Linuxcnc Gmocappy -> Fragen zum Nullpunkt

29 Mar 2018 14:01 #108067 by Michael1992
Hallo Forum,

bin neu hier. Habe mir vor einigen Monaten eine CNC Fräse gebaut.
Nun habe ich in Fusion360 ein Bauteil erstellt, welches ich mittels
Linuxcnc Postprozessor in ein G-Code exportiert habe. Das Uploaden
auf Linuxcnc hat ebenfalls funktioniert. Nachdem ich jedoch dem System
den Werkstücknullpunkt "gezeigt" habe, fährt meine Z-Achse jedoch immer
auf den Maschinennullpunkt. Im G-Code steht Z-0 für die Oberkante des Werkstücks.
Für die Referenzfahrt der Z-Achse, fährt die Achse nach unten.

Kann mir irgendjemand bitte helfen?
Danke :)

Hier noch mein G-Code, der mir Fusion360 ausgibt.

Hello,

Thank you for your answer. Please excuse my bad English.

I loaded the program in Linuxcnc and touched the workpiece. Unfortunately, the Z-axis always moves to machine 0. I get an error message that the stop is triggered if you continue driving. Is the error in G-code?

If I clip the tool change, for example T60 M6 in the G-code, it works. Is this an automatic tool change? In addition, I have to rewrite Z0 to Z150, so that the CNC milling machine does not move to the stop. My Z-axis reference switch is on top. This means that the Z-axis has to go all the way down. That explains why Z0 does not work. But how can I change this to fusion360? I would also like to do a manual tool change. Can you help me?

Hello,

I probably found the mistake for the tool change M6. Apparently HAL component called hal_manualtoolchange does not exist for me.
For the Z axis, I have now rebuilt the reference switch so that the Z axis goes up to the proximity switch.
How do I have to adjust the .ini?

Danke nicht mir, besser danke Talla.
Er hat eine ganze Menge recht brauchbare Videos zu lcnc gemacht.

Er ist wohl mehr in der CNC Ecke aktiv.
