Pendant

Es wurde ein xhc-hb04 verwendet. Um diesen in Betrieb zu nehmen muss der entsprechende Treiber hier heruntergeladen werden.

Trotz einer neueren Linux CNC Version wurde der darin beinhaltende Treiber kompiliert.

Konfiguration

Zur Inbetriebnahme wurde in der Konfigurations-Datei (GoCNC_Step_2600.ini in unserem Fall) folgende Stelle im Abschnitt HAL angepasst werden:

[HAL]
HALUI = halui
HALFILE = GoCNC_Step_2600.hal
HALFILE = custom.hal
HALFILE = xhc-hb04-world-mode.hal
POSTGUI_HALFILE = custom_postgui.hal

[XHC_HB04_CONFIG]
layout = 2
coords = x y z a
coefs  = 1 1 1 1
scales = 1 1 1 1
threadname = servo-thread
sequence = 1
jogmode = normal
require_pendant = yes
inch_or_mm = mm

Die Knöpfe des Pendant wurden mit der Konfigurations-Datei xhc-hb04-world-mode.hal festgelegt.
