The formula is provided in the driver specification. It is the same formula for the TMC2208, TMC2209 and TMC2225 drivers: The cup size can be calculated using the difference between bust size and band size. Refer to the table below. Bust/band difference in inches On the Creality mainboards, the sense resistors are 150 mOhms. Plugging these numbers into the driver’s formula, we get:

when a stepper motor becomes too hot during printing. A stepper motor is expected to heat up but its temperature should never exceed 80 deg C. If you cannot touch a stepper motor with your hand, the motor current is probably too high and needs to be reduced. The band size is the size of the bra band around the torso. However, band sizes come in different measurements in different countries, in that sizes such as small, medium, and large, equate to different measurements. Refer to the table below for some size measurements, though some variation from the published measurements is possible. Band Size A genuine Creality 42-34 round-shaft stepper motor, as used on several of their printer models, particularly on Z-axes. For the Creality 42-34 motor, the max input current is specified as 0.84 Amps. This corresponds to a V REF of 1.16 volts. For the 42-40 motor, the max input current is specified as 1 Amp which corresponds to a V REF of 1.38 volts. Inverted triangle: inverted triangles have a subtle waist and a proportionally larger upper body. Your bust and shoulders are pretty broad, and the hips are slim.

Our body shape calculator will classify your body into one of the seven most popular types. Naturally, not all women falling into one category are the same.

You can identify which stepper drivers your mainboard uses with the letter on the card reader: Creality 4.2.x Identify motor driver with letter on card reader To access the mainboard, first remove the bottom cover. There is one screw at the top and 3 screws at the bottom of the printer. You can also disconnect the fan for better access. Rectangle: your hips, waist, and bust are about the same size. Your body is well proportioned and athletic in appearance. First measure and record the current reference voltages: Turn the printer on. Connect the negative terminal of the multimeter to the ground. Touch each potentiometer with the screwdriver. Be careful not to touch anything else!

If you have an older Ender 3, you may still have an 8 bits V1 mainboard. In this case, the instructions are not directly applicable to you. Creality V1 8 bits mainboard How to identify the stepper drivers on the Ender 3 The Ender 3 comes with 2 types of stepper motors: 42-34 motors on the X, Y, Z axis and 42-40 motor on the E axis. The 42-34 motor is smaller, lighter, has less torque and requires less current than the 42-40 motor. Stepper motors on Creality Ender 3 printers when replacing a motor with another type, e.g. replacing the extruder motor with a pancake motor to reduce weight: the current should be adjusted to match the specifications of the new motor.

The new Ender 3 Pro and the Ender 3 V2 come with Creality 32 bits silent mainboards, either version 4.2.2 or 4.2.7. Creality V4.2.7 32 bits silent mainboard On Creality mainboards, the stepper motor currents are adjusted by turning 4 potentiometers, one for each motor. Each potentiometer adjusts a reference voltage Vref, which is used by the stepper motor driver to adjust the motor current. How to calculate V REF on Ender 3 Bottom hourglass: this body type has a clearly defined waist like the top hourglass. Your bust is smaller than the hips. Triangle: triangles have a slim upper body and wide hips (typically wider than the shoulders). Their waist is not clearly accentuated.When a stepper motor does not provide enough torque and skips steps. Increasing motor current increases motor torque and may solve the problem
