Is there any reason to set the values for pins / parameters in the INI vs. the HAL?  Is using the INI simply a best practice? 

For example, this line are in the HAL file:

          setp pid.u.Pgain                            [JOINT_4]P

and this in in the INI file

          P                    = 1000.0

I assume I could set this value in the HAL file without using the INI file:

          setp pid.u.Pgain                            1000.0

 

ACTIONS TAKEN:
I re-added these lines to the HAL file:

setp pid.u.Pgain                            [JOINT_4]P
setp pid.u.Igain                            [JOINT_4]I
setp pid.u.Dgain                            [JOINT_4]D
setp pid.u.bias                             [JOINT_4]BIAS
setp pid.u.FF0                              [JOINT_4]FF0
setp pid.u.FF1                              [JOINT_4]FF1
setp pid.u.FF2                              [JOINT_4]FF2
setp pid.u.deadband                         [JOINT_4]DEADBAND
setp pid.u.maxoutput                        [JOINT_4]MAX_OUTPUT

and these to the INI file

BIAS                 = 0.0
DEADBAND             = 0.00005
MAX_OUTPUT           = 10.0
OUTPUT_SCALE         = 1.000
OUTPUT_OFFSET         = 0.000
P                    = 1000.0
I                    = 0.0
D                    = 0.0
FF0                  = 1.0
FF1                  = 1.0
FF2                  = 0.0

RESULTS:
That seems to have fixed the speed problem I was having. However, a new problem has now arisen:  When I initiate the move, either by jogging (e.g., 0.1") or using the Gcode (e.g., G0 u-0.1 f1), the stepper motor

1. moves the piece some distance (let's assume it is 0.1"),
2. reverses back that same distance,
3. then re-executes steps 1-2 until I stop LinuxCNC.

Hallo und danke,
vor etwa 1h habe ich eine andere Möglichkeit gefunden. In der pncconfig auf der zweiten oder dritten Seite gibt es eine Option, die man an oder abwählen kann. Heisst sinngemäß "Homing vor MDI" notwendig.

First of all, thank you so much for your effort and for sharing your files—without them I never would have gotten mine working.
I learned the hard way that it’s not practical to have one machine serve as both a router and a plasma cutter, so I developed a very affordable “plasma router” that works perfectly, and now I keep the two machines separate.
I’m leaving a video so you can see it running in case it helps, and a link where you can download the 3D model and wiring diagrams. I’m sharing it as open-hardware to give back a little of the much that the community—and generous acts like yours—have given me.

 Hi..have an ac servo motor setup as 4th axis on wood lathe for position to carve....now i was hoping to use same motor for continuous run as lathe turning...Is this doable?...if so does it require any additional wiring/...I have a Mesa 7i96s  with ethernet..I normally would just try and figure out but I am very pressed for time on this one so any help would be greatly appreciated..

Thanks!,

Rick

Moin,

in deinermaschine.ini
Also die ini heist so wie du deine Maschine konfiguriert hast.

I don't use the pendant anymore and rely on a touch screen and wireless keyboard because my machine is a dual-use plasma /router, and I couldn't get plasmac.comp to play nice with the pendant. But once I get the table put back together, I will revisit and see if the berry is worth the squeeze.

I found it at pncconf and unchecked "Require homing before MDI/Running". Now it works.
Thanks a lot!

Try setting the HOME_SEARCH_VEL and HOME_LATCH_VEL to 0

I did it at all Joints like this

[JOINT_0]
NO_FORCE_HOMING = 1

and restarted Linuxcnc but i still get the error not "homed"

You can temporarily disable homing by setting

NO_FORCE_HOMING = 1
 in all joint sections of the.ini file
 

At the moment i´m not able to do a homing in Linuxcnc. If i try a MDI command it says home all axes...

That looks OK

Does the spindle speed control work at all. that is,
does MDI command M3 S12000 give you about 12000 RPM
and ~5V output?

Hope these are the right files. Iḿ a newbie
