Welcome to the SeeMeCNC Community

the only difference between the new hotend and the one you are using is the PEEK section.. the new peek can use the same nozzle and top section, but uses only a single ptfe liner rather than the double. If you wanted to change to the new style all you would need is the new peek from http://seemecnc.com/collections/parts-a ... nc-hot-end and you would eliminate the double liner.

depending on which hotend you have, the other thing that changed is a thinner heating block, but the new peek can be used in either...

Think I fixed my issue, I ended up disassembling the EZ Struder, drilling it and the groove mount thing out, also I added a washer under the hobbed gear and an extra one over the red lever piece so that the hobbed gear would be dead center with the bearing on the red lever thing, the extra washer over the red lever keeps it from backing off too far, which was a problem with the grinding on my filament.
