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.
