Problems with my PowerSpec Ultra 3D printer?

[jeffmorris]

I set the extruder temperature to 240 degrees but the display shows the temperature of about 235 degrees. I have all-metal hotend. I hope that the print will not fail. There is an online store that sells parts for Flashforge 3D printer at https://www.bilby3d.com.au/DispCat.a...1&SubCatID=133 Is this store good or bad?

Your fan's cooling power is greater than your heaters heating power and its reaches its ceiling at 235 degrees. Either get a slower fan, deflect some of the air flow and get a heater with a greater wattage. BE AWARE: Do the last option wrong and you will burn your house down. These desktop printers have ZERO safety features.

I've noticed that if you have a cooling fan blowing on it the all metal setup combined with stock PID values let any temp of 240 or beyond sag a bit. My solution was to insulate the heat block and nozzle with a bit of insulation with adhesive from Carl Raffle's shop (raffle.ch). And I bumped up the I value in the EEPROM.
