Project Description
I have a DIY 3D printer which I am updating and modifying for about 4 years now. Originally it was a Voron 1.6 model but over the course of time I modeled my own parts and at this point it did depart quite a bit from here. This project is about doing further redesign and improvements in general. There are couple of tasks I can pick from and I will do so depending whether I feel like 3D modelling or digging into software side of things.
Goal for this Hackweek
Choice A: Redesigning printing head (probably XY axis as well) * current one seems to be producing artifacts due to instability * has exposed connectors
- New printing head will have:
- 2 linear rails instead of one
- 2 40mm radial part cooling fans
- Omron TL-Q5MC2 inductive probe
- Dragon hotend
- hotend cooling - probably 30mm fan due to space constraints
Horizontal X might be an interesting concept to try
Choice B: klipper monitoring using grafana/influxDB/telegraf
- research telegraf/influxDB/grafana setup for monitoring
- collect general data from Raspberry Pi controller
- collect printer data from Klipper
Choice C: LCD screen and Raspberry pi case
- Raspberry and LCD are mounted together
- currently there is no case for them, only a frame
- case should have ideally a small fan for better cooling

I ended up working on option A: Redesigning printing head (probably XY axis as well)
New toolhead has all the components I wanted:
- 2x Radial blower part cooling fan
- Dragon hotend
- 30mm hotend cooling fan
- Omron TL-Q5MC2 inductive probeAdditionally I purchased TMC2209 stepper drivers and enabled sensorless homing which allow homing without using endstop switches. I had to as well remodel X-axis joints because previous ones used only one linear rail.
Parts were modeled in Autodesk Fusion 360 and printed on original printer - yes, printer was printing itself!
Disclosure: Models for components like fans, screws, hotend... etc were not mine, but taken from grabcad library. I designed only body which holds all components together (grey, red and black parts :D)
