Print not sticking to bed... bluetape

Print not sticking to bed... bluetape I'm trying to get my first print to stick to my bed and I'm not having much luck... I'm using Slic3r and have gone through the program and I believe everything is set accordingly for my CoreXY setup. I'm attempting to print Hatchbox PLA at 190C on bluetape on an aluminum non-heated bed (at the moment) as I think is what is recommended. I've successfully set the extruder feed rate, hot end temperature and bed temperature for my machine. From what I can see from the video I've attached it looks as though the extruder is not feeding enough material so that got me thinking about some additional setup questions for Slic3r. [url=https://youtu.be/zukkSU91QMI]1st print failure[/url] Since I didn't add any information about my machines speed in Slic3r, how does it know how fast it can print? and how does it know how fast to extrude material? This is a portion of the gcode I was attempting to print, nothing more than a flat disk. [code] ; generated by Slic3r 1.2.9 on 2017-12-19 at 10:31:27 ; external perimeters extrusion width = 0.40mm ; perimeters extrusion width = 0.48mm ; infill extrusion width = 0.48mm ; solid infill extrusion width = 0.48mm ; top infill extrusion width = 0.48mm M107 M104 S195 ; set temperature ;G28 ; home all axes G1 Z5 F500 ; lift nozzle M109 S195 ; wait for temperature to be reached G21 ; set units to millimeters G90 ; use absolute coordinates M82 ; use absolute distances for extrusion G92 E0 G1 Z0.300 F7800.000 G1 E-2.00000 F2400.00000 G92 E0 G1 X121.523 Y121.522 F7800.000 G1 E2.00000 F2400.00000 G1 X123.046 Y120.071 E2.08151 F1800.000 G1 X124.761 Y118.592 E2.16925 G1 X126.546 Y117.207 E2.25676 G1 X128.392 Y115.921 E2.34394 G1 X130.292 Y114.737 E2.43066 G1 X132.237 Y113.659 E2.51681 G1 X134.218 Y112.688 E2.60231 G1 X136.519 Y111.710 E2.69917 ...

or change any hardware
you need to check if the nozzle hight is still good.
Check multiple times, after a new zero. (paper calibration)
Don't change any thing between the multiple zeroings, It is possible that the zero sensor doesn't repeat accurate engough]]> amigob Printing Wed, 27 Dec 2017 04:35:51 -0500 https://reprap.org/forum/read.php?262,801544,802447#msg-802447 Re: Print not sticking to bed... bluetape https://reprap.org/forum/read.php?262,801544,802447#msg-802447 I even printed on a sheet of inkjet printer paper taped to the bed.

I have the best luck printing on the Vinyl Application Paper Tape. Maybe if I experimented with bed temperatures I could get my Build surface to stick better, but why this works for me.
And maybe the Build surfaces I purchased were counterfeit. I have no way on knowing. They just did not work well.
I even purchased a different build surface they are still unused in the packages.]]> Roberts_Clif Printing Tue, 26 Dec 2017 20:53:15 -0500 https://reprap.org/forum/read.php?262,801544,802446#msg-802446 Re: Print not sticking to bed... bluetape https://reprap.org/forum/read.php?262,801544,802446#msg-802446
Does just printing on another material cause better sticking, blue tape just isn’t good for adhesion???

It sticks great and can cover the bed in one pass, as is come is varying widths to 4 foot. I use the 12" wide 300 foot length tape as my bed is 8 3/4 inches wide. Cost about 12 cents to cover the bed and last about a week².
About 1/2 roll left of purchased in October 2016 stock, hoping it last until October thereby making 2 year on one roll of tape.

I have never used Blue Tape. And have barely got my expensive build surface to work once in a blue moon.
I Start my Prints from 30 - 56 percent speed (30% lots of curves and small) (56% medium to large in size)from 192-202C hot-end temp with a bed temp of 40 - 56 C.

1. weeded to remove all excess vinyl material that will not be part of the finished product.
2. As it is paper it can tear when removing models, divide the bed into four quadrants when printing smaller parts it will last even longer. when you get the nozzle height dialed in it will last longer.]]> Roberts_Clif Printing Tue, 26 Dec 2017 19:45:37 -0500 https://reprap.org/forum/read.php?262,801544,802442#msg-802442 Re: Print not sticking to bed... bluetape https://reprap.org/forum/read.php?262,801544,802442#msg-802442
X and Y are driven by a belt as this is a CoreXY build however my Z axis does contain 2 couplers.

I'm assuming that the calibration cube is labeled as to which axis is causing the problem? If there are problems on the X side of the cube I should be looking at the X axis, correct...

To solve remove the lead screws from there coupler Wrap one turn of electrician tape on The bottom of the lead screw and return to the Coupler. Extruding excess tape can be cut and removed from the lead screw. (only one wrap will fit)
When raising or lowering the Z axis if you notice the coupler wobbling then this is definitely the fix.

