Hi all, I’m wanting to replace my hotend rods (the bit you put ptfe tubing in) and I can’t find any on aliexpress or ebay that look like them. The nozzles it uses are Mk8 but all the Mk8 rods are threaded all the way down the exterior where as the original ones I have are threaded at the bottom end only and smooth for the rest. Sorry no pics as I find taking the print head apart pretty annoying. Also I have found my printer prints better if the ptfe tube is all the way into the extruder where as these threaded ones appear to come with it already in but cut to the rod length only. Any ideas where I can get hold of these?

You could try looking at the Wanhao website. The Duplicator 4X is basically the same printer as yours so the parts should work on your CTC Dual. You can check it out here http://www.wanhaouk.com/collections/duplicator-4-parts

Hope you find what you’re looking for!

Was wondering what length I should be looking for as the wanhao site only has the fully external threaded ones?
