Information

The BreepBroop in it's current state

General

The BreepBroop (nickname) is a standard RepRap Mendel. It's the original design, and was printed during the main build rush after the Mendel came out. Chorca printed the parts on Mack's MakerBot over a period of about a month. It is all ABS aside from the frame vertexes which were purchased from the RepRap Forums, from Joshua Updyke in particular. This style of Mendel is rarely made anymore due to it's complexity. The much simpler Prusa Mendel is more commonly built, due to the large reduction of printed parts and hardware, and the simpler pulley and bearing systems used. Digitalman2112's RepRap is a Prusa.

Electronics

The BreepBroop originally used a Techzone Gen3 electronics set, which needed a good amount of touch-up and had some issues. Chorca replaced this.

Mechanical

Most mechanical functions of the BreepBroop are according to the original build specifications. Few modifications have been made:

Software

Chorca is currently using the following:

Print Status

The printer is not printing. After a total rebuild of the hot end and reassembly, we are still having major issues. It was able to successfully print a Wade's extruder gear, however, the PLA was burning and oozing out of the top of the nozzle slightly. The X axis is cracked near the belt clamp area and binding badly. The Y axis also has a lot of wobble due to the weight of the copper plate. There are no endstops so homing is a major issue. The extruder constantly strips because of the shallow hobbing and due to the fact that the thermocouples are difficult to use in getting an accurate temperature reading, it is hard to figure out what the temperature currently is.

Current Work

Electronics

The electronics system is a mess, and is very hard to operate. There have been great strides in ease of use, mainly with the RAMPS platform. This integrates all components onto one shield for the Arduino MEGA, reducing footprint and making everything a lot easier to run. The following are current plans for work:

Mechanical

The hotend needs to be replaced and the Wade's upgraded. The X axis needs to be redone, preferably with a Prusa-style carriage to reduce weight and complexity. The following are current plans for work:
