The project started as a 1 meter Cartesian Cube. But for easy transportation around the house, I had to reduce the printer width to 83 cm from 1 meter. Printer details can be found below ; Max tested printing speed : 150mm/s Best results as of now : 75mm/s with 550 acceleration & 0.04 junction Deviation Printer dimensions : Length : 120 cm Width : 83 cm Height : 83 cm Current Print Dimension : 60 × 60 × 50 cm Print Dimension upgradable : 120*83*83 cm Endstops set to : 48x * 38y * 28z cm Firmware : Marlin 2.0.6.1 upgraded to 2.0.8.2 with SKR2 Steps per unit A4988 (100, 100, 2600, 95) DRV8825 (200, 200, 5200, 190) Iinear Advancement K = 0.22 Baud 250000 # printing Material (All metal) [PLA, ABS, Nylon, ASA, TPU etc] # 1.75mm filament # 100k ntc b 3950 Thermistor # 12v 40w heating cartridge # E3D V6 All Metal J-Head Hotend Extruder PID Tuning 195°c Kp : 41.88 Ki : 7.41 Kd : 59.18 185°c Kp : 42.65 Ki : 7.23 Kd : 62.90 # Fat Nema extreme Extrusio...
MELS 3D LABS KINEMATICS THE IDEA FOR MELS 3D LABS CHRONOS, A 4 AXIS 3D PRINTER KINEMATICS, WAS CONCIEVED ON EARLY 2021. DESIGNED IN 10/27/2022 AND DIAGRAMS PUBLISHED ON GITHUB ON 7/16/2023 CHRONOS USES INTERNAL RING GEAR FOR THE ARC AXIS MOVEMENTS OF X AND Y WITH A THETA AXIS FOR A TOOL HEAD. PUBLISHING THE KINEMATICS AS A PROOF OF PRIOR ART SEARCH AND TO PRESERVE THE CREDIT OF THE KINEMATICS.
THE PRINTER CONSISTS OF AXES X Y Z THETA AXIS with a gear mechanism for radial movements.
AS 3D Scanner Kinematics : The biggest advantage of chronos kinematics with a theta axis is that a physical model can be scanned perfectly from all sides and angles. Hence allowing a 3D printer to be a 3D scanner as well with a tool head swap.
What is it?
It is a new 3D printer kinematics that takes a different approach for advanced 3d printing with 4 axes than traditional 3 axiz.
What are the benefits?
• 3 axis printers lack vertical strength, Meanwhile a 4 axes printer can compensate this issue to some extent, strengthening parts. • Time saving upto 30% faster than Core xy in theory. • Enables the printer to be a 3D SCANNER, With the addition of theta axis, the printer can be used as a 3D scanner, with a toolhead swap. • Using ring gears, the application can be of industrial and heavy loads. • 4 Axis CNC compatibility
How many kinematics are there?
So far i managed to find these ; in which Itd make Chronos 18th kinematics.
1.Cartesian Kinematics
2.CoreXY Kinematics
3 CoreXZ Kinematics
4.Delta Kinematics
5.Polar Kinematics
6.SCARA Kinematics
7.Stereolithography (SLA) Kinematics
8.H-Bot Kinematics
9.Double Gantry Kinematics
10.Multiaxis Kinematics
11.Parallel Kinematics
12.Hangprinter Kinematics
13.Tilted Bed Kinematics
14.Conveyor Belt Kinematics
15.Voron Kinematics
16.Kraken Kinematics
17.Rotary Delta Kinematics
18.Modular Kinematics
If we classify the major kinematics, it would be
1.Cartesian Kinematics
2.CoreXY Kinematics
3.Delta Kinematics
4.Polar Kinematics
5.SCARA Kinematics
6.Stereolithography (SLA) Kinematics
Making Chronos 7th Major Kinematics.
