  1. Thank you for your VERY detailed reply and the amount of time you've obviously spent on it. It is very much appreciated. 1) The second second purge line didn't have an extrusion specified because I had assumed it would be inherited from the previous line. Fixed. 2) Re "the hot end goes to 170 for bed leveling": Why? What does that do that my "M104 S{material_print_temperature_layer_0}" doesn't? 3) Intriguing idea re second printer, I'd never thought of that. Done. I've implemented your suggestions but I'm still getting clicking. The fight goes on. The settings in my post were after a _lot_ of trial and, mostly, error to see what would work so I'm not surprised at the lack of quality. Sorry about the delay in responding but by the time I'd posted my query I'd had enough of the printer for one day.
  2. HELP!!! I just cannot seem to be able to hit on the right settings for TPU. What I am getting is extruder clicking. Environment Ender 3 with MicroSwiss Direct Drive Filement ESun Black TPU, temperatures: 210 - 240 Cura settings Flow 50% Layer height 0.12 Retraction 1.5mm 10mm/s Speed 10mm/s Temperatures 230/220 and 50/50 Start GCode M140 S40 ; set bed temperature M104 S230.0 ; set hot end temperature M190 S40 ; wait for bed to reach temperature M109 S230.0 ; wait for hot end to reach temperature M220 S100 ; Reset Feedrate M221 S100 ; Reset Flowrate G92 E0 ; Reset Extruder G28 ; Home all axes M420 S1 Z5 ; Enable bed levelling and set Z fade height to 5mm G1 Z2.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed G1 X5 Y20 Z0.3 F5000.0 ; Move to start position G1 X5 Y200.0 Z0.3 F1500.0 E15 ; Draw the first line G1 X5.3 Y200.0 Z0.3 F5000.0 ; Move to side a little G1 X5.3 Y20 Z0.3 F1500.0 ; Draw the second line G92 E0 ; Reset Extruder G1 Z2.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed G1 X5 Y20 Z0.3 F5000.0 ; Move over to prevent blob squish
  3. EGADS!!! That's a lot to take in. Talk to you in a year or so! 😆 😲
  4. Firstly, thank you for your replies. The attached images are: 1) What the "problem" is 2) What I want (a mock-up) 3) The best I can achieve
  5. The problem: The external and internal walls go all the way to the top - the "top" layer is just an "insert" between these walls. Q: How can I make the top layer a complete "cap"?
  6. See images - they say it all. How can I get some contrast in the entry field? BTW: I'm using an Ender 3 Pro with Ultimaker_Cura-4.8.0-beta.AppImage on Fedora with KDE.
  7. I'm trying to get the "perfect" top layer so I've turned to ironing. The default settings produced terrible results and a nozzle clog. So I've been experimenting but have yet to hit on the settings that give me a better result than that achieved without ironing. See the attached image for my settings. HELP! BTW: I'm using an Ender 3 Pro with Ultimaker_Cura-4.8.0-beta.AppImage on Fedora.
