Description

Lit motorisé pour laser K40

Un grand merci à Jean Philippe Civade pour son excellent article.

Son software est très bien documenté, je n'ai eu aucun mal à l'adapter à la réalisation d'un circuit imprimé (K40_Bed_Software.zip et K40_Electrical_Board.zip)

Merci à José pour son excellente description :) https://www.youtube.com/watch?v=iLiYV7eDE7Q&t=1159s

J'ai utilisé une CNC3018 Pro pour la réalisation du circuit imprimé époxy FR4 et des protections thermiques. Les fichiers d'outillage sont stockés dans le Zip (K40_Bed_Thermal_protect.zip)
