EMC2RepRap Extruder Controller is working Hello, i did not want to use the buggy reprap Host any more so i built some simple electronix that will work with EMC2 All you need is these electronix and 4 stepper drivers Extruder_controller_display_medium.jpg mod_embed_images_loadimage('9504c0d61c7572e28aa0a3c26d4ebaf6', 'https://reprap.org/forum/addon.php?13,module=embed_images,url=http%3A%2F%2Fthingiverse-production.s3.amazonaws.com%2Frenders%2F94%2Ffb%2F3b%2F57%2F59%2FExtruder_controller_display_medium.jpg', 'http://thingiverse-production.s3.amazonaws.com/renders/94/fb/3b/57/59/Extruder_controller_display_medium.jpg', 'https://reprap.org/forum/addon.php?13,module=embed_images,check_scaling=1,url=http%3A%2F%2Fthingiverse-production.s3.amazonaws.com%2Frenders%2F94%2Ffb%2F3b%2F57%2F59%2FExtruder_controller_display_medium.jpg', '', 83439, 800, 400, 'Loading image ...', false); The steppers are directly connected to EMC2 The temperature controller is connected via RS232 A video of the whole stuff can be seen here: [www.youtube.com] and all the files to built this that are needed are on thingivers [www.thingiverse.com] some documentation will follow. https://reprap.org/forum/read.php?13,83439,83439#msg-83439 Tue, 14 Apr 2026 02:36:12 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?13,83439,83687#msg-83687 Re: EMC2RepRap Extruder Controller is working https://reprap.org/forum/read.php?13,83439,83687#msg-83687

I am assuming that the above means that your parallel port is connected to stepper drivers then the stepper drivers are connected to the stepper motors.

This assumption is correct, The board above makes up for the remaining required functionality, like temperature control.]]> Traumflug Controllers Sat, 14 May 2011 01:15:01 -0400 https://reprap.org/forum/read.php?13,83439,83680#msg-83680 Re: EMC2RepRap Extruder Controller is working https://reprap.org/forum/read.php?13,83439,83680#msg-83680

What hardware (stepper drivers) are you using between the parallel port and the stepper motors.

the host is really buggy and the communikation too, so i replaced them with EMC2

EMC2 has undoubtly it's advantages, but for solving the communications problem a different G-Code sender whould have been sufficient ;)

EMC2 controlls the steppers via direction/step pulses over the parallel port.

What hardware is required between the parallel port and the stepper motors?

The other electronix is just different Versions of the reprap electronix, the gen3 is the default, but its old, the new ones with the pololu are better. all these electronix have in common that teh interpolation of the axis is done in the microcontroller and the pc only sends the gcodes.
I had some gen3 electronix too, but the host is really buggy and the communikation too, so i replaced them with EMC2, now everything is fine.]]> goaran Controllers Fri, 13 May 2011 02:15:46 -0400 https://reprap.org/forum/read.php?13,83439,83568#msg-83568 Re: EMC2RepRap Extruder Controller is working https://reprap.org/forum/read.php?13,83439,83568#msg-83568 I am currently undertaking a prusa build and have yet to source electronics. I don't really understand the difference between all these different controllers (ramps, gen3, gen6) and using EMC2. How does EMC2 communicate with the stepper motors? How much electronics is required? What are the pros and cons for controlling my machine with EMC2 or with for example RAMPS. What about costs is EMC2 cheaper?

Thanks

As disadvantages go, the point which is unclear to me is what emc2 pc connectivity solution would be cheapest / simplest in the absence of parallel port. I got to pass to fpga cards and such, etc which is my own big turnoff point.]]> NoobMan Controllers Thu, 12 May 2011 06:41:21 -0400 https://reprap.org/forum/read.php?13,83439,83499#msg-83499 Re: EMC2RepRap Extruder Controller is working https://reprap.org/forum/read.php?13,83439,83499#msg-83499
i think this methode has many advantages over the original reprap electronix

- it can be used for heavier machines espacially when repstrap like hybrid cnc/reprap machines are build because EMC2 moves the axis smooth with acceleration ramp much better than the reprap electronix do, which also increases the maximum speed that is possible.
- EMC2 is stable and has lots of options for optimization as well as a live view of the printing process in 3D
- all the communication that has to be done over rs232 is the Temperatur management, the electronix support 3 temperature sensors and 3 FET outputs.
- its cheap, only one small atmega8 board needed (and the stepper drivers)

Disadvantage is that alwas an PC is needed and it does not support printing from a SD-card.]]> goaran Controllers Thu, 12 May 2011 05:53:57 -0400 https://reprap.org/forum/read.php?13,83439,83495#msg-83495 Re: EMC2RepRap Extruder Controller is working https://reprap.org/forum/read.php?13,83439,83495#msg-83495 NoobMan Controllers Thu, 12 May 2011 05:21:52 -0400 https://reprap.org/forum/read.php?13,83439,83439#msg-83439 EMC2RepRap Extruder Controller is working https://reprap.org/forum/read.php?13,83439,83439#msg-83439

The steppers are directly connected to EMC2
The temperature controller is connected via RS232

A video of the whole stuff can be seen here: [www.youtube.com]
and all the files to built this that are needed are on thingivers [www.thingiverse.com]

some documentation will follow.
