hotend got clogged, I took off the hotend and heat the hotend and push pla filement through it. After cleared the hotend fan does not blow any more.
0300-0300-0001-0001
I submitted support ticket and got no response.
The fan is out of order online. I would try a new fan if I could.
Help please.
I had a similar error when clearing out a clog. it ended up being incorrectly seated plug for the fan. the connectors are tiny and can be tricky to click back into place. double check the plug for the fan. make sure its not loose or plugged in wrong.
Have the same issue. Tried the plug and nothing. However if i turn on the fan using the controls on the menu it works fine and can be speed up to 100 percent or turned down. Just keep getting the error message when and the fan wont spin when trying to print.
I have the same problem. I had a massive clog then after cleaning it, I got the 0300-0300-0001-0001 error. I took the hotend apart, replaced the cooling fan for the hotend, and also replaced the extruder connector board. When I try to print, I still keep getting the same 0300-0300-0001-0001 error. When I manually test the fans, they both work fine and I know that the wires are seated propperly.
What it is
The MC module is malfunctioning, and the root cause could be:
- Communication between AP and MC does not work
- The data sent from MC to AP is incorrect
When this issue happens, all operations related to MC will malfunction, such as:
- Move x/y/x
- Set the temperature of hotend and hot bed.
Make sure you plugged the fan into the TH board correctly. It’s very easy to do wrong.
fixed after new fan replacement
I had exactly this issue and have a new fan on order. Why would taking the connectors out and replacing them after a jam be such a problem? Seems like a fairly common workflow…
Welcome to the forum! What happens is that connector will actually go in the plug and either be above or below where it should be. It looks completely normal but it’s not actually making a connection.
Thanks, and yeh believe me I have tried every possible orientation and positioning, power cycle, cleaning etc. Hoping the new fan does the trick… Like others have said, this connection could really benefit from some basic foolproofing!
Yep! Very easy to plug in incorrectly. And somewhat difficult to determine if connectors are fully seated. This is the case with all connectors of this type as they are so very small.
Happened to mine however changin gall components, trying new filament and even contacting bambu labs is doing nothing… I give up
Hope the photo helps (if it actually appears)
That particular fan is not really durable and die quite often.
Just go and buy replacement instead of waiting for support call. It took me 2 months going back and forth with support to get a full hotend assembly replacement. I could get the fan from aliexpress for cheap in about 15 days and had my printer back up working again instead.
