        <title>What would be a good upgrade for my hot end?</title>
        <description> This is the printer I have. [makemendel.com]

This hot end has issues, It doesnt hold temp when printing fast and It jams often.

I&#039;m looking for something I can have at my house and ready to print in under a week if possible. I&#039;ve looked at the hot ends from china on ebay and they are a good price but I cant wait a month for shipping. 1.75mm filament prefered.

Sugestions?</description>

            <description><![CDATA[ That looks like an old jhead design in the photo. The mk5 is fantastic and I would thoroughly recommend - however it is much shorter so you will need to work out if this is ok!]]></description>

            <description><![CDATA[ try insulating the heater block. I wrapped my jhead in about 20 layers of ptfe plumbers tape, then a bit of kapton to hold it together. much more consistant temperature now. Might work for you too.]]></description>

            <description><![CDATA[ The current PLA I have needs 225c to look good. My current speeds are 65 perimeter and 90 fill.<br />
<br />
I can go higher speeds on lower prints but if I go higher on larger prints I end up with a hot end cooling down during printing causing problems.<br />
<br />
The resistor in the hot end is 3w, its only 4.5mm, all of the resistors I have found that are possible upgrades are 5.5mm so cant find an upgrade that will fit. I just want to get a hot end to replace this shoddy thing.]]></description>
