It sounds like with attention to detail, I could probably plan tool paths to minimize the risk that a slip related position error will go into a job as long as it stops the job after it happens.
That will be, as a CNC operator, your main task. No matter what machine you purchase
I think with a little more research I'll be able to at least know what to ask and to see if a closed loop system is worth the upcharge, or if the other options are.
I don't think either of those 2 mfgr's offer a closed loop option. I do know that the closed loop drives that I use would not fit into that size control box.
May I ask what the increase cost of going with the closed loop was on your acorn project?
You may ask, I will not answer. The number would not be applicable. My costs include parts, machining, wiring, relays and programming related to a different control system that are all part of my standard system. I don't produce machines that are not equipped with higher end closed loop stepper or servo systems. What is or is not included in a custom system that I build a half dozen a year of is totally unrelated to mass produced entry level machines offered by OEM's. In most cases the options you seek are only offered on larger frame model lines.
