How is the monitor connected?

VGA? DisplayPort? HDMI? DVI?

Maybe try a different resolution?

Those screenshots remind me of these screenshots of Minecraft looking really strange sometimes on my Dell XPS L702X with a NVIDIA GeForce 550M GPU.

Why is accessing Chrome necessary?

Check chrome://gpu

Consider submitting a bug report to Chromium, maybe they'll fix this.

You can also submit a bug report for Firefox, though in my experience they don't actually fix bugs.

I'm no expert, but connecting the VFD to the MESA seems right to me.

Try out both and see!

USB is convenient and inexpensive, but not really optimal.

"The Z Axis has a shock which creates resistance from it falling downwards."

If you remove the shock, what happens?

Does it fall under its own weight?

Is there any way you can make the Z-axis lighter?

(By removing superfluous stuff to reduce weight)

Perhaps you need a beefier motor on the Z-axis.

What is the existing VFD?

Can the existing VFD work with EtherCAT?

Why that specific VFD?

Why do you want to switch to EtherCAT?

What servo drives?

If you put the HDD from the old PC into the new one, it might just work as if the old PC never broke.

Try it!

You never know until you try!

(Though you can often anticipate the outcome)

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
