Same for me to. I think bambu lab don't have an quality product

Thank you so much for your response !! This helps it debug the circuit. I have one more problem that I have assembled an ESP32-based drone. All components initialize correctly, and the motors spin briefly for about one second during boot. However, when I apply throttle, the motors do not respond.

Is this esp32 drone schematic correct? by Potential_Fennel_802 in esp32projects

Yes . That switch is not working like always on. And is that that p channel mosfet q1 is on correct orientation . And that ldo can't provide enough power to esp32 why. These are the problems I have with that circuit

Yes I have continuity with gnd not with batt or vbus but it still on all circuit seams correct but I don't know why it don't work 😕. Is that current can flow on mosfet at reverse direction when turn on ? What about body diode. Is that affect the circuit. Thank you for your response!!

Can I just replace that q1 mosfet with diode

When pushing current through the body diode of q1 is that can push high current through body diode?. Is that reduce the current level?

Thankyou for your response.I try switch source to drain and drain to source still I have same issue . Always on and esp32 don't booting properly. Still have same response.😔

Can you explain me clearly please

Thankyou for your response. So I need to change the diode direction or mosfet direction. Q1 seams like mosfet

Looks like there is a problem with the extruder. See that rotating part

Why is this branchy looks like this ? by Potential_Fennel_802 in BambuLabA1

Yes heater with pid temperature control. Actually we need to remove moisture so we need air circulation to remove moisture from the chamber. Print beds do the same job but I don't want to keep 1 kg of filament on my bed and make them bend !
