This design allows Cetus 3D printer to sit safe on top of enclosure, and in turn keep foot print small.Īt the time of testing, his heated bed took almost 4 minutes to reach 70C, at a 14C temperature, which is great as compared to the heated bed offered with the printer, that reaches max. Using a dividing wall, he separates low voltage components from high voltage mains and powers off temperature controller at 24V. To print the enclosure on Cetus, Richard puts together in F360. This positions the temperature controller, power supply, and MOSFET board all together. Thermocouple and wires are attached using a capton tape and finally the heated bed is remounted. A simple voltage divider is used to drop 24V down to 12V, the required temperature to turn on the MOSFET board. He then connects the MOSFET board to power supply and operates it using relay output of a temperature controller.

And a bi-metal switch is placed with its input, for the heated bed to stay in safe temperature range even with full power. Resistors are wired up in 4S-2P configurations to ensure current draw from power supply is almost 4.2A for a 100W output. Thermal adhesive can be used for the purpose too. He starts by attaching the power resistors with the two part epoxy. The switching MOSFET and power supply are more than what is needed for application but are used in the project because they were readily available with him.

#Cetus3d slicer upgrade
He wanted to upgrade his 3D printer, so he took some inspiration from a Youtube video of Marco Reps, and rolled up a powerful heated bed. Richard, the initiator of the project is into Magnetic Materials Engineering, and has a great deal of interest in everything related to CNC (Computerized Numerical Control) . Additionally, the heated bed would provide extra power supply to the printer so that overload can be avoided and would give over-temperature protection beyond the usual monitoring. Temperature plays an important role in the printing process too hot or too cold temperature can lead to a mess. This DIY heated bed is designed to monitor and set up the print bed temperature. It assists in improving the print quality drastically by maintaining ideal conditions for the printer to function.
Meaning no fine details necessary and no sharp corners.Heated bed is an added module to 3D printer, that ensures a controlled printing process. I only use it sometimes, for parts that I desinged specifically with this profile in mind. Here's also a link to my current three main printing profiles for Slic3 r/PrusaSlicer (slow/normal/fast) The fast profile will produce quite some ghosting. There, I have also posted my start/end gcode with explanation (It is important you understand what the gcode does!) Here's the link:
#Cetus3d slicer software
I recently made a blog post about the general software setup when getting start with TinyFab (Repetier Host + PrusaSlicer). To get better quality I recommend decreasing the acceleration in the smoothieware configuration from 3000mm/s² to 2500mm/s².Ī bit more interesting is the start/end gcode with nozzle priming. That's assuming your starting with something easy like PLA/0.4mm Nozzle. I currently mainly use Prusa Slicer 2.0 and for a first print you can really just use the default settings and you'll be fine.
