Mbot grid II dual Hot end replacement


#1

Hi im looking to see what other have done for hotend replacement for the Grid II. I need to replace mine due to a clog and looking at if anyone has replaced the hotends with dual E3d hotends or a E3d chimera and how you mounted it. would like to keep them direct drive instead of bowden but whatever gets my printer back up and working again is what matters. thanks for the help

I was in the same boat recently, clogged with charred PVA. I bought these:


Heat up the nozzles and insert from the bottom to push the clog up and out.
Then clean the needle and insert from the top to see if there’s more. (it’ll catch and push it down again, needle comes out the bottom with resistance or comes out dirty)
Repeat till needle stops being dirty, let cool and try your material again.

Hope that can save you some money.
Edit: DON’T buy the tiny drill bits that amazon has for sale, they break off way too easy. The needles are way better.
