[Emc-users] Spindle Motors

Is something like this equivalent to a single phase 220VAC 2HP motor? https://www.ebay.ca/itm/122137567723 Just thinking of how I'll add variable speed to my mill. Would it even need a reduction set of pulleys or is 1:1 adequate? If the bearings can handle it a belt ratio of 1:2 to get 6000

Re: [Emc-users] rotary tables, was Home switches.

I was one of the early assemblers of the kits that Andy sent out. Since I'm using step/dir for it there were some firmware bug updates happening and one really great upgrade that makes it easier in the long run to update firmware on both boards. The STMBL is not targeted with step/dir as the

Re: [Emc-users] rotary tables, was Home switches.

For a nicely done rotary table/stepper configuration see http://www.mandalaroseworks.com/product/stepper_relocation The Phase-II rotary table (6-inch) is not bad quality and was occasionally on sale at Enco. No idea where to get one cheap now. I would love a low-profile tilting table for use

Re: [Emc-users] rotary tables, was Home switches.

Although I have a tiny 4" table with a stepper, I'm also fortunate enough to have a Harmonic Drive like the one Andy has along with the STMBL drive.. When I finally get around to casting the holder it will be tall enough to hold a 10" face plate but no wider than the mill table. I am eventually

Table toward you and to the left is machine home. 4th axis on the right hand side of the table. This is how most machines are. Sent from my iPhone > On May 25, 2018, at 1:26 AM, Marcus Bowman > wrote: > > >> >> And that brings up the third question about

New thread, as I seem to be done getting the 7i90 functional. These are capacitive and seem to have good response, universal and programmable. And cheap and u.s. stock, 15.3 mm is the largest of them I can find, and I don't understand what they say about axial or radial mount . I will call them
