Oh, and the manual fits perfectly in the binder:

Just to touch base — I’ve been doing a lot of testing, which has involved a lot of tool changes, and the Mafell Quick Change Spindle has been working perfectly.
Did have one disconnect which I’m attributing to the transformer — hopefully I can get things re-arranged a bit so that it’s not so close to the electronics.
The other consideration is that the Mafell FM 1000 WS version is no longer carried by Timberwolf Tools — apparently it will be replaced by the FM 1000 PV-WS model:
(which brings us full circle)
It would be pretty cool if someone could document what is involved in connecting that to the BitRunner connector on a Carbide Motion board — even cooler if Mafell would work up a 110V unit.

sounds like it has a “0-10V portal control”, so it would probably boil down to procuring the correct set of connectors, and a 0-5 to 0-10V voltage shifter to insert between the bitrunner connector and the portal.

If it’s 0-10V it’s probably analog, and you can get cheap PWM to analog voltage converters from the usual suspects. ( https://www.amazon.ca/Baoblaze-High-quality-Voltage-Converter-0-100/dp/B07CNRWB2C). The ones I got from AliExpress can accept a wide range of PWM input.
You will need to set the min/max spindle speeds, some light unverified googling says $30 and $31 will set this. This will then control the PWM output for a given RPM and “map” it appropriately.

A bit of an update on this.
I was warned when the step-up/down transformer was suggested that it was a heavy-duty unit which could potentially burn a house down (or maybe they meant that no using this could cause that)…
anyway, I usually unplug/turn off the dehumidifier when running the CNC, but the other week I forgot — as near as I can figure, both it, and the spindle came one at the same time, followed by “the magic smoke” and half the outlets in the basement going dead.
Turns out the basement wiring was bridging from one outlet to the next using the outlets to carry the current over, which was too much for the outlet feeding the outlet the dehumidifier was plugged into — burned out the outlet, but the appearance was quite terrifying.
An electrician pretty quickly sorted out, and we scheduled a return trip to wire up half the basement outlets on their own circuit, and to put in a separate 20-amp circuit for the spindle/vacuum — finally got all that done this morning, so back up and running.
Recommendation: if using a spindle which has the potential to make a very heavy current draw, get a separate circuit run for it, and future-proof it by making it 20 amps.

With the 20 amp circuit breaker #12 wire and outlets rated for 20 Amps. 15 amp standard outlets an #14 wire are not rated for a 20 amp load.
This is for US 120 vac.
Yeah, not sure what the step-up/down transformer was actually pulling — hopefully the dedicated circuit will be workable.
With a transformer if you step up voltage you step down current on the load side. If you step down voltage you step up current on the load side.

Since this was introduced, Mafell has expanded their collet adapter options and now offer an official 1/4" collet reducer:
Adapter sleeve 1/4" (6,35 mm)
ground
for FM 1000 WS / PV-WS
Ref. No. 207947
I’ve drawn up an adapter plate for my SO5 Pro, so hopefully this will get moved over presently, then I’ll set up my XL for metal-working (don’t want to scratch up my nifty Sweep Pro on my SO5 Pro) and will set up my SO3s for cutting tropical woods outside.

Also, I’ve been debating about mounting this on my SO5 Pro — towards that end I drew up:
SO5_Pro_mount_ADAPTER_Mafell.c2d (608 KB)
SO5_Pro_mount_top.c2d (44 KB)
no promises on accuracy or workability (haven’t even cut a test fit in acrylic yet).

Do I need the pro version of Carbide Create?
I downloaded the files and tried to open them, the page is just blank and there are no toolpaths or anything.
Totally my fault, sorry.
I’d downloaded the never version but hadn’t actually installed it!
Works fine, user error.
Reworked the mount file a bit:
Modified the file to what I believe is the correct hole spacing for the mounting to the SO5 Pro plate — measure and check against yours before committing:
SO5_Pro_mount_ADAPTER_Mafell_13_5_thick.c2d (608 KB)
and cutting now:

And after a bit of cleanup and opening up the holes, it fits:
Next we resolve dust collection (hoping to be able to make use of the Sweepy Pro).

The Sweepy Pro will require major modifications to work, but we’ll look into that when we get a chance.

Hey modifications is what we do. Everything is customizable and customized. Aluminum is just too messy for me to want to machine. Wood is bad enough. Glad you machined the alum so I dont have to.
Nice early Christmas present for yourself.
You have a lot of write ups for your Mafell Spindle. After all your work what do you think about it?
It’s annoying to have to make the adapter plates (and this time, I’ll need to get some Birchwood Casey Aluminum Black to finish it — if I bother to pull it and actually finish it).
The sound is rather different from the Carbide Compact Router or Makita — the pitch seems to either be something which falls in the range of my hearing loss (too many hours wearing headphones when I was in the Air Force) or which my hearing protection is esp. good at blocking out, so a bit more tolerable for long cuts
Further complicating the mounting is dust collection — I’m back to using a Sweepy v2 bottom and adapter plate, which while workable, doesn’t afford the wonderful adjustability which the Sweep offers — I’m probably going to take a hacksaw to my Sweepy Pro plate (or fabricate a replacement), we’ll see.
I think it has lower runout, at least than a Standard Carbide Compact Router, not sure if it’s the same or better than an ER-11 unit, and should have more torque, and it will run w/ torque at lower speeds — we’ll have to see if I do any projects where that comes into play.
It’s a bit of a workout to move the transformer around — it’s a quite dense and hefty 48 pounds, and the clicking from that being switched by the BitRunner relay is a bit worrisome.
It was quite expensive — rather an indulgence — the only way I could justify the expense is there were some days when I do so many test cuts for tech support purposes that it felt as if I was spending more time wrenching than the machine was cutting.
The quick tool change is of course the big win, but if one gets an ER-11 collet unit, that’s really not that bad — I’m not under a time crunch, and I’m not inclined to rush a tool change and risk cross-threading — if I weren’t doing so many test cuts, I probably wouldn’t’ve bothered. The lower runout and greater torque are nice, but I use the default feeds and speeds, so probably won’t take advantage of that aspect — unless of course @wmoy works up new feeds and speeds for spindle-equipped Shapeokos which coincidentally work with this unit.

One other thing is I pulled the mount and added countersinks to the lower mount holes for the unit on the back — hoping this will reduce the amount of cutting I need to do to my Sweepy Pro to make it work.
