Repsnapper, RAMPS1.3 and extruder settings I am trying to figure out what extruder settings to use. I have been calibrating x, y and z axis movements to change in the firmware. With the current version of Repsnapper if I hit the Run Extruder button my motor just vibrates. My RAMPS is set to 1/16 steps for all axes. Once I change the settings down to around 1600 mm the stepper finally moves. Any recommended setting from anyone? I am only testing with PLA right now with temp around 195 and it does extrude but the settings are elusive as to what I should use. Also I am using Sprinter as the firmware for the Mega 2560. https://reprap.org/forum/read.php?218,94679,94679#msg-94679 Wed, 22 Apr 2026 13:47:03 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?218,94679,109481#msg-109481 Re: Repsnapper, RAMPS1.3 and extruder settings https://reprap.org/forum/read.php?218,94679,109481#msg-109481
I see this is old, so I'm sure you've been up and running for a while;) Let me know if you had to adjust your sprinter settings or if it's a repsnapoper setting.

Thanks in advance.]]> Skypuppet RepSnapper Fri, 09 Dec 2011 12:39:06 -0500 https://reprap.org/forum/read.php?218,94679,94745#msg-94745 Re: Repsnapper, RAMPS1.3 and extruder settings https://reprap.org/forum/read.php?218,94679,94745#msg-94745 mc_n_g RepSnapper Sat, 20 Aug 2011 09:19:21 -0400 https://reprap.org/forum/read.php?218,94679,94732#msg-94732 Re: Repsnapper, RAMPS1.3 and extruder settings https://reprap.org/forum/read.php?218,94679,94732#msg-94732 // e_step_per_unit = 25 and speed =2000 is ideal for repsnapper
I also run PLA at 170. I'm sure none of these temperatures are exact but start low and keep testing by hitting the extrude button
I'm also running the same electronics as you (except V1.2).]]> dean448 RepSnapper Sat, 20 Aug 2011 05:29:43 -0400 https://reprap.org/forum/read.php?218,94679,94679#msg-94679 Repsnapper, RAMPS1.3 and extruder settings https://reprap.org/forum/read.php?218,94679,94679#msg-94679 With the current version of Repsnapper if I hit the Run Extruder button my motor just vibrates.
