Hello I'm (re)drawing a Geared Wade's Extruder for a strap . Using 3mm filament, What clearance must be previous between extruder block and idle roller block for adjustment (dealing with hobbed bold wear and filament elasticity ) ? What is the Wade's design space between extruder body and roller block ? For the moment, I'm thinking to provide 1 mm for wear of the bold and hesitating between 1 or 2 additional mm for elasticity of the wire. Are filaments (diameter 3 mm) HDPE, PLA, ABS sufficiently elastic to be significantly deformed during passage through the extruder (penetration of the teeth and flattening from the roller)? Thanks. https://reprap.org/forum/read.php?4,110379,110379#msg-110379 Mon, 08 Jun 2026 06:38:55 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,110379,110502#msg-110502 https://reprap.org/forum/read.php?4,110379,110502#msg-110502
I'm going to follow the same way with the roller allowed to reach the bolt => 3+ mm stroke]]> nh3oh Reprappers Sun, 18 Dec 2011 16:45:09 -0500 https://reprap.org/forum/read.php?4,110379,110442#msg-110442 https://reprap.org/forum/read.php?4,110379,110442#msg-110442
It does create a problem though; it's hard to load a new filament if the idler block has to move a large (2 mm or so) distance to load fresh filament. Adding a couple washers between the idler block and the main block, on the 4 idler block bolts, will cut the travel down and make loading filament easier. If your printer or craftsmanship is up to it, you can leave less room for error, but my experience has been that healthy error margins are good.
