Hi - I hope this is the right place for this question. I'm a huge noob but I'm going to order an ACRO system. I just have a couple questions before I order though. 1. I noticed the z-axis is only 2.75", which will be fine for me to start, but how difficult would it be to increase this? I'm just learning about everything still, so a very basic answer is fine - as long as I know it can be done without spending too much money. 2. I see the kit has a plate that can mount various routers, but I'm not able to find any brackets in the parts store. If I were wanting to cut exotic hard woods and acrylic, would a Dremel be sufficient? Any help in this department would be appreciated!
