RUG/Pennsylvania/State College/Printers/PSU Unit Mondo
On this page you will find the current status of the Unit M Mondo. Our Mendel Unit is a Techzone laser-cut Mondo. So far, we have replaced the extruder (11/8/12) since the Techzone wooden extruder used springs to tension the idler. The new extruder improves this by using two bolts to tighten the idler. Update: (11/29/12) optical endstops were replaced with mechanical endstops and firmware was upgraded. An overhead filament holder was added to keep the filament from tangling on the table. Eventually the plan is to use this large unit with a dual extruder. Much more information can be found at RUG/Pennsylvania/State_College/Dual_Extruder

Build Status
UPDATE 12/12/12
The Mondo is fully operational! It has been a long time coming but everything is working properly. The Mondo has been working for several days now and is producing decent looking prints.
What needs to be done:
1. The print bed might be warped? X-axis may need to be leveled? either way, the Mondo is having trouble making consistent in different parts of its large bed.
2. A large print has yet to be attempted. One of benefits of the Mondo is it can print large objects, wide, long and tall. Attempt a large print to see how the Mondo deals with it.
3. The Y-axis is very shaky. When tall objects are printed, the higher the print gets, the more error there is due to shaking and vibrations. The wooden Y-axis supports should be replaced or reenforced to reduce shaking.
4. As mentioned below, the Mondo is the prime choice to have a duel extruder. The extra vertical space will definitely come in handy. What has been done: Frame assembly, Electronics installation, Replaced Thermistor with Thermocouple, Adjusted Steps/mm, Adjusted BOD rate to in Marlin to 115200, Tuning of Motor steps/mm, Installed new Extruder, Replaced optical endstops with mechanical, installed overhead filament holder.
Mostly up and Working, small adjustments may be needed.
What needs to be done: Fine tuning of Slic3r settings (Mondo Slic3r configuration file is on the new HP computer in the corner). Some motor belt adjustment may be required. Exact bed size to be determined.
