Hi there, first post on this forum - should have got here sooner!! I just wanted to get some general feedback from anyone with experience, I'm working on an automated telescope project that uses a pair of 4 wire bipolar stepper motors for azimuth and altitude control, the steppers are driven with an L293D module each and supplied from a 5V 6A supply. I have written a python script that should sequentially increment the steppers with full step / two phase logic. Neurosolutions 6 12 Keygen Mac.

Everything is working pretty well but I have a couple of motor issues I really need to iron out before I progress - I expect they are all related to some extent: Big problem first - the motors can sometimes become unresponsive and worse, seem to loose all torque as if I sent 0 0 0 0 to the coils - but the only condition I send 0 0 0 0 is during start up and shut down of the script - this problem only happens when the motors being incremented (never when still). Little problem - the motors don't seem to increment equally, a bit like step, step, jump, step etc At the moment, both the motors and the L293D modules get very hot, the modules have a chunky (stock) heatsink on them - I am wondering if the L293Ds are actually being pushed a bit to hard and have some kind of thermal shutdown? But if so, why wouldn't they shutdown when the telescope is just being held in a position of strain? Otherwise I guess there is a possibility that wiring is getting moved a bit much and actually loosing connection, but I have been monitoring this quite carefully.
