ER-20 3D Printer
Eryone 32 bit motherboard
The Eryone ER-20 3d printer use the 32bit chip: STM32F103. The 32 bit advantage:
8-bit controllers slow down the hotend dramatically when calculating curves and arcs.
slicers will compensate for slow and complex calculations by reducing resolution, so as not to introduce overextrusion and zits.
appropriate centripetal/radial acceleration cannot be appropriately calculated, introducing a multitude of issues on curves and small segments, including a “lowest common denominator” default speed of 40mm/s or less on complex perimeters.
Print Quality –
better motion planning on a higher-speed processor can product better quality prints, faster.
Our new motherboard built-in the TMC2209 stepper motor driver. With the function of the stallguard, the TMC2209 support the sensorless homing.
Without the limited switch, less deviation and more stable.
Built-in auto leveling sensor
The ER-20 3d printer built-in the ery sensor. We use the new design for the ER-20, no spring and bed adjust knob.
Becuase of this design, reduced the deviation of the bed leveling. Then the ery sensor can work more stable and the bed level is super easy and give you the perfect first layer.
We choose TMC2209 as stepper motor driver and quite fans but powerful which dramatically decreases the noise and improve the printing quality as well.
The average operational noise is 49dBA, enjoy your coffee aside the 3D printer is not only a dream.
Assembly finished within 10 minutes:
The base and gantry of this 3D printer have been pre-assembled, what you need to do is put those two parts together
and wire a few interfaces.
Power failure resume feature:
Built-in supercapacitor and circuit designing, the mainboard will store the height value of Z-axis when the power off.
When the power system resume, the printer can resume the print.
