I have a large CNC Mill hooked up to EMC2 and everything is working very well. However, sometimes I'd be happy to be able to print some parts, so I decided I that I need to convert my mill into a 3D printer.

I read here and there, but so far I am not sure that I got evrything correct, so please tell me if my plan works or not:

1.) I Get an extruder Head (I'm not quite sure which one), Heated bed, Electronics to drive the extruder and to controll the hot end

2.) I connect everything to my CNC-mill host computer running EMC2. The extruder has to be configured as A axis.

3.) I control the temperature manually on the extruder, not through the computer

Is that everything? Is it that simple? What else do I have to take into account?

Oh and by the way: I am located in Switzerland. Were should I get the needed parts from? What is the nest source? If possible I'd like to get all parts from a single supplier.

Best regards

Linuxcnc running on the raspberry pi maybe is getting very close to a usable high speed motion controller.

There are 22 IO pins available for running step/dir motor drivers, real time kernel and almost all of the linuxcnc components running correctly.

If you can test this and give feedback to the linuxcnc.org forum it will help speed up the development.

It does not need any extra hardware just plug your stepper drivers into the relevant gpio header pins (thought really I would like people with scopes to send in signal plots and test functions, so plugging motors is not recomended).

Web page for SD card image download is: http://soundproofingforum.co.uk/rpi_linuxcnc/raspberrypilinuxcnc.htm

or you can check the forum thread [linuxcnc.org]

I also posted this in the general topic forum.]]> mung EMC2 Fri, 10 May 2013 06:53:39 -0400 https://reprap.org/forum/read.php?155,178334,178334#msg-178334 Hacking LinuxCNC's HAL layer in to your Arduino (8 replies) https://reprap.org/forum/read.php?155,178334,178334#msg-178334 HAL2Arduino has been released.

Thus, the extruder stepper would be controlled as a 4th axis. First, will these work together? Second, how can I do temperature control?

I have an extra K type thermocouple, could I just use an external temperature controller like this one? Is there some other way to add a thermocouple without having to add an extruder controller? Does the extruder controller simply maintain a constant temperature, or does it adjust based on flow rate? Does it feed back temperature information to the control software, such than just maintaining the temperature with an external controller won't work?

The only extruder controller I could find with thermocouple interface is the makerbot one, but it didn't look like it was really made for stepper motor control, so it seems overkill, but maybe it is the only way to go. I also found the rev 2.2 extruder controller, but it looks like I would have to modify it to work with a thermocouple.

I do not understand how to programme the firmware into the extruder board as there are no straightforward do this , then that, then this instructions it seems that all the programmes need tweaking to my preferences =- which generally are to get the bl**!dy thing to work.

I have built a 3 axis cnc machine run on Mach 3.

I have loaded Umbuto onto my computer and have emc running in Linux using Axis. I have loaded Skeinforge, I have read about 1000 articles but everything end up as a load here add this line etc and is effectively programming.
Does any one have a step by step guide to adding a Wades Extruder to a Mach 3 run cnc. I ran a skeinforge programme through the router that ran the hesd ok including the Z up movement but no reaction from the extruder which id being run from usb port using usb/ttl cable

Thee mach 3 does more that ems has so i am looking to keep m,ack 3 and add the extruder and generate G code through Skeinforge

So, any help gratefully received otherwise you will find a Wadwe extruder on ebay and a suicidal reprap member in Aberdeen!!!]]> inchgreen EMC2 Wed, 30 Mar 2011 04:39:41 -0400 https://reprap.org/forum/read.php?155,72010,72010#msg-72010 Low Latence EMC2 -- Questions -- (2 replies) https://reprap.org/forum/read.php?155,72010,72010#msg-72010
The advantage is that "Puppy Studio" uses a Real-Time Kernel, and the Complete operating system is in RAM AT ALL TIMES. This should have a very small latencey.

"Puppy Studio" is a Multimedia version of PUPPY, but the method of getting the Real-Time additions to Linux are known in the PUPPY world.

