G-Code, CAD, and CAM discussions / Fusion 360 CAM, Mach4 Mill post-processor, probing, spindle speed out of range

« on: January 08, 2018, 12:05:13 PM »

Hello everyone,

I've been browsing the forum for any hints concerning my issue, but, no luck; so I'm starting a new thread...
Sorry, if this is already beeing discussed somewhere else in this forum.

I'm trying to get some "probe" commands exported from Fusion 360 CAM to the Mach4 Mill post-processor (rev. 41728 and earlier).
The G-Code generated so far doesn't look bad, I guess?

(PROBETEST)
(T100  D=2.96 CR=1.48 - ZMIN=-4. - PROBE)
G90 G94 G91.1 G40 G49 G17
G21
G28 G91 Z0.
G90

(PROBE1)
M5
M9
T100 M6
(3D TOUCH PROBE)

M9
G28 G91 Z0.
G28 X0. Y0.
M30
!Error: Failed to post data. See log for details.

But then the post-processor stops,
and the aforementioned "details" are poppin' up in the following error message:

Error: Spindle speed out of range.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Error: Failed to invoke function 'onSection'.
Error: Failed to invoke 'onSection' in the post configuration.
Error: Failed to execute configuration.

Seems like the Mach4 post-processor doesn't like to have 0 rpm set for the spindle speed (default while probing),
whereas standing perfectly still is mandatory for my touch probe (regarding the cable attached to it and all).

Ain't probing implemented yet in this post-processor, or are there any other ideas?

Sorry for my gibberish... I'm only a German CNC hobbyist trying to get some meaningful responses;
I prefer the English forum just because you guys are much more willingly to help - and way more friendly than the Germans... 

Thanks in advance,
Marcus
