If we used nozzles that had 1.8 or 1.75 mm opening for the filament to fit perfectly, this would tranfer heat much better and allow for much faster printing speedAnonymoushttps://www.blogger.com/profile/08608293006525492041noreply@blogger.comtag:blogger.com,1999:blog-1024848558336119865.post-18083866029134894702019-02-21T14:43:13.946-05:002019-02-21T14:43:13.946-05:00Have you ever done a filament change through the c...Have you ever done a filament change through the capricorn? The problem is the 2mm diameter path at the nozzle, when you change the filament, you pull this 2mm stud through the whole tube that measures 1.9mm. This marrs up the whole inside. You need to undo the clip, pull the tube out, cut the filament end off, and then you can pull out the filament. It would be much better if nozzle and heatbreak makers could make nozzles and heatbreaks that actually approached 1.8mm.Anonymoushttps://www.blogger.com/profile/08608293006525492041noreply@blogger.comtag:blogger.com,1999:blog-1024848558336119865.post-75119941895118733812019-01-23T17:37:23.284-05:002019-01-23T17:37:23.284-05:00I wonder if you could print a PTFE stabilizer.

Similar to a ferrite core on electronics reducing electronics noise you could have a PTFE stabilizer keeping pressure on all three sides!<br /><br />But that is unfortunate the Capricorn isn't working out.Zaf9670https://www.blogger.com/profile/04813679026777187027noreply@blogger.comtag:blogger.com,1999:blog-1024848558336119865.post-33852065139699619662019-01-08T12:57:08.369-05:002019-01-08T12:57:08.369-05:00I can see that tight bends could be an issue, beca...I can see that tight bends could be an issue, because a tight bend will cause the tubing to adopt an oval instead of a circular shape, which would be more of a problem because of the smaller ID of Capricorn tubing.

The other 3 were brand new 22mm Bondtech pancakes. But again, there was no evidence of skipped steps. <br /><br />Also, several people PM'd me to say that Capricorn does have an issue with tight radius bends. The tool changer CoreXY (the E3d machine) does have a sharper bend than a typical large delta would have, so perhaps that exasperated the issue?SublimeLayershttps://www.blogger.com/profile/03328118878415356059noreply@blogger.comtag:blogger.com,1999:blog-1024848558336119865.post-29100078138312826142019-01-07T18:35:27.794-05:002019-01-07T18:35:27.794-05:00Derek, I am going to hang on to it for a little lo...Derek, I am going to hang on to it for a little longer to do some force testing pushing and pulling filament through it compared to my standard 1.8mm ID and 2.0mm ID PTFE.

The steppers are the standard Bondtech pancakes at .7A. The steppers were not skipping steps. The issue is the "wind up" within the Capricorn tubing after a retract. I don't know if this is typical with Capricorn as I've only ever used it for short (50mm or so) sections to connect "near direct drive" systems. I've done some googling and found many reports of people adding "extra distance after retract" - presumably to account for this. I am not going to go down that path!SublimeLayershttps://www.blogger.com/profile/03328118878415356059noreply@blogger.comtag:blogger.com,1999:blog-1024848558336119865.post-91076851289709853192019-01-07T15:19:32.756-05:002019-01-07T15:19:32.756-05:00Hi Michael, is the filament diameter within a reas...Hi Michael, is the filament diameter within a reasonable tolerance of 1.75mm?

I'm not sure how long the bowden tubes are on the E3D tool changer, but maybe that's the difference? Either way, because one man's trash is another man's treasure, I'd be glad to take the Capricorn tubing off your hands. Let me know! Thanks!<br /><br />DerekAnonymoushttps://www.blogger.com/profile/15224037684574333802noreply@blogger.com
