Enlarged Rostock

thingiverse

Rewrite of text: This is a modified, larger version of Johann's Rostock 3D printer with an increased build area of 400x400x500mm. It features motor-end parts, idler end parts V1.2, carriage parts V1.2 and two bed parts from Thingiverse. The printer is being assembled at the Artilect Fablab in Toulouse, France and a blog-like story of its build and setup is detailed in the text. In late August, the discoverer of one of the idler end designs updated it for strength and better installation of end stops. A magnetic bearing improvement was found by Antonio Bencini for the enlarged Rostock. The printer's platform was forgotten during a holiday break, but was later corrected with unchanged original Rostock STL files. Various improvements were demonstrated at a presentation in French, and calibration adjustments were made following Triffid Hunter's and Tantillus' calibration guides. The printer was shown at the Artilect Fablab Toulouse and modifications included adding cable tensioners for increased speed, insulating the hot end for efficient cooling, and tightening belt connections for improved accuracy. The first perfect print was achieved using blue PLA with a 0.2mm layer thickness. The Rostock experienced thermal issues, but these were addressed by slightly tightening belts and printing larger objects. A post-mortem analysis of the J-Head thermistor led to its restoration, and calibration was properly adjusted for temperature measurements. An attempt at printing Lucy the Cat resulted in some failure before achieving a successful print resembling the STL model. The next steps included fighting play for precise alignment, addressing extruder issues, and exploring an interchangeable system for both boost and bowden extruder setups. The first print was accomplished after resolving several issues, including replacing the 644 Atmega chip with a 1284 for Repetier firmware compatibility. Issues with heated bed temperature and extruder feed were resolved, but play appeared in joints due to transportation. A first print of a cube was achieved using Repetier firmware, and calibration adjustments continued. The hot end assembly was attached to the extruder, and Marlin configuration files were downloaded for further testing. Temperature measurement issues were resolved, but repetier firmware setup required fine-tuning for delta mode operation. The printer's end stops were installed, and calibration began with some initial drawing experiments. Issues with homing movements were addressed, and pulleys were replaced to ensure proper tooth count. Repetier firmware was tested, but memory usage issues arose and needed to be adjusted. The platform and diagonal rods were fitted, and the printer underwent continuous setup and calibration. The BOM includes various purchased parts such as motor shafts, linear bearings, Gen 7 V1.4.1 board, NEMA 17 motors, belts with pulleys, hot end J-Head MK5B, and carbon arrow diagonal rods. The total cost of these parts was approximately €625. Optimizations could have been made to reduce costs while maintaining rapid availability of components.
