12:48 PM rue_bed: Who is using what for motor drivers then eh?
01:03 PM mumptai: mosfets
01:05 PM mumptai: n+n with integrated half-bridge, n+n with discrete driver, n+p with discrete driver and some fully integrated full-bridges. next "experiment" will be a ifx007
01:06 PM mumptai: also, please state the circumstances for the desired solution
01:09 PM mumptai: also also, l293 and l298 are not really relevant anymore
01:55 PM mrdata_ is now known as mrdata
02:18 PM rue_ is now known as rue_mohr
03:41 PM rue_shop1: hmm
03:41 PM rue_shop1: I'm building a cnc machine, I need 20A @ 25V and want it for less than 8w power loss
03:42 PM -!- #robotics mode set to +o by tolkien.freenode.net
04:23 PM mumptai: 20A RMS?
04:23 PM mumptai: less 8W?
04:24 PM mumptai: Rds,on ~ 5mOhm and an integrated half-bridge driver should do
04:26 PM mumptai: maybe some pedelec drivers could be abused for this too
06:19 PM rue_mohr: can you link me one of these integrated everyone keeps mentioning?
07:29 PM armyofevilrobots: @rue_more ; question. Do you want my old 3D printer (with all components)? It has some LM20UU bearings and rods, as well as the standard old-school 8mm rods and direct drive extruder.
07:29 PM armyofevilrobots: It "works", but it needed some TLC and I just went and bought an Ender3 to save on time.
07:57 PM rue_mohr: hi
07:58 PM rue_mohr: armyofevilrobots, I dont really even have room for my 5th printer, hmmm
07:58 PM rue_mohr: armyofevilrobots, did you get the delta going?
