Autres Post-pro découpe plasma

Bonjour ,

La fabrication de ma plasma est quasi fini je suis sur les test de post pro et après il ne me manquera plus qu a tester la commande de mise en marche du plasma mais j avance par étape.

J utilise com logiciel pour le g code sheetcam j ai récupérer le post pro d un collègue et j essaye de l adapter à la mienne le soucis c est que autant fabriquer ma machine ca reste pas trop compliqué , le post pro c est pas mon truc j ai l impression que c est matrix lol .

Je vais vous mettre le post pro , quand je lance le programme il va palper l axe z et remonte à 1.5 mm (ce que je vois dans le programme ) il simule bien la découpe et après remonte en z

Le soucis déja c est que ca marche qu une fois si jamais je relance le programme il ne va plus palper et refais le programme beaucoup beaucoup trop haut .
Après autre question ou dans le post pro d ou sort la hauteur de coupe et la hauteur de dégagement en Z ?

Merci

-- created 1/1/06
-- Based on plasma1.post


-- Modified 21/6/2010
-- added option for 'nil' plate marker z
-- Added support for plate marker tool type as well as tool number based plate marker

-- Modified 4/11/2010
-- Added: Reference the torch on the first pen down if the plate marker is the first tool used.
