Retrofit - LinuxCNC + EtherCAT

If you have 3-phase power available, running the 3-phase motor off line power might be a good option.

You lose speed control, obviously, but running off line voltage should be more energy-efficient b/c the VFD is not 100% efficient, nothing is.

Aren't 3-phase motors self-starting?

I thought only single-phase induction motors needed special starting windings/capacitors.

"Star/Delta" does not make sense.

Something is either Wye(Star) or Delta(∆).

(A transformer can convert between Delta and Wye, of course)

A winding cannot be simultaneously Delta and Wye.

Small update. When there is no g96 /G95 command in the program, the program calculates the approximate time correctly. Maybe feed per rev is not calculated correctly. Thanks for the great work! I understand that this problem is not in the field of gmoccapy

Hello EmilDLo,
mine is right now working with your config. I can start it up to explicit RPM, change RPM and even stop without problem. I didnt change anything on your XML, Ini or hal, so your problem completly is in your VFD set up.

Thanks for that, nice touch having the interval/on times adjustable from the status page, very handy.

The WLED should be great for general status conditions and minor warnings at a glance, looking forward to adding some bling to my machines.

Cheers.
Russell.

I managed to resolve it. Turns out those boards are maybe not for the same type of encoder? The sin and cos were inverted and so were their + and -. The connector was also mirrored the wrong way. I managed to cross the DB15 connector pins in a way to get it to work, though, and I can happily report it's basically plug and play after that. All that's left is to play around with the resolution with the jumpers a bit...

a little tip on what you can do with the wled's to display the status:
        {
            "type": "wled",
            "pins": {
                "data": {
                    "pin": "WLED:DATA"
                }
            },
            "signals": {
                "0_green": {
                    "net": "(!halui.mode.is-auto and !axisui.error) or halui.program.is-paused"
                },
                "0_red": {
                    "net": "axisui.error"
                },
                "0_blue": {
                    "net": "halui.mode.is-auto"
                }
            },
            "uid": "wled0"
        },

in dev branch and untested (only via testbench):

github.com/multigcs/riocore/blob/dev/rio...s/interval/README.md

little config example 10 seconds on / interval 20 minutes default
        {
            "type": "interval",
            "pins": {
                "out": {
                    "pin": "PIN:69"
                }
            },
            "uid": "interval0",
            "signals": {
                "enable": {
                    "display": {
                        "title": "Pump-Active",
                        "section": "status"
                    },
                    "net": "halui.machine.is-on"
                },
                "ontime": {
                    "display": {
                        "title": "Pump-OnTime (s)",
                        "initval": 10.0,
                        "min": 5.0,
                        "max": 20.0,
                        "section": "status"
                    }
                },
                "interval": {
                    "display": {
                        "title": "Pump-Interval (s)",
                        "initval": 1200.0,
                        "min": 600.0,
                        "max": 1800.0,
                        "section": "status"
                    }
                }
            }
        }

looks like this:
 

and the onTime can be adjust between 5 and 20 seconds / interval between 600 and 1800 seconds (10 - 30 minutes)

i will add a new plugin named 'interval' or so.
then you can configure the on-time and the interval-time via gui/hal

RS485 Spindle Control was created by giaviv

RS485 Spindle Control

Category: Driver Boards

Hey,

I have a Mesa 7i95t board that to my understanding has support for RS485.

I want to connect my Delta MS300 VFD to LinuxCNC over RS485, and I think I have two options:
* I've got a USB RS485 dongle that I can connect to the PC and to the VFD on the other end
* I can connect the Mesa board's RS485 terminals to the VFD

Which one of these options are preferable? Are both these options correct, and are there any pros/cons to either?

Thanks!

Mesa Auswahl für größeres Projekt was created by G0G53Z148

Mesa Auswahl für größeres Projekt

Category: Deutsch

Guten tag zusammen,
Ich wende mich an euch weil ich den Anschluss vor lauter kabeln nicht mehr sehe.

Konkrekt geht es um 
4 x Step-Dir Servos
1 x -10 bis +10V Spindelservo
2-3 0-10V Spindelservo
8 Eingänge für je 2 Achsendschalter
4 Ausganänge für Bremsen

dann noch Aus und Eingänge für Allfälliges 

Die erste Kombi die mir eingefallen ist war 
7i92TH
7i77
7i90HD
7i85
die 7i77 und 7i90HD kann man über IDC26 P1 und P2 mit IDC26 -> DB25 verbinden
aber dann hat die 7i85 noch keine ansteuerung. Kann ich die auch an die 7i92TH hängen? wenn ja wie bitte oder braucht die 7i85 eine weitere 7i92TH

Das war so mein gedanke 
was würdet Ihr verwenden oder einsetzten 

Danke mal wieder für die hilfe und schöne grüße aus Österreich

7i92 pwm to 0-10v analog

Category: Driver Boards

i found a solution that worked.
i change inside my inverter to 0-5v input and adjust the potentiometer on the china pwm to analog pcb.
then i change the scale in the hal for the pwm.

50% 12000 rpm 203hz
100% 24000 rpm 400hz
75% 18000 rpm 305hz
25% 6000 rpm 101hz
12.5% 3000 rpm 49hz

it works for me

thanks guys

Trouble with LinuxCNC and Gantry stepper motor setup.

Category: Computers and Hardware

I do. I was able to get the Z stepper working, as it had a low voltage issue and was only able to jog in the up direction when I clicked on the jog arrows in config wizard. was also able to find the gantry config in the config setup when I opened Linuxcnc app. I am now needing to locate a helpful tutorial on Homing the joints. Have not found any yet. Can not do anything until this is done.
