ok. so ive had the gstar dual extruder for over a year now. i love it a far as the price, and quality.. , its hard to get any info as the company only exsisted on amazon.com. and has no customer service. it looks to be an exact ripoff of flashforge creator...so heres my questions.

1. can i replace, or maybe upgrade the build plate using flashforge parts?
2. my printer says its running 1.o firmware, should i and can i upgrade it? and how

thanks for the help
