I already wired in another small 12v PSU, it powers something on the heidenhain impulseformer so I'm not sure if that would introduce noise into the encoder input but I do have buck converters as well now that you mention it.

I am Trying to set up a laser to align the work to the sheet in QTPlasmaC, however, it does not appear to be working properly. In the owners manual it says it should change to mark edge and then mark origin. it just changes to show it is turned on. What am I missing?

Hi all,recently my pc running version 2.8.2 broke down and i had to replace it and installed 2.9.
Thankfully I kept a copy of all my files, so that helped me out a lot.After a couple of hours i got my setup to work again.
The only thing that doesn't work is tool measurement.The option in the advanced settings tab keeps getting greyed out.The line in preference file gets changed to when loading LinuxCNC: use_toolmeasurement = False

Usually when I did a manual tool change, the spindle moved to a certain location and than a popup shows up to change the tool. After clicking ok, the actual tool measurement is performed.
Now the machine doesn't move, it just shows the popup.

(Homing, moving, starting the spindle all works. )

Waiting on another power supply for 12v as one of my cards needs that rather than 24v the machine provides.

You can probably use a small buck-converter to source 12V from the 24V line, rather than use a whole PSU.

Unfortunately, I’m still not getting a stable speed above 1900 rpm. I suspect this is due to the sampling of the 100 PPR disk — when I decrease the base period, the speed stabilises, and by reducing it further I’ve managed to get stable(ish) readings up to around 1900 rpm. Above that, HAL Scope just sees phase A as high rather than a pulse train.

1900 rpm and a 100 hole disc is 3.2kHz. What base thread rate are you running? a typical base thread of 25,000nS can count at 40kHz. 
(well, 10kHz allowing for oversamplng. I don't know if the Pi can do 25,000ns though) It's possible that something in the sensor path is electrically slow. 
 
Does Remora have faster encoder counters? 
 

I'm in the chat now with the same username as here.

Yeah the EC300 is the rt1052. Its become a slightly null point for the moment as I've managed to fix the issue temporarily. the pull up on the schmitt trigger for the opto interrupter sensor was too high off the shelf (cheapo Chinese modules) so the pulse width was way too wide, so above around 1800rpm it was just giving a logic high instead of pulses. now got a nice pulse train up until around 4500rpm so for now, i think this will work.

Pretty sure they have 7 years of warranty, and for me that is more than enough.

are you on the qtpyvcp chat? if not could you join so we could troubleshoot?

you might want to have a look at section 4.2.2 'Satisfying Build Dependencies':

disregard was able to break on dev here!

Hi Grotis, your work is absolutely impressive! I've been diving into LinuxCNC and your code to better understand motion control, and it's been a fantastic learning experience. I have a couple of questions I'd love your insights on:

Does your S-curve motion profile support an online trajectory generator like Ruckig for multi-axis systems?

Regarding LinuxCNC, I'm still unclear on how the trajectory planner functions. Could you provide a detailed explanation of how it processes a command like G1 to generate inputs for the kinematic module? Specifically, what roles do the trajectory planner and generator play in this process?

Sure, since it is Ethercat related I would suggest you start a new topic like "Notes on using OMRON R88D with EtherCAT" in the EtherCAT section:
forum.linuxcnc.org/ethercat

and attach the link to the github page in first post.

Error messages says pyvcp_panel.hal, line 8.
Only thing I can think of is the line PYVCP=pyvcp_panel.xml in the ini file
that leads to the line it doesn't like.I suggest you comment out that line. It is for customization if I understand right. You can always come back later and look at that.

I had no overrides active, everything was at 100%.
