Re: E3D on Da Vinci

If I remember correctly, I think E3d instructions said to use table 8 for Repetier.  I am probably wrong, but I thought that was the table used for 0.91.I didn't change anything in the firmware for the E3d thermistor. I assumed that is was basically the same as the stock da vinci. Again,I'm probably wrong, but it seems to work fine in mine. I haven't checked the temp with a thermometer, but based upon how it is printing, it must be reasonably correct. I just added a plug to the E3d one and plugged it into the board from the old extruder. I am also currently using 0.91 firmware.

Re: E3D on Da Vinci

I just installed a prometheus all metal hot end. It has a one piece nozzle/barrel. Not only is it smaller than the e3d v6 but it fits with aj's method amazing well. I used my mk7 drive gear, factory idler gear, and moved everything up higher. With this I didn't have to cut any of the plastic for the fan due to its compact nature. It also only lost  3mm of bed height. I put in -3 in the z home in the epromm and it is perfect. It really is amazing. The heater resistor it comes with heats the hotend ridiculously fast and I am holding a solid 263* right now with some Bridge Nylon I am printing. Not a single jam. I will write a how to later but I would definitely give Eric some business if you don't mind soldering on your connectors. It fits our carriage with minimal work.

I would change out the heating resistor to a ceramic cartridge my self. Those resistors are known to burn out fairly easy. They are not really made to get up to the temps that they heat at. In fact they are not really made to be heaters at all.

Re: E3D on Da Vinci

The testers and maker haven't burned one out so far. I think it will be perfectly fine. I had a ceramic cartridge from fleabay and it was crap in comparison. It was basically a stock replica. 

1x: 5.5x12mm 4.7Ohm Wirewound Resistor Heater (for 12V systems)
is the resistor.

Well I had the opposite problem. I burned out a resistor but never had an issue with 2 of the ceramics I put in my two older printers. So I guess we all get lucky in our own ventures.

Okay  guys, V3 .stl files and pictures are up on thingiverse. I WILL post detailed instructions when I wake up, but I've been up for 24 hours straight and won't be able to correctly convey my thoughts. In the mean time, if any 3D printing pro's want to look over my work and give me some critique, that'd be very much appreciated. On another note, does anyone know how to change thermistor values using the Arduino IDE environment? I bought these thermistors: htt_p://smile.amazon.co_m/gp/product/B00GD471PO/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1 since my stock da vinci thermistor broke. I found the section in the configuration.h files where the thermistor table is, but I have no idea how to generate a new table despite a good 4 hours of research. I've been using these thermistors with the stock davinci table and I know  that is a horrible idea.

There is an M coomand you can issue through a terminal that will autotune the PID of the thermal circuits for both the bed and the extruder.  This is supposed to generate the needed table and store it in the EEPROM.

Re: E3D on Da Vinci

That is M303 S240 for 240* for the Extruder. Unfortunately the extruder autotune for the repetier firmware messes up. I updated to the latest but still doesn't work right. I am always 10-15 under temp with the settings it says but it hits the target perfectly. Restoring them to default and I hold temp +- .7 degrees at 260*

Re: E3D on Da Vinci

I have opted to go with the B3 Pico Hot end. It is a fraction of the size which allows me to create a much more compact carriage.

Off hand does anyone know the exact spacing off the x carriage rails from center to center??

**NOOB** here just wanna say THX for all the info, im actually looking into this mod, got sick of the bad prints.

Also carl_m1968 if you make it with that one let me know im looking for options and that hot end looks epic.

Might be a while, being so small I am having to redo my initial E3D design from scratch and this one has to be direct drive so I can't do a bowden now. My carriage has to include space and mounting for the motor as well. I actually bought the Pico at Microcenter. They are starting to carry some after market parts as well.

Re: E3D on Da Vinci

Offhand, has anyone replaced the thermistor with a thermocouple instead? Just wondering, as this is starting to enter my mind after looking into things a bit more.

The e3D should be able to handle 400C temps, which would open up polycarbonate and other materials....but it would require the thermocouple to do it.

Just wondering.....

The next week or so my plan is to actually finish the e3D swap, as I've finished the things I NEED to print for the next few weeks.

Re: E3D on Da Vinci

As another question, carl, what about something like a Smoothieboard? That's running a similar Cortex M3 processor at roughly 100 MHz, similar to the processor used in the stock Da Vinci board. The only real downside I saw to the Smoothie is that all the stepper controllers are built into the board instead of being breakouts.

The Azteeg X5 mini that I have and will install soon is based on the Smoothie and uses Smoothie Firmware. As for the built in motor drivers, I prefer them to be built in as they are able to use the entire thermal layer of the main-board as a heatsink for better thermal management. The step sticks you find in most boards unless they have heatsinks installed are limited to the mass of the single small PCB the driver is on for thermal dissipation. The drivers built on to the X5 are also capable of higher currents than most drivers. So motor loads put much less stress on them.

So in my opinion as a tech built in drivers are actually an asset rather than a downside and IF by some chance which is doubtful that one or more of mine fail, I can easily replace them where I work at.

Of course this is something to consider if you cannot do such work., but I have worked with the same drivers on another one of Panucatt's controllers and I will be willing to bet that those stepstick drivers on their own carriers will fail before my built in drivers do.

http://www.panucatt.com/azteeg_X5_mini_ … x5mini.htm

My previous controller from them was this one, they however no longer seem to carry it. I never had an issue with it. It was based on Marlin/Sprinter firmware though which is much more common than Smoothie.

I started looking at some of the flaws in the current design and print results and they all point to problems with the head not being controlled well. The head does not accelerate quickly enough nor does it slow down quick enough to do tight or intricate moves. I am sure most of us regardless of our current firmware and drivers have all noticed that the Da Vinci with a direct drive head just cannot make square corners or tight inside corners. This is due to over travel and the heads inability slow down quick enough to make the corners. Of course you could swap out for higher torque motors but that would but more load on your drivers.

I have never liked any direct drive design due to this limitation. This is one reason the Delta machines have emerged recently. Those designers too realized that head weight was a limiting factor. It's up to you, but I would rather have tighter tolerance and accuracy over using able to use flexible filaments.

For the record I am also working on a direct driver version for the E3D I have as well. But he PICO Bowden is getting priority and i don't recall saying I had a specific design in mind at the last discussion of this to be honest.

Have you looked into Taulman PCTPE? Supposedly this is printable via a bowden setup.

Runs in at about $32/1lb spool, which I think is a reasonable price to be honest.

I haven't tried it yet, as I still haven't yet installed my e3D or the bowden extruder, but I'm really hoping that it will work out well with a bowden setup.

Beat ya too it! lol I printed my first test piece in ninja flex last night and it came out awesome! After some more torture tests I will post up the bowden extuder I designed for flexible filaments. It keeps the material constrained for the entire length of the bowden setup unlike airtrippers design.

but the values are not correct
The thermistor installed is 100K Semitec 104GT2 NTC thermistor

Thank You

I'm on the same boat... currently using the default table in repetier (#5), but it doesn't seem completely accurate. For instance, for a real ambient temp of 22ºC the E3D thermistor reads 28ºC.

So no one has created a working custom thermistor table for the E3D and the davinci yet?
