Can you post your current hal/ini files that exhibit that behaviour?

Still sounds like a basic hal file issue

Custom homing - distance coded glass scales

Category: Advanced Configuration

I got it working with help of a coder brother and vscode agent by editing mwinterm 's homing files. There were several problems at start which caused inaccuracies in both encoder latched position and home position calculation but now it looks to be accurate. I uploaded quick video of the startup and homing if anyone is interested: www.youtube.com/shorts/St_XhQs68xQ . I also added some nice features;
-the machine offsets are stored within every 2 seconds and those offsets are used as machine offsets at startup before homing, so its kinda like absolute encoders but of course need to be homed to verify position
-custom .py -file checks soft limits before homing and aborts if current position is too close to limit
-also managed to remove homing final move, so minimal amount of movements in homing.

I'm considering if I should share the changed files or not, they are so machine specific. Maybe later when I find out if it's reliable and safe.

Regards
Ossi

So when we input a jog increment of .1in, the DRO will show a .1 in change and the motor will start moving but won’t stop. If we input an additional .1 in increment in the same direction the motor will speed up and the DRO will show a change of .2 in from the start. If we then input a .1 inch increment in the other direction the motor will slow down and the DRO will show a .1 inch change from the start. 

We don’t currently get any joint following errors.

[code]The addresses are missing in the pdos, which is apparently why the errors occur.
However, the addresses are found in the sdos.

I don't know if they need to be configured manually. What does the manual say?

Probe Basic DRO display appears blank

Category: QtPyVCP

Hello,

I recently upgraded LinuxCNC from version 2.9.4 to 2.9.8 and updated Probe Basic to the latest version as well. I'm currently experiencing an issue where the DRO display in the Probe Basic GUI appears blank.

Has anyone encountered this before and could point me in the right direction to find a fix? The Probe Basic simulation configuration works fine and the DRO is visible there, which leads me to believe my configuration file is the main culprit. That said, this same configuration worked without issues prior to the update.

I've attached the machine HAL and INI files in case they're helpful.

I shoukd have mentioned but the signal for the servos is +-15V, is there a good work aroud to up the V or something

Category: General LinuxCNC Questions

Mesa 7i96S for step/dir controlled drives (also known as "position" mode drives, almost all new servo drives can use this)
Mesa 7i95T same thing with added encoder feedback or glass scales if the mill already has them
Mesa 7i97T for analog +-10V drives, older drives and some new ones (also known as "velocity" mode drives, motors have a tacho generator wired to drive)
And many other combos that can do the same thing, mainly due to availability as last two are hard to find.

Im working on an old kondia fv-1 mill thats got an outdated cnc system, my plan is to hook the motors stright into a Linuxcnc set up and get rid of the old computer. Iv got 3 servo drivers to give signal too and have been trying to find a mesa card that can do that, im guess im under the wrong impression on whats its doing but iv seen a lot of 2-3 card set ups, im looking for a way to simply plug the servo drivers into a card that sends them a singal with the pc. Do i need that FPGA plus motion control card? Or can i just get by with one od the FPGA cards? Again im probobly confused on what thees cards are actually doing, iv mainly messed with old 3d printers, any explanations would be appreciated

Last night i checked you user name, all seem OK, so i am baffled at why you can reply to some and can not on some other topics...
Can you take screenshots of when you can and you can not reply and upload them here?

How do you know that the vid and pid are wrong? I have set them in the .xml file as per the manufacturer .xml when I created the configuration. Attached is the .xml file.

The "dmesg | grep ethercat" still does not seem to work, I executed the command sequence you posted and it just outputs a new row in the terminal.

I am still unaware why the synchronization error keeps appearing, cables are changed and I also have grounding on the metal parts of the bench.

Perhaps, there are some settings in the servo itself that need to be configured. I still think about the fixed and variable PDO mapping, if it could be the reason for this behaviour. There is a warning that says - 1 datagram UNMATCHED!.

When you say the motor moves, are you saying the DRO is changing
when no commanded motion is requested?

Do you get a following error?
