Hi. I have the kit for 3 days only and experiencing magor clogging issues on long prints. On some point during the print extrusion stops. I tried everything. After uload and reload filament it start working but get blocked again after 2 hrs of print. I am printing with Prusa branded PLA and used multiple slicers with Prusa recommended settings. I was told by someone who had similar issue when his printer was closed in inclosure and solved it by leaving it open during print with PLA. I too have the printer in enclosure and wonder if this really can cause the issue. The cold end is cooled by stock prusa fan that us working fine. Please help.
