Shauki as speak privately put inside atx ramps not possible,

Shauki as speak privately put inside atx ramps not possible, i take 2 old ,less of -5 year of life, atx power supply with different size and I confirm is no possible
but i think 2 fast solution for take “inisde” display and ramps.

normaly need remove all no need cables better if disold from board.

solution n1
take 4 bronze hex spacer to take insert in middle for take open case for have right space to place ramps inside (upside and fixed on top) and stepper placed on fan. on top with another 4 hex spacer add display

solution n2 ( need other fan)
take cover from other death power suply and make 45° on back insert display on beck or on front (depends if want make a large hole) and on back fix ramps with second fan

after can decide if fix some connector on case or close all with long cables for connect to frame.(i think use 4 pcs rj45)

my idea of configuration of 4 rj45 ports:
1° x y motors
2 ° z e motors
3° 12v HE (dobule pair)- HE HB sensor
4° xy endstops .
2 more cable for HB…300w is too much for rj45…:slight_smile:

think about my 2 solution… showed in last photos (manualy)

Might not be an optimal solution whithout shielding , due to Emf influences on arduino boards. Maybe a Faraday cage would help, but needs some calculation + GND

No think 50hz make some issue on 16mhz of mega…but can test output with oscilloscope for see if make some spike during use pwm signal (i want try solution n1. )
