I have no idea as to the comparative pros and cons; but, it sounds logical to me. :)<br /><br />In my machine, the print jets are a tiny bit uneven. But, I haven't had any failures since I calibrated using the 1.08B firmware additions. Again, I am using an early build machine and I believe that the head assembly is now slightly different than mine and auto gap should be easier.<br /><br />These are the kinds of issues they can improve over a very short period of time. The engineers at 3D Systems really hop on these things quickly.<br /><br />I do wish the up/down increments were more fine. I have fat fingers. :)<br /><br />Thanks!<br />Tom Meekshttps://www.blogger.com/profile/13580494966261788985noreply@blogger.comtag:blogger.com,1999:blog-7059318635584644192.post-11533921385201098562014-11-12T18:42:01.072-08:002014-11-12T18:42:01.072-08:00Tom,

While the optical auto gap and level is nice it has difficulty with reflectivity and sanding is needed even after a single print for me as otherwise it fails.<br /><br />In my opinion I think 3dsystems should utilize there quick release print jet nozzles and simply have a pressure sensitive manual sensor that can be snapped into where the cartridge nozzle goes, let it do its thing to level and gap, then untwist and pop in the new cartridge. If you need to reset the gap mid cartridge the same step would be applied. Something like a test light would even work so you raise the bed manually on press at a time until the light turns on and presto. I think they overlooked the simplicity and also the beauty of the disposable print head and how that empty void where the nozzle goes could eliminate an expensive and tempermental optical sensor with a tried and true manual sensor.<br /><br />Anyone want to back me up? :-)3dFanhttps://www.blogger.com/profile/06434705137544838748noreply@blogger.comtag:blogger.com,1999:blog-7059318635584644192.post-90919634704997672942014-11-12T18:40:24.057-08:002014-11-12T18:40:24.057-08:00It turns out that not only the height of the wiper...It turns out that not only the height of the wipers might be different for machines built at different times; but, the bins that hold the wipers might show some differences from one side to the other. It's interesting to know; but, not a big issue since we can cut them down, as you suggest, so that they hit only the Print Jet and not the Print Jet housing. I'll let you know when I get the extra wipers with which to experiement; but, even my crudely cut wipers work better than before.Tom Meekshttps://www.blogger.com/profile/13580494966261788985noreply@blogger.comtag:blogger.com,1999:blog-7059318635584644192.post-41170044894170168682014-11-12T07:00:32.098-08:002014-11-12T07:00:32.098-08:00Interestingly, I'd already done that (crudely)...Interestingly, I'd already done that (crudely) and was waiting for some extra wipers to experiment to find the absolutely optimal height. But, the fact that in your machine the wiper height is already different, might mean that the height issue has already been addressed in printers delivered after mine. <br /><br />The method that you suggest, was the one that I used with the Cube2. I just created a small one <.5mm object and made it the first object added to the Cube Client. <br /><br />I like the way you think! :)Tom Meekshttps://www.blogger.com/profile/13580494966261788985noreply@blogger.comtag:blogger.com,1999:blog-7059318635584644192.post-39955954416224271612014-11-11T22:25:47.069-08:002014-11-11T22:25:47.069-08:00Tom,

I think the best fix would be to use a small section of the build plate to make an excess pile then begin printing. Thats kind of what other fdm printers do.<br /><br />As for your wiper, it looks much to high. It should not be bent over being squished by the housing of the jet. Mine is short enough that only the jet nozzle itself touches the wiper and only when the nozzle passes by does it make contact.<br /><br />May I suggest since the wipers are disposable just cut down your wiper slightly....maybe that will help.3dFanhttps://www.blogger.com/profile/06434705137544838748noreply@blogger.com
