Ah i think i understand what you mean.

The model stays in a different position as the seted dh paramters ? Because i rotate the hand axis ( all 3) and the main tower.

Dh parameters= real positon/ angles
Vismach model = not build by dh paramters.

Or what do you mean?

The dh parameters i set are the parameters i get from right hand ruled cs. Possible i do it wrong. Because .. if i home over my sharpie marks the arm is in this position:

Joint 1 0 ( about 140 +- to the mechanical limits)
Joint 2 0 (90 deg to tower.. means parallel to base)
Joint 3 0 ( 90 deg to joint 2... means parallel to tower)
Joint 4 0 ( mid position +- 320)
Joint 5 0 ( mid position +-125)up and down same direction as joint 2 and 3
Joint 6 0 (mid position +- 280) left right same as joint 4

The values of A and D i get from the drawing
The Alphas i get from right hand rule cs.. and the signs for the A and D values i get with the alpha stuff.

And the angles after homing i checked with a digital pritractor... and the scales i checked with 90 deg moves looking to the digital protractor.

Hi grandixximo,
We really appreciate your dedication to solve the jerk limiting trajectory planner issue.
Can you share the update on any git repo to get wider community feedback started?
Looking for to testing the new fixes.

Because I'm busy with work, I'll do testing when I have time.

Not me.

I was able to reproduce this in a virtualbox test-installation. After entering a wrong name/passw  i was locked out. This solution gave me access again. And after that procedure, even entering the password wrong once, did'nt lock me out. Just enter correct password and login.

Good thought but its a laptop an older Dell no video card other than built in Video
don't know if it matters but password login error screen says... "your password is incorrect try again" cancel / log in boxes ...... nothing else and the same thing over and over when entering the password. I was super careful in the setup of these areas during setup
Tks

Hi Cmorley

I've tested it some more, and I don't need to touch "def external_offset_state_changed(self, data):"; it works fine without any changes. I don't know why I had the problem before, but the stop button is still a problem.
To stop the spindle, I have to press stop a second time.

If you see GRUB but after only blank screen, this may be graphic card issue. In this case try apply nomodeset kernel parameter at grub screen (there are many tutorials on internet). 

Thanks 4 the info
but I have not been able to get to the terminal yet
cant get past name and password screen yet.
have done 4-5 fresh install of the OS. they all hang up at the same place name and password screen
Thanks

Yes i use free ai to generate the single moduls of the vismach model. Then i bring all together. Thats why the model is in 90 angles..

Do you find wrong stuff in the ini or hal???

Thanks

For autologin you can do this, just after completing installation:


For auto login to Debian open a terminal:

sudo nano /etc/lightdm/lightdm.conf

Uncomment the following and add your user name, be sure to scroll far enough down to get past the comments sections.:

autologin-user=yourusername
autologin-user-timeout=0
 

Good Day: Adam
"I don't Like it" I just want it to work as prescribed which it does not seem to do when I can not even get past the login screen when i entered the password and user name in the OS install. oh ya I am a old man as U say and still building computers and doing installs from scratch.
have a good day

Cool

You are welcomed, always.
