You have the host address set to 192.168.1.121

This cannot work, it must be set to a address in the same range but not
the same address as the 7I96 say 192.168.1.100/24
(do not use 192.168.1.100/8 as that overlaps with your WIFI range)

no idea if it is up to date:

Thanks! I forgot it was already on Github! This is the latest that was sent to create the PCB. As I wrote, If I make a new version I would make some changes.

I will try tomorrow on another machine

I could not use Eagle so I have remodeled Oliver's OCB in KiCad.
I use different connectors. Noved the 5 outputs to the oppesire sides and have 5V/24V selection on all inputs (also wih option to change resisor values). Also added some capacitors.
If I make a new version I would use 6 pin JST to get 5V from the Raspberry PI. Possibly add MAX485+protection circuit to the board.
If there is demand I can put the Kicad files on github.

Maybe I should change the dip switches

Fixed the tittle.

Set the PC address to anything but 121 at the end, from 1 to 254, but not 121.

I can confirm this is the proper place to edit the Steps Per Degree.

Some math to help out future people setting up their own 4th axis.

Micro Steps = Driver Pulses / Steps Per Revolution of motor

(micro steps * motor steps per rev * total gear reduction) / 360 = steps per degree

For example... i used a 200 step motor with 1000pulses on the driver and a 50:1 harmonic.

1000 / 200 = 5 Micro Steps
(5 * 200 * 50 ) / 360 = 138.888888 steps per degree

So i would enter 138.888888 as the SCALE of the 4th axis

The microarc Tormach has setup for 141.666666 around 51:1... not sure how they hit that total gear reduction.

A little update:) ... it works as a horizontal miling machines  :d

 

I am getting this message.

when I ping 192.168.1.121, it responds fine

 

HI bertoldo
It doesnt work.

also when i try to update i get the following

Thanks to all. It was my Mistake, There was a G53 Z0 M6 at the top of Gcode File.

after i removed that all was OK.

There is home=0  home_search_vel=2  home_latch_vel=-0.625 .Somehow  i think, if home is 0, home_search_vel should be minus direction and home_latch_vel  plus direction, and scale inverted instead.

With this setup, after homing , do  mdi G0 G53 X1 Y1, does it go in the right direction?

If you have an HF start plasma, the HF is created between tip and electrode, you might still not believe me but anyways.
There could be some HF in the tip so keep that in mind.

Yes, that is the reason i never advise using such torches with ohmic.
And all the plasma sources i have are HF/HV start ones.
I am sure i can cobble something together to avoid the high voltage but not worth it, i like my THCAD's not crispy
Oh, i do have a Hypertherm MAX 43 that has blow back start but i have no consumables for it, despite ordering them several times.
