Hello all, I am new to this 3d printing world as I just recentely purchased a Reprap Prusa i3 printer from Ebay, My printer is the acrylic frame model. Everything went well with the build and I am happy with the printer other than the need to replace the Y axis acrylic subplate with a aluminum plate. My question is: I have used both Cura and Repetier for my slicing and both slicers will show a total time to print the part, I have found this number calculated to be way off, Just last night I went to print a file and the time calculated was 4 hours, 7 1/2 hours later my part was completed. Am i missing something? is there a way to get a more accurate build time? The time will update if I change layer height, fill amount, etc, but the actual printing is always a considerable amount longer than the software calculated time.

Max print speed is set to 80 but I actually don't print anything higher than 50. Moves can be higher as the are not printing. So in this case would I get more accurate speed predictions if I set max print speed to 50.
No need to actually print just see if the time prediction changes. If it does then this may help us reduce the error. I thought slic3r had a parameter to adjust the time prediction.]]> MCcarman Prusa i3 and variants Tue, 03 May 2016 08:52:28 -0400 https://reprap.org/forum/read.php?406,657408,659260#msg-659260 https://reprap.org/forum/read.php?406,657408,659260#msg-659260 ScottB66 Prusa i3 and variants Mon, 02 May 2016 06:32:43 -0400 https://reprap.org/forum/read.php?406,657408,657728#msg-657728 https://reprap.org/forum/read.php?406,657408,657728#msg-657728 gcode.ws] to get a more accurate calculation of the time.]]> SteveRoy Prusa i3 and variants Wed, 27 Apr 2016 22:39:27 -0400 https://reprap.org/forum/read.php?406,657408,657541#msg-657541 https://reprap.org/forum/read.php?406,657408,657541#msg-657541 broy55 Prusa i3 and variants Wed, 27 Apr 2016 13:33:24 -0400 https://reprap.org/forum/read.php?406,657408,657408#msg-657408 https://reprap.org/forum/read.php?406,657408,657408#msg-657408
