I have no SSD only 2.5" HDD and it will have to do for now.
Trying to setup RPi headless output via VNC on my tablet with 1280x800 but I can not find the correct settings in RPi to get full Gmoccapy on the tablet.
Any hints on how to get this working is much appreciated.

I have managed to get display resolution fixed so now almost the whole screen of Gmoccapy is there.

A good night sleep and one old fart can tinker better
Config.txt = 27
and
change Display setting in RPi menu to 1200x800 and all is well.
I was close yesterday with a bit of overscan that bothered me.
So now I will copy my test settings from my PC and hopefully I can get all axis to move, that is the first goal then add IO.

Hi tecno
You can get a pi4 ssd for low budged around 20-25$ fx wd-green ones.
I would propose you to go that road as soon you have prooven pi4 bbeing your solution.

Looks like you are not running a real time kernel...
