14 ohm reduction

Post by craftekdesign » Sat Oct 03, 2015 3:28 am

There are too many variables, but a 30 deg drop aint gonna do it. 14 ohms=40 degrees. It allows for heating momentum in the range of 270. Existing switches were at 12 ohms, way too low.

on a six position switch I would shoot for these degrees. 260, 240, 220, etc.

14 ohms is 220k.

What I have concluded is that you want 260, 225, 213. ALL CAN BE DONE WITH A SIMPLE SLIDE SWITCH.

Values would be 0, 13,16

Remember this:

1 ohm = 2.7 degrees
3.7 ohms = 10 degrees

Carry on woofn it.

The more printer you do, the more temps you will want. Dropping 10C is great for those models you need the support to come away a little better. Gaining 10C is great for those models that are really warp prone and want to crack while printing. I use every single step on my 10 step x 10C temp mod because across all my filaments and the variety of prints I have, they come in handy.

Plus it's cheap and dead easy to print a 10 step 10C mod. Here's mine all laid out for anyone to build http://www.thingiverse.com/thing:528396

I just use the software mod, you can then set whatever temps you want. What is the advantage of having a physical switch?
