It does seem that the American electrical system is the culprit as almost all of these issues seem to occur on 110V.

Ahmad H. is in Kuwait which uses 220 volt, and says the SSP EG-1 LS burrs are unusable due to stalling. So I'm definitely not convinced it's a power issue.

I couldn't find any details on webers website, but doesn't the driver box convert to DC? The grinder wouldn't know whether it's connected to 120,220 or 240.

The post I replied to mentioned CORE burrs stalling so that wasn't related to the SSP LS burrs.

I do think it's more a burr problem instead of a grinder problem as the orignal LS burrs just work fine on the EG-1. Has someone tested these burrs on other grinders with good results as I haven't seen that? And then I mean a grinder that isn't a huge shopgrinder and 3 times as big as an EG-1.

SSP just made a mistake here. We can also make a burr that grinds 18gr in under 1s and will tear apart a whole grinder but blaming the grinder for that wouldn't be fair. They just went a bit too far with these burrs.

I haven't used the blind LS burrs, but I've used the regular LS burrs in my Wug with the RPM turned all the way down and can still grind fine enough to pull blooming shots from a cold start. I've also ground at chirp on 80HU without the RPM dropping at all. Installing a blind carrier soon so will get to see how they get along with more burr surface area.

Which burr listed on espressotool.com is the holed version of Weber ULF?

Thank you and apologies if it's already been discussed in the thread, there's a lot to get through.

Looking over the page, I would not recommend ordering any of those because I suspect none are the correct ULF equivalent ones. Supposedly the 80mm HU = the Weber ULF ones. 80mm burrs, with Silver Knight coating, are the burrs I ordered directly from SSP via email a few months ago. I am not sure which one, if any, listed on that site are 80mm HU.

I wonder if there is variance over time where the more recent grinders are more prone to stalling.
I have my EG1 about 18months now. I am on 240V, and I can stall the Core Burrs whenever I want. Any bean dump of 18g into the running grinder, at 1000rpm or lower, of the light to mid roasts I use (Sey -> TW -> 3FE is probably the range of lightness) will stall the grinder.
I work around that by slow feeding, not super slow, but over 1-2 seconds.

The ULF burrs seems to be less prone to stalling, but I have managed to stall them also.

After this time with my grinder, I find it difficult to believe that you have never stalled once in 4.5 years, unless your beans are significantly different, or the electrics of your grinder are different to my model.
I do not doubt your statement, but I wonder how your experience with the EG1 is different.

I love the coffee from the EG1, from my EG1, but it is not as "perfect" as I would wish for for the price I paid, and that one imperfection is the stalling and fear that arises from the stalling.

Great Coffee though.

Hi All,

Does anyone know if there are lab sweet 80mm burrs (either cast or steel) made by ditting (not SSP), but of the blind variant. I'm looking for the kind you could install in an 805 or Tanzania. I don't think such a variant exists, but I'm not sure. Thanks for any info. Thought this was still pertinent to this thread.

I've had a subscription from TW for 3 years so most of the beans that went through my EG-1 are from TW. When I order somewhere else it's mostly La Cabra, Friedhats etc which roast like TW. I always dump everything and have gone as low as 300rpm and never any problem. So my beans from a roast level perspective are the same as you're using. I dump and start the grinder at the same time and have forgotten to turn the control box on for at least 30 times and even when I cold started it with the beans already in there it's never missed a beat. Mine is just bomber for anything you throw at it.

I would also be disappointed if mine would stall after paying this much for a grinder but it just never happens. Well, I must be lucky mine doesn't do this.
