Hoping to determine the reason for my inability to print over ~270 °C on my Anet E10.
To date all operation has been fine. Attempting to move to a configuration that supports above 250 °C up to ~300 °C.
The control board is the default V1.5 with no changes purchased ~Aug 2019.
I use OctoPrint to interact with the printer.
When attempting to print with a temperature > 270 °C OctoPrint shows it is stopping with a "maxtemp" error. The same "maxtemp" error occurs if I just set the settings to 270 °C and let is sit there for a couple of minutes at most.
This occurs with or without the bed being heated.
I can print successfully at 260 °C with or without the bed being heated.
I have changed the thermistor to another 100k glass bead and a 100k within a canister. There where no changes in the ~270 °C "maxtemp" stoppage.
I have also changed the heater from what was there (30 W I believe) to two different new 40 W (resistance of about 4.1 Ω) without a change in the ~270 °C "maxtemp" stoppage.
The power supply seems not to be involved here since "maxtemp" stoppage occurs without the bed being heated.
I believe this is solely the reason that the control board has a "maxtemp" set at 275 °C. (but I don't know this since I can't find a statement that the V1.5 has this setting by default).
Is there something I am missing in this scenario? It seems I need to flash the board with settings that have maxtemp > 275 °C - say for my needs ~300 °C.
Regarding the hotend, I neglected to mention and should have, that I have upgraded it to a Micro Swiss in preparation to print over 250 °C.
