I am trying to reverse engineer a CreatBot controller in order to install an updated version of Marlin. I am able to get Marlin on but all the pins are wrong. I manually traced the the stepper and limit switch pin connections using a multi-meter but it just won't work. I also tried disassembling the hex but all the characters were stripped. The machine really is well built and otherwise excellent, what is the best path forward? I heard there was a way to actually decompile a hex, thought not fool proof. Any tips? https://reprap.org/forum/read.php?219,834953,834953#msg-834953 Mon, 12 Oct 2026 05:01:06 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?219,834953,835114#msg-835114 https://reprap.org/forum/read.php?219,834953,835114#msg-835114 Dust RAMPS Electronics Mon, 01 Oct 2018 01:14:11 -0400 https://reprap.org/forum/read.php?219,834953,835106#msg-835106 https://reprap.org/forum/read.php?219,834953,835106#msg-835106 Arduino/Genuino mega or mega 2560 board in IDE? I imagine that should work on any 2560 based controller, right?]]> Modmike RAMPS Electronics Sun, 30 Sep 2018 20:58:00 -0400 https://reprap.org/forum/read.php?219,834953,835105#msg-835105 https://reprap.org/forum/read.php?219,834953,835105#msg-835105
there is no "if it doesnt get a response" stepper drivers have no feed back.

It just looks at the time, for some of the time it moves steppers in one direction, or it reverse the direction.]]> Dust RAMPS Electronics Sun, 30 Sep 2018 20:56:03 -0400 https://reprap.org/forum/read.php?219,834953,835104#msg-835104 https://reprap.org/forum/read.php?219,834953,835104#msg-835104 Modmike RAMPS Electronics Sun, 30 Sep 2018 20:27:37 -0400 https://reprap.org/forum/read.php?219,834953,835044#msg-835044 https://reprap.org/forum/read.php?219,834953,835044#msg-835044
Is this correct?]]> Modmike RAMPS Electronics Sun, 30 Sep 2018 08:14:31 -0400 https://reprap.org/forum/read.php?219,834953,835009#msg-835009 https://reprap.org/forum/read.php?219,834953,835009#msg-835009
no intelligence, no safeties, just turns the correct pins on to moves all stepper back and forward and mosfets on and off]]> Dust RAMPS Electronics Sat, 29 Sep 2018 20:41:31 -0400 https://reprap.org/forum/read.php?219,834953,835008#msg-835008 https://reprap.org/forum/read.php?219,834953,835008#msg-835008 Modmike RAMPS Electronics Sat, 29 Sep 2018 20:34:31 -0400 https://reprap.org/forum/read.php?219,834953,835007#msg-835007 https://reprap.org/forum/read.php?219,834953,835007#msg-835007 reprap.org]

far quicker to compile

avoids issues that are not related to pins (incorrect steps/mm, feed rates, not working endstops, etc)

try your measured pins with that.]]> Dust RAMPS Electronics Sat, 29 Sep 2018 20:33:04 -0400 https://reprap.org/forum/read.php?219,834953,834953#msg-834953 https://reprap.org/forum/read.php?219,834953,834953#msg-834953
