wow nc cams. that was an interesting read. (if it made since to me). but the thread i am referring to is not the one lakeside posted. the mods and a few others know which one i am talking about. it had to do with some problems and ended up with a few idiots trying to start trouble and get their post count up. to answer some of your questions.
dynacnc plasma machine. servo motors. thc.
don't know anything about backlash. bought table turnkey. would have thought that was set up buy dyna.
don't know if i have look ahead either. explain where to find it on my computer or what program do i need for it. sheetcam, and mach 3 were installed for machine from dyna.
have no clue about rf noise, or sheilding. please enlighten me.
found a company. bought a table. was told you don't have to know much to run one of their tables. so if everything you posted is possible problems, boy did i get suckered. the salesman never mentioned anything about, you need to backlash this, or rf that. i was told, send money, computer and wait until we are real good and ready to send you a table and then call this # everyday for our tech guy to help you rebuild it at your shop and fine tune because when we send it, that means it ran perfect here. to which we have done since we have it. so thanks for your help, but that is not the thread i was talking about. we won't get to see the one i started this thread about ever again because someone got his/her feelings hurt

with that being said, now you know alittle more about my machine. please explain in alittle more detail about your post. i am totally ignorant with cnc. but have learned alot just by tooling around with this thing.
