Re: Stepper Motor doesn't do anything...

Hi Burton
I have the same drivers and needed to cut the clk pin to stop it connecting to the pcb but also make a jumper to connect clk to ground.

Stepper Motor doesn't do anything...

I have the MaxESP3 board with TMC5160 drivers and 100:1 geared nema17 motors. I am just trying to test out the functionality before I start work on attaching it to my telescope, and I can confirm through the serial monitor that the board runs, and I have it plugged into a 12 volt power supply. I connected my phone to it through the app over Bluetooth, and I can do a few things so I know that works I think. But, when I try to move it using the app or set a home position, the buzzer starts beeping and the led flashes but no movement in the stepper motor. I tried using a multimeter to see if there was even any voltage coming out to the wires going to the motor while slewing, but I didn't see anything... 

the drivers are Bigtreetech TMC5160 v1.2 and according to the wiki it says I may need to cut the CLK pin. So I tried connecting the driver with jumpers, just not connecting the CLK pin, and still nothing.

I noticed the pinout on the 5160 differs from the writing on the PCB for the stepper wires, so I attached a picture showing that. I used the pcb diagram on EasyEDA in order to find which pin leads where in order to put the stepper wires according to the 5160, so maybe that is the issue?

What are some things I should try doing to figure out what the issue is?

Does it effect anything that I only have one stepper motor connected instead of both?

These values look good to me, as they show that the WEMOS gets power and itself powersup its own 3.3V buck converter...

Do you mean this?
I measure the voltages on the Teensy 8, 9 and 10 pins to GND on the C6 capacitor as well as the GND beside the Teensy 5v VIN pin.

GND to Pin 10 (3.299v)
GND to Pin 9 (3.300v)
GND to Pin 8 (0.1v or 1mV)

When I use the GND near Pin 0 on the Teensy board I get 1-7 mV.

The default SSID came up for only a short while during flashing. I am not sure if it was before the upload or after. I am not seeing it anymore though.

Good idea with the photo...do you have a picture pof both sides of your soldered PCB?

I would like to see measurement taken here (in green) against a GND pin, examples in yellow
C2 - 5v (4.384v)
C2 - 3.3v (3.315v)
C2 - GND (0v)

C6 - 5v (4.384v)
C6 - 3.3v (3.315v)
C6 - GND (0v)

C7 - 5v (4.384v)
C7 - 3.3v (3.315v)
C7 - GND (0v)

All where tested while the modules (Wemos, Teensy, Stepper Driver) were plugged in.

I may be wrong, but if you still see the default "ESPxxxx" SSID after flashing, it means that flash didn't work, you should not see default ESPxxxx SSID anymore.

I also happen to have dismounted and remounted the original EQ6. I do have a couple of replacement worms in brass, should you want one (or 2).

I was measuring 5v to GND pins on these:

It appears the ESP wifi board is working. I would check the solder connections for RX/TX pins on the Wemos, the Teensy, and the pcb. You can check with a continuity meter or just examine them closely with a magnifier/bright light and then touch up any questionable connections with a soldering iron.

Also, you might double check that you have RX/TX to the correct pins, normally they are swapped between the Wemos and the pcb/Teensy, e.g. ESP RX-> Teensy TX and ESP TX -> Teensy RX.

You can swap these if you are unsure, it won't damage anything, but if they are now swapped, the 2 devices will never communicate.
-Mike
How do I swap the pins?
Although I am able to measure continuity (without and with the modules) between these pins.

Hi Khalid, yes im doing that, but it still does not recognize the board after flashing it, BTW im using Arduino 1.8.13 on a win 10, the board is new, this is the fisrt time i touch it... i tried even with 3 different cables, im able to flash but no to see it on com port after i take out the boot jumper

 The resolution is too bad to read the red-on-black text of the IDE output so I can't tell... are you absolutely sure you changed the upload address in the batch file and that the base upload address was 0x8010000?

Yes i use them as depicted in the following picture

Did you use the following options when flashing?

  • U(S)ART Support -> Enabled (generic 'Serial')
  • USB Support (if available) -> CDC (generic 'Serial' supercede U(S)ART)
  • USB Speed (if available) -> Low/Full Speed

Without these, USB is not configured right.

Hi guys,


any advice or fix regarding this issue?

i have fysect s6 v2.0, im able to upload onstep without issues


But then when i took off the jumper and conect the board again to use it, nothing happens, it does not show in the device manager, i tried 3 different computers, and different usb ports, does anyone know what is happening?
