VertexEvo Rev.2

Açıklama

This is the 2nd revision of VertexEvo . In this post I will cover only what's new in this version. Please follow the link above and read all cons and pros of such a major modification of Vertex K8400 prior to deciding to move forward. After this, and a number of previous upgrades (see my other posts) the print volume reached new maximum: X=192mm, Y=218mm, Z=194mm per nozzle. The distance between e3D nozzles is 23mm. I finally got rid of the original connector PCB that was always a constrain in printhead design. I created custom connector PCB and placed X-stop sensor on it. PCB is attached to the back of printhead and is barely visible. I have few spare PCB boards and can sell them assembled for the price of parts (about 15$ USD) + shipping. If there will be demand for bigger quantities, I foresee the price going down. The main cable and X-stop cable connector layouts remained unchanged, so you can just plug them into new PCB. Attached image specifies the function of each connector located on new PCB. PCB is mounted to the back of main Thing with a single M3x6mm screw and is also "sandwiched" between top and duct Things. Right and left XY clamps house LM8LUU 8mm Linear Bearing Ball Bushing 8x15x45mm, which are aligned with the clamps from the side facing the motors (see attached images). Lower bushing in the main Thing is the original from K8400. Upper bushing is LM8LUU 8mm Linear Bearing Ball Bushing 8x15x24mm. Most of the screws used in XY clamps are M3x12mm. X_visor…
