How can I put it ? I print the 20mm tryout printing cube , its perfect , no faults and looks great , I try to print a new hotend fan holder from Thingiverse and the layers are rough like a file on the surface.I have tried all types of tempertures , filament speeds all to no avail . I have never had problems like this before , lucky i suppose !! So settings are 230 hotend 0,4 nozzle and normally press start and always a perfect print . So question was is it the new PLA I have just bought ? Nope I had some left from the old roll same result. Reset Simplify to works original settings just in case , its the same . Any ideas out ther ? Hope so . https://reprap.org/forum/read.php?219,891157,891157#msg-891157 Sun, 16 Aug 2026 12:26:07 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?219,891157,891157#msg-891157 https://reprap.org/forum/read.php?219,891157,891157#msg-891157 zurferjoe RAMPS Electronics Sun, 27 Nov 2022 12:33:11 -0500
