Trajectory Planner using Ruckig Lib

very nice, my only other bitch is that, encoder and position feedback are not interrupt driven but polled, this creates issues with positional accuracy at very high speeds and very high accuracy.

Linear move exceeds joints positive limit

Category: General LinuxCNC Questions

Thanks for the reply.

My Tool length + Z15 would be 36,24mm.
My Workpiece has a height of 6mm + mounting fixture of around 20mm
Resulting in a height of 62mm
My maximum move on Z axis is actually 205mm

Is this move relative to my current position? Say, I am at Z=0 (meaning homed at the highest point) it would try to move further up by 36mm?
If so, then a move to a "safe position" lets say 100mm would be required beforehand?

Could it be that there is an issue with my machine config? From what I learned here , it should be correct that the max_limit is 0 (?)

My machine .ini configuration for the Z Axis is as follows.
[AXIS_Z]
MAX_VELOCITY = 30
MAX_ACCELERATION = 100.0
MIN_LIMIT = -205
MAX_LIMIT = 0

[JOINT_2]
TYPE = LINEAR
HOME = 0.0
FERROR = 10.0
MIN_FERROR = 1.0
MAX_VELOCITY = 83
MAX_ACCELERATION = 200
# The values below should be 25% larger than MAX_VELOCITY and MAX_ACCELERATION
# If using BACKLASH compensation STEPGEN_MAXACCEL should be 100% larger.
STEPGEN_MAXVEL = 112
STEPGEN_MAXACCEL = 250
# these are in nanoseconds
DIRSETUP = 6000
DIRHOLD = 6000
STEPLEN = 6000
STEPSPACE = 6000
STEP_SCALE = -640
MIN_LIMIT = -205
MAX_LIMIT = 0
HOME_OFFSET = 2
HOME_SEARCH_VEL = -40.0
HOME_LATCH_VEL = 5.0
HOME_FINAL_VEL = 10.0
HOME_USE_INDEX = NO
HOME_SEQUENCE = 0
HOME_INPUT_INVERTED = YES

FAN2001 Its old and obsolete or close to obsolete
I could send you a few in an envelope but if they are
both damaged, more maybe damaged as well.

Mesa 7i96S as the first in line, all in one, then to move things along, Mesa 7i85 for encoders and Smart serials, then add 7i84 or 7i70 or 7i71 for IO as these can be remote to any place on the machine and require only a single LAN cable to communicate.
Mesa boards start at something like 70$ and up, they are very fast and very reliable and i have used a lot of those on industrial machines that are in use daily.
Anything else you look might seem cheaper, it is not, and they will be extremely limited in expansion compared to Mesa.
You can probably do this cheaper with Remora boards or ESP32, but to much fuss and messy wiring and to much time compiling/configuring stuff just to make them work.
BTW, i did test ESP32 and it works, and i can build any damn thing i need, but the time and effort is not worth at all compared to Mesa "wire it/power it/run the machine."

Sounds like something has gone wrong with the Ethernet section of the 7I96S card.
It should be repaired/replaced under warranty, Contact Mesa or your dealer for instructions
 

Ok, i fear that too. But i will hook it to this Jtag debugger thingy at work, just for curiosity :)

Will post if i got some insights ..-

That looks OK.
Did you use the Network Manager to set up the network?
If yes, you need to check the "use this connection for local ..... " not sure what exactly it says as i am on the phone.
That is for wired network only, IPV4 settings.
You also have a wireless network and if that connects before the Lan, it will send all trafic through wifi, if the above is not set for wired network.
 

I think i used networkmanger, but iam also able to set the ip with ifconfig  :)
The Ip Stack will notice 10.10.10.10 is on the same subnet  as 10.10.10.2/24, so it will allways send packets for 10.10.10.0/24 to that interface. (unless statics routes exist)  It also worked for like >1 year in this config and it still works for the lathe mesa with the same ip as the "broken" one. I also tried some other Laptop, with no luck

>>are you compiling with release or debug?

