Ok, with the advice of BR549 and Chaoticone I fiund some areas that need addressed. First, is the noise. I have added some further protwction against that and will be implementing that when I get to that point in the build. I have to admit, I knew it was an issue, but chaoticone made it clear that its a bigger issue then I originally thought. He also stressed and restressed the importance of proper planning and research. I have been designing and researching for about two years before I started actually building. I am far from being a knowledgable source on the topic, but I think in that two years Ive learned enough to get my feet wet, and continue my learning experience hands on. BR549 opened my eyes to the weight of the gantry, which made me rethink the design on that. So far, I have taken( in design) the weight from about 200 lbs down to 120ish lbs. I am in the process of alternate gantry plates from thinner material. Those 3/8" plates weigh about 28lbs each. So that is definately another area I could shed some weight. As soon as I get time that is my next step in the build. Also pointed out was gear reduction, and have researched and calculated a 3:1 reduction would suit my needs. I have already started looking around for the 3" DP 20 Pa 20 pitch gears I will need. Does anyone know of a good source for these gears? All I can seem to find are very expensive prices for a simple little spur gear. And the THC, was also mentioned as a problem area. I am hoping it will suit my needs, I will be cutting thicker plate most of the time. According to Hypertherms tables the fastest I will ever need to cut at is 150ipm. Im hoping that proma can keep up. If not, then I will cross that bridge when I get there.
