Well my Darwin running the lateset firmware for the stepper extruder is doing everything it is supposed to except turn on the extruder stepper motor. This is teh one hurdle left. Now the enable pin is set as pin 5 which conflicts with the fan. Now I tweaked the firmware to use one of the many other pins on the Arduino Mega I am using. I get nothing. I have re-wrote things every way I could think of. I am using Gen 2 electronics with a Gen 1.2 stepper board for all axis and the extruder. What am I missing here???

Yes I tried that too. I saw previous posts where this was suggested. It might have even been you :)

I got the 5D firmware forked for the Mega that Wolfgang sent me to compile so I think I am going to rewire to the pinout called for in that firmware and see what happens. (Thanks Wolfgang)

Any other suggestions would be greatly appreciated. I'm getting closer. I'll keep you all posted

Thank you so much

That seems odd. They should be on and begin flashing when you hit extrude in the host.

I'm not exactly sure how the enable signal is managed, but it might be backwards in your setup. Try connecting the enable signal to ground or +5V and see if you can get it working.

I just downloaded it. I have not tried this one. I have tried a few 5D that are supposedly forked for Mega Support. I can never get them to compile. I will try this one. I'll keep you posted

Firmware 1.4 help]]> Stoffel15 Reprappers Thu, 04 Mar 2010 08:51:24 -0500 https://reprap.org/forum/read.php?4,37636,37880#msg-37880 https://reprap.org/forum/read.php?4,37636,37880#msg-37880
The latest Host 1.3
Firmware 1.4 set for Arduino
Arduino environment 0017
Adruino Mega Processor
Gen 2 Electronics
a Stepper extruder using the thermister/temp sensor, PWM board that came with the Gen 2 electronics, and Stepper controler board 1.2

All electronics have been tested and re-tested and re-testeted usinig various test programs. Everything works. When I hit extrude in the Host the stepper driver lights go out meaning the enable pin unlocked the coils. I am getting no step and direction. I even hooked it up with a DC Motor and DC motor controler and I am getting no speed or direction pulses. That is where I am at I no signals going to the extruder to tell it to step and what direction. I have tried diffrent pin assignments, I have sent all of the Axes data cables to the extruder stepper board and it works flawlessly. It is like I am missing something somewhere.]]> Curlrup Reprappers Thu, 04 Mar 2010 08:17:42 -0500 https://reprap.org/forum/read.php?4,37636,37841#msg-37841 https://reprap.org/forum/read.php?4,37636,37841#msg-37841
Let us make a secound try. but..., From where you are ? I am from germany.


First, we need information.

Say what you have best, with a link to show.
Show me a link to the Firmware you use...
same with the software (host)
do you have a Digitalcam ? Make a picture from what you make there.

You use Windows ?

Then i have enough information, and i think the other too. and we can try to help.

Code added to GCode_Interpreter to support stepper-driven extruders. The ordinary DC motor speed (pulse = step) and direction (= direction) pins also drive the stepper. Ther is an additional stepper-enable pin defined. Set this -ve (the default) to not use a stepper drive. Set it to the enable pin for the stepper to use one.

What is -ve? And when they say set it to the enable pin for the stepper to use one they just mean plug in the number of pin the enable for the driver is hooked up to right?

Sorry if I am asking basic questions but I am learning a lot of programing as I go here.]]> Curlrup Reprappers Tue, 02 Mar 2010 22:59:18 -0500 https://reprap.org/forum/read.php?4,37636,37746#msg-37746 https://reprap.org/forum/read.php?4,37636,37746#msg-37746 -------------------------------------------------------

Right sorry I was just reading up on how the DC motor was hooked up in case there was some nugget of info there. Yes not speed but step on 26 and direction on 24 pins of an Arduino Mega. The board also works fine I plugged every axis data cable into this board and tested both directions the board works flawlessly. I'm stumped. I also did not get any kind of LED change until I downgraded to host 1.1 from 1.3.]]> Curlrup Reprappers Tue, 02 Mar 2010 20:13:06 -0500 https://reprap.org/forum/read.php?4,37636,37738#msg-37738 https://reprap.org/forum/read.php?4,37636,37738#msg-37738 -------------------------------------------------------

Right I think that is for Gen 3 electronics. I have Gen 2 with a PWM board, and temp sensor board, and a stepper controler.

first, a stepper has no speed pin. as faster the signals are on the Step-Pin as faster the motor is. The secound pin is the DIR (turn left, turn Right)
