Press F11 or F12 or on some PC's F8 after power on, see if you can select that SSD to boot from and also notice if there is more than one entry for it, usually the name of the SSD as one entry and another with UEFI SDD, try both.

Edit:
Is it an ACER?
those require setting a BIOS password to be able to disable secure boot.

that is awesome!!

Thank you for the reply.
I did what you suggested, before my post, and the motherboard does not recognize the SSD. Strangely it displays a very fast message that I was able to see:

There is no vBIOS support detected in this card.
'BIOS CSM/UEFI Mode' settings in BIOS will be changed to 'UEFI'

and automatically it moves to the BIOS screen, and the previous changed settings are converted to UEFI again.
Note that I do not have a separated graphics card.

Disable "secure boot" in BIOS.
Also enable "legacy" or CSM or both.

Changing from MBT (should be MBR or Master Boot Record) to GPT will destroy any info on the drive, so to do that would require cloning the partition (not the drive) to another drive, switching partitioning and then cloning back that partition. Either way you look at it, very dangerous and not much chances of working properly.
And more importantly, that is not the reason for failing to boot.

hello,
Thank you for your answer.
Sorry for the late reply. I've been a bit ill and didn't get a chance to test it.

I have changed the line as described.
It actually seems to be working better now.
I still have the problem that when I restart the coupler it doesn't work right away... it only works after I have loaded the configuration once with TwinCAT. I think I'll have to see which CoE register might have a different value.

@Konrad,

Thank you!

Besides that can I ask if the points raised by hmnijp ... are addressed?
A few are adressed now.

The algo is still using local smoothing. as shown on page 3.
But now it uses a 3d-clothoid instead of a spline, and uses the correct path deviation to fit the clothoid.

I guess to really have jerk limiting you not only need to be smooth in the time domain but also in the path, thus the use of clothoid(?)
1. The 3d clothoid fit's the trajectory with G3 continuity, as explained in the abstract.
2. Then we have scurve motion profile, wich is used for jerk limiting.
3. Then the trajectory can use different algo's for path optimalisation, like flattening out a zigzag motion. This will also contribute to jerk.

The ringbuffer is working. And to my surprise i did'nt need a seperate thread so far to fit clothoids.

 

Good morning.
I had a working system using a old linuxcnc version (+- 5 years old). It was running fine, but the motherboard needs to be replaced.
I was unable to boot the same SSD on the new motherboard, so I suppose that from what I have read that the issue is more likely because the current installation was done on the old MBR.
The new candidate motherboard only has UEFI so for what I have read, I must convert the current disk to use GPT.

I have read some online information, and there are many steps involved on the conversion. Should I try to start from a new installation or still the conversion would be less trouble. What is your opinion?

Thanks for your reply, andypugh.

Unfortunately, the counter and position values ​​of the EL5101 being used seem to be reset the moment index-enable is turned OFF. The position where it stopped at the end of homing is the correct position. The coordinates of LinuxCNC are 0, and the POS position of the EL5101 is the same as the HOME_OFFSET value. It seems that it is not possible to avoid the excessive PID deviation when index-enable is turned OFF. This phenomenon does not occur when homing is performed again.

Until now, I have tried converting the Count value instead of the EL5101 POS and using it for Feedback, but it did not work.

It worked fine with the EM7004, but I'm starting to think that an external torque mode amplifier cannot be used with the Ethercat driver.

Thank you.

Hi

thanks for your response. The input pin if the 5A BOB has to be inverted. It is giving an error that pin cannot be inverted. Please help.

 

The wiring will work for 3-4Axis mill and for Lathe.
For Lathe you need to set 'LinuxCNC->Machinetype' to lathe
and maybe remove 2 stepdir plugins.

If you need a Spindle-Encoder, you can add it freely to the other free ports.

It worked here. Running 40 times.

Pullups and pulldowns are possible on both but only after configuration

Xilinx chips have the added option of pullups before being configured
 

Hello, 
i would like to run delta vfd-b over rs485 modbus and integrate with qtdragon hd GUI, can somebody please point me in the right direction i am completely new to linuxcnc, 

thanks 

Glad you got a handle on it!

I have an external momentary button and i want to toggle between halui.flood.on and halui.flood.off
How can do this config ?

Also i have an output pin that activates lubrication pump and an output pin that activates a solenoid hydraulic valve that releases spindle tool clamp
where in hal must connect it in iocontrol v2 ?
