I get a little annoyed in ~ 3D printer instructions that tell you to collection the extruder elevation by making use of an undefined piece of record as a feeler gauge, because the thickness the a piece of document varies indigenous .002" (.05mm) to .006" (.15mm).

You are watching: Thickness of a piece of paper

I"ve had some prints the didn"t adhere, and also some that were knocked end in mid-print, and also I"m pretty sure that the extruder elevation is the crucial factor.

So I want to use a stole feeler gauge because that reproducibility and also durability: which stole leaf carry out I use?

Just how specifically much elevation should one set for the the extruder-to-plate gap, expressed in worldwide measurement units, fairly than in piece of arbitrary paper?

The firmware presume 0.1mm.

And the piece of printer record was used as pretty lot everyone has it, and also it"s really often 0.1mm. Couple of people have steel gauges.

Thanks - I"m an old automobile guy - still obtained a collection of feeler gauges because that "spark plugs".

.004" (.1mm) is what i had involved by trial and also error.

I"d bet that if friend measured 100 brand of "standard" printer paper, the median thickness would be close to .075mm, and with fairly a spread out of values. File manufacture isn"t that very closely controlled a process.

If you space an old auto guy and have a dial indicator, there is a dial indictor holder that allows you to location the indicator into the head.

I"m thinking of going that route due to the fact that even v a feeler gauge, I simply can"t get the emotion right. Periodically the feeler is tight or shed or feels the same. And any push on the bed can permit the feeler to walk under the head and add in compressible blue tape and I find it very inconsistent.

I like the idea the a dial indicator, however doesn"t the downward push of the feather in the gauge reason a mis-reading by advertise the bed down?

Hmmm that is a good point. Trouble is, so does the downward press of the feeler gauge so it is hard to understand the "feel" unlike speak a spark plug the is rigid in ~ both points.

the feeling is various is friend are even slightly pressing down top top the feeler. I"ve also seen the gap adjust from the weight of the hex driver the came with the UM1 kit.

I guess if comes under to consistency. If you understand that 10.7 centimeter under the press of the gauge works for the front and also 10.5 for the earlier then at the very least you deserve to repeat prints without fussing about with the first layer or two.

Are there any type of gauges through a an extremely light spring pressure?

I know this is one old article, yet using a feeler gauge is a very an excellent idea, as it is a high precision measure up device.

But to attain success you must know just how to usage it. It must not be provided a tool to recognize the fixed or resistance that the hotend pushing on it. A feeler gauge is a smooth metal tool that will certainly not exert lot or any kind of resistance under pressure.

The correct method to use it is to measure if the tool "fit or don"t fit" in a gap. Thus, you need to slide the device under the hotend, if the "slides under" it method the space is either specific or come big. Therefore you readjust the void slightly smaller, and try again, till it does no slide under anymore. Then you ago out as small as friend can, and test again, and repeat this till the feeler gauge slides under.

Now to ensure you need to backed the hotend out much more than your yongin you require to pick a slightly larger feeler gauge (if your yongin is 5% and your void is 100 microns, you require to select a 105 microns gauge) climate if that does not "slide under" it means you have actually not overshot your tolerance, if it does, it means you did and also you require to try and make a finer adjustment.

Pro tip: To assist you make small adjustments, use one hand come compress the spring the pushes against your mediate screw. Then you deserve to easily readjust your screw and also then allow go with the various other hand come let the plate return to the readjusted level.

PS. A feeler gauge is a cheap tool. Simply buy it from any motoring supplies shop.
