As James said, definitely do calibrate. You should also calibrate your retraction. Here are other Slic3r Tutorials and videos. Quotejimmyvinnie infill was only 20% and appeared to be extremely sporadic The sparse infill in Slic3r is very much like bridging. It doesn't touch except at the ends and where it crosses other infill. As a result if the extrusion width is not set wide enough itby Paul Wanamaker - Printing
Hi Delco, I just wanted to mention that some have had problems with the Smoothie clones, aka Azteeg due to the DRV8825 drivers on the Azteeg. The DRV8825 drivers can cause missed microsteps and should be avoided.by Paul Wanamaker - General
QuoteJamesK OK, that makes sense. I was confusing the two issues of bad infill and poor bridging. Actually, they are directly related in a couple of ways. - Sparse infill with Slicer - like Rectilinear - has layers that only touch where they cross - and this is a form of bridging - but worse. If done too fast, or too narrow it will break, especially when crossing other strands. The same thing hby Paul Wanamaker - Printing
Slicer outputs bridging at nozzle diameter, and uses layer height at the bridge location to accommodate that specific nozzle height, with the lines at or just over nozzle width apart. So changing the layer height should not matter. If the lines are too thin they will snap, too fat and they sag. You could try a LOT bigger flow ratio to see if it will bridge without breaking. The first bridgeby Paul Wanamaker - Printing

You may want to use DC42's least squares calculator here. It may help you determine if some of your measurements are off.by Paul Wanamaker - Delta Machines

Hi Chngyian, When you attach STLs please first slice with Output Options, Verbose Gcode turned on. You may have to link them to Dropbox etc if they are over 514k. I can view the segment details in my gcode debugger.by Paul Wanamaker - Printing
Sungod3k, I've started looking at the files. Temperatures appear to be the same. What Cura version are you using? The Cura gcode does not indicate the version inside. The Repeteir gcode indicates it is using Cura_SteamEngine 15.01 I will make some changes to my gcode post-processor/analyzer/visualizer to recognize the way Cura identifies it's different segment types (it's recognizing Slic3rby Paul Wanamaker - General

James, That's a good example of what I'd call a stall. Imagine that the filament is melting into an cone like this (my drawing, not exactly to scale): If the hot end is cooler, or the extrusion is faster what will happen? I believe the un-melted point will get closer and closer to the orifice until a fast extrude causes it to temporarily plug the opening. I did quite a bit of testing forby Paul Wanamaker - Printing
Sorry, I've been sick. Take a look at this excellent guide. It's a complete build a Prusi I3 from scratch blog. This page has information on adjusting the drivers. You might want to read through all of it, it talks about everything I can think of, including endstops, firmware, calibration.by Paul Wanamaker - Printing

I haven't released the software yet. Part of that software is for gcode post processing for things like pressure compensation, first segment acceleration, coast while retracting, angular hops - things that I want to prove, so they can be part of Slic3r. So as part of that I'm also working on a great many test generators for guided calibration - since there are some complex and interacting elemby Paul Wanamaker - Printing

Hi Goldiee Can you show a photos of that last one at different angles? What I'm curious about is which axis the offset is happening on, Y axis, X axis also? What kind of stepper drivers do you have - DRV8825 or a4988? It's interesting that it starts happening after a certain time. That makes me think of a thermal cause. Do you have a fan on the drivers? It could also be mechanical - somethingby Paul Wanamaker - Printing
Hi Zwicker I just ran across a guide that has a lot of info for Prusa I3's. Even though it isn't your exact model it does have a lot of details that could help. See Constructing a 3D Printer .by Paul Wanamaker - Reprappers
Dim, I'm still under the impression that we are diagnosing an extrusion stall. The only way I know of going about this is by process of elimination. I looked at the firmware settings. The only extruder related item that could be tweaked is the acceleration - you could try lowering that by 25% and see if that clears it up. I don't think that's it, but could be...

I blew up one of the photos and took a look, posted here so others can comment. I see two kinds of artifacts: - Circled in blue are little craters or skips, these appear all over. - Circled in red look like short segments of over extrusion. These seem to occur more around corners. Does this agree with what you are seeing first hand? 1) The craters could have at least a couple of causes aby Paul Wanamaker - Delta Machines

QuoteDC42 If that happens then I think your drivers are faulty, or the circuit that generates the voltage reference for them is badly designed. Increasing the supply voltage should make no perceptible difference to how hot the motors run, and only a small difference to how hot the drivers run. You are correct, thank you.

One clue is how the problem is increasing with height, where a slight delay happens due to layer change, and also that it doesn't happen with an infilled shape. It's a very small object, I think it's just overheating there. You've got lots of options to test that - multiply the object, make a larger object of same wall thickness, etc. Best to test that first.by Paul Wanamaker - Delta Machines
YES, I recommend using Repetier. I will cost you nothing but a little time. Since you know all your delta parameters, their web page wizzard will make it easy to input them, and it will create a customized setup. Then just compile it and go. Use the quad stepping feature too. I have a Smoothieboard so I can not test with marlin. You may be able to have someone test this through the Marlin gitby Paul Wanamaker - Slic3r
Yes, you can use a higher current power supply, and that is in fact the best way to go. A power supply is rated in Watts which is Volts * Amps. If you had an actual constant load of 1000w, and used a 1000w power supply, then it would always be running at 100% capacity - it's components would run hot and it would fail earlier. Sor for a 1000w load you would want a 1400w power supply, etc. Therby Paul Wanamaker - General
Is just the same way you can plug-in different wattage lightbulbs into a wall socket, say A one watt bulb or 100 W bulb. The 1W bulb has much higher resistance so it draws less current. So each type of thing that is plugged into the board is using only as much current as it needs and was designed for. There are some components on the board for example the processor chip that require a lower volby Paul Wanamaker - General
