3D printer Test Bench

Updated 28-09-2019 With this test bench design I'm aiming to develop an as complete as possible 3D printer test setup in order to do all functional test related to controller board settings and code used. Please let me know if I miss some relevant functionality that could help completing this design. I uploaded a 3D pfd file in order for you to manipulate the design as you like. Double klick in the picture and you're ready to manipulate the design. With the part tree you are enabled to switch off and on the parts in the design. With the part tree you also have a list of all used parts. Good luck Content at this moment: 28-09-2019 INPUTS: Thermistor 2x+1x, PT100 sensor module 2x, End Of Material sensor 2x, STOP material sensor 2x, End stops NC (2 wires) 3x, END stops NC (3 wires) 3x, Raspberry Pi 1x, PS_On switch 1x. (I removed BL_Touch and proximity switch because all our printers don't need bed leveling. (Precise build takes care of that) OUTPUTS: Extruder 0 and 1 Hot End 0 and 1 Dual Hot End 0 Hot End Fan 0 and 1 Dual Hot End fan 0 Part Cooling fan 0 and 1 Extra Fan Stepper motor X, Y, Z and Z extra 220/115 Power inlet with fuse PS_ON power monitor module Heated bed Mosfet Controller cooling fan 24V power supply SKR Pro V1.1 Controller board mount (Lookalike for LERDGE K board and MKS Sbase 1.3 board 3,5" TFT screen Raspberry Pi 4 Plywood Base plate and some 3D printed mounts
