Deciding The Machine

So deciding the Machine was one of the most difficult task for this week. Everyone had their own ideas to make the machines. Someone wnated to make cnc someone wanted a mahchine that make pots.
After a heck lot of discussions we came to a conclusion that we'll be makin 3 machines.
So the machines we decide was -


Then It was the time as the group to decide the tasks to be done and divide the tasks acccordingly-

As a team we decided like what we need for this group project and segregated each task within the group. First we agreed that we need to do Rapid prototyping to understand it better what actually is needed.
Number 1 priority for the task we agreed amoung ourselves was to do Rapid prototyping and try out following options before we decide the segregation of work.
Since we were dealing with a lot of machines in a limited time we decided to protype things at erly satge and finalize while working on them simultaneoulsy, we were planning to develop machines even after it too therefore trying as many options and exploring each other skills on avery diffrent note was awesome experience.
So we planned accordingly
  • Hector's was on the bit costlier side in terms of material procurement that were it the part of standard Fab Inventory, we focussed on the development of the mechanical structure for the spiral.
  • Parallally using the CNC Available at Lab and MDF boards we planned to make the structure for MTM Snap
  • Since all the elctronic requirement was operating the stepper motors, which was compulsary for everyon to operate rest tasks were divided.
  • And parallally the working on the XY Plotter with Jay Sir's design

The MTM Snap

For the reference we followedNadia's Page.
All the files are given here-

As we were unable to get response in time we decided to go ahead and design the files from scratch for design. It was simple enough so we faced no issues. Please refer group page for more details.

Then there were no coupling available in the local market and the stepper motor we had was not of the exact dimension like the standard one so the coupling dimensions were not matching, so we 3D printed the stepper motor couplings.


The Fusion Files-


We had a Delta 3D printer of some old project which was not under use so I decided to take out the parts from it and use it for mTM Snap Machine.

Things I got Just gotta Learn In a Disassembly of Properly Assembled Machine-

Assembling of The Machine



The Final Outcome

Working On Hector

This was the individual task given in group meeting to work for the hector for the first spiral, i.e planning to get the machine ready and working later for the automation
All the designs for the hector was taken from Jakes Page The inventory was not standard fab inventory, Ashish Sir decided to invest and make hector, and most of the aluminium milling was outsourced because our router capability was till wood.
I gotta see some new machines and learn't a lil about G CODEs and most of those NOO, GOO1 were above my head.
However the milling process was awesome they used delrin as the sacrificial material.

For assembly and joining the aluminium parts plastic was used which was milled on the Lab's CNC Router. For toolpath generation Aspire was used. The rack and pinions were made using the it. Even for drilling we used the cnc because one night when after drilling some points were off for inserting nut and bolts, the manauld drilling on a material like plastic was erronous and there was no vice to fixture it and use the Lathe so we shifted to cnc router and put some drill bits for the task.
It was a crazy experience because like even for a 5mm drill to be exact on the same point we were making the machine to do it, it was actually the Machine making Machine moment
The outcome of some sleepless nights were enchantingly awsome the assembly was ready.

The XY Plotter

Most of the work of the DIY Potter Assembly was Done by Jay Sir You can visit his Page for the Plotter Documentation for the week.
