OK here is the next installment. I designed the Z axis to have up and down, touch off sensing, and torch breakaway. But I didn't like how it turned...

This is not a recommendation, just one data point from one user to get the ball rolling... My gantry router uses the ubiquitous 3HP 24K RPM Huang...

So I bit the bullet and ordered the Servo Motor Drives, Motors, and all the cables to match. Up until a week ago, I'd never even considered...

Again, thank you for the detailed explanation, I'll get some more research done my end, but this is looking promising. Thanks once again Phil

Incremental encoders output a basic Quadrature (A/B usually along with a Z index) signal, which is counted by the drive (aka the drives internal...

This is all great info, thanks so much! I've seen a 1000w 80 Flange from Lichuan on Aliexpress, I've asked the question if they can get custom cable...

Most servos above a few hundred watts are mains powered. NEMA simply refers to the motor mounting dimensions, and is an older imperial based...

Now that's just opened a whole new can of worms, lol, Servo Motors and Drives!? so from my quick Google they definitely seem like they're the best,...

The SDSK version please

At that size of machine, I wouldn't even consider steppers. You can get 1kw servos for well under £200 an axis, which would give you far better...

Hi m_c, thanks for the detailed info. Although it's a DIY build, it's a bit of a monster, 3000mm x 1650mm Steel frame with 9kw ATC (which weighs...

Plenty machines run unshielded stepper motor wiring, but those machines will also likely be running 24VDC control circuitry with some differential...

hello guys,the spindle position on the work table is different from what, on the nc studio sreen..how do i match the two....thanks

Yep. 5K is decent for what you have there. My 5 Axis Bridgeport clone has 4.2K however Im only getting around 3.9K at 50 Hz. Temped to take the head...

Perhaps best solution for machining time and surface finish would be a single flute, lapped cutter at max spindle speed (5000rpm for me), with full...

Yep, know the feeling. I think for Alu, Air plays almost more of a part than lube. Get them chips out ...

Sorry I don't recall the F&S but probably close to what the mfr recommended. I have about 4kW available at the spindle but it's not often I can get...

Nice cutting on what looks to be slowish Speed (due to machine). Whats your DOC and Feed Rate please?

I prefer uncoated carbide with honed or "lapped" edges (= razer sharp!) and the only issue I've had has been when using high material removal rates...

Thanks John for your reply, I'm going to go for the closed loop option I think, there's probably slightly more work involved in hooking it all up but...

For milling, HSS is fine. If you can find a tool with a carbide insert, it can work faster / harder but it is less forgiving, brittle and more...

I think the reason for shielding stepper wires is to minimise radiated EMY considering they are carrying fast high current pulses. IF the servo...

A UK supplier appears to recommend uncoated HSS for aluminium.

Any suitably sized servo motor should work. The driver is where you need to make sure that it'll do what you'd like it to. Key things are, are...

And does the Z work normally when using jog or mpg?
