This attached part of the machine diagram is fuzzy So I am not sure what it depicts analog or digital control. May be Martin could rescan this part  translate any words to English and re-submit to  just make sure you have an analog control drives. On the diagram Analog out is a feedback signal not contrl signal, control signals are inputs. 

On the left of the analog-out signal are four inputs control wires, they would reveal the type of controls of the drives.

 

Just choose "use entire disk".

Thank you very much Master PCW I performed the following procedure to find the signal:loadrt hm2_eth board_ip="10.10.10.10" config="num_encoders=8 num_pwmgens=1 num_stepgens=5 sserial_port_0=3000"setp hm2_7i96s.0.encoder.00.counter-mode 1setp hm2_7i96s.0.encoder.00.filter 0setp hm2_7i96s.0.encoder.00.scale -1setp hm2_7i96s.0.encoder.01.counter-mode 1setp hm2_7i96s.0.encoder.01.filter 0setp hm2_7i96s.0.encoder.01.scale -1setp hm2_7i96s.0.encoder.02.counter-mode 1setp hm2_7i96s.0.encoder.02.filter 0setp hm2_7i96s.0.encoder.02.scale -1setp hm2_7i96s.0.encoder.03.counter-mode 1setp hm2_7i96s.0.encoder.03.filter 0setp hm2_7i96s.0.encoder.03.scale -1setp hm2_7i96s.0.encoder.04.counter-mode 1setp hm2_7i96s.0.encoder.04.filter 0setp hm2_7i96s.0.encoder.04.scale -1setp hm2_7i96s.0.encoder.05.counter-mode 1setp hm2_7i96s.0.encoder.05.filter 0setp hm2_7i96s.0.encoder.05.scale -1setp hm2_7i96s.0.encoder.06.counter-mode 1setp hm2_7i96s.0.encoder.06.filter 0setp hm2_7i96s.0.encoder.06.scale -1setp hm2_7i96s.0.encoder.07.counter-mode 1setp hm2_7i96s.0.encoder.07.filter 0setp hm2_7i96s.0.encoder.07.scale -1

the result was satisfactory: 

 

the result came out on encoder 6 and 7 of the 7i96s, thank you very much, I will follow the next recommended steps for this to be recognized as Z movement.

It sounds like this message is indeed referring to the USB flash drive, thank you.

I have a new SSD ordered that should arrive tomorrow. After I get it installed, I’ll attempt the install again.

Any feedback on how this new SSD should be partitioned for best performance? Or will the install partition it appropriately?

Did you set the number of encoders to 8 in the hal file?
Enc0 and Enc1 are MPG encoders as you have the Mesa 7i77 set to mode 2 or 3, that makes the total number of encoders 9, 1 on 7i96S, 6 on 7i77 and 2 of MPG on 7i77.

Hey scotth,

many thanks for your tip.
I will have to check if I know how.
Sadly I`m not in the linux/unix-Space, so I´t a little hard for me finding the right code or menu.

Good morning, ,Mr. Tommy, light thank you for your reply, but the available encodes for 7i96s are:

 

and for 7i77 they are these:

 

What could be the reason why this 7i96s board cannot read the frequency but the 7i96s in the laboratory can read it?

@Wez,
How the hell did you cram all that stuff into an ESP32?
Hal2UDP version works, your version is refusing to work on a Wroom module, no network, and ipconfig will reset it.
The rest seems ok, can set motors, enable wifi, etc.
Will report back later if i manage to find the culprit.
It is the "doit" version with strange pinout so had always issues with it, will also try another board

Yes, it can do indepent axis foam cutter, i have made several of them, and it can have configurations for 2 axis with 4 joints or tandem and a configuration for independent 4 axis, even 5 is you want to add a rotary table.

Thank you for reply, by meaning scara - i do have in mind to replace two linear rails with two steppers and some gears on it. For each side. For smaller one it is ok to have 1:4 gear ratio to have ok resolution for foam cutter. With 8 microstep it shell give 0.1227mm step ~0.5mm at 500mm arm radius.

I have made mre than one foam cutter and i do hate to drag it around. Scara would be wery compact then not used.
 

Not sure if anything changed, but XYZ were always linear and ABC were always angular, but i know i have set A axis as linear and it worked for what i need. The gremlin (vizualization on GUI) might still show it as angular, though, and i do not know how to change that.
Should wait for someone with more knowledge to chime in.

In the hal file, the loadrt line containing Mesa IP address, the number of encoders is set to 1, should be set to 8 i think, see your other topic already replied by PCW.
Then you would have to also change the encoder number, most probably from encoder.00 to encoder.06 for every entry of that encoder.

...just discovered this a few days ago and i am really impressed! Really nice work, also with the configuration wizard in the docker container! 

Just stepped inside the LinuxCNC world with a rudimentary BOB setup, so maybe a bit early... but i am really considering having a look at this

Cheers!

Hello. Is it possible to configure linuxcnc for two scara x/y and u/z axis from same controller ? Ie - i would like to make a cnc foam cutter, and have independednt sides controlled from same controller for tapered cuts. .
