Configuration problems 7i95t Mesa card with servo drives

Hi,

I am new to linuxcnc and Mesa cards and i am stuck with the configuration of the Mesa 7i95t. I am building a CNC router for mainly wood. I have T6-400W servo motors and a Lenovo ThinkCentre m93p PC to run Linuxcnc 2.9.1 Debian.
So, after installing linuxcnc i powered the 7i95t card with 5V and wired the step/dir to one servo driver, set the ip jumpers to 10.10.10.10 and after some network setting tuning i managed to ping the board and mesaflash.
I started using mesa Configuration Tool from John, which detects the board, i loaded the firmware and started to configure one axis to see if i can get some movement.
But here is where i get stuck, i build a config and run the gui, where i try to jog or home the one axis but i just get following error. The step/dir ports on the board measure around 5V constant which i find strange.
I've been trying to find the problem(s) for a couple of days and because i am reading that building a config could be somewhat straight forward I think i am missing some big steps here.
HAL an ini files are attached but they don't seem to be what they should be...

I hope this kind community can point me in the right direction, i have really been trying to investigate the problem but no result.. Excuse my beginner mistakes.

Thanks in advance for the help and if you need more info on my part please let me know.

Kind regards,

Mattias

A lot of stuff missing there in the hal file, no stepgen pins
Try making a normal 3 axis config and test.

Thanks for your reply!

I made a new xyz metric configuration, starting with quick start option and going through the menu's filling in the blanks (for as far as my knowledge goes).. Still get an almost empty io.HAL file..
Can you tell me where the stepgen pins are configured exactly? Thanks again

When i press build config, i get the following on the info screen:

Configuration checked OK
Update INI Function
Updated /home/matticnc/linuxcnc/configs/7i95t_xyz/7i95t_xyz.ini
Building /home/matticnc/linuxcnc/configs/7i95t_xyz/main.hal
Building /home/matticnc/linuxcnc/configs/7i95t_xyz/io.hal

It seems it does not complete the building of the files maybe....?

Thanks for the help.

Do you have the latest version of MesaCT?
github.com/jethornton/mesact/releases
BTW, do not flash any firmware.

I have version 2.1.1. should also work right? I am trying to update to 2.1.2. without success, the manual says to delete .deb file and replace with the new .deb. but, gdebi install will just exit when i press install....

So now i am trying with terminal commands..

If you have any other suggestions, please let me know. Thanks!

Hi tommylight,

I have updated mesaCT to the latest version: 2.1.2. Still have the same issues unfortunately. Also turned off secure boot in BIOS because is got an error about that when starting linuxCNC.

I think the issue still begins with the hal files being not well generated. Like you say; no stepgen or any axis/joint lines.

I am really stuck and have been trying for days, so if you have any more recommendations on how to narrow down the issue please let me know.

Thanks in advance

Can you start MesaCT from a terminal, see if it outputs any errors when you generate the config.

When i run from terminal i do not see a lot happening (see screenshots).
Also tried with sudo; it creates configs in /root.. It does also make a tool.hal file which it does not do when running without sudo..
Thanks for you quick answer

Perhaps this could be moved to the MesaCT thread as this is MesaCT related

(I also tried this and unless there's some trick, the hal file is missing all the
stepgen setup and connections)
