  1. After the new "Lost in Space" series came out, I guess that I started having fond memory's of my child hood and decided to go create a toy I never had back then. If you are looking at the photo and wondering, yes, it is floating in mid air. The magnetic levitation system does work nicely. Unfortunately this all the higher it can fly, so making orbit is going to be a bit tricky. The model is 8" in diameter, made on my Ultimaker II+ using Matter Hacker build silver PLA and IC3D natural PLA. I built the CAD model using an old version of Pro-E. When I first started this p
  2. Recently used some Maker Geek Raptor PLA. It is a higher temp PLA that has better structural and temp capability. Printed very clean, for large flat top surfaces made the best finish I have seen yet. Prints on painters tape cleaned with acetone at room temp, and holds on too well, a little hard to get off. I have also had good experience with IC3D PLA. Prints straight to clean heated glass bed with out any trouble, no rafts or brims. Both of these are USA products.
  3. Good point. This is a test part to better show the problem than the real part. The islands that I refer to are in the larger circle, triangle and square, and you can also see the small bars. The small circles are just there to force more travels. Looking at the first layer you can barely see that at the end of the skirt the travel line to the main part is a lighter blue, it would appear that this means travel with retraction. All the remaining travel lines are dark blue, which seems to mean travel without retraction. In the photos as they appear here, the dark blue looks more like a dar
  4. It would appear that I have been having this issue for over a year with multiple versions of Cura. The part I am printing is a name plate. It is 2mm thick with the name cut through it. It is bonded to another part that you can see through the letters that provides a contrasting color for the lettering. For letters like o, b, d that have an island in them I add a small bar across the letter to tie the island back to the main part that is 1mm thick. When I print this the skirt prints, I can hear the retraction, it moves over to the main part, with no strings, and starts printing, and ther
  5. I have been having similar issues. I have been running Cura on my Windows 7 64-bit Laptop that I do my design work on. Shortly after upgrading to Cura 2.7, when I launched Cura I would get a message to the effect “Cura has stop running” and then Windows would offer to close the window. I reloaded Cura 2.7 and it work for a day or so. I then loaded Cura 3.0.3, and it would never start on the Laptop. I then loaded Cura 3.0.3 on our Windows 10 Desktop where it seems to be working. I am not sure but I think the problem started after a Microsoft Windows update. UPDATE: Reloaded 3.0.3 las
  6. Yep a typo, I am running at 260 C, which is as high as my UM2+ can go. Folks that are having success with GD PC seem to be running 270 - 300 C I'll give glue stick another try and see if I can get the first layer to adhere. There were a couple of time I put it on while the bed was still warm, so that might have lead to some of the problems.
  7. Hello, The part above is my first more or less successful print with polycarbonate. This is part of a Yeti mug cap for a friend. While the part is useable, it just barely made it. This is printed from Gizmo Dork PC, on my UM2+. On the first couple of attempts I tried using glue stick on the glass with no success; I would normally abort the print after 15 seconds. I then went to ABS juice, which seems to hold onto the PC pretty good. The first attempt with juice did not have a brim and about half way through it was warping so bad that I again aborted the print. On the print shown here
  8. Note to Moderator: I tried to post this several days ago but it has not shown up, hopefully this is not a duplicate. Please feel free to remove this line. Hello, this is my first post on this forum. I have been working with 3D printing for 2 years now, using my Ultimaker 2. The above photo (which I hope shows up) covers my main interest, which as my user name shows is R/C modeling. This part gave me an interesting problem that I would like to share. The parts shown are part of an R/C model fuselage. The top two have an under extrusion problem, the bottom one is where I fixed it. Thi
