Tighten your belt tension on all axes if that's not the case.Ĥ) Retighten all screws on your unit including beneath the heatbed belt mount (which can come off) if prints look wonky.ĥ) Calibrate your E step throughput (guide here > Ħ) Adjust your retraction rate if prints look offħ) Level your bed. In the 1.75mm vs 1.70mm example above, you would want to set the flow multiplier to 1.75/1.70 = 1.03 (or 103 depending on how your slicer represents the number).ĭepending on the capabilities of your printer, you may also be able to adjust the flow on the fly in the LCD or via a USB connection to the printer.ġ) Add Z-axis stabilisers to your setup >Ģ) Add rubber grommets/cut rubber piping to the corners of your heatbed to reduce bed judderģ) Check if your prints are proper size with a caliper. To figure out what to set it at in the over or undersized filament case, the easiest thing to do is divide your desired filament size (1.75 or 3mm) by whatever you measured your filament using digital calipers. In Slic3r, it's called "Extrusion multiplier" and is on the FIlament tab, other slicers will likely call it something similar. Cura 2.3 calls it "Flow" and is a setting that's hidden by default. Depending on which slicer you're using, it is either represented as a floating point integer (1.00) or a percent (100).
The two main uses are to adjust the flow for filament that isn't to spec (e.g., if you have 1.75mm filament that's actually 1.70mm, you'd want to set the flow to be higher since it's undersized) and to assist with fine-tuning your extruder's steps/mm. The extrusion flow multiplier basically increases or decreases the amount of filament fed into your hot end. I think Craftware has the ability to send to the printer, but I've never used that feature because I set up an OctoPrint server to manage my printer via a web browser.

It's got all the bells and whisltes of Slic3r, plus the ability to set your own supports instead of just where the program thinks they should be. I've since switched to using Craftware ( ) with good results. If I recall correctly, v1.2.7 worked much better, but is a little more flaky and crashes periodically. It's documented as fixed in their bug tracker, but there hasn't been a new release including the fix yet. I was running a 0.6mm nozzle at one point, and the Slic3r gcode was almost unusable. Lastly, I found out the hard way that Slic3r v1.2.9 has a very serious extrusion calculation bug, especially with odd-sized nozzles. I have an E3D V6 and print on a sheet of PEI, so unless you use the same filament as me and have the same setup, your temps will almost certainly differ. The Green likes it a little hotter at 210C-215C and 70C bed, otherwise it doesn't stick to the bed. The blue goes down and I get good inter-layer and bed adhesion with 200C (70C bed). For example, I have a blue and a green PLA by the same manufacturer. I feel it gives me a better surface finish and still keeps the job moving at a reasonable pace.Īfter that, start playing with temps within the range recommended by your filament manufacturer, running the same job as a benchmark for each one.

I also like to slow down on the first layer, outer perimeters and top layer (like 30mm/s) and run the inner perimeters and infill at full speed (60mm/s). You should be able to lay down a first layer that's smooth (no bumps, no dips), and it stays that way all the way to the top. You'll also have problems with parts not fitting together, screw holes that are too tight and whatnot.īetween those two alone, you'll be amazed at the difference in your prints. It'll also mushroom out on the first couple of layers before adjusting itself once it reaches the non-solid infill areas, and then can cause a rough top again. If you're overextruding, especially on the first layer, the nozzle will plow through the filament already laid down, causing a rough surface. The exact terminology depends on your slicing software.
I just use paper (post it notes, actually) as a feeler gauge - 2 sheets grabs between the nozzle and bed, 1 sheet moves almost freely but you can feel just a tiny bit of grab.Ģ) Perfect your extrusion flow multiplier/percentage.
