Step 4 (mounting the Z motors):
- 2 stepper motors (1 with long cable)
- 2 printed motor mounts (see photo)
- 8 black bolts (10mm long)
- 8 flat washers (the small ones)
- 2 foam motor insulators
The only trick in this step is to be careful about the orientation of the stepper motors. You want your stepper motors mounted so that the cables coming out the side are pointing the right way:
Note: the orientation of the motor with the long cable is different from the other.
Update: Its easier if you also attach the hose clamp and Z-rod brackets from Steps 14 & 16 now.
Step 5 (frame pt2):
- assembled frame
- 2 long threaded rods (488mm)
- 1 motor assembly (short cable)
- 10 nuts
- 12 washers
Slide the two rods through ones side of the frame, and before you get to the other, add a washer, 2 nuts, and then another washer:
Then keep sliding the rod through the other side until it sticks out 72mm on the left. Add a washer and nut and tighten them down squeezing the acrylic in-between. Then add another washer, the motor assembly, and a washer and nut and tighten again:
Finally, measure the distance between the top and bottom of the side walls and make sure they are the same. You want your walls to be parallel!
Once everything is squared up, tighten down the nuts on the right hand side.
Step 6 (frame pt3):
- assembled frame
- 6 nuts
- 8 washers
- 1 motor assembly (long cable)
- 1 long threaded rod (488mm)
In this step you attach the right side motor assembly just like the left. Then slide the last long threaded rod through the bottom center hole, attaching the washer and nuts like before:
Again, you want the lower rod sticking out roughly 72mm on each end. Tighten up the nuts and your done. NOTE: It looks like the design may have changed from the vision photos. I think the bottom rod may need a bearing in the center as well. I’ll update this page once I know for sure.
Thats it for today, I now need to go take care of other things..
