Milo V1.5 BTT Scylla Motherboard Upgrade

[MrWillson]

I don't want to hijack your thread/conversation.  I was wondering if you could help me with my VFD and Scylla motherboard?  I have a YL620A VFD and I'm not sure how exactly to wire it to the Scylla board.  I'm nervous about getting that magic white smoke.  I've been digging around on google, and some of the YouTube builds for the Milo, but I haven't found much on it.  I have the rest of the machine working, and I can run the spindle from the VFD with the pot.  I would like to get the electronics buttoned up before I mount the machine on the stand and then start tramming it in.  Hopefully I will be able to afford the Casa enclosure in a few months, and then I can take it all apart and re-wire it again!

Thanks for your time, and any assistance

Not a problem, and welcome to the forum, you can use the same setting I've posted in this thread for my VFD. The labelling is a little different, but all matches up.

• AVR = Yours = 10V.
• PWM = Yours = V1
• SPD-GRD =  Yours = GND
• SP-COM =  Yours = XGND
• ENA =  Yours = FWD
• DIR =  Yours = REV

Remove G-SP, V-EN and V-DIR jumpers
Set Spindle Speed Jumper to AO

You'll need to change programming settings in P00.01 from 0 to 4 so that the Scylla controls the VFD speed and direction

I'd also suggest you join us on Millennium Machines on Discord, the inventor of the Milo V1.5 is on there, "Jake England," and "Nine Miles" the firmware contributor. Some great people on there are willing to help with no attitude.

Once you move electronics into the Casa, I'd suggest wiring it like the Milo V2, which entails adding a contactor for the VFD.

Found these documents on this YouTube video that may help.

Thank you so much for the help.  Sorry I've been incredibly busy, so I haven't been on in a few days.

Okay. I've wired it according to the information you gave me.  Thank you for that.  I pulled the G-SP, V-EN and V-DIR jumpers, and moved the spindle speed jumper to AO.  If I did it correctly, I changed the P00.01 parameter to 4, and after restarting it that setting stayed like I would expect it to.

The only thing I don't understand fully is the switches between the Fwd/Rev to XGnd.  Do I need a physical switch or is this done on the Scylla board?  When I start the Wizard (G8000) and it goes to turn on the spindle it doesn't respond so I'm not sure what I'm doing wrong.  

My apologies I'm not really an electronics or electrical person but I've been in Manufacturing for over 20 yrs, and I thought it would be cool to have a machine to play with at home.  That's why I jumped into this project without any real experience on the electronics side.  Also, I did join the Millenium Machines discord channel and have abused the search function like a mad man.  I dropped a comment in the #btt-scylla-v1 channel about the wiring for my VFD but didn't receive a response.  However, after a google search, I found this forum and more specifically your thread.  

Thanks again.

Regarding the Fwd/Rev that is done in Scylla. In Discord, ask your question directly to @nine mile with your VFD model, wiring connection, etc. He is pretty good at responding. I'd also mentioned that you had the spindle running from the VFD.

Then you're doing it right.  That's what this forum is here for.

I jumped into my Voron project with virtually no electronics or electrical experience. I dabbled in RC cars way back when (did just enough to plug components together and make a couple of nasty but functional solder joins to the motor) and did some electrical assembly in a previous job. The Discord channel and this forum were huge helps.
