I was thinking the same thing. If the carousel is not yet designed then build it such that only a simple translation(s) is required to load the part., no rotation. The reason you buy the general purpose robot other then the simpler automation is that you expect to have other jobs in the future.

If you are buying a new robot then you won't need or want to use LCNC to control it. There is a big difference in robot controls. Look carefully. As mentioned most robot companies will do a simulation for you and make recommendations. If this is for a production machine you need to

The stepgens (both in mesa and the software) have their own acceleration setting. you want this to be 20 to 30% higher than the motion planners acceleration. (when using the stepgen's in position mode) when using high latency systems - then it is best to run the stepgens in velocity mode

One of the most important specs for a robot is the degrees of freedom. If you need to specify the orientation AND location of the end effector you need at least 6 DOF. You can use fewer if you can redefine the problem. What people do today, and you should do to is SIMULATEthe robot before you

eBay item number 141823454594 Or search for "hand wheel encoder" (no quotes) it will turn up quite a few and some of them are black color rather than the bare aluminum color if you would prefer that. I'm wondering these were not intended to be used on an electronic safe as a combination lock.
