I know this has been discussed ad nauseam on this forum but no matter how many posts I read or years I've used LinuxCNC, I just cannot understand how to accomplish these simple tasks.

I want motion.probe-input to be triggered when hm2_5i25.0.7i84.0.0.input-08-not is True AND motion.digital-out-00 is True.
I also want and MDI command called when hm2_5i25.0.7i84.0.0.input-08-not is True AND pyvcp button is clicked.

When I try to use the hm2_5i25.0.7i84.0.0.input-08-not pin twice, I get an "already in use" error. How can this be accomplished?

Thanks.

of the repositories that looked "hopeful"
Remora-main, and Remora-RT2052-cpp-Main had remora-the-3.0.c
both the same -- neither worked (forgot to incclude that)
and the one listed which also didn't work -- (same error)

I think maybe the 3.0 one I worried was specifically related to the EC500 (all the remora-??? directories under LinuxCNC appear from filenames to be ec500 based

If your board has the RT1052, refer to the page I linked to, and only install the components/firmware/configurations referred to in the documents. The linuxcnc .hal file configuration doesnt matter if its EC500 or NVEM. The config.txt is important to match with the board.

Note that

setp hm2_5i25.0.encoder.00.filter 0

only changes the X axis.

Plotting the velocity, commanded and feedback position
should give the information needed to diagnose the issue.

be sure to set the max z travel to just a few mm larger than the spindle_zero distance. this is the distance that is commanded for the z minus probe direction and will stop the probe event if no trigger event occurs at the end of travel.
 

Hello! Today I was working on a GUI and found what the problem was! Last time I didn't do it according to the instructions. I wrote Index with a capital letter, but it should have been with a small letter. It turns out that index is case sensitive. I did this today and it worked. This is much faster than typing commands manually. Thank you!

Question 1:
yes s0 and se are the end points. The first clothoid of the spline P(s) starts at s0 and the last (4th) clothoid of the spline ends at se.
P_traj.(s0) = P(0) and P(s4) = P_traj.(se)
P(s) is the clothoid spline and P_traj.(s) are the curves at the beginning and end of the spline.

Question 2:
That's correct. You can either calculate first all the derivatives and transform them afterwards or you can first transform v_a1 and v_a2 and then calculate the derivatives.

Question 3:
Exactly, this is one of the boundary conditions. it is the z component of the first derivative in the starting point s_0 in the transformed coordinate system.

Question 4:
Fresnel Integrals show only up in equation 44. Until now we did not need them.

I think you are getting things confused and did steps not in the instructions. If you load firmware.bin onto the SD card the first time, it will change to firmware.cur if it loaded correctly. Your config.txt file is stored on the sdcard, it needs to remain inside the board.

if you loaded the firmware using other methods, it is possible you overwrote the bootloader in which case the firmware will not load. you might need to reinstall flash the board with bootloader, then reload the firmware.

with the stock bootloader on the octopus, all you need to do is
- put the firmware.bin on the sd card
- put config.txt on the sd card
- put sd card in octopus and leave it there
- thats it
