Sorta proud? Well I drove To Bellingham from just south of Seattle at 500 this morning. Had breakfast with my son, then made it to the showroom about 9:00 AM. stared at lathes for awhile, then finally bought a G0632z. loaded it in my sur, drove home, assembled, then power. I was so excited! Then the breaker tripped. I figured out it trips when the rpm drops below 150 rpm. If I slow it down or turn the switch to off and it slows down on its own. no new shavings For me! 😬 Aaargh
Congratulations on your new lathe. I kind of wish I would have known more when I bought mine and I might have ended up with a swivel head stock instead of the sliding one I never use because of where I placed my lathe. Does it trip the breaker in either speed range?
I'm wondering if the circuit breaker is a GFCI (ground fault) ? If so, perhaps you replace it with a regular one. Some of the electronic speed controls cause the sensitive GFCI breakers to trip.
Make sure your electrical circuit is of proper amperage, use regular outlet, not GFCI, as Brice stated. A lathe with an inverter should be on a dedicated circuit for just the lathe only, and ideally a 20 amp rating. If I recall correctly, the G0632z has a 2 hp motor, and is 240V unit. Chances are there is something amiss in your circuitry, but if all of your electrical hookup is good, then contact Grizzly Tech Support, and discuss the issue with them. They may swap out for a new headstock or complete new unit. They’ll get it right for you.
Yes, it has a GFCI breaker. My electrician was required to install it per the inspector. If code requires one, what is the fix?
Right now, I am, waiting till early next week for the electrician to add a new outlet that will accept the lathe plug without an extension cord. I am not sure how to get around the GFCI requirement in my area. I am hoping that the electrician can help. I discovered a new "design flaw". I changed the belt pulley setup a couple of times. On one occasion, I did not get it seated well and it can loose when I turned the lathe on. The loose belt struck the rpm sensor circuit board and broke it. the replacement is only sold with the sensor + display circuit board so I am having to buy both. This is not a great design choice on Grizzly's part since a belt slip or break can happen in any lathe. Having the circuit board unprotected and within 1.5" of the belt is not a great choice from a reliability standpoint (I am a retired Quality/Reliability Engineer)
Just be aware that GFCI outlets, and inverters do not play well together. I wired my own circuit for my lathe…..and all of them, actually for the entire shop. Many codes assume that you will use water inside a garage, and thus the GFCI requirement. You probably could get by with changing the receptacle if there is no water inside the garage/basement etc. Not knowing what your setup is, I hesitate to make any recommendations, and safety is always the first and most important consideration, but common sense and good judgment may also take into account the possibilities that a space will only be used in a safe manor, and the assumptions some make about average Joe doing the most unsafe things are in some cases erronius. And of course, if one were to sell a property, then the outlet could always be returned to a GFCI receptacle.
If anyone is still following ... my electrician will hardwire the lathe with a cutoff switch. Then we can use a non gfci breaker and I can turn! A few more days!
I am now up and running! Excited to start turning. Interesting new problem to solve. I can rotate the headstock with a bowl I plan to finish the interior of (started before this lathe arrived). But the tool rest cannot reach inside bowl! Did not see that coming. I have ordered an extra tool rest base from Grizzly ($31) which I will drill out to 1". Also ordered a Rikon 70-960 tool rest extension (with 1 inch post, $50) from Lee Valley to add 7 1/2 inches of reach, allowing the tool rest to reach into the bowl. This will also allow me to use a 1 inch to 5/8 adapter so that I can use my old bowl rests. Will not help with larger bowls, but will allow headstock rotation which was one of the main reasons I bought this lathe. Want to save my back from leaning over the bed.
Good you can start turning. They have kept that model with a metric tool rest post still? What will you do, switch your internals from your old base when you want to use the new one or why not just drill out the one you have? (I'm probably missing something because I've never really messed with a turnable headstock before. Mine slides to the other end but I've never done that either)
