LinuxCNC-RIO - RealtimeIO for LinuxCNC based on FPGA (ICE40 / ECP5)

Category: Computers and Hardware

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

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

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.

Actually, now that I have done more testing and fixed on issue in my ini file (had HOME_SEQUENCE=1 for all joints instead of 0), my original instructions at forum.linuxcnc.org/ethercat/54908-missin...-homing-lc10e#318671 appear to work correctly for homing LC10E drive with an external home switch on DI2.

I thought you had a parallel port setup ( using stepconf to create configurations )

Category: Installing LinuxCNC

Hi, can you detail how you managed it, since other users have had problems? I'm having problems with rtai-modules-5.4.290_5.3.3-linuxcnc_amd64.deb
Another detail is that when I try to remove linuxcnc, I get another error. It says: Sub-process /usr/bin/dpkg returned an error code (1)
 

Guys, I found here what I needed to solve the problem, but when I open LinuxCNC, the screen goes black and restarts to the user login. However, I don't know if this is normal or if there is a problem, so I prefer to restart the machine.        forum.linuxcnc.org/9-installing-linuxcnc...ue-with-2-9-4#327437

Awesome thank you, I'll update and check that out tonight. 

I don't want to push my luck but would it be possible to have a dual timer plugin? It would be for lube pumps mainly, so generally they turn on when the machine starts, run for 10 seconds then off, and turn on for 10 seconds every 20 minutes after that. 

I guess the blink could be modified for longer frequency but both the on and off time needs to be adjustable.

Cheers.
Russell.
