Building a Mendel RepRap 3d printer started in late January. The specific "flavor" we're assembling is a laser-cut Techzone Remix fitted with 3rd Generation electronics and a Thermocouple/OneWire heat sensor. This post is meant to be a progress report and the start of a documentation process for future references.
Here's how it look as of now :
"what's done"
You can probably see on these picture that :
- The frame and platform is fully assembled
- Electronics are installed and mounted
- *All* wiring is done (some is working but will be redone more cleanly)
What you can't see :
- All axis are working
- Sensors are working (IR optosensors and heat sensor)
- Heating element (nichrome wire) is working
- USB>>TTL connection is working and we can interface fully with the motherboard
- "Stock" host firmware (RepRap FiveD GCode Interpreter version 20100806 ) is loaded on the motherboard
- Modified FiveD firmware (on the RepRap forum) is loaded on the extruder controller board
"what's not"
- Assembly of a new extruder (the laser cut gears were too sticky and nichrome need to be rewire). The new design is a Wade Extruder and only the tip need to be assembled now :
- The Z axis drive bars (threaded) stand free in the air : that cause a lot of noise when the extruder carrier go up. We will need to make some kind of crutches to hold it still :
- The bed now stand on bolts (for spacing), we need to put springs instead. Doing so will enable us to precisely level the platform to make sur that our X & Y axis are parallel to the prinmting bed :
