inspecting parts these are the ‘y’ travel rail ends that the rods fit into… these should be metal not printed parts with a allen screw tightening !!!.. they are supposed to be in a real bushing or a true hole press fitted not a plastic hole i noticed my ‘y’ travel is stiff … we measured the distance between the rails and there is about a 1/2 mm difference… do ya think is because of a sloppy hole plus the allen screw tightening from one side and is pushing the rail as it tightens to a loose plastic hole changing the distance between the two rails enough to make it a tight travel…yep happens every time… these are very important parts for accuracy and smooth travel somebody please inform the engineers but i’m sure they must know plus a real metal part would cost a little more… but so what makes for a better product!
Based on all your posts, which seem to have a similar theme, I have to wonder if the TAZ is really the printer for you. Perhaps you can still return it? I’m not sure what you’d find suitable for a replacement, but I’d suggest you look at the commercial units – perhaps like a Stratasys unit?
very possible but i haven’t given up yet i still have faith i’ll know more in a few days on what i can live with… i have an excellent old school machinest that helps me when needed and am having him look a few things over … i have had him help me make several special fixtures for my cnc mills and other things … i took a video on my phone today from the shop but can’t post says it’s too large it’s only minute how can i post it i really want to share it you should find it interesting thanks
