- 178C heat bed has been validated and perfected. Improvements: shortening insulated nichrome length of heating coil from 12' to 6' to facilitate threading of nichrome through insulation.
- Universal Frame Builder - parametric FreeCAD spreadsheet for designing different frame variations for the 3D Printer Construction Set, with export of DXF files. Exporting nested DXF files.
- Universal Axis Builder - Universal Axis Generator at the 8 mm size for variations of bolt length, belt lengths, and rod lengths; allows multiple carriages. Exports to simplified version of the axis for collaborative design.
- Universal Heatbed Builder - spreadsheet bed generator for varying size, heating coils, and bed support mounting. Multiple coils for energy saving can be applied.
- Universal Controller Builder - Universal Controller of different sizes for different size frames, and for varying the number of components such as relays, analog controllers, and other components of choice.
- 3D Printer Product Strategy
- This is Distributive Enterprise Release Candidate.
- Rationale - go to 120V heat bed to reduce power supply size.
- Don't include TMC2130 initially as that will take time to optimize, even though it gets rid of the end stops. Use TMC2208 now.
- Include clean wiring
- Include 3D printed corners
- Building new heated bed allows for a high performance printer
- With 3D Printed control panel, electronics become simpler for builds
- Silent operation is a good upgrade
- 0.26 diameter hole through frame (6.6 mm) and through Y mount to frame

Control Panel Build
Current heatbed uses 16 ga steel plate, and the print surface is 1/8" steel plate with PEI surface on top cut to size, attached with 3M double-sided adhesive. The max continuous temperature of this heatbed is 178C, and it heats up faster than the extruder. It overshoots temperature when cycling to set point, which still works but can be tuned. Standard print bed setting was 80C. When attaching the thermistor, insulate it from the nichrome heater so it reflects more the temperature of the print surface, not the heater element.

Quality Control, Troubleshooting, and Repair
So now you have built your machine and controller. Now here is how to make it work as expected, going through an exhaustive list of potential issues, prior to cleaning up all the wiring.
Suggested Bulk Procedure
- Test that power lights on all power supplies
- For faulty power supply, connect to the back terminals?
- Wires for the power supply to RAMPS - one line for 12V, 2 lines for 24V. Prevents wiring mistakes.
- Use ferrules on wires, and only one wire per clamb-down terminal. If multiple, join them elsewhere.
- Clear wiring labels
- Extruder fan - 1 line on red/black wire
- Print cooling fan - 2 lines on red/black wire - or use different color wire
- Extruder heater block- should be high t wire, different than others.
- Power supply power cable issues
Cleaning Up the Wiring
The final wire routing should look like this on the control panel:
- All wires tight and out of the way
- Any wire that is too long is pulled behind the Control panel or near the cable chain and zip tied neatly to other wires or fixing points.
- All wiring is kept accessible for repairs and upgrades
- A shield is placed in front of the power supply to prevent any shocks.
- Wires from stepper motors are hidden along the corners of the frame
- Stepper motor wires are oriented so that the closest path to the control panel results.
