Here is the .ini file for my Gantry.
I think this should help you as a template.

Easiest way would be to add a breakout board like a 7I78, 7I85S, or the common Chinese (Sainsmart)
parallel port breakout. There is 7I96S firmware for all of these breakout boards.

You can use a switch to run up to 4 Mesa Ethernet cards at once, This is better with  hal changes so that
the read times are overlapped instead of added.

Normal hal addf layout would be something like:

addf read0
addr read1
[ bunch of processing addfs]
addf write0
addf write1

But this means that the second read needs to wait for the first to complete before
starting, so to overlap the reads, you:

addf read-request0
addf read-request1
addf read0
addr read1
[ bunch of processing addfs]
addf write0
addf write1

 

 

Yes, I've tried both, neither surfaced the gvcp panel with gmoccapy.

YangYang found something to do OP real quick, maybe will have update tomorrow.

Hi bmoo, have you made any headway wiring your spindle?

It clearly states under point 6 that after switching to the battery encoder cable, a reference run must be performed again. After that, you can comment out the lines.
The internal CIA402homecomp should be used for this one-time reference run.

What do your configurations look like?

I have tried both. Setiing it as an XYYZ and as XYZY. copied joint_1 to the end of the ini and named it joint_3, for the XYZY. for the XYYZ i copied Joint_1 and pasted it between Joint_1 and Joint_2. renamed it as Joint_2 and renamed the original Joint_2 to Joint_3. both times with the same error with the limits of A Axis. when i delete the last joint it starts up as normal.

Good morning everyone. I would like to do more. I can make an image of my HD and put the image somewhere, made with Clonezilla or other software. Luca, I will contact you, so you can give me a link to support the image. While you have Debian 13, so you can try it on your system. In the meantime, today I will try your patch and try to scale the I/O peripheral, the last one on the bus, and if it still doesn't work, I will change PC.

I don't think that would help much without your slave  hardware. Its not just a simple config problem. The remote access is probably the best way.

You might be better making it a XYZY machine, then just copy down an extra joint in  the ini file and copying the joint setup in the hal file to a new joint 3 section which I basically a copy of your existing Y joint (joint 1 ?) Dont forget negative home sequences for your 2 Y joints.

Alternatively, I set up a new XYYZ machine in pncconf/stepconf very roughly ignore scaling etc, then cut and paste the accurate data you have to the right spots.
Anyway that's how I'd do it. I think the first option is probably easier.

I still use only one servo drive, set the position scaling, the maximum velocity of the system and I am experimenting with the homing.
Now I follow you guide about absolute encoders. I uncommented the rows for homing in the .ini and .hal files and added the missing PDOs for homing the .xml file.
By the way in your .ini file you have a homing settings that are not commented and below them you have commented home settings that are said to be only for homing. But if I uncomment them there will be duplicated home settings. Therefore I commented the first batch with home settings and ran LinuxCNC but the missing pins error appeared.

You could try an audio switch, or other high performance switch. I think though that the network card suggestion is the better route. Alternately, is there no breakout board to add something like a 7i78 to the 25pin expansion?

At what stage are you?

all you need to do is type
sudo apt-get install linuxcnc-uspace linuxcnc-uspace-dev

This will get you 2.94 which is  a couple of bug fixes behind the current 2.98 version

If you want to get to 2.98 (which is probably not a big issue  for now), follow the directions here
linuxcnc.org/docs/stable/html/getting-st...th_preempt_rt_kernel geometry dash breeze

Laptops are not good candidates for linuxCNC because of all the latency inducing features in them but its worth trying. If you do need a better PC, go to 2.98 then. Install with the ISO on the downloads page
linuxcnc.org/downloads/

I have a few installation videos on my @MrRodW YouTube channel
 

Thanks

Download just the publish .exe file from here 

codeberg.org/endian/twincat3_to_lcec_eth.../branch/main/publish

Thats all you need ... Export working config from the TC3, open .exe file, type c -i, hit enter key, drag and drop file to open console, hit enter.... It starts and it will search through root folder of twincat to find real DC configs and it exports the .xml config of master to lcec shape with every startup SDOs which are very important... I did this translator just and only for this feature + some user friendly and free interface too...
