A simple hardware solution is simply to strap the necessary input pins together: 1-5, 2-6, 3-7, 4-8<BR/><BR/>Slight fly in the ointment: Last night my motors refused to turn over. Dunno why yet, but the comms is still working. Will investigate.<BR/><BR/>Vik :v)Vik Olliverhttp://www.blogger.com/profile/08344580890636084746noreply@blogger.comtag:blogger.com,1999:blog-12223283.post-1144720245368928822006-04-11T02:50:45.366+01:002006-04-11T02:50:45.366+01:00YES!

Simon just updated the Bipolar stepper motor driver to control multiple motors of on axis control. Couldn't we Control two unipolar stepper motors of the ULN2803 darlington driver currently in use on the unipolar driver? Just a question for some of us planing on putting two motors per axis on with unipolar motors. Seams like we have 8 bits to work with. Just dump the same bits into the other four inputs and we could drive two motors.jgeorgehttp://www.blogger.com/profile/08926316751990470623noreply@blogger.com
