Have you seen http://www.imenista.com/pdf/XDXDM%20instruction%20manual.pdf page 288?

I have no experience, but seems to be a reasonable google-hit.

The copy of the manual I found online suggest pin 61 is a +12V (10mA max) regulated supply. Check that is +12V wrt the common rail (99.9% convinced it will be) then use that +12/Com as the HV supply...

https://industrial.panasonic.com/content/data/MT/PDF/MINAS-Xseries_manual_e.pdf is my "source of truth" here - please confirm yourself that it's applicable to your servo drive.

From that link,...

Final comment from me then I'm going back under the rock for 6 months. The control inputs to the HY VFD are fed each though onto-isolators on the control board internal to the VFD. You already have...

The Arduino-based controllers/drivers have been designed around the original 3d-printer designs, capable of driving the small NEMA-17 stepper drivers which provide relatively low torque. The firmware...

If you want to take this IM please feel free to do so, this isn’t the place to iterate a design. Hint: consider how you’re going to support a differential drive from the encoders, if someone was...

Please do me a favour and design your hardware to behave in a robust and dependable manner within the environment that you're advertising it. Don't think for a second that a RC filter will protect...

Welcome - as a ML7 CNCer I'd be interested in following any threads on your conversion plans.

Looking good. Just a passing, friendly thought - if you've not got/planned it already - it's generally recommended for a little air-assist, particularly with composite materials, so when you ablate...

A useful reminder to me to not ignore/assume the basics

Not what you want to hear - but almost certainly better to replace steppers with closed-loop.

You *could* attach rotary encoders onto each screw and - not sure of any COTS solution - knock up an...

You've not yet earned that soapbox.

Woodknot, with the greatest respect, you came here asking advice, and received some good, informed responses, and you are in the process of ignoring much of...

Hate to say it but I'd be thinking of "letting go".

There'll be one chip that does all functions including the LCD drive - if that's borked then....

Not another bloody Aussie!

Welcome onboard.

Welcome!, it sounds as though you've learnt a lot over your introduction and I (and I'm sure many others here) will be interested in your thoughts and design of a new machine.

That's exactly my intended meaning. Whether my meaning is right or wrong... but I think it's right. I normally get a "ignore-me pester box" whenever I import g-code from Fusion that typically...

Son, I like it, quite well built for the price, with readily replaceable probes. Repeatable to 0.01 on mine according to UCCNC. But isn’t pre calibrated. It’s certainly good enough for what my needs.

THIS!, eyeball the axis broken down as a sanity check!

I don't remember grinding my nuts on the Y, but defo on the X.

In seriousness - I've read and tend to agree with the general philosophy - ground both ends on an emissive line (steppers, spindle) - you really don't care with those and it helps avoid these...

I've come across this from another site...

Yeah, you can short VDD to +5V - that will allow you to run on a single PSU. You don't get analogue spindle control (but neither does your other...

4. Some drivers will take AC or DC supplies (nothing special - they just have a rectifier to take whatever and make sure its DC internally. Normally there's a smallish cap inside to smooth the...

1. AXBB is fine. I use a UC300ETH on my SX2.7, but only one port (a second port controls, separately, a Starmill).
2. Go Digital drive!, I've used 2DM860Hs but there's plenty out there. I'm sure...

Just to pick up on some points...

Hardword or Aluminium.... journal bearings? are you sure?

Journal bearings at the accuracy that you're looking at (3 micron) is a job for a rigid lathe and...

Okay, I've spent 2 minutes on the Makerbase website and given up - have you got instructions for the board, and in particular which are the A+/A- and B+/B- terminals on those 4 way plugs?

If so -...

Then keep a fire extinguisher handy :)

You'll lose coherency on anything other than a polished surface, the amount of energy reflected back into the LED - there'll be some, but not a huge amount. ...
