01:09 AM mrdata: Phantom, some servos are geared down a lot
01:18 AM Phantom: servo yes, but not steppers
01:18 AM mrdata: correct
01:18 AM Phantom: I'm surprised that there is none for 3d printer extruder... you know, a 10 times weaker motor with a 10:1 gearbox would be super lightweight
01:18 AM Phantom: backlash for this application would be irrelevant
04:05 AM veverak: nah, you do not want it mcuh either and afaik DC mottors have much less torque than steppers?
04:06 AM veverak: that implies higher than 10:1 ratio which given the forces requires gears from materials that are able to withstand something and the gearbox has to be done properly
04:06 AM veverak: (so it is smooth)
04:06 AM veverak: so you gain a lot more complexity, more strict requirements for quality of parts/anything and gain little less weight?
05:30 AM Jak_o_Shadows: Those hollow shaft ones are interesting
05:30 AM Jak_o_Shadows: the rotary ones
09:31 AM rue_mohr: the cat wants to come in and use the litter box....
09:31 AM rue_mohr: she it out now...