It might also be possible to strip out the Multimedia programs.]]> bruce-w1 EMC2 Thu, 11 Apr 2013 23:13:03 -0400 https://reprap.org/forum/read.php?155,71181,71181#msg-71181 extruder bolt-on to CNC mill project. (no replies) https://reprap.org/forum/read.php?155,71181,71181#msg-71181
This is my first post!

I have just acquired a working CNC Mill! Yippie!

Now I want to add an extruder so I can made plastic stuff additively!

The details of the project are here: [mambohead.com]

Here's my mill: [mambohead.com]

As you can see there are several challenges to overcome.

Controller: I guess I need to get some sort of controller for this stepper so that I can connect it to a parallel pin on the controller computer.

Heater: What to get for the heater in the extruder? Does that get controlled by a controller or is there a manual setting on a typical cupcake machine? Do I need to know the temperature? Do I need something to display that?

Software: I’ve been using Sketchup and a few other tools to run the CNC mill. How to control the extruder? Is this the A axis? What does this mean when generating the g-code? What is the required chain of programs to get this done?

Any ideas?

I'm just starting to read this forum so forgive me if there is a known solution for easily getting an extruder onto an EMC2 or Mach III mill.

i have a extruder controller 2.2 which uses a stepper motor as drive.
I want to wire this to EMC2 using the python scripts from sam: [github.com]
To wire it up i use the usb-ttl converter right? or is it easyer to use the rs232 port at the pc and use a max232 to use the uart?
Now my question.
normaly the i2c interface has to be connected to the extruder controll when driving steppers. I dont want to use the mainboard, so how do i tell the extruder controller to use the stepper? Do i have to change the firmware? if yes has someonde used EMC with a stepper extruder before so i can use that firmware or do i have to write it myself?

Thanks in advance..]]> goaran EMC2 Fri, 29 Apr 2011 05:11:14 -0400 https://reprap.org/forum/read.php?155,49647,49647#msg-49647 How to establish a connection EMC2 with RepRap ?

I'm able to get what I think are reasonable prints, but only if I restrict the maximum velocity to around 15 inches/minute (6.35 mm/s). Otherwise, it appears that the acceleration/deceleration of the extruder causes the filament to stretch, leaving thick walls at the corners of an object and thin walls in between. As I understand it, EMC2 should modify the velocity of the A axis (speed of the extruder filament) in proportion to the velocity in XYZ, which in theory should result in the same volume of filament per unit distance, or so I would think.

I've attached a picture that demonstrates the problem. It is a print of Thingiverse 198. Notice how the flat surfaces appear sunken, with the edges taking on a skeletal appearance.

I am wrong to expect the filament width to correctly adjust as the velocity of the tool changes? Has anyone else seen this occur (with or without EMC)? Does this indicate some error in my configuration, or that my extruder is slipping, or it is to be expected for some other reason?

software link

it uses the arduino, or any other hardware. it communicated in the M gcode and request temp readings several times a second. it can also be used to test reprap setup. it works multi platform with WINE install

just look for temp_test.exe file click on it and run!

it will ask what comport your reprap controller or programmed arduino uses

The basic plan is this:

Build an extrusion head using the Arduino based hardware and attach it to the mill.

Write (read: hack together from existing stuff) some firmware for the Arduino that can control the temp, extrusion rate, and fan. The firmware will expect to be controlled via the serial port.

Write implementations of the various M Codes used by the G Code generating slice/dice applications. (Is there consistency here between Enrique's Skienforge and the "official" software back-end?)

Watch it go!

Seems simple enough... I suppose that means it will crash and burn.

----------

If there is interest I'm sure I could publish the Firmware and M Code implementations for others to use.

----------

An aside: Has there been consideration to using EMC2 as an official part of the project? Its a very mature motion control system and, if my assumptions are correct, is extensible enough to drive a RepRap.]]> Anonymous User EMC2 Wed, 14 Apr 2010 16:15:04 -0400
