My early version DAV 1.0 mod w/ E3D hotend prints ABS YL filament well at 255.
Yeah , seems alittle high. But, it adheres well w/ no splits.

New acquired DAV 1.0A, 0 hrs, Repetier FW 0.92, Host 1.60 and Cura slicer.
Original hotend.
Same filament, same Cura setup, 1st test 25mmx25mm25mm print at 217. Solid.

Thats a big diff in temp readings.

I may try table 5 as suggested. Though, not understanding this totally.
But know that it doesnt change the temp, but rather how the board reads.
I see in the configuration.h tab, EXT0_TEMPSENSOR_TYPE
Change to 5.
Is that correct ??

The E3D thermistor is a standard 100k, same as the Davinci thermistor.

There's no such thing as a "standard 100k" - 100k thermistors are 100k ohms at 25C, but their resistance at say 200C is a function of their beta value. Your setup is off by 10-20C, you're just used to it. All it impacts is your ability to copy another user's temperature settings and expect the same results.

So the DAV is setup wrong from the factory ? Not being cynical, dont understand why this exactness is focused on imprecise equipment.

For me settings are like 1-10. Different paths for the same result.

Not going fuss about this too much, considering my modded, inexpensive machine prints as well as a $2800 one.
Maybe 1/2 as fast, more down time repairing, but for the money I can buy 6 machines and print 3x faster.

A Da Vinci motherboard however has a 59K ohm resistor in  parallel with the thermistor which changes it's final value at the board and at the input of the AD converter. So in affect the table should be 5 that is selected instead of 1 to compensate for the added resistor. If you do the math the board actually sees 79.5 K ohm resistance at room temp instead of 100K.

I reduced my multiplier from 1.2 to 1.0 and retraction to 2mm and now getting some seriously nice prints. smile
Now, on to PLA .......


Edit : PLA flowing nicely at 210°C and getting great prints with a bit of help from a 12v layer fan.
Really pleased with this upgrade so far, sooooo much less hassle printing PLA than with the stock extruder.

Getting much better results now with ABS at 230.
Next question, I'm seeing a little bit of ooze in places. What settings are you using for retraction and extrusion multiplier/flow rate ?

Thanks. That's not far off what I've been using.

First tests are pretty good with ABS and PLA.
I decided to try fitting it without taking the carriage off and it actually went better than expected.
I tried without raising the stepper but quickly realised it was a no go. I've seen it done on youtube but I've no idea how the guy managed to get the fan in such a tight space.
So I fixed the drilling template to the carriage with a couple of screws and went for it.

Drilling from the front of the printer was fine if a little tight on space to move around.
Then in with the dremel to cut out the space for the stepper.

The stock Davinci heater and E3d thermistor seem fine with no changes to repetier.
I printed a 15mm cube in PLA first. Nice, tight layers but the corners were slightly saggy, possibly due to using too high a temp (215°C).  A layer fan should help too.
So now, on to the fine tuning.
What temps are you guys with an E3D/Lite using for PLA/ABS ?
