One big difference is the reduction in noise, it runs so much quieter with repetier.
And because it controls the motors properly, you'll see an increase in quality too.

Would you all put E3Dv6 in that same category?

Yes, I am happy with a the e3dv6. It allows additional versatility that the stock head cannot compete with.

The e3d has been great for me. it takes a lot of dialing in, but I can finally do reliable PLA, semiflex, and taulman

I have the 1.0A and use table 5 with my E3Dv6. It works well for me and my temps seem to be VERY similar to when I was using the stock head. I was worried about this initially but really it does not matter as long as you know what your print settings/temps need to be.

Personally I wouldn't mess with the resistor. Good luck if you proceed, lots of good folks here that may know more about the one to remove.

I didn't find I had to mess with resistors, just swapped the stock thermistor out for the E3D one.
Didn't change anything in repetier either.
But it's an original Dav 1.0 I have.

Is this always required, or do only some thermisters present this problem?

Your board looks identical to the last one in this thread:

Does this board have the large or smal SDcard? I believe the black and blue wires where the thermistor. Based on that I would say R27 is your target going by the traces.

I use the following settings in Repetier .92 they give an accurate temperature at 230C. At room temperature (20C) extruder shows 10-15C. I gave up on getting it accurate all the time as long as it's accurate at the print temp I don't care anymore Lol.

Or am I completely off and it's on the breakout board?

This is the resistor I (think) is the one I should remove - but its not there?

Maybe it's a different resistor number (e.g R99) instead of R29 for the 1.0A mainboard

EDIT: I've done some resistance checks on these resistors. This is what I found:

R125 - ON:99ohm, OFF:99ohm
R27 - ON:996ohm, OFF:549ohm
R29 - ON:NO CONTINUITY, OFF:656ohm

Hi!

I was about to remove the resistor R29 so that I can get accurate temperatures with the V6 but it looks like there is nothing there? It's a white dot.

I'm looking at the bottom of the board below the ATMEL chip - is this the right place?

I'm stumped & have no clue what to do now

Thanks in advance
Brad
