Got my new E3D All-Metal Hotend V4 - (Updated with Mounted Pics) (Page 7 of 9)

Just got my E3D and have it put together and will install it soon.

Does anyone have a line on where to get the connectors that SD uses on the SD3 for the thermister (can the SD thermister be used in the E3D?) and heater?  Would like to just be able to plug into those rather than having to run new wires all the way to the board.

BTW this page lists those connectors:

Connectors
The original hotend connectors are TE Connectivity MTA-100 connectors. The color corresponds to the wire size.

Can anybody list their printer and slicer settings for the e3d 0.4 mm extruder. I like to use them as a starting off point if possible.
Thanks.

Thanks Adrian, yes I tried to set the thermistor settings different as well as the maximum allowable temperature, I had a no-go with the upload to the ATmega644P I used all the instructions I found on-line recompiled without a problem but then the upload fails "avrdude: stk500() programmer not responding. So am using the old settings for the time being.

I downloaded from the google repository, Arduino 1.0.5 with Solidoodle Marlin built in, is that not the right one?

The e3d instructions tell you: "You must also wire up the fan directly to your 12v power supply. Do not use a “fan” output from your controller board. The fan should be con- nected directly to a 12v supply so that it is always on - as the HotEnd needs constant cooling when in use." The one thing they don't tell you is that the fan must be wired correctly. The Solidoodle leads to the fan on the extruder stepper are not colour coded so hard to tell which one is + and which one is -. I used the same wires to hook up the e3d fan. If the fan does not turn, reverse the wires and magically it will work. Just a heads up....

Cool. I'm just testing a few things - but question - when did you get your SD delivered ? there was a batch of Atmega 644's SD shipped that were missing bootloaders - meaning they can't be programmed via any IDE and need first to have a bootloader reprogrammed using another arduino or an ICSP programmer off of ebay...

The symptoms you describe are the same as having no bootloader - does your solidoodle connect instantly when you click 'connect' or does it 'pause' for 3 or so seconds ? If its instant-ish (like within 1 second) then you don't have a bootloader...

BUT.. there is also a vague possibility its the ancient bootloader used.. which I can fix.. but I need a bit to test it first so will probably be later today or tomorrow before I post that (if I have to, still testing)

Changed the max coms speed to 38400 and at least the message from avedude changed, now it is: Yikes! Invalid device signature. Double check connections and try again, or use -F to override this check.

BTW when you say connects immediately you mean via Repetier host? Because it takes a while.

Anyone have a 3d model of the E3D hotend.  the website has a place to download it but the download doesnt work.

Umm, it is true. I hate to disagree with yourself in particular ysb, but what you state is not actually correct.
Whilst your version of RH can influence the overall connection of the program - the Pause delay on connection is determined by the Arduino Bootloader. Every time your Sanguinololu or equivalent board resets, either by pressing the button, or connecting via serial (as RH lowers DTR which causes a reset unless you change this in printer settings) - the Bootloader runs. This will cause a 3-5 seconds(depending on bootloader) pause before the Arduino sketch (Marlin in this instance) runs.

To avoid the Arduino resetting, you can either set RH to not lower DTR, or remove the Reset jumper on the board (if yours has one).

But with a stock setup, and a Bootloader installed, it WILL pause - RH wont connect when the Bootloader is running and the bootloader will continue to run for 3-5 seconds and THEN load Marlin ..... no ifs or buts about it. If it doesn't - then you have switched off DTR lowering, You have removed/replaced the Jumper, or your board does not have a Bootloader installed.

Non-Arduino compatible clones can often have a jumper for the bootloader trigger - bootloader still runs first but will see if a pin is low/high and immeadiately load the program based on that pins status. The new Printrboard is like this.

Any changes in connection between RH versions is either a result of changes to DTR, or purely perception.

If you still believe its not true - please elaborate on how your bootloader within your MCU knows to load or not when you reset the board - this is fundamental to how Bootloaders that allow sketch upload to work function. If you are getting *instant* connection to your Arduino, you *must* have disabled DTR lowering through software or hardware (and thus no reset and no bootloader ran), OR don't have a bootloader.

Hummmmm.. that's strange.... with my original board [sanguinololu].. this 3-5s delay was there...
Then i switch to ramps 1.4... i have a bootloader in my arduino 2560... it's sure [i load the firmware thru the usb like the original board]... but with the new RH, the connection was near instant...  perhaps the default mode of Ramp board is with this DTR jumper thing you speak about? ... your arduino -fu is a lot better that mine... so it's probably related to my ramps board but i'm near sure i changed my RH version after i changed my board...

Reading through here and from personal experience, this seems to be a common problem.

The E3D hot end hides nothing, and is prone to showing the pattern you describe. This is because it's better however. I will update my stepper like others and report back.
