I'll check on her I think, since they aren't allowing visitors, a couple times a day. HIPPA makes that a PITA.

They've not yet got that hard up for spares, OTOH, my legs have been attached to a DM-II for nearly 30 years, so I don't imagine they'll make good spare parts. The right one in particular is a bit rough. ATM I'm up cause its cramping and I've just given it a rub with therawerks. They've also been stented already. That was some of the first 4 or 5 stents they put in, not all were in my heart. It has reduced the edema some, enough to be noticeable. I had started to see if I could find a hub for a printed sprocket with the lathe and a block of alu, but the heat and humidity ran me back into the AC, and when I later made a run to the mailbox, surprise, there were 2 all metal sprockets in it. So now I need to find enough bolts to mount the adapter plate, from nema 34 to nema 23, and the belt should till fit. This is an experiment of sorts, replaceing a very noisy 1600 oz/in motor with a 3 phase 3NM motor that thinks its a step/dir driven servo. I've not used one of these before. It should have enough power and be 50 db quieter. These 3 phasers are 1.2 degree motors, so I'll have to recal the scale. Running on a function generator it goes up to about 2500 revs before it faults and the torque at 1000 is amazing, so I think it will work just fine. But I'll have to splice the motor cable while I'm switching it to 3 wire drive from 4 wire. Apparently the vender didn't src it all from the same place, so the encoder cable is a couple meters longer than the motor cable. No biggie for me, but I hate splicing cables in the middle of a run. I'll put the other of the motor pair w/drivers I got for $250 on this BS-1 if I can cobble up an on-center shaft for idler stuffs, and maybe put gears for the 2nd stage of geardown since theres only about 40mm between the tilt axis central point and the worm shaft. Thats the plan anyway. What I want isn't speed, but enough power to drive it while its cutting a gear, which can load up the worm and make it very hard to turn. I'd bought another qctp as the one of the lathe was falling apart on one side, had it for 2 or 3 months, BOSTAR brand, dirt cheap. And today found there is a diff between 250-1xx toll holders and 250-2xx tool holders. Different width, and slightly diff dovetail angles. As Jackie was fond of saying, what a revolting development that is. The -1xx stuff fits a piston qctp, the -2xx stuff fits a wedge locking qctp. The advertisments doesn't make that distinction. So I'm a wee bit schmardter today. Take care and stay well, TomP. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
