you can take some acetone and some filament to make a paste that is thicker and matches the color of your parts (due to being made using the same filament as the part you printed) to bond parts together. You can make it as thick or thin as you like, but I like mine to be about the consistency of a milk shake. From there, you can use a tongue depressor to apply it to the parts to join. This will make a very strong bond and will fill in the lines between the parts. You may be able to see a very faint line when it dries, but some sanding will take it down.
Bhouston,
Thank you but don't bother. I only used rafts because Gael suggest it on his website. I'll add base support in slicr and then import them to my davinci software. I need to get proficient at that process anyway. I think that's my last adventure with rafts.
d.cochran,
Thank you. I've heard of that but had no idea it could be made that thick. Bondo for 3D printers! I have to try that just so I can see how well it works. Learning a lot!
I did use raft when I print the big parts (ABS) of the arm.
I also need to sand the edges to smooth the marks left by the raft piece
All the blue parts are made of PLA and don't need to be sanded and fit nicely.
Acetone is working fine to stick parts together. Just use a small brush and wet the joint without touching the surface.
Once the parts are glued together add acetone inside the arm on the seam.
Suggestion, when you decide to glue the nail part on the fingers, just use 2 small drops of acetone, so if one of the braid line get loose or untie, it will be much easier to have access to it.
This is how I ran the wiring for the finger and wrist servos. I connected all Power and Grounds to the terminal in the picture and then ran all of signal wires and the main power wires back to the EZBv4.
Nice work on your arm!
@ bhouston: tanks
good idea with the power and ground terminal.
I was expecting to fit my HDMI in, but I 'll wait later when I print and assemble the bicep.
Richard R,
I went to order an ssc-32 on lynxmotion and it looks like all they sell is the usb version. Are you using the ssc-32 with the DB9 connector?

This only works with ABS but it works very well.
d.cochran.... good tip, thanks!
