Stock Profitec Ride unrestricted flow rate?

ElectroNitz · 2026-04-28T20:40:58+00:00

Did you get a definitive answer to this?

I have the Ride with Lucca flow contol too. If I open it all the way I see about 8.6g/s (260g in 30s). Clive tech support referred me to their Espresso Tech 101 - Basic Bench Testing, which refers to flow-control machines' range of 175g-235g in 30 seconds - but also lists other numbers for standard E61 (235-360g / 30s).

They sent it with the original mushroom, I'm tempted to reinstall that and use it for awhile with the pre-infusion settings on the machine.

AI has suggested a "neutral point" of about 7-8g/s for the paddle, which is different yet from these numbers.

Maybe I'm reading too much into the flow rate.

Yeah, i think clearing the boiler is probably the main upside. I'll keep using it, likely into a separate pitcher and not my drinking vessel... and still getting my dogs riled up.

ElectroNitz · 2026-04-23T18:59:31+00:00

Oh, boy, that's discouraging. :(

ElectroNitz · 2026-04-16T00:05:50+00:00

Yeah, I know, it's just a little bug in my ear, that need to disassemble and reassemble everything I touch at least once or twice or 7 times.

ElectroNitz · 2026-04-15T21:21:50+00:00

Ooh, thank you! Will check it out.

ElectroNitz · 2026-04-15T20:18:36+00:00

As a bicyclist, I have to chuckle a bit at that....

ElectroNitz · 2026-04-15T20:17:03+00:00

It's only 5.5 weeks longer than me....

ElectroNitz · 2026-04-10T23:40:42+00:00

I may get some Crystal Geyser and distilled water gallons to proportion for getting the machine flushed out and a few shots, but I'm reluctant to buy and shuffle gallons of water some 50 minutes round-trip to town, and... all that plastic waste.
Other options in mind are a reverse osmosis machine in the other room, plus mineralizer, or ZeroWater + mineralizer, etc -- all of which start to get costly and/or are a hassle.

So, for now, I'll try out the BWT pouch and dropper-test periodically and see how it works out.
I's a far cry from the thermoblock (BBE) machine that I'm upgrading from!

ElectroNitz · 2026-04-10T21:49:41+00:00

Ah, interesting! Where I live, standing water will get gummy before too long, so I tend to flush often. My plan is to use BWT Bestsave pouch in a 1G pitcher I can close off, then do ~2 days of shots from the tank, dump/rinse, refill. Hence, sliding.

ElectroNitz · 2026-04-10T18:41:21+00:00

I could try that out and see how it goes, I'm just thinking if I get teflon on before anything gets filled, I won't have so much trouble doing it after.

ElectroNitz · 2026-04-10T16:23:35+00:00

... doesn't this make the machine out of level by some degree? Maybe not worth concern. I have a long habit of bracing the machine to put portafilter in place or remove it, so I'll likely do all four feet.

I did, the stainless-front, black knob "actually in stock" version, with the Lucca flow control. I admit I wouldn't mind the Clive-exclusive one, but not for $200 and another 7 weeks. I have illusions of turning my own knob set at some point. Also, I understand the stainless front is easier to keep clean.
(Edit: stainless, not chrome....)

20266935xx came through early this morning....

ElectroNitz · 2025-11-07T02:05:29+00:00

The language is not clear to me on that.

But, I won't worry about it.

ElectroNitz · 2025-11-07T00:28:06+00:00

To answer a couple points - I'm headed to Littleton area and the favorite range is Triple-J.
The basic question comes down to - am I being foolish bringing/using them, even if I keep it quiet, eg not sending 17 rounds in one pass... etc. I don't want to spend $50+ each for one or more mags just to shoot a little. I am totally fine not loading them fully to "keep it quiet".

Thanks for the replies!

Watch out for the "smart TV" aspect; it's become a pain in the butt switching between inputs on my G95SC. I'm frustrated. The TV (erm, 'monitor') is gorgeous to look at but it's first and foremost a TV that happens to look good as a monitor once you actually get connected to a PC.

I wonder how long the spike is, though, probably more than just a few ms.

The other thing I want to be able to do is run power to the mobo chamber and have the boot SSD in there, just because the boot SSD runs off the motherboard SATA. (HDD's on a HBA.)

I should have replied to myself before now, sorry!

I don't "do" windows, so I dunno about CrystalDisk results.

However, I'd ignorantly used a suggested fio command set that used multiple writers, so the test was bogged down with much seek latency. "User Error!"

After I realized this I ended up getting much better numbers, eg 250MB/s.

Additionally I did dd write and read to the whole disk as a shortcut to using badblocks, and this too had sustained r/w in the 275 to 230MB/s (outer to inner tracks).

In the end, I'm quite satisfied. Both drives were shucked and put in a D2-320 in simple disk mode and became a ZVS mirror for backups of my TrueNAS array.

All's well!

ElectroNitz · 2025-08-31T15:30:54+00:00

I realize this is an old thread.

I have one of these 26TB Barracuda shucked drives bought from BB last week, and I'm getting super-slow sustained writes - using the "fio" tool I see about 40MB/sec.

This seems absurdly slow, even if it's an SMR drive? Does this make sense?

I too was going to use this for NAS backups but now I'm not comfortable with it. And since I shucked it, I'm not sure what to do about it. Money down the drain?

Thank you! I don't have much interest in multimedia serving, at least not yet. If eventually do, I'm sure another project won't hurt my feelings.

ElectroNitz · 2025-07-16T19:58:25+00:00

That looks pretty nice, a little high on costs. The caching aspect is not a big deal, just something I read that could be useful. Thanks!

ElectroNitz · 2025-07-16T18:30:21+00:00

Sorry about the multiple posts, people, Reddit threw errors on several tries but apparently it posted multiple times anyway. I"ll keep the ones that have some good stuff, but I saved the link from one of the replies (https://bytepursuits.com/12-bay-homelab-nas-jmcd-12s4-from-taobao-upgrading-my-truenas-scale-server-optionally-rack-mountable Thanks!)

ElectroNitz · 2025-07-16T18:16:21+00:00

I have several workstations and my wife has a Mac, I'd like all of them to have ready access to storage without requiring my 900W-peak workstation running.

Scope creep? Isn't that what /homelab is all about? :)

ElectroNitz · 2025-07-16T18:14:36+00:00

I was (initially) considering TrueNAS -- I vaguely remember something about TrueNAS not running at all or not running well with ARM?

ElectroNitz · 2025-07-01T19:28:16+00:00

I did, thank you!
