They move up syncronuosly but one motor doesn't move down after hitting the endstop? Do you run them by one driver? Parallel or serial? Do you feel excessive friction when turning the lead screws by...

Hello to everybody, I have a stepper driver shield (for Arduino UNO) and Arduino Mega2560 :D (And use GRBL for mega2560) I connected only one motor on z-axis for my tests and this is the result....

It seems, the shift registers need some initialization code to configure MS1-MS3 of the drivers? Or are they pulled to GND automatically? Why not use a RAMPS shield with GRBL?

... could be, your drivers draw more current from the +5V of the Arduino, than the voltage regulator can deliver -- so the +5V of the Arduino breaks down and the program stops. If it's working fine...

With the TMC2208 you need to use the UART configuration with a USB-Serial adapter with your computer. Its really nice actually, it lets you change any setting about how the stepper diver functions and...

Hello everyone, i'm strugling in feedrates and aceleration, cause I cant insert more than 5mm/s in xy feedrate and 5mm/s2 in aceleration(more than this value and i get skiping steps), but in z axis i...

Why do you drive the steppers in full step mode? Did you adjust the driver current? Can you move the XY-mechanics easily without binding?

I'm using marlin as firmware, i'm not an expert, but if i use microsteps, they lose their strenght, right?I've told that z axis can handle more feed rate and aceleration, but I did a test with my...

Hi, this is a question that is related to the use of the TMC2208 silentstepstick and similar stepper drivers. When I apply 24v to the VM/ground pins, the driver chip gets fried. This happens...

Maybe you plugged the driver in the wrong way round? Or, if you had to solder the header pin strips on yourself, maybe you soldered them on the wrong side of the board? Hint: on some types of driver,...
