Here's one with it cutting wood.

I remember that feeling. Don't get stuck in all the conflicting info. It's actually very simple.

Exactly. I was providing one example of why the statement "there's no point in larger motors if you don't have 3ph power" was not accurate.
Larger single phase motors wouldn't exist if they...
I don't have any expectations of perfection (especially not on a sub-2000lb diy machine).
It's really more about not adding additional problems.
People running small belt drive spindles may not...
Nema 24 do not fit nema 23 mounts. I used NSK linear actuators for my first build and they came with Nema 24 Yaskawa AC servos.
It was really annoying because I couldn't simply drill new holes...
Not that it matters now you already ordered your VFD but read this if you want more comfort on the running a 3 phase spindle from 1 phase power:
...
Our spindles can be run on either 220v or 380v. If you look on the inside of the junction box (where you connect wires to the spindle), you'll see six screw terminals with some of them joined by...
Who is "they"? Z Germans?
I don't remember seeing any VFD inspectors when I lived in the UK.
Have you seen an actual (official) list of rules for what VFDs people can use in their own home...
I know... But we're talking about VFDs for spindles...
Almost all VFDs are 3ph input even if they advertise 1ph in (or 1ph or 3ph in). That includes those HY VFDs.
Almost any 220v 3ph VFD can be run on 1ph 240v. That includes the ones I sent you...
That PDS ADEV 90 is a manual tool change model. They do make an ATC version but it's closer to $10,000. The one in the listing is ER25.
One upgrade you could make is switching the shaft fan for an...
Hiteco, PDS, Colombo are all broadly comparable. Hiteco spindles are cheaper than PDS and Colombo, especially on the ATC side but I'd be happy with either.
You can see how much they go for new...
For future reference, I get that error on an HY vfd when there's a short circuit or a wire pulled loose in the spindle.
I had the issue at the beginning before I learned to secure the vfd cable...
There are bolt-on ATC adapters for regular MTC spindles but the ones I have seen max out at 2.2kw.
More importantly, they are all either awful or too expensive to be worth it compared to just...
You need flexible shielded 4 wire cable (or 6 wire if the spindle has an electric fan) and it needs to be sized for the number of amps.
Look at the spindle name plate to see how many amps it...
PDS and Colombo are a different brand although PDS in America seems to do the distribution for Colombo.
I'm not sure if they have the same parent company but they definitely have their own...
I thought it was still in the planning / pre-purchase phase too.
The parallel port on the Gecko side is just a port for connecting step and direction wires. It can be fed from other sources at...
I use LinuxCNC and I'm definitely not a programmer, nor is any programming required. After the initial install you'll spend almost no time in Linux anyway.
Linux CNC itself comes with an extremely...
For wood and some occasional aluminum that spindle is fine as long as you don't need it to be quick.
Despite it's label it's not a particularly powerful spindle though. You'd be limited to small...
I cut aluminum and wood just fine with 465 oz/in and 381 oz/in stepper motors on 48v via a Gecko G540 with linuxcnc.
They're more than capable of exceeding any feed rates I could realistically use...
Their "high torque" label is a little misleading. They use it to describe their spindles that hit peak horsepower at 12,000rpm instead of at 24,000rpm. They have double the torque up to 12,000rpm but...
Yeah I've been going around in circles in my head on this. It does look like it has a small shaft given the bearings it uses. This slightly more expensive 30 taper one uses larger bearings:
...
Even if they put a number I wouldn't trust it. In my experience, you guys are a far more reliable source... assuming I can find someone here who owns one.
Even the "reputable brands" can be hit or...
A family member wants to buy my next spindle as a gift and these low end ATC spindles are within budget.

I saw that it keeps my last setting (in Fusion). That's nice so I won't forget a break more tools.
Once I did the two things you suggested it all worked like a charm. Thank you! I really appreciate it.
I really don't remember needing to set it to "clearance height" in the post menu last time I...
I was just looking at that. There's a bunch of settings in the post processor menu that I usually ignore. The drop-down menu for safe retract height defaults to G53.
If this overrides everything...
The simulations don't help here because everything looks perfect there and it shows no crashes. But, it shows no lead-in.
Also, after the initial dragging the tool through the side of the stock...
How do you guys program the lead-in when using Fusion 360 for Cam so that the tool doesn't get dragged through the side of the part at the start of a job?
I've been having problems with this...
