When I issue two successive commands of the form
enc_tgt(1, 1, 20) fwd() enc_tgt(1, 1, 40) bwd()
it looks like only the last one gets executed. How do I make it execute the commands so that it goes forward by 20 steps and then goes back by 40 steps? Do I have to make it go to sleep after the fwd()? If so how do I figure out how long to sleep? Or does it need to be done some other way? Do I need to check the status? Thanks!!!
