Re: 2nd build - For a friend
Worked on finishing up the fixed plate for the Auto Tool zeroing. This fixed plate travels on the Y axis riser and it is outside work area. I was planning on doing this from the beginning and it's why the gantry is extra long. On the first router I made the fixed plate was on the back corner of the bed and it seemed like it was always in the way. I really like the auto tool zeroing I just didn't like working around the plate.
So for this build I cut a block out of cast nylon and made it fit over the bolts and bolted it to the riser. Cut a pocket out of it and cut an aluminum plate to fit in the pocket. The plate sticks up about .010" above the block.
The tool zeroing macro disables the software limits when it's called and then re enables them after it's probing is done. It's not quite perfect; when it's last probe is done and the Z axis retracts, it stays above the plate and re enables the soft limits. The problem is it's outside the limits.When you command a move back into the normal work area it trips the software limits. Minor issue that is easily fixed I'm sure, just ran out of time today.

Ref Modbus; it's looking way to complicated. If I tried it I will be almost completely dependent on the work of other's. Still on the fence. Thanks to all for the info.

Hey 1Jumper10,
Third time posting here but first time reading through thread...Sorry!
Very nice build and professionally done, will continue to follow.
WhiteWolf, I haven't any experience with using Ethernet for communicating Modbus, but with a brief look it seems the Hitachi WJ200 is going to require an addon board from Hitachi to accomplish this, and its not cheap.

Re: 2nd build - For a friend
Dan911 - Thanks. Post all you like, there are lots of members here with valuable input. Yours included.
So if I'm going to use modbus on the Hitachi VFD, why can't I connect to the RJ 45 port right on the front?

Re: 2nd build - For a friend
That port is RS-422 and should work fine, here's a member who done it that way but don't remember where I downloaded. But its not TCP, its just a RJ 45 port/jack.
After taking a look at converter WhiteWolf purchased I'm assuming its taken the Ethernet signal than converting to RS-485 to VFD ?
Re: 2nd build - For a friend
I thought the same thing, the Hitachi requires an addon board for network communication, it plugs right in where the cover for electrical hookup is. It is not needed though and seems rather simple, the Amazon link I posted is simple device. It is a serial over ethernet server. Basically you wire two wires SN and SP connectors on VFD.
The instruction manual for the serial server is dead simple, if you can connect a computer or UC300ETH to lan then you can connect this device.
Then you use Dan911's UCCNC plugin which automatically takes care of the macros for you, no programming needed. Similar to the ease of the UCCNC screenset you already setup. (Note I have not done any of this yet but it really seems like the least daunting task of setting up the CNC thanks to Dan911's plugin

Re: 2nd build - For a friend
There seems to be a few different options with the Hitachi... it can be wired with the two terminals i spoke of in my last post or using a RS-485 mini usb to USB or serial adaptor cable from the mini usb port on the front of the VFD. Or a RS-422 RJ 45 to USB or serial cable from the RJ45 port on the front. or you can get the addon board which has a true ethernet port on it and it uses an ethernet cable from addon board to network switch. Or you can use the serial over ethernet device i linked to on amazon.... options options options

I recommend the https://www.amazon.com/USRIOT-USR-TC...SR-TCP232-410S ... its just two wires from this device to SN and SP on VFD... then plug the device into your router/switch with an Ethernet cable just like you did the UC300ETH. Install Dan911's UCNCC plugin and you're done. With this setup if you don't have to worry about interference and you can remote monitor from any device on your network and it is a lot cheaper than the Hitachi add on board.

Re: 2nd build - For a friend
I'm not using a router or network switch. It would go directly to the control computer. Which only has one Ethernet port and it's already dedicated to the UC300ETH. If I do it it would be from a USB port on the computer to the VFD. What would that need?

Re: 2nd build - For a friend
You can add an Ethernet card for about $15.
For USB, you need a USB to RS-485 converter.
I have a Huanyang, and if I find that the analog from the MB2 is not good enough, I'll probably go Modbus as well.

Re: 2nd build - For a friend
I ordered my MB2 last night. Looks like I'll give Modbus a shot as well. I forgot how easy it was to add a network card.

Re: 2nd build - For a friend
I bought a used card from a local EBay seller, for $10, and run my UC300ETH on it, and use the built in ethernet port for my network.

Re: 2nd build - For a friend
I'll probably go the USB route. I know its more susceptible to interference but I think I can isolate it well enough. That, and the mini-computer has USB ports to spare. Ya'll get it figured out so when it comes time for me to do it I'll just have to upload your plugin's and hit start!

if you are going USB, this one appears to be noise isolated https://www.amazon.com/EZSync-RS485-...ords=USB+RS485
you can get a used industrial router for $11 on amazon for ethernet method then just plug your pc and both devices into it, no configuration required. If your PC is on your home network then use a switch instead which can be had for $5 here is an industrial router: https://www.amazon.com/gp/aw/d/B0000...P1L&ref=plSrch
Re: 2nd build - For a friend
So with MODBUS control of the VFD, is there something like a dashboard on your computer monitor that displays parameters like spindle status, current and RPM? Is it a display within UCCNC? Just trying to get an idea of something that I've never considered before.

Ger and Whitewolf thanks for all your helpful links and suggestions.

Re: 2nd build - For a friend
The monitored values will be displayed as part of UCCNC through changes in the screen set. I have not yet implemented this in UCCNC due to other priorities (just tested) but done it in similar ways in Mach3. I will also upgrade the M3 and M4 macros so that the real RPM is read and the G code will not continue from M3 and M4 unless the set RPM is equal to the one reported by the VFD. This eliminates the need of fixed delay after M3 and M4 commands.

Re: 2nd build - For a friend
That's an advantage. I spent a lot of time researching Modbus over RS485 last night. I guess I feel like if I'm going to the trouble of implementing it, I want it to do more than just adjust spindle speed. I want some feedback from the VFD.

Re: 2nd build - For a friend
What feedback you can get and how is up to the VFD. Not all VFD allow reading of RPM for example. The UCCNC Modbus plugin which is delivered with the product support reading parameters but what you do with it is again up to you. Once I am starting the implementation I will document it. Done some tests before and that looks promising.
