And a rocket Xmas ornament printed with the new cooling fan. Notice the fine point at the tip of the rocket. I couldn't have done this before (or print the steep overhang angles on the fins) without the cooling fan.by elkayem - Prusa i3 and variants
I've been on the hunt for a compact mount for a PLA layer cooling fan and inductive sensor probe that would work with my E3D lite6 hotend. I've seen a lot of solutions where one fan does dual purpose (heat break cooling and layer cooling), but that's not an ideal solution because the heat break fan needs to stay on all the time, while the layer cooling fan should not be on when printing ABS, orby elkayem - Prusa i3 and variants
Quotesonnylowe Updated my Marlin firmware to 1.1.0 RC2...everything seemed to be working fine. But while running a few calibration prints I got a "HEATER FAILED" fault.

QuotePutzer elkayem The picture is wrong. I have the same 8m from Banggood with 2mm pitch. Nothing like the picture shone. They only move 2mm per rev, not 8mm. You must have ordered one with only one start then. However, the banggood ad I forwarded says it has an 8mm lead. Also, looking at the picture inside the brass nut, one can see that unit has four starts. If I do decide to make that chby elkayem - Prusa i3 and variants
QuoteLancelotL Also I have the same question as you about the lead screws. Only thing I can figure is that backlash may be reduced in the lead screws. I agree that backlash reduction would be one advantage, though backlash isn't an issue for the Z axis since it moves only in one direction. (At least for those of us who don't use auto bed leveling.)

Here is an interesting discussion of lead screws vs threaded rods for 3D printers: Accuracy vs Precision and Threaded Rod vs Leadscrews in 3D Printers One pertinant quote from the web site: Quote In general, FFF/FDM printers use relatively infrequent, small, precise movements on the z-axis and consistent, fast movements on the x and y axes. A single start leadscrew with the tightest pitch poby elkayem - Prusa i3 and variants
QuotePutzer elkayem A way to look at it. The rods you refer to at Banggood has a 2mm pitch (2mm travel for one revolution. Common stepper motors have 1.8 degree per step meaning 200 steps per revolution. 200 into 2mm gives you .01 mm per step. Hi Putzer, The banggood lead screws have a 2mm pitch and 4 starts, with 2mm x 4 = 8mm lead. You can see in the picture that the thread angle is prettyby elkayem - Prusa i3 and variants

One more question, since it's a holiday and I have nothing better to do... For those who have migrated to 8mm lead screws rather than the M5 threaded rods (e.g., this from banggood), why did you make that change? I confess, I don't get it. Those lead screws have an 8 mm lead (meaning travels 8 mm for one rotation) as opposed to the M5 threaded rods which have 0.8 mm. That's a 10X reduction inby elkayem - Prusa i3 and variants
Speaking of Z-axis distance... The one thing that really bugs me about this printer is the limited Z axis range. I can get up to about 140 mm, with a bunch of wasted space up on top. The big problem is that the distance between the holes for the M5 threaded rod and M8 smooth rods on the X-end printed mounts do not quite match the hole spacing on the acrylic mounts underneath the Z-axis motors.by elkayem - Prusa i3 and variants
