Hi guys
can some one tell me what is the differences between these 2 extrudes and if it good idea to buy the v4 even I have working v2 I mean the single head extrude ?'
I have a 24v M2 printer
Doron

I don't think the M2 was ever offered with the V2 hot end? I think they started with the V3A, then V3B came, and currently the V4.

V3A = groove mounted heating element was nichrome wire wrapped and cemented in fire cement. Thermistor mounted on nozzle.
V3B = groove mounted horizontally oriented cartridge heater inside a machine aluminum block. Thermistor mounted inside block.
V4 = clamping style mount with vertically oriented cartridge heater inside a machined aluminum block. Thermistor mounted inside block.

V4 allows you to print materials that require higher temperatures. If you're fine with your current setup and don't plan on printing hotter materials, its probably not necessary to upgrade to the V4.

thanks