Not sticking to Blue Tape
This appears that again you have allowed the Z-Axis to start the print .1mm too high. Lower the Z-Axis .1mm
Look at IMG_2075.jpg it looks like the Skirt is completely round, the first layer should be closer too looking like a little rectangle flat on top and bottom with slightly rounded outer edges.]]> Roberts_Clif Printing Tue, 26 Dec 2017 18:45:05 -0500 https://reprap.org/forum/read.php?262,801544,802439#msg-802439 Re: Print not sticking to bed... bluetape https://reprap.org/forum/read.php?262,801544,802439#msg-802439

Print anothe cube scaled up 2 times. Then check if the oversize is still 0.4mm, it's e-steps.
If the oversize grows with the scale factor it's x/y steps.]]> o_lampe Printing Fri, 22 Dec 2017 02:48:21 -0500 https://reprap.org/forum/read.php?262,801544,801920#msg-801920 Re: Print not sticking to bed... bluetape https://reprap.org/forum/read.php?262,801544,801920#msg-801920

the bottom picture shows a filament diameter of 3 mm, is this what you are using ? most fillaments are 1.75mm. these days.
From the video, i see no filament being extruded during the print, this could be the above menssioned setting or nozzle being too close to the bed,restricting the flow.
Also i would set the 1st layer temperature a bit higher(210-220) to help 1st layer bed adhesion.
Print speed settings are set in the 1st picture,under speed, might be a tad fast atm.

Good catch on the setting obewan it was incorrectly set, so I went ahead and made that change as well as upping the temperatures a little, 205 for the first layer and 200 for the remaining.

I was able to print another test cube with some pretty good results today but dimensionally its not correct and there are some artifacts in the print that I'm not sure what I would call in order to diagnose.

So from a dimensional standpoint is that adjusted in the steps per mm on the steppers?

Even the 1st layer infil doesn't touch the perimeters.
I can't remember where the 1st layer multiplier is but its not the generic multiplier you have set to 1.5. I think its called 1st layer width but you put in 150% (as percent not mm)
There is definately something wrong with your settings if you have 3mm filament and a 1.5 multiplier and its still under extruding.
Insidently i would bump the Z offset up to -0.2 if you set it with paper.
Can you confirm your nozle size and make sure its the same as specified in Slicer.
I wasn't clear what the answer was on the 3mm filament. Is it 3mm ? You have to have the correct size in slicer and that shows 3mm.
No you can't get the nozle to negative positions. That is why I said when you level the bed the gap must be less than the 1st layer height. The the Z offset will be subtracted from the layer height and the remainder will be the Z value for the 1st layer and must be posetive. For example Gap (Z offset) -0.25, 1st layer height 0.2. Gcode Z value is 0.2 - 0.25 = -0.05. This is not achievable as the nozle will be restircted by the end stop at Z = 0 and produce an under extruded 1st layer height of 0.3. This error of 0.5 will be carried into the 2nd layer which will have extra "squish" so may appear to be overextruded. 3rd layer will be OK but may have some effects from the previouse layer being over extruded.]]> MCcarman Printing Thu, 21 Dec 2017 08:47:02 -0500 https://reprap.org/forum/read.php?262,801544,801773#msg-801773 Re: Print not sticking to bed... bluetape https://reprap.org/forum/read.php?262,801544,801773#msg-801773 ampapa Printing Wed, 20 Dec 2017 21:57:35 -0500 https://reprap.org/forum/read.php?262,801544,801772#msg-801772 Re: Print not sticking to bed... bluetape https://reprap.org/forum/read.php?262,801544,801772#msg-801772 [www.thingiverse.com]

Measuring the cube dimensions shows that its not exactly 20mmx20mmx20mm so I assume that means that the stepper calculations are not correct or can that also be caused by under extrusion?

I'm not certain what he prints are telling me except that there is work to be done.

Are there good references for how to determine what the problems are and how to tweak the settings to accommodate for the problems? Slic3r has a ton of settings...

I'm not certain if the Z Offset was the key or if the extrusion multiplier did the trick.. it was one, maybe both of them though.

Lots of gaps in that 3D cube..

So I believe now printing test/rise/repeat comes into play as far as setting up the machine for good repeatable prints.

I'm noticing 2 things right off..
- the perimeter is not printing well just when the print is getting started (trying to increase initial temps)
- when infilling the cube it looked like it was having problems with speed and getting the layers to stick

I bumped the "first" layer temp to 210 as suggested and will give that a try.

I also think I found the speed setting page.

Does the extruder click as it is trying to print that first layer?

No clicking form the extruder. I'm still thinking somehow there isn't enough material being pushed.. trying to run some tests.

Also worth increasing the 1st layer extrusion multiplier to 150% to generate pressure and even out errors.

Im guessing your 1st layer is set to 0.3 so currently you will be printing in fresh air.
The bed to nozle gap you set (with paper etc) must be less than the 1st layer height if you have physical end stops.

If you have a 0.4 nozle the external perimeter width of 0.4 (same as nozle diameter) may be significant when reviewing quality later.]]> MCcarman Printing Wed, 20 Dec 2017 08:02:37 -0500 https://reprap.org/forum/read.php?262,801544,801607#msg-801607 Re: Print not sticking to bed... bluetape https://reprap.org/forum/read.php?262,801544,801607#msg-801607

It is in the Slic3r Configuration

TAB
"Printer Settings" under "Extruder 1" option...Retraction area... It is called "Lift Z:" This only lifts during a Retraction.

Would Think you may be able to use

If the extruder chews a divot into the filament it won't be able to extrude any more. Chewing a divot means that the pinch roller pressure is too light- crank it down so the drive gear teeth bite deeply into the filament. The extruder should skip steps and should never carve a divot into the filament.]]> the_digital_dentist Printing Tue, 19 Dec 2017 15:59:12 -0500
