Metal Delta KS Campaign Update #10: Contingency November 08 2016, 6 Comments
On the parts:
Haydn's Arms are slowly being shipped in. We currently have 10 sets, and another 10 more coming this week.
GeckoTek wasn't able to ship out the goods last week, bu said that the beds will be shipped out this week. Here's a pic of the bed that they had just got from their silk screen supplier, and it looks good!:
Also, the ramps and arduinos came in. It's still boxed and unopened, but will be inspected this week.
In the mean time, knowing that the samples from the sheet metal factory had a high percentage of defects, we decided to have a contingency on the large sheet metal parts in the event that the sheet metal factory is not able to produce the bend precision that we need. we might resort to a slight redesign of the printer, which will only involve parts that have crucial bend accuracy and precision. It will still be all metal, but the tripod pieces on the top and bottom of the printer will be replaced with CNC'd aluminum, and a few extra extrusion pieces.
The upside is that 1) it will be more rigid, 2) it will be more precise 3) it can be fine tune adjusted to guarantee squareness. 4) it will be manufactured quickly
The downside is that 1) it will be a little more difficult to put together (since the number of parts will increase.) and 2) it will cost more to make (but that's more our issue because we will have to absorb the cost).
Anyway, here are some pics (excuse the mess):
From the pictures, you guys probably already have an idea of how it will be put together. Anyway, once it was put together, we noticed that it was slightly more rigid that the original metal delta design (on the right). The 20mm extrusions and the 8mm thick circular bracket is more rigid than the 3mm bent sheet metal.
Ok so that's it for now, please tell us what you think about the contingency. Your input is very important.
Thanks again Everyone!
