Direct Drive Upgrade
This LGX™ based upgrade kit is a easy to install replacement of the stock direct drive extruder. It requires the accessories included in the LGX™ Accessories For Sidewinder X1 and Copperhead™ package. This Upgrade Kit also includes the Copperhead hotend, the 24v 25mm fan, and a Bondtech Coated Brass nozzle.
Easy To Install
- Split the stepper motor from the extruder to install it on your Artillery Sidewinder X1.
- Place the mounting plate in between them.
- The extruder is installed facing right, using the included Direct Drive Interface Plug to attach the hotend.
- Set the e-steps value to 400 using g-code.
Leading Grip Power
The LGX™ is the Bondtech extruder with the highest filament grip due to its new large drive wheels that put more teeth engaging the filament.
Start using our newest extruder with our new Dual Drive Technology based on larger drive gears. This is only one of the 7 new features Bondtech implemented on an extruder.
7 new features on a Bondtech eXtruder:
- Larger drive wheels, for increased filament grip;
- Filament pre-tension lever, for repeated results;
- Multi-function interface socket, for tool or application quick swap;
- Drive wheels’ maintenance windows, for easy cleaning;
- Compact, light & symmetric design, for increased performance and compatibility;
- Multiple mounting hole patterns, for easy and flexible setup;
- A small step for a greener Future, craft boxes without bleaching & no coating.

LDO Stepper Motor for Bondtech LGX™
- PH-06AWJ connector
- 2 phases
- DC 5.5 V
- Max 1.0A/phase
To use the LGX, run the stepper motor with currents between ~0.45 and ~0.65A:
Be vigilant regarding the stepper motor surface temperature.
Keep it cool enough to touch. Lower Vref otherwise.
- Class B motor, rated up to 130°C
- Max recommended environment : 70°C
- Max temperature at this environment temperature can go up to 130°C on account of the self heating.
How to change the Current using Vref
It is very hard to read the current being fed to stepper motors. To determine that current we rely on the Vref value. The Vref value is a voltage reference measured in VDC that can be read using a multimeter. It helps us setting the current output of the stepper motor driver.
Different 3D printer mainboards use different stepper motor drivers. Each type of stepper motor drivers has its own formula to calculate the required Vref to get a specific current. Here are some examples:
- TMC stepper drivers.
The formula for these drivers is Vref = ( I * 2.5 ) / Imax
Where I is the target current value measured in A; and Imax is 1.77 on regular mode and 1.2 on SilentStepSticks mode.
- Pololu A4998.
The formula for these drivers is Vref = I * 8 * R
Where I is the target current value measured in A; and R is the Sense Resistor value, that depends on what board are you using. Melzis use 0.1,the Creality Silent boards use 0.15, ...
