I've been really impressed with RepRap Pro huxley kit. The parts area really clean, and don't need much in the way of reaming of trimming with a knife.
What I've also enjoyed, is that all the pieces for the printer arrived in one go. In building my Sells, I had to wait for each order to arrive. I'm also less concerned that all the various components will match.
There was a slight delay in getting the delivery, since they were waiting on a particular part. However I've got to hand it to them, there communication is great.
Last couple of weekends, and evening have been spent putting things together. I'm tested everything
However I hit a snag with the electronics. Although initially things worked as planned, they went down hill fast.
Having tested things intially, I then remembered to turn the pots to reduce the current to the stepper motors. It seemed that it took a larger number of turns than I thought possible with such a small component. In fact I never got to the a stop point. After a while I stopped and turned the pots 30^ clockwise. I also connected the heated bed.
The second time I turned on, and connected the printer, I had no such luck. Although the printer connected to the host software, and both hot end and heated bed responded. No stepper motor worked at all. I thought I had turned the pots to low. So I executed a home command on one axis, and turned the pot clockwise a number of turns.
I think I may have turned the pots too far, and broken them.
