@xiando - I ran the stl through netfabb Studio Basic 4.9 and it's perfect. No errors to fix. @gulf - interesting, I always use relative E, so I selected the '5D relative E' profile for Firmware type. BTW, I always add a bit more info to my gcode labels to tell me which slicer it was produced by, which printer it's for etc. to help me keep them organised. That's why I have "KSS.gcode" as my fileby richgain - Experimental

Looking for some help to resolve my KISSlicer problems because I really want to try it out. I use Repetier Host as my print software but I understand other people use it quite successfully so it must be something I'm doing wrong. Here is a sample of some Gcode generated just now by the latest version of KISSlicer. What I see in Repetier Host when I slice with slic3r: What I see when I sliceby richgain - Experimental
@newperfection - I'm using my new ducted fan on full power but even that didn't seem to stop the bridges from curling up. @gulf - I tried Kisslicer a while back and liked the look of it but the output seemed incompatible with Repetier Host, which I use for all my printing now. I might go back and give it another try to see if that's been sorted out. @richrap - glad it's not just me. Perhaps priby richgain - Competitions
I'm resurrecting this old topic because it was the most relevant thing I could find and it helped me to understand a new problem I experienced yesterday. I just swapped out my old printed X and Y belt pulleys on my Mendel90 for new aluminium ones and expected to see an improvement in print quality. What I saw was quite a serious ripple on the Y axis which hadn't been there before. I discoveredby richgain - General Mendel Topics
I've tried three times so far and had three failures. The first two got knocked loose, the third one stayed stuck on the bed but suffered a massive shift in the X axis, presumably when the nozzle was obstructed by one of the bridges as it curled up. I might give it another go but any suggestions for tweaks to the gcode would be gratefully received. ; generated by Slic3r 0.9.2 on 2012-09-01 at 1by richgain - Competitions
Try repeatedly decreasing the extrusion width by a small fraction until the slicer is confident that it can fit another line of filament in the gap?by richgain - Printing
A bit late for the contest, but I enjoyed making this so thought I'd share it anyway. Printed in yellow PLA from Faberdashery on the Mendel90. A bit of fine stringing still needs cleaning up but mostly quite presentable. ; generated by Slic3r 0.9.1 on 2012-08-22 at 09:36:34 ; layer_height = 0.2 ; perimeters = 1 ; solid_layers = 2 ; fill_density = 0.2 ; perimeter_speed = 30 ; infill_speed = 50 ;by richgain - Competitions
Just in time, here's my effort for this week. My first attempt was pretty awful - just demonstrates the importance of a fan. I didn't have one for the Mendel90. So, I then spent most of the weekend (when I wasn't watching the Olympics) designing prototype fan ducts. Finally, this evening I managed to make one that worked and fitted onto the printer. And the acid test ... I sliced the model usby richgain - Competitions
Hi Rich I'm still trying to print a copy of Tiny Planetary Gears that I can actually assemble! I've used your settings in Slic3r 0.8.4 and also played around with nozzle size and extrusion width a bit but I'm consistently getting holes in the planets that are smaller than the posts they are meant to fit on. Typical values would be 3.0 mm for diameter of posts and 2.7 mm for internal diameter of hby richgain - Competitions
Up and running again now. I bought a new board, chip and steppers from Think3DPrint3D and received them 36 hours later. Excellent service at very reasonable prices. I plan to replace individual components on the fried board and see if I can get that one working again to keep as a spare (or make someone else a printer!)

Have you checked that the thermistor defined in your firmware (configuration.h) matches the thermistor you have in your nozzle heater? It sounds as though you're not getting the correct readings at all.by richgain - Reprappers
OK, I worked out what the problem was. The designer or the object mirror flipped one half and didn't correct the face normals. If you enable ''draw normals' in Blender, you can see that one half has blue lines and the other one doesn't. Using Ctrl-N to reset the normals fixes this. Now the model slices correctly in Slic3r.by richgain - Slic3r
Just tried to user Slic3r 0.8.4 to slice an HDD adapter (4th download on this page) and only one half of the bracket appears. I tried multiple profiles and got the same problem each time. Not sure what's going on here, or it it was a problem in previous versions. richgainby richgain - Slic3r
The weekend started out well with some successful printing at low layer heights with my new ABS. Then after completing 3 out of the 4 prints I was working on, the PCB Mk2 Heatbed suddenly wouldn't come on any more. A quick inspection of the electronics revealed the problem. My fault completely.

Well, it's judging time and I must say I've been very impressed by the quality, if not the quantity, of entries this week. So firstly, my apologies if puzzles don't float your boat, or the longer print times were off-putting. There's always next week! Well done for having a go at it, Josh, and for getting a good fit on the pieces and some nice sharp corners. Rich gave us the beautiful rainbow veby richgain - Competitions

Very nice set of photos, Rich. I really like the rainbow effect and the fit of the sharp angle is looking pretty good too. If anyone else fancies having a go at printing this (don't be put off by the stiff competition - you could get useful feedback on your prints) I would really value photos that clearly show the fit of the sharp point to help me with judging the result.

Great start! That sets the bar pretty high. Whenever I try to print at 0.1 layer height through a 0.3 nozzle at anything less than 50% infill the filled section eventually degenerates into a spiky mess. What's the secret?by richgain - Competitions
Mike has commented that he was unsure how accurate his boolean intersections were so I have had a go myself using Blender to position the cube pieces and the sphere perfectly. Note that I have also scaled these pieces up by 150% so there is no longer any need to do that in the slicing software. I also removed the bevel which I thought was unnecessary. In theory, these pieces should have a marginaby richgain - Competitions
The Mendel90 is going very well and I love it. I'm just waiting on some more filament to give me more choice of colours. Definitely recommended as a good solid machine though. I've applied for a table at the Manchester Mini-Maker Faire in July and, if we get one, nophead and I will be demonstrating Mendel90s and the Huxley with lots of live printing.by richgain - Competitions
Happy Father's Day to all the geeky dads out there.

I finally got around to finding some time for my first competition entry after work today. Nice surprise to find a new version of Slic3r came out yesterday so this was sliced with v0.8.3.

Thanks all, for your helpful advice. I did finally succeed in getting almost flat pieces at the fourth attempt. You have rightly pointed out, nophead, that the motors are decelerating and accelerating already. I suppose I was thinking about varying the rate of deceleration and acceleration - is that the jerk factor? I'm curious to know why printing more slowly causes less warping.

Now onto my fourth attempt, and finally making some progress. For the third attempt I tried slowing the print speed down to 24 mm/s, used ABS juice and turned the heated bed down to 120C first layer, 100C the rest, and it was much worse. All the pieces warped and came loose very easily when I aborted. Now it's running at 16 mm/s with 120C first layer and 110C thereafter. Painfully slow to print bby richgain - General
