Hi, I have a ez-router scorpion cnc that has 5.1 Cuken planetary gearbox. I’m wondering if there are any alternatives that may work for me? To order one from ez-router is $1000. Ordering direct from the company in china is $189 + freight but it’s very hard to get ahold of them as you can imagine. Here are the specs of the gearbox http://www.precisiongearbox.com/html_products/PF80-SERIES-PRECISION-GEARBOX-SERVO-SPEED-REDUCER-133.html
