Hi Phil,
Sovol did not publish their firmware v1.1.4 sources, therefore I won’t be able to find out what went wrong.
There seem to be four solutions:
- Send a problem report to Sovol: info@sovol3d.com
- Ensure a difference of at least 10°C between printing temperature and
M302 Sxxxlower limit temperature. - Try disabled cold extrusion prevention checking:
M302 P1 - I just ran a test using my current firmware version v1.15.7. Extruding at 150°C works when the temperature limit has been lowered using
M302 S140. Maybe it is a good time to switch from the stock firmware.
