My conversion kit showed up late last night, but haven't had time to open it yet. Waiting for the shed to warm up.Same here. What do you guys think about the 16mm Z axis ball screw? Do you think it's sufficient for the Z axis load?
The analysis Alan pointed to looks complete. There are a lot of factors going into "is 16mm large enough". As in most design many of the factors are fuzzy. For my one off designs the cost (time) in doing these calcs is more than the cost ($) of going up a size. So, if I did the conversion myself I'd go with a larger ball screw (if it fits). Is it needed? I dunno. But, PM took enough time releasing the kit that they could/should have done these calcs (and tested, and tested, and...). For a production design I'd be surprised if they didn't. Thus, I'll assume their kit (with 16mm Z ball screw) is OK until it gives trouble.
Exciting times. Stay safe and healthy.
