I  modded my solidoodle 3 a lot as well, pcb bed, e3d v6, lawsy carriage and replacement rods and bearings, 8mm threaded z-axis rod with anti backlash nut, hobgoblin extruder hob, 1/32 step stepper controller and 1/32 stepper motor for extruder, full enclosure and top spool mount, and new power supply. Next I'm going to mount the power supply onto the back of the printer and put a switch on it and then finally clean up all my wiring and make it neat. All of those upgrades I would recommend, it's basically an entirely new machine at that point haha.

I have been playing with 3 new printer since last 2 years, and my solidoodle was left aside...

now I'm trying to refurbish it completly.

so far I have changed over the years:

-lawsy carriage.
-E3d V6 hotend
-new heat bed (larger stronger)
-glass bed
-bed stabiliser (sort of)
-titan extruder-new board casing plus fan.
-new power supply.

-Self lubrifiant bearing

and added another fan on the extruder stepper.

Now I'm gonna take it completly apart and clean the case (probably paint it in black too)

I'm looking for idea on what I can do, or add to improve it.

What I wan tto do  is

Be able to swap hotend easly. spesificly from 1.75 to 3 mm (probably need to be bowden)
I recently bought a microdelta rework and they have a tiny board to plug the fan, the termistor the hotend ect... and a centrale cable, the design is fantastique.

I would like a less complex but similar idea.

(anyone able to help me do it?)

I like to do a core xy conversion (does the one for the sd4 is compatible for the SD3)

also I know that the bed stability is a issus, but I don't realy know how to adress it.
I 'was thinking about going the bigbox way... or somthing like it.

that lead me to the next one, my new udelta rework as a custom bord that is fantastic and realy cheap
