Even more genius!!!! I love the straightforward way you explain things. Repairing furniture so it doesn't go to the dump is just awesome. My recliner is stuck in the lift position and will not retract. Although I've ordered a new motor, I may try this now that I know where the limit switches are located! Do you know where the control boxes for the chair are typically located? The heater/massage junction box? Subbed!
The bulk of the control circuitry is located in the actuator itself. In my actuator, the circuit board with all the extend/retract logic is tucked in next to the motor. I would guess (I don't know for sure) that the actuator outputs of the heater massage junction box would just show up as an extend and retract signal to the actuator control board. It's difficult to know for sure without taking it apart. Good luck, and thanks for watching.
I like all your videos. Especially those pico projects. Now, Pico 2 is coming, and do you have plans to make some videos on it? RISC-V core might be interesting. :D
I just heard about the Pico 2 today. I've already pre-ordered 2, but they won't ship until the end of August. I hope to learn RISC-V and share it on RU-vid. Thanks for watching!
If all specs match, could i use another brand of motor? Mine is made by Ding Tang...and what i think is the limit switch is made by Toneluck with NO identifying model number on it. Digikey recommends another unit but then there are a million specs to choose from that i dont understand... perhaps i can include a pic of the motor specs or list them here? Thank you again. Fyi, its a ding tang model dtsj-002. Found them on Amazon BUT this repair is more interesting...dcV 29 volts, 75w input, stroke 375-200mm, speed 6mm/s. Max load: 4000N. Max duty cycle 2 mins on, 18 mins off (10%). The motor is only 2.4 years old......
If you can get a replacement linear actuator that fits AND matches the power supply; then I would do that. I couldn't get a replacement for mine; so I had no choice but to repair it. If the motor works, then actuator repairs can be relatively straightforward. However, if the motor doesn't work then replacing the entire actuator is definitely the best option. Good luck!
It can break the bearing housings because the lead screw can drive the nut into either end. Since the housings are made of high impact plastic, these forces (several thousand pounds) will just crush the bearing housings.
@@Handygrrl In my actuator, the nut banged up against one end and cracked the end housing that has the motor attached to it. I was able to repair it; but it is much better to just be careful and only pulse the motor quickly while the nut is not near either end of the actuator rail.
