Hello,

I had a similar issue where I had to skip the grub boot installer step.

I found a solution is to install like normal and skip that step, then launch the usb boot drive live. From there, I had to mount the efi drive partition (/dev/sda1 I think it was). Then I went and renamed the Debian directory in EFI to boot and the grubx64.efi file to bootx64.efi and then everything booted fine.

I was doing this on an old Mac so it could have been a little different.

Its not possible to install Debian without an internet connection (hardwired is best) The Linuxcnc installer depends on internet (It uses the Debian Live INstaller). Try offline at your own risk

What pins do you mean?

If you run:

mesaflash --device 7i96s --addr 10.10.10.10 --readhmid

it will print the 7I96S's function (stepgen, pwmgen, encoder, etc)
terminal block pin numbers.

(replace the 10.10.10.10 with 192.168.1.121 if the 7I96S is jumpered that way)
 

Just checked 7i97t_7i74d.bin

md5sum=

4130ebee623115267327c166f8da9d39  7i97t_7i74d.bin


All encoders work, 7I97 sserial (0) and all 7I74 sserial channels (1..7) work as expected

 

I have only used firmwares from the Website. I also know that i only need a 7i97t with 7i74 firmeware. In the file there are a few firmwares with the 7i97t_7i74 Name. So the 7i97t_7i74d.bin is the right now?

Tomorow i will look further in to it.
And why the encoders arent counting.

might be a dumb question I have a 7i96s how how do you no where PIN numbers locations. I'm in the pnccofig it says pin # xx  but where is it on the board ?

This is the plan. Keep in mind, all who follow, that if you finish the installation completely offline-no internet access-your Debian package sources files will be empty. You will have to create the .sources file, or when you do sudo apt install you will get "could not find" and when you do sudo apt unpdate it will run through the updates and say there is nothing to update.

So pll-error remains 0 for me. App phase hovering between 9800 and 10500

What i did notice, i had all 3 axis vibrate like crazy upon first Launch today. Rebooting lcnc fixed that.

Edit: did another power cycle. No Vibration but sudden clunking on all 3 axis again

I think I overlooked the control type (because its in the pin list rather than a parameter.)

Thanks

QtPlasmaC updates - Master (v2.10):

• fix framing and missed interlock

I'm not sure if I set the control mode to 1. I'll have to check that. I thought I had most of the settings the same as the stepgens that were in use, and those are commanded by velocity command from the PID.

Hello, 

I can see merge of your progress to master? Am I right ?

Regards e.

7i97t_7i74d.bin  would be the correct firmware for a 7I97T +7I74

Note that with this firmware sserial channel 0 is on the 7I97T
and channels 1..7 are on the 7I74 (7I74 physical channel 0 does not work)

 

It seems I will try gmoccapy. It looks more friendly for me. And possibility to add stand alone pyvcp will help me too.

Once more, thank you for real help.

You can certainly get firmware that replaces the step/dir outputs to PWM/DIR,
but then you still need multiple channels of PWM/DIR --> +-10V analog conversion
and then you are still missing the multiple encoder channels needed.
So, a 7I78 is really the wrong starting point here. Mesa should have 7I97Ts
in 1-2 weeks so that is the simplest solution I see. Production 7I77Us are still
about 6-8 week away.
