Hello,
have you seen this: https://www.youtube.com/@RapidChangeATC ?
Can it work on our mk3/4 board with TNG V2 software?

It seems that what it needs is running gcode macros for loading/unloading the tools and the command to reverse spindle direction. Will it be possible with the HY VFD?

I was following that project and am curious as well as to what it would take to get it to run with Planet CNC TNG software.

With some minor changes to ATC script this will work with TNG.

Hi Johnny,
The Huanyang HY series is the only one I use on all my machines. I am sure other VFDs will work also but we are able to fully support the HY series. We are also very committed to our customer support.

Thanks, I'll try it! Is it something I can do myself when I have it all set?

[PlanetCNC]

Yes, you can do it yourself.

[JohnnyDanger]

Thanks Don, I know that you are doing a great job in supporting your customers. I just wanted to be sure that there wasn't something blocking me from trying this on TNG. I'll be soon be one of your customer for the Rapidchange and hopefully one of the first to have it running with PlanetCNC TNG.
As soon as I have the new spindle mounted and working on my router I will pull the trigger and order the rapidchange basic kit.

[JohnnyDanger]

Yes, you can do it yourself.

Great! Hope I'll have your support when I am doing this...

Now, to have everything ready for this, I have a few questions:

- Do I need to connect via Modbus/rs485 to the VFD or can I do it with the simple output board signals?
I have checked and my vfd (Sako SKI780) can switch direction from an external input. It supports Modbus-RTU protocol too, but on the manual it's not detailed in any way.

- I have a mk3/4, it means that I need to buy your Output board to control the spindle with 0-0V speed signal and start/stop for/rew, right?
The board seems to have just 2 relais now, so I am going to use them all for the spindle.
So, If I need to control other devices (vacuum, lube pump, coolant pump, etc...) how can I do it?

- One last thing. While I am on it, what do I need to buy use inductive sensors for homing?

Thanks!

You can use Modbus, but I would advise against it if your VFD does not come with great and detailed modbus documentation. If you would use Modbus, you can see more info on how to implement it here:
https://planet-cnc.com/modbus-commun...ang-vfd-part1/


You can use Output board34 for spindle VFD control:

For connection of inductive prox sensors you can use this Limit adapter:

I have studied the tutorials and it seems doable, but the SAKO SKI780 does not detail the Modbus protocol it uses. So, for now I'll use the Output Board 3/4 I have just bought.
Bytheway, the RS485 adapter does it work on the Raspberry Pi too?

Can I use the ExtInOut board instead? I bought that too because I want more output to control flood, mist, etc...

Please ship it fast. ;-)

Hi,
I'm also interested in getting a RapidChange ATC and getting a Planet CNC mk3/4 board. I want to use the board with a dual motor Y axis machine, can I use one set of axis outputs to control both Y axis drivers at the same time? I'd like to be able to use the ATC dust cover motors. What would the best approach be if I can't use both drivers from a single axis output? The tool change macro could manually trigger an output to pulse the stepper, or use an NE555 board to pulse for a duration of time. Can planetCNC use rpi GPIO pins?
Thanks

[PlanetCNC]

HI,

You can connect two drivers to a single axis output of controller, but you can also use dedicated axis output for slave axis.
In first case you can use script for toolchange where you could configure free axis output of controller for dust cover motion.
In second case you can use external device to control the dust cover.

[JohnnyDanger]

Rapidchange ATC is finally arrived. I'll start mounting on my router and post some picture of the integration.

In the meantime:

Is this true? Can I use this board on Mk3/4 to connect npn proximity sensors to limit inputs? Can I use the extension board inputs as limits?

[PlanetCNC]

Yes, but you'll need to wire it yourself because Mk3/4 uses screw terminals and this board does not.

[JohnnyDanger]

Ok, I have bought new PNP proximity sensors and I will use your optoiso 3/4 adapter.

[JohnnyDanger]

I am almost ready to install the Rapidchange atc magazine on my router, and Don just posted a configuration package to download and did a live tutorial for Planet CNC users!

Timing is perfect, I'll start to try it soon!

[JohnnyDanger]

Here is mine, working perfectly!

If someone is interested I can post my settings...

[PlanetCNC]

Thank you for this video.

[JohnnyDanger]

Thank you for this video.

You are very wellcome. Next I'll wire the tool sensor, test it and report back what I find... For now it works OK, with plenty of tightening torque.

The only thing I can think of now it's having a "safe zone" or safe height for a specified zone, so that you can not move and crash into the magazine.
