[02:02:05] <mase-tech> Is TB6560 Stepper Motor Driver not working with emc2 ?
[02:02:25] <mase-tech> Is it listed in faq
[02:02:29] <mase-tech> I cannt find it
[02:07:37] <archivist> plenty use them, just do not disconnect the stepper while powered, the chip fails
[02:12:17] <mase-tech> CNC TB6560 4 Axis 3.5A Schrittmotor Stepper Motor Driver Board Controller -> 55 Euro
[02:13:08] <mase-tech> SainSmart 5 Axis Mach3 CNC Breakout Interface Board(Blue) For Stepper Motor Mill -> 15 Euro
[02:14:56] <mase-tech> Secound one can be supplied with 12V - 24V
[02:15:53] <archivist> I use this style http://www.ebay.co.uk/itm/5-Axis-CNC-Breakout-Board-with-Optical-Coupler-For-Stepper-Motor-Driver-MACH3-CF-/272041782661
[02:16:02] <archivist> they work
[02:16:48] <mase-tech> Why is the tb so expensive, when I compare these 2
[02:16:57] <mase-tech> I mean if they do the same work
[02:17:05] <mase-tech> there is no point to buy the TB
[02:17:08] <archivist> tb?
[02:17:25] <mase-tech> TB6560
[02:17:41] <archivist> what are you comparing with
[02:18:01] <mase-tech> The TB 6560 with http://www.ebay.co.uk/itm/5-Axis-CNC-Breakout-Board-with-Optical-Coupler-For-Stepper-Motor-Driver-MACH3-CF-/272041782661
[02:18:35] <archivist> breakout board uses external stepper drivers
[02:19:04] <archivist> tb6560 is only a chip type
[02:19:27] <mase-tech> So I need these friends http://www.ebay.de/itm/Neu-CNC-2M542-Stepper-Motor-Driver-Controller-4-5A-Support-Nema17-23-34-DE-Lager-/221284045722?talgo=origal&tfrom=320985159251&tpos=unknow&ttype=price&ssPageName=STRK:MESE:IT with your posted board
[02:20:16] <archivist> yes or a tb6560 driver / whatever
[02:20:45] <archivist> url for the board you were looking at
[02:22:21] <mase-tech> http://www.ebay.de/itm/CNC-TB6560-3-5A-4-Axis-Stepper-Motor-Driver-Board-Controller-4-Engraving-Machine-/221163271122?_tf=221154255040&talgo=origal&tfrom=320985159251&tpos=unknow&ttype=price&ssPageName=STRK:MESE:IT
[02:24:23] <archivist> breakout is included on that board (opto isolator section)
[02:24:52] <archivist> not all tb5660 boards have it included
[02:29:02] <mase-tech> how u like this bundle
[02:29:03] <mase-tech> http://www.ebay.de/itm/4-Axis-1-2N-Stepper-Motor-3-5A-Driver-TB6560-Nema23-USB-Interface-Board-CNC-Kit-/252299332704?hash=item3abe364c60:g:egEAAOSwFNZWzsU7
[02:29:11] <mase-tech> 144 euro
[02:29:17] <mase-tech> seems cheap
[02:29:31] <mase-tech> nema 23 motors included
[02:32:07] <MrSunshine> hmm i wonder if its a good idea to use a 700 rpm motor for the lathe, as the torque will be alot less than with a 1400rpm motor with greater reduction :/
[02:48:12] <MrSunshine> or am i thinking wrong here? =)
[02:48:18] <MrSunshine> as 1.1kw is always 1.1kw :P
[02:48:30] <archivist> depends on motor :)
[02:49:15] <MrSunshine> archivist: but .. 700 rpm 1.1kw or 1400 rpm 1.1kw that has the same speed at the end of the reduction train ... the torque at that place would have to be the same? =)
[02:50:20] <archivist> power=torque*rpm ish
[02:50:53] <mase-tech> As I am looking for power supply I find that quit expensive
[02:51:05] <mase-tech> 100 bug
[02:51:09] <mase-tech> holy moly
[02:51:23] <mase-tech> I need 8 amps
[02:51:30] <mase-tech> I think
[02:51:34] <Deejay> moin
[02:51:38] <mase-tech> Servus
[02:52:03] <mase-tech> 2 amps for each nema 23
[02:52:21] <mase-tech> 100 bugs for such a supply is ok ?
[02:55:04] <mase-tech> http://www.amazon.de/360w-regulierte-Schaltungs-LED-Power-Supply/dp/B00F19QY8C/ref=sr_1_52?ie=UTF8&qid=1461310121&sr=8-52&keywords=cnc+power+supply this one should do the job ?
[02:55:11] <mase-tech> 39 bugs
