Creator Pro under extruding

[terrydactyl89]

My Flashforge Creator Pro has suddenly started under extruding. I've taken out the stepper motor and cleaned it, and the problem persists. When I had the motor off, I had a look at the nozzle and it may have been clogged. I'm not 100% sure though, this is the first time I've run into this problem on my printer.

Any advice on what to do, or what I should look at in this case? Currently printing using PLA at 230 degrees, if that makes a difference.

PLA at 230°C ? That's hot. You probably have residues creepingly blocking the hotend.

I use a metallic brush strand when I have doubts about hotend clogging. Avoids disassembly.
