I've been using the A8 for 2 months now. Great printer, the extruder set up is one complaint I have. The other being, I wa told you can't convert the A8 to a laser printer. I've just purchased the clone from your link. Once Google translate switched everything to English, I was good. Also, didn't know I could buy off Amazon internationally. When I copy and pasted the extruder type and looked it up in the U.S. Amazon, it didn't give any results. Then when I did find it, the cost was 3x more. So, much cheaper on the German Amazon. Going to remember that for future purchases. I'm going to print your parts now and set it up when the extruder arrives. If this works like you say, I'll be a very happy guy. Thank you for the time you put into creating this.
