درایور استپر موتور MKS LV8729 OC Ultra Quiet Stepper Driver 1.5A
MKS LV۸۷۲۹ توسط شرکت MAKER BASE طراحی و ساخته شده است. که یک درایور استپر موتور بسیار ساکت است و از EN + / - ورودی پشتیبانی میکند.یک برق MKS LV۸۷۲۹، DC ۹ را تامین میکند، و برای موتور پلهای Nema که کمتر از ۱.۵ A جریان دارد، خوب است.
MKS LV۸۷۲۹ با برد های MKS GEN، MKS SBASE و RAMPS بخوبی کار میکند .وبرای ساخت پرینتر سه بعدی، دستگاه حکاکی، CNC و غیره مناسب است.ویژگی بارز این درایور میکرو استپ بالا و تا 128 میکرو استپ است.
Features
1.DC 9-32V,it is better to supply by DC12V or DC24V.
2.Use high speed optocoupler ,not lose step.
3.Use SANYO LV8729,which protects circuit and supports 128 microstep.
4. MAX current:1.5A.
5. Microstep: 16 / 32 / 64 / 128.
6.Bigger heat sink, better cooling.
Notice
1.Please mind the polarity of power ,or else will burn the chip.
2.It is better to set the current below the rated current of motor,
and advise the current less than 1A.For MEGA2560 controller,
advise not over 64 microstep.
3. Switch1,2 are for Microstep, switch3,4,5,are used to current,
and switch6 is input mode.
As follows:
1). Following wiring scheme is Common Cathode input, which put switch6 to ON.
2).Following wiring scheme is Common Cathode input, which put switch6 to NO.6.
3).Following wiring scheme is Common Anode input, which put switch6 to NO.6.
Meanwhile,find and modify into following values in Marlin configuration.h .
#define X_ENABLE_ON 1
#define Y_ENABLE_ON 1
#define Z_ENABLE_ON 1
#define E_ENABLE_ON 1
According to some customers’ feedback, the motor is only in one direction when MKS LV8729-OC works with MKS Robin or MKS SBase. After testing, we found the excessive resistance of the driver’s DIR interface caused the insufficient current. To solve such problem, you only need to reduce the resistance value of the drive or make resistance short-circuit.
Method: Remove the R7 resistance of the PCB, solder it to be short circuit, then it can work normally.
Note: the DIR resistance has been changed into 100R, so all the MKS MKS LV8729-OC on sell now can be used directly.
