Recent Versalab M3 performance

Postby Peppersass on Fri Sep 04, 2009 6:15 pm

I have an LM GS/3 and I will be upgrading from a Macap M4 soon. The Versalab M3 is on my list for consideration. I'm well aware of the controversies surrounding the manufacturer and early production models, and I don't want to get into any of that here. I simply would like to hear from anyone who has used a Versalab M3 grinder manufactured within the last 1-2 years on the following questions:

1. Does the grinder produce consistent high-quality output over days, weeks, months of use?
2. Does the grind setting slip?
3. Does the drive belt slip?
4. Have you observed burr misalignment?
5. Have you observed runout in excess of spec on the drive shaft?
6. Are there any other design or mechanical flaws of which I should be aware?

At the moment, these are the only questions I'm interested in. I will later post my set of requirements for a grinder and ask some questions about which grinders may or may not meet them. For now, I'd like to know how current M3 owners are faring with recent production models.

For me, yes.
2. Does the grind setting slip?

When I first got it, I would sometimes forget to tighten the grind setting clamp. I have not made that mistake in over 6 months.
3. Does the drive belt slip?

For me, never. I rarely grind light roasts, but I have done so more than once.
4. Have you observed burr misalignment?

No.
5. Have you observed runout in excess of spec on the drive shaft?

No.

The main bearing was not glued properly when the M3 was first shipped to me. That was fixed quickly. My anti-static wire broke at some point, but I have noticed no buildup of coffee, so I haven't replaced it.

Best,

Matt

My unit has been working fine for 6 mos now. I have not had the belt slip, and I pour the whole load of beans in all at once. If a hard, light roasted bean is a problem for the belt, I would think that can countered by pouring the beans a little at a time. - Dennis

I've had mine since early '06, so this is outside your sample, but:

Yes

Peppersass wrote:2. Does the grind setting slip?


No, it actually requires less adjustment than the mazzer roburs I've used, probably because there's so much less heat.

Peppersass wrote:3. Does the drive belt slip?


Yes, even when recently cleaned with acetone. I bought the "knurled pulley", but it made very little difference. I don't use unusual beans; i regularly alternate between Stumptown, Ecco, Ritual, and whatever else strikes my fancy at Barista- the belt slips on any of them. I feed beans slowly, but its still an issue. When I finish my pump project I might look into timing pulleys & belt (a sim. solution to what Mark at Synesso has in his shop.)

No.

I've never put machinist tools to it, but you can see very slight eccentricity. I see no impact on performance, though.

I've blown a fuse on it once when feeding unusual beans, but its an easy fix (with spares included with the grinder) & they're easy to source for replacement.

I've had mine since April of this year and it has made a huge difference in the quality of my espresso. Consistent excellent grinds and pours. I often have 5 or 6 SOs and blends open and change between each cup. This grinder has been perfect for that. I keep notes on the various grind setting for each blend and adjust between each cup as needed.

1. Does the grinder produce consistent high-quality output over days, weeks, months of use?

Yes


2. Does the grind setting slip?

No, not at all unless you forget to tighten after changing.


3. Does the drive belt slip?

No


4. Have you observed burr misalignment?

No


5. Have you observed runout in excess of spec on the drive shaft?

No


6. Are there any other design or mechanical flaws of which I should be aware?

None. The unit did ship without the portafilter holder I had ordered but they shipped that out a few weeks later.

Yes


2. Does the grind setting slip?

only when I 1st bought it. It never has after I adjusted it.


3. Does the drive belt slip?

Yes, but only with lightly roasted beans. Keeping the belt clean and replacing it once a year helps.
I think a cogged belt/pulley system would make this a near perfect grinder at least for me.

4. Have you observed burr misalignment?

No


5. Have you observed runout in excess of spec on the drive shaft?

No


6. Are there any other design or mechanical flaws of which I should be aware?

No.

You might be interested to know that the brass parts are not clear coated, and therefore not as easy to clean as chrome or stainless steel. I use Mothers metal polish on them every other month to keep them looking like new.

Doug, I see you are online.
Are you interested in Dr. Beans cogged pulley set? I saw the inquiry on his blog.
I translated his price to be $91.34 USD + shipping. If we both buy, I'll split shipping with you.
