Hotend Clumping X1 Carbon. How I solved the problem

Bambu Lab X1 Series Troubleshooting

Yesterday morning I found the nozzle clogged on my X1 Carbon printer. I made a video and sent in support, I only received a response today. It says that you need to use a hair dryer to heat the frozen ingot of plastic and remove it using wooden sticks.
This method is not always working and depends on the volume of frozen plastic. The first problem with the printer appears here, Artificial Intelligence and Lidar do not work 100% and cannot determine the problem in time.
The second problem is that there is no completely manual control of the printer, there is no choice after turning on the power: Automatic mode or manual mode. In my case, this would very much help solve the problem.
At first I wanted to offload the thread, but that was a mistake. The head of the extruder hit the nozzle cleaning module and the ground funnel for the poop. Then I decided to heat the nozzle to a high temperature and remove the ingot of plastic. But the head of the printer began to move to zero points and hit, as the ingot of plastic interfered.

I turned off the printer from the outlet and removed the back cover to eliminate funnel for poop
After that, turned on the printer and blew out the temperature of 280 degrees to soften the ingot of plastic. After 20 minutes, I removed the ingot of plastic, without using a hair dryer and wooden sticks
I changed the hot end completely to a new one, put everything back in and did all the tests and calibrations. Everything began to work as before.

The conclusion is as follows:

  1. Add fully manual emergency control to the printer
  2. Change the design of the funnel for poop so that you do not have to crumble the back cover completely to unscrew 2 screws. By the way, I had only one screw twisted. This is a factory defect of quality control!
  3. Change AI algorithms to determine nozzle clogging. The hot bed has weight strain gauges/tenso sensors, why it cannot be determined with their help that the weight of the bed with plastic does not increase, although there is a consumption of filament. Why can’t a bed weigh and control the weight of the filament applied?

if you get this a lot try test some Slice engineering liquid. you paint it on the nozzle and it makes it Less sticky. FYI i run 6 printers X1Cs and P1S and across them i have around 12000 hours and have yet to have the blob of death… but all nozzles are coated in Slice

I thought about it, too. I think you can use silicone oil. What are you using for this?

I have been using this product for a month now and not one poop have failed to go down the chute. This includes multiple color project. So far its been good.

Do you use any of the high-temp filaments like nylon or PSS?
