A5984 AFAIK. I can double check when I get the board out.
I have tried every combination of wires. There is only one combination which electrically looks correct and works at all. I have measured the coils on resistance, so I know exactly which are the two coils. But even if I swap one of them around polarity wise, the motor does not function at all. Seems little odd by itself but that is what happens.
If you look at the video carefully it is running smoothly and then it jumps… Run smoothly then jumps. It does not matter what brand of motor or what I use set the current at or anything.
I don’t know anything about how to control the things like SPI, that is what I was asking in this thread… All I can say is I think the steps are set at 400… Its probably not heard in the video, but I can hear the cycle change as it moves on smooth steps. I just do not see how it can smooth step and jump at the same time. But it does this on various motors and on various ports on smoothie.
I don’t know how you can say this is not a smoothie problem, How do you know something is not faulty on this board ? I’m more than happy to be proven wrong, but I just do not see any way of controlling anything else, hence again asking in this thread.
I have a new board coming tomorrow (bigtree tech) where I will start swapping things about, if I am indeed doing something wrong, then this new board will also malfunction in a similar way. I don’t really see there is any other choices.