I'm just compiling with this sequence:

/tmp$> make

>> idk which one but people report trouble with one

Multiple controller boards

Category: General LinuxCNC Questions

Greetings,
I'm wondering,  it's it possible to connect a couple of controller boards  (like Arduino) to LinuxCNC, i.e.one for XYZ, anothe for ABC, one more for adding a turret or a double spindle..?

Why not, it seems to me there must be a way now as computers got super processing powers.

If yes, is there a specific controller board type(s) that can be connected together? Maybe several types may inter communicate with LinuxCNC and to themselves too?

Or maybe connect a number of these boards to a number of servo motors and drivers and other boards to other stepper motors and drivers?

Exactly, I am just at a beginner, trying to figure out how to make my super fancy machine., so do you think my dreams are valid, or can be true soon?
Is there some hardware that I have to buy prior to others, you know in order to plan the priorities and budget, but make sure I want to build the fancy CNC?

I'm sure there are many like me.

Thanks,,
Byes

Yes it is mine, it is the old one with my full name as channel name. Plenty of stuff there also, wanted to transfer videos to new channels but there is no easy way.
My other channels just in case:

Ok. I had a moment.

For me it looks like U10 and U6 had a issue. I iced the board and attached 2A to the 3,3V Rail. Both get warm.

I will desolder them when I have time. For the case. Where can I get spareparts?

Receiving GStat messages in GladeVCPs

Category: GladeVCP

This sounds like a question for Chris, and might do better on the dev mailing list.

Yes and I was pretty sure he will read this ;-)

Sorry for my late reply but I was expecting to get an email notification...

From hal_glib.py:
Thinking more about it...
If your gladevcp panel does not have gremlin object in it, you will not get gcode properties generated in that pythons context.

Why do you think so? It's just a textual message giving some information about the G-code.

From hal_glib.py:
Specifically ignores loading with the same filename (reloading)

Okay but why do I get a signal though when I run it as a user command file?


In detail, I have this VCP:
#!/usr/bin/env python3

from hal_glib import GStat
GSTAT = GStat()

class HandlerClass:

    def __init__(self, halcomp, builder, useropts):
        self.builder = builder
        GSTAT.connect("graphics-gcode-properties", self.gcode_properties)
        GSTAT.connect("file-loaded", self.file_loaded)
        GSTAT.connect("line-changed", self.line_changed)

    def gcode_properties(self, obj, data):
        print("[VCP] G-code properties:", data["name"], data["size"].replace("\n",", "))
        
    def file_loaded(self, obj, data):
        print("[VCP] File loaded:", data)
        
    def line_changed(self, obj, data):
        print("[VCP] Line changed:", data)

def get_handlers(halcomp,builder,useropts):
    return [HandlerClass(halcomp,builder,useropts)]

and I have a user command file in gmoccapy running with
USER_COMMAND_FILE = custom_init.py

def gcode_properties(obj, data, widgets):
    print("[rc] G-code properties:", data["name"], data["size"].replace("\n",", "))

def file_loaded(obj, data):
    print("[rc] File loaded:", data)
    
def line_changed(obj, data, widgets):
    print("[rc] Line changed:", data)

hal_glib.GStat().connect("graphics-gcode-properties", gcode_properties, self.widgets)
hal_glib.GStat().connect("line-changed", line_changed, self.widgets)
hal_glib.GStat().connect("file-loaded", file_loaded)


When first open a file, I get this output:
[VCP] File loaded: /home/cnc/linuxcnc/nc_files/3D_Chips.ngc
[rc] G-code properties: 3D_Chips.ngc 200509 bytes, 4714 gcode lines
[rc] File loaded: /home/cnc/linuxcnc/nc_files/3D_Chips.ngc

On reload I get only the messages from the user command file:
[rc] G-code properties: 3D_Chips.ngc 200509 bytes, 4714 gcode lines
[rc] File loaded: /home/cnc/linuxcnc/nc_files/3D_Chips.ngc

When staring the program, I get the line-changes from both:
[VCP] Line changed: 24
[rc] Line changed: 24
[VCP] Line changed: 25
[rc] Line changed: 25
[rc] Line changed: 26
[VCP] Line changed: 26
