Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Fabrication and assembly of table
Preliminary designs are finished
Accomplishments from Previous Week
Presentation
First Draft Report
Wash trough built and tested
X-direction belt drive component complete
y-direction lead screw component complete
Illustrator --> .dxf --> .nc works
wiring diagrams drawn up
Control system redesign: use of post processor than changing LinuxCNC source code.
learned the g-code tool change and homing codes that we need to utilize in our project
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Fabricate new carriage (Kent/Jay)
Mount all components to the table
Assemble materials portion (brush stand, ink pots, wash trough)
Wire motors
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Confirmation that overheating is not an issue for servo motors
Given go ahead with new carriage design
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
New carriage was designed based on previous meeting and brush handles will be reduced in weight as well as refinished to accommodate new holding technique.
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Overheating servo motors may require a cooling system or upgraded
Risks and Areas of Concern
finding and coding a post processor
Smaller servo motors supplied by sponsor will supply sufficient torque
Small and large servo motors will be compatible
Rack and Pinion (should we do teflon on teflon? or linear slider?)
Resources or Information Required but not Available
We need to know if we will be able to use the same motors with the Linux machine system. They may require a minimum voltage that is higher than the motors used in the original drawing table.
Ink pot has not been set up due to lag time on delivery, however it is not essential for initial tests.
Schedule
Complete table with x and y components in order to attach new carriage and test all motors
Research post processing program to change our g-code for interrupts for ink pots and different brushe
Update Gantt chart.
Budget (list amount spent and amount remaining)
$692.62 = duplicate table w/o motors, gears, and timing belts
$384 = motor kit
(3) 425 oz-in stepping motors, NEMA 23
