Hey guys, not much done in this update other than some designed parts. I designed 2 parts, one to hold the Arduino mega to one of the 1515 extrusions and two to hold the power supply to the lower part of the frame. Sadly the Mega holder had some miscalculations when it comes to the alignment of the screw holes, so I had to re-drill the holes in order for them to fit properly. After that it went pretty smoothly. I had also a problem with the brackets for the power supply. They were supposed to be fastened to the back of the power supply with M3 screws and everything was all measured and aligned properly but the problem was that for one of the screw holes that lies under the power supply for it to attach to the 1515 extrusion, the countersink got messed up because of the way the part was printed, so the screw did not sink, and it lifted the power supply enough for the back screws to not be aligned. So I ended up just attaching the power supply with some velcro ties and they hold it pretty nicely. I also did a lot of cable management for all the cables to go to the back. I used some velcro ties in order to get everything to move towards the back. I attached some of the components to the X carriage, to test the fit of all the part and they seem to work decently. the only thing that i am concerned about is that some of the part are taking way too much space on the XY carriage. I need to move some of the parts around in order to get to have as much travel space as possible. I will eventually get to do re-designs on the XY to get as much travel as possible.
