LinuxCNC on Raspberry Pi 5

Is there a GitHub tracking thread (or something else) for those patches?

I would be really interested in following that thread.

"Help" is a strong word for what's happening here.

You seem to be getting frustrated.  Maybe I can help.

Correct me if I'm wrong, but your situation is that you have a Mesa 7i96s and Clearpath SDSK motors.  You want to:
  • Set some rational values for max velocity and accel
  • Connect the HLFB pins to the 7i96s
  • Make LCNC do something with the HLFB signals

Have I got it right?

Mach3 machine, some questions.

You say LinuxCNC is way way better than Mach 3.

How so?

In short:
Mach3 = extremely limited
LinuxCNC = extremely versatile, like the T1000 from The Terminator, it changes shape to fit almost everything as far as machines go.

Perhaps I'm still misunderstanding, but the actuator you showed looks like it has a leadscrew with a pitch more like 5mm, not 50mm.

Just to make sure we're talking about the same thing, 'pitch' to me means the spacing between the screw threads. 50mm is an abnormally steep pitch unless it's a multi-start screw.

In other words, does the carriage really move 50mm for a single turn of the screw?

Yes, if the channel in enabled in the hal file, it should be recognized.

You can see the 7I74 pinout a bit better with:

mesaflash --device 7i97 --addr [card_ip_addr] --dbname3 7i74

Thanks for he fast reply,
I did try an 7i73 on wat i now guess is channel 0 of the 7i74.
this was not recognized so i tryed with the other ports in the HAL.
Wat i now think if i understand write is that if put on any other channel it shuld probably just be recognized.
I will try this tomorrow.
Againe thanks for the fast help.

7I97 + 7i74 SSereal problem

Category: Driver Boards

The 7I97_7I74D firmware only has one sserial port (port_0).
This port has 8 channels, channel 0 on the 7I97
and channels 1..7 on the 7I74. (channel 0 is skipped
on the 7I74 to make the channel numbering match
the 7I74 documentation)

The reason for this is that 2 sserial ports will not fit
in a 7I97's FPGA (with the standard 7I97 I/O).

The 7I97T's 7I74 config does have 2 sserial ports and
9 total channels. (possible because of its larger FPGA).

Lcvette, Sorry, when I wrote this originally the site was having issues and I could not post. seems I forgot to add them when I tried to post the second time. 

Let me know if you need anything else! 

All the help is appreciated! 



for clarification, if the file names of the files you uploaded are the ones you intend to use, you need to use them in the ini file call as shown below:
[HAL]
HALUI = halui
HALFILE = probe_basic_setup_2025-01-09.hal
POSTGUI_HALFILE = probe_basic_postgui.hal
TWOPASS = on
