Nema 17 + l293dne, problemi con vibrzione

-

ciao tutti
ho un problema con il mio motore passo passo bipolare, uso questo
classe: nema 17
modello: 42byghw804
phase: 2
step angle: 1,8+-5%°/step
voltage: 3,84v
currect: 1,2a/phase
resistance: 3,2+-10% ?/phase
inductance: 5,0+-20% mh/phase
holding torque: 48 n.cm min
detent torque: 2,6 n.cm max
insulation class: b
lead style: awg26 ul1007
rotor torque: 68 g.cm2
shaft diameter: 5mm
shaft lenght: 20mm


e uso il driver l293dne
il problema è usando la libreria stepper o accelstepper, impostando 200 rpm ottengo delle vibrazione e ogni tanto si blocca, rallenta poi riparte non lo perchè?
leggendo alcuni articoli su internet, risulta che bisogna usare un driver di tipo sn754410 o udn2916b per erogare una corrente di massima 1a. ma il mio motore accetta fino 1,2a quindi dovrebbe andare bene anche il l293dne.
qualcuno ha un idea?
perchè anche usando nessuna libreria vibra lo stesso.
grazie in anticipo.

la corrente di fase del tuo more è di 1.2a
mentre da ds l239 ne tra 1a... non la vedo bene la cosa (poi immagino 1a ben dissipato ;) )

Multithumb configuration params not working? - Joomla! Forum - community, help and support

hi, i've installed multithumb 1.1 on joomla 1.011 site , works fine in basic set-up (and jce-editor). except when try tweaking mambot params, things stop working. specifically: if use "only in these categories" setting , fill in categoryname, e.g. "news", pop-ups/thumbnails stop working, categories, including "news". if use "not in these categories" these categories still use pop-ups. if select "use thumbnails" "no" not no thumbnails no pop-ups anymore. so way use multithumb selectively use optioni "apply content {multithumb}", bit cumbersome. there more people having these issues? hi bikey, i having issues bit different - yet same.  saying have way set configuration plug-in.  not know how find cong this.  if can maybe read posting - don't bore process.  jce editor - have not installed - still using default html editor - cant recall name.  why not see config file? anyway - find if use static page , pass com...
