I acquire a bit annoyed at 3D press instructions that tell friend to collection the extruder height by using an undefined item of file as a feeler gauge, due to the fact that the thickness that a piece of paper varies from .002\" (.05mm) to .006\" (.15mm).

You are watching: Thickness of a sheet of paper in mm

I\"ve had some prints that didn\"t adhere, and some the were knocked end in mid-print, and I\"m pretty certain that the extruder height is the an essential factor.

So I desire to usage a stole feeler gauge for reproducibility and also durability: which steel leaf execute I use?

Just how precisely much elevation should one collection for the the extruder-to-plate gap, to express in international measurement units, fairly than in piece of arbitrarily paper?

The firmware presume 0.1mm.

And the item of printer file was used as pretty lot everyone has it, and it\"s an extremely often 0.1mm. Few people have actually steel gauges.

Thanks - I\"m an old car guy - still got a collection of feeler gauges because that \"spark plugs\".

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

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

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

I\"m reasoning of going that route since even through a feeler gauge, I simply can\"t obtain the emotion right. Sometimes the feeler is chop or lose or feel the same. And also any push on the bed can enable the feeler to go under the head and add in compressible blue tape and also I find it really inconsistent.

I like the idea the a dial indicator, but doesn\"t the downward push of the spring in the gauge cause a mis-reading by advertise the bed down?

Hmmm that is a good point. Difficulty is, for this reason does the downward pressure of the feeler gauge so that is tough to recognize the \"feel\" unlike speak a spark plug the is rigid in ~ both points.

the feel is various is friend are also slightly pressing down top top the feeler. I\"ve even seen the gap change from the load of the hex driver the came v the UM1 kit.

I guess if comes under to consistency. If you know that 10.7 centimeter under the push of the gauge functions for the front and 10.5 for the earlier then at the very least you have the right to repeat prints there is no fussing about with the first layer or two.

Are there any gauges through a really light spring pressure?

I understand this is an old article, but using a feeler gauge is a very good idea, together it is a high precision measure up device.

But to accomplish success you must know just how to usage it. It need to not be offered a device to determine the grip or resistance the the hotend advertise on it. A feeler gauge is a smooth metal tool that will not exert much or any resistance under pressure.

The correct way to usage it is to measure if the device \"fit or don\"t fit\" in a gap. Thus, you should slide the tool under the hotend, if that \"slides under\" it way the space is either accurate or come big. So you adjust the space slightly smaller, and shot again, till it does not slide under anymore. Then you earlier out as little as friend can, and also test again, and also repeat this till the feeler gauge slides under.

Now come ensure you have 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 space is 100 microns, you need to select a 105 microns gauge) climate if that does no \"slide under\" it method you have actually not overshot your tolerance, if it does, it method you did and also you need to shot and do a finer adjustment.

Pro tip: To aid you make little adjustments, use one hand come compress the spring the pushes against your adjustment screw. Then you can easily adjust your screw and then permit go with the various other hand to let the plate go back to the readjusted level.

PS. A feeler gauge is a cheap tool. Simply buy that from any kind of motoring gives shop.
