This page will be dedicated to my 3D printer. I found out 3D printers while looking for CNC realizations and electronic stuff on internet. I finally decided to build my printer to make some small usefull parts (fastening parts, casings for electronics,...)
I discovered the delta printer and despite the complexity of mechanics (mechanical slack, mouvement control, ...) I decided to start building the rostock because I like the concept.
Because of lack of time to collect all components séparately or making them by myself, I decided to order a kit on ebay including : electronics (Ramp 1.4, arduino Mega, stepper controlers, control screen...) stepper motors and nozzle)
I also ordered the minimum printed parts to make a Rostock printer, ball bearings, power supply, ...
Here is the result after some improvements (bobbin support, auto bed leveling)
The bigger difficulties I faced to get a good print were linked to the bed leveling and adhesion of the first layer on that bed.
After a few attemp to tune the full printing surface bed level (very sensitive and to be done after each modification or
The more sustainable solution I found to solve the bed leveling issue is the auto bed leveling step before each print. I tried a home made switch without succes. the sensor was supposed to make a continuous contact by its own weight when it doesn't touch the surface. When the head of the sensor hits the surface, it breaks off the contact. That doesn't works because the weight of the sensor is too low to make a sufficient contact. I didn't wanted to add weight because it is recomended to keep the moving head of delta printer as light as possible (to reduce inertia)
