and its using a ispLSI 1048E chip controlling an optical equipment and the legacy hardware has no software available from the manufacturer. I understand that through the RS232 a pc was used with a gui program sending commands and then it retrieving data on to the pc for plotting etc. So I cam trying to figure out how to look into the chip with the program and decipher the commands to create a new program to drive this unit. Maybe one of the softwares from the Lattice website can be used to extract and retrieve the software inside the chip etc. Please let me know if you had any success and what angle of approach you took

ahh don't sweat it . I have been a bit busy today doing research for the LCNC change over from GRBL.
PCW gave me a few Idea's to try out and I already have a basic profile on a 9020 optiplex. The
big thing will be setting the 7i96 to handle temp control of the hot wire.

I have built a cnc foam cutter with good success . As for the hot wire I have found Nichrome 80 wire 
works great see the below link for what should work for you.

Thinner usually works better but looses temp faster over longer distances and thus requires higher voltage. I tend to
stay between 22 to 26 gauge and use a 24 volt power supply .I am also  in the process of switching from GRBL to
LinuxCNC and have built a few different types of machines that use LCNC. I am also in the procces of integrating in
a 5th axis on my foam cutter you may find this thread helpful.

Aciera, Thanks for that, I can now see the halui stuff in HalShow

I think I'm pretty close, but need a little help troubleshooting please.

The configuration:
Axis connected to an Arduino board, the Arduino board has a couple of digital inputs(6,7) and a couple of digital outputs(8,9) that are linked to LinuxCNC via a python script. The Arduino/Python portion seems to be working just fine, I can trigger Arduino outputs with HAL file links and I can observe digital inputs to the Arduino in Hal Watch.

What I'm trying to do:  when I activate digital input 6 on the Arduino, I want Axis to jog X in the positive direction, (as if I mouse clicked the + "X")
What I have done:  I added the following to postgui.hal:
   net  jog-x-pos  halui.axis.x.plus
   net jog-x-pos  <= arduino.din.6

Arduino input 6 happens to be configured with a pullup, so when I push the button the input goes low, so I set the arduino.din.6-invert bit

What's happening:
When input 6 NOT pushed; arduino.din.6 is yellow (because it's pulled up), halui.axis.x.plus and jog-x-pos are both dark, so far so good
While input 6 IS pushed; arduino.din.6 is dark (it's now low), halui.axis.x.plus and jog-x-pos are both yellow, so far so good
However Axis does not jog. Estop is good, machine power is on, X is selected, just no movement and joint.0.kb-jog-active remains dark.
If I mouse click the actual + jog button in Axis, X moves and the joint.0.kb-jog-active watch LED briefly flashes yellow.
So for whatever reason my button press is not actually causing Axis to jog.
Please see attached, and thanks in advance for any guidance...
 

 

Made this a sticky so it is easier to find.
Thank you.

Well I'm not fan of windows either but I suppose you'll be happy to hear that the runtime of codesys can be executed on linux and twincat on bsd. I use the preempt-rt patch and a dedicated core to run ethercat. It's surprisingly good 1-7us jitter most of the time and nearly always under 100us.

Hello
What would be needed for Linuxcnc to do a height map and or points to cloud?
something like this >

It has probing options.....my machine is 5x10'

so let say I put a car hood and want it to probe at a set distance intervals ...what are the steps needed?
if I get the coordinates in txt file it would be sufficient for what I need.

Thank you!

Thanks for your help, I guess I could create a xml file in the format that I need though it is a little more difficult and I guess I'll find software to do it based on the info you've provided. If it works for you then the indexes must be correct.

I really hope the vendor gets back to me, as much as I'm a bit interested, I don't really want to spend time on this tbh. I hope all the info needed is in the file you have provided otherwise buying a different device would probably be wiser rather than trying to guess some default values added by the software you use which may or may not be in the documentation which is probably aimed at the user level.

Maybe I could ask how you arrived at the addresses for the pdo and sdo index and sub-index?

Some time you might be interested to see what the normal standards are and how they are used with Twincat and Codesys, both can run g-code and twincat is very advanced in that area.

thanks

The addresses I used came from the commands I quoted.
Yes what I did will work.
If you want to make it easier, use Beckhoff hardware as its well supported via single line entriesd in the xml file.

We don't need another motion controller that interprets gcode. We use Linuxcnc for that.
I have no interest in Windows anymore. I use Linux for everything now.

If the same drives are used, and the same motors, and if everything worked before, forget the power supply for now.
In the ini file, set acceleration to 100 for all axis, set the max velocity to 10 for all axis, do some tests.
Any improvement?

Typically the position loop ( position input, velocity output) will just have P and FF1
The velocity loop (torque output) is usually P,I but the FF term depends on whether
it has velocity in or position in (FF1 for velocity in, FF2 for position in) In the velocity loop
the feed forward terms are inertia dependent

On many of the Arduino based stuff they usually repurpose the spindle output for hot wire control.
