    I am also using the marlin firmware from David Ramiro which has the 12V mod and that also requires to run it with a lower percentage if I understood that correctly :. EDIT: wow you aligned the labels perfectly. You can use every RS serial adapter with V logic levels e. Wow, thanks a lot. Star 4. Enable or Disable Cookies. After viewing your video, mine does the same thing.

    Now, when fast extrusion or retraction occurs, there's a nasty noise from my extruder motor. Can it be that V is too low for E0? Note that I have the newer/.If we are installing new drivers we must get the direction right, on the back of the drivers we will see some writings right next to each pin.

    heavenmanga.online › Basics.Rsense — The A boards are based on the Pololu board and therefore use a resense value of 0.

    Follow this guide and become your own Vref calculator! Contents. What Is Vref? What You'll Need; A Drivers; TMC &.So I messed around with printing some dampning pads using flexible filament and quieted things down even more.

    I've got a Mega X and set the Vref for the XYZ motors to V and for the extruder. These values were recommended in the Anycubic.I went back to stock for now for the extruder.

    The best way to set the motor current is by measuring the voltage on the Vref pin (0 V) and adjusting the voltage with the potentiometer. The maximum.I feel like there is a vibration component to the noise as well.

    Ender 3 VREF TMC / TMC does not give the expected results, in fact, it could happen that the extruder still loses a few steps.Much torque means a lot of electric current.

    forum? The extruder motor, however, requires a lot of torque to press the filament When measuring Vref on the TMC, you need to measure the.I believe a vref of 0.

    I was all very well aware, however, I noticed that extruder sometimes suspends I believe a vref of volts on a would be amps.I had also turned down the retraction speed a while ago and that helped.

    This can be anything from under extrusion, over extrusion, parts that don't fit properly, clogged nozzles, etc. TMC VREF Location.PS: you can connect both the Z axis "Z and E1 are used for the z axis" to the same pin.

    Can it actually be that Vref does not actually matter if within a certain interval?

    However, when I put in the Noctua and turbofan see picture below they don't turn at all before you ask, they work fine when hooked directly to and external 12V supply.

    Note however that there are a few remixes out there now, that might be better.

    Try running the filament removal, that runs it in reverse until the filament is completely out of the tube.

    Vref measures Gnd and the voltage at the middle of the potentiometer.

    I think calibrating the esteps might also be a good idea after replacing the drivers.

    So it does not make sense to install this extension when using the TMC

    So the motor has to spin extra fast to get similar retraction speed as a stock extruder.

    Power should be connected when measuring voltage, do not just connect USB power supply.

    I've changed the extruder fan to a A4x10 with no issues.
