Hi, just bought some NEMA 17 and mounting brackets from OMC stepper online. Almost done with the build -- yay! As the title suggest my only worry now is what Nut and Bolt size should I be using to mou

This didn't come from Georges kit although I followed the instructions on the Wiki to use machined headers since it will be placed in the recommended aluminum enclosure. I used machined male and femal

#wemos

They look cold solder joints by virtue of bad lighting and poor flux cleanup with IPA. But they are proper joints. The problem looks like the female sockets are not level with the board causing the D5

#wemos

THANK YOU VERY MUCH ALEX for helping me go through the process of troubleshooting. Nearly 24 hrs... of continued trouble shooting. The problem could be a bad socket. When I press down the Wemos on the

#wemos

Nope. I measure both the solder joint of the female header on the MiniPCB as well as the socket itself of the female header where the male pins of the Wemos connects to. All while plugged in.

#wemos

Yes, I was measuring it at the sockets themselves as well. As mentioned earlier, plugging the Wemos in, out and in again while the power is running on the board seems to work. Only problem now is why?

#wemos

I take it back. I removed the bypass BUT I did the same thing I did before. 1. Plugged the MiniPCB into power. 2.Placed the Wemos while power is still on. 3.No light. 4. Removed the Wemos, while power

#wemos

I just bypassed the D5 diode on the MiniPCB with a wire (no soldering). It didn't light up at first but... when I removed it (while power on the PCB was still flowing) and put it back, IT LIGHTED UP.

#wemos

oh, so you mean the diode on the MiniPCB? I thought you were talking about a diode on the Wemos, give me a moment.

#wemos

Yes. How do I short D5? Do I run a wire from 5v Pin to D5 Pin? I'll report once I short the D5 Pin. The value of 5v Pin agaist the capacitor GND?

#wemos

When I measured the Capacitor GNDs it was with the Wemos and Teensy plugged in. I get the same values. I plugged the board in, removed the Wemos and Teensy. I measured O.L on resistance (which means n

#wemos

The Wemos does not blink when plugged into the PCB with or without the Teensy 4.0 plugged as well.

#wemos

Uploaded it and the Wemos is now blinking at a slow and steady pace. I don't know how to send a video but I counted 10 blinks and measure the time, which is about 18.161 seconds.

#wemos

Thank you again for the continued help on this. The soldering is good based on folks at r/soldering haha but I have a second board that I can make just to rule out bad board/solder work. I do not have

Almost forgot:

#wemos

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

#wemos

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.

I was measuring 5v to GND pins on these:
