• creating x1.25 model

  Abd-el-rhman • 01/10/2016 at 15:10 • 0 comments

  since there were a lot of problems in dealing with the x0.8 derived version of the original design in inventor, I had to think of another solution.

  this solution is to create the NEma17 hole dimensions multiplied by the factor 1.25 so that when a 0.8 model is derived the dimension return back to the actual Nema dimensions.

  the was another problem with the gears offset due to the change in the shaft hole.

  I dealt with this problem by changing the screw joint locations by shifting the hole extrusion to the right by 0.224mm and upwards by 3.218mm.

  I am to check the design and create assembly file.

  I hold up the 3D print order till I am sure about the design.

  the new dimensions and the assymply file of the new x1.25 solution will be up soon.

  Today I started to:

  - learn file extension types .ipt and .dwg

  - downloaded autocad 2016 to view the robot design and got licensed.

  - couldn't open because I needed inventor to view the parts and assembly files.

  - got with @sai and sat a meeting to discuss our target

  - viewed the forearm design with a360 online viewer and measured the dimensions.

  - ordered the 3D to be printed (will decide tomorrow)

  To do:

  - get inventor, view the design, try to readapt the design.

  - find other 3D printers able to get the original design.

  - order the ball bearings, motors and nuts.

  - keep track of the whole project.

  Today,

  We have installed inventor 2016 to our

  Windows pcs so that we can view the design.

  - we started reading and listening to Tutorials describing the main features of inventor 2016.

  We set the target to reduce the current design to 80% of it's size now.

  -Regarding screws and motors we will maintain them as the original design was too heavy to be powered solely by Nema11 and Nema 17.

  - our next move is to keep learning about inventor and try to reduce the size of the design with maintaining the same size for the motors..

  -another approach is to look for a bigger 3D printer that can print the original design with lighter materials.

  3rd jan (Happy new Year 🎉🎉🎉🎉 Malik

  I have completed the Inventor tutorial and heading towards editing the master design..

  My plan is to edit the base items first and print them.. Then evaluate

  End.

  4th jan

  today I successfully edited the motor extrusion and uploaded the scaled base-segment.ipt file and the base with the Nema17 motor.iam file here.
