why YOU should buy a TOOL LENGTH SENSOR !

[@InheritanceMachining]

And here I am taking 7:45 to change and indicate a single tool on the manual mill 😂 Nice vid as always, man

[@ChristophLehner]

To be fair, you have that satisfying sound from the impact wrench 😂

[@crabsshed]

Thanks for the video. I got to revisit mine and finally set it up properly and mainly get used to using it. Got one installed and it has been sitting on the machine for over two months. Just tried it once or twice. This proves I could have saved a lot of time already...

[@yamlcase230]

It's not just about saving time, it's also about eliminating potential for human error. One screw-up and you gotta scrap the workpiece and start over

[@fierceflyer5]

Great video, thanks for testing this.

[@josephjones4293]

Thanks for the tips… i would love an indepth video on actually setting it all up. I just finished dialing in my servos… tonight im going to mount the spindle and setup the vfd.

[@ChristophLehner]

I've added a section about probing/tool length sensor to the printNC wiki, the link is in the description

[@sailthehighseas]

Nice! I have the same one, now I'm motivated to wire it up and start using it. Unfortunately I'm running Mach4, too bad their forum isn't as helpful. Also two great tips on Fusion that I didn't know yet, thanks!

[@ArcAiN6]

neat... just a slight bit of very important information you left out.. 1) Is it NO or NC? 2) What power levels does it function at? 5v? 12v, 24v? 48v?? 3) How many leads are involved? 2? 4? 6? 8? 4) How is it wired to your machine? are you using a breakout board? usb? parallel? something special?? All of this info is required if you're going to tell someone "Hey go buy this"

[@StemmProductions]

Man you are on a roll of uploads! Love that :D nice video as always, I will get one aswell but firstly I need to build the cnc. Wish me luck guys ^^

[@MrDe0]

Good Luck😁

[@StemmProductions]

@@MrDe0 thanks man :D

Haven’t even watched the video yet, but if you’ve got this thing figured out you are my hero! Mine in LinuxCNC has been giving me nothing but problems. Whatever they use for the top disk material is hard. I've smashed an 8mm endmill into it (because I programmed it going the wrong way in a G0 move :D) and it didn't even make much of a dent

[@ChristophLehner]

It took me.2 weeks fiddeling to get this thing working 😅 The topcover must be made out of carbide, mine came loose so i had to glue it back in, and this disk is really heavy Yeah wiring the overtravel switch should be mandatory, i also broke mine, doing a g0 x0 y0 z0...

[@BryanHoward]

@@ChristophLehner Same. Every single person that has used this very style of tool height setting has said that the puck has come out during shipping. I smashed mine even when testing out the over-travel switch because they don’t give you any extra travel for your machine to come to a stop. The Z-max G28 thing is likely why I couldn’t get it working reliably in LinuxCNC so I’ll have to visit that again.

[@CunningLinguist01]

Another awesome video! More print NC videos!

[@MrScary-zu1vc]

What's the different Normal Open and Normal Cloded ?

[@miniwinisbastelbude]

you´re welcome... nice that it´s working... :)

[@GeorgeZaharia]

u can calculate the tool length if u have good software, u give it a probing of the bottom part where the toll enters... and then u just probe the tool ... and the difference should be ur tool lenght... is not so much different than probing with clamps on a metal for Z positioning...

[@gold-junge91]

If you try with wet paper and rotating spindle you get pretty good accuracy.

[@ChristophLehner]

With wet paper?

[@gold-junge91]

@@ChristophLehner yes trust me I learn this from cnc teacher in my training as Industrial mechanican, paper have round 0,1mm thickness but wet you get like 0.05mm and If you put the wet paper on a surface from your part that you want to cnc then travel to the paper and get as close as possible and a little bit more u see the paper fly away and u can press zero 😁 try it :-) if not talk back to me I try to find a video from my Trainee time. (Of course I have to turn on your spindle but only 100-500rpm)

[@gold-junge91]

@@ChristophLehner i have a machine a my cnc parts in my training like this 🤣😅and get normal trainee time in Germany 3 1/2 years but i get in 28 month’s done 😅

[@ChristophLehner]

@@gold-junge91 thanks! Sounds like a great tip👌

[@gold-junge91]

​@@ChristophLehner try it and tell me how your expierence are :-D

[@xyzspec82]

I want one! 🤓

[@mastermoarman]

Maybe mount the tls in a hole so it's top is more even with the table top? That way you have less to worry about running into the side with longer bits?

[@ChristophLehner]

That's quite a neat idea 👌

[@mastermoarman]

@@ChristophLehner and if your rally fancy you could have it retractable beneath a trap door lol

[@catexis]

@@mastermoarman I know you’re kidding but man a retractable tool would be a repeatability nightmare!

[@mastermoarman]

@@catexis being serious. Have a kinematic coupler mounted to the bottom of the table that has a mating coupler on the tool height sensor. That way it stops and orientation each time

[@oppugnator]

wondering how many start ups are saving the money for a CTO because of your videos 🤷‍♂️

[@3sotErik]

Can I add this function to an Ender with Klipper, using an unused Z endstop?

[@ChristophLehner]

this is for a cnc :D

[@3sotErik]

@@ChristophLehner No, I get that but I also want this for Klipper. I have modified my gantry endstop to extend past my bed & want to move/modify the normal z endstop for auto z offset when I change nozzles.

[@christianmontagx8461]

They call him "Shove-the-toolhead-into-something" 😂

[@Kosh42EFG]

Damn it. You're going to cost me money. Got an Ali affiliate link for the one you use?

[@Kosh42EFG]

Ignore me. It's in the description.

[@ChristophLehner]

Tbf, they are not that expensive 😅

[@andreashabijan2514]

Moin, es gibt bei Ebay gebrauchte Lasergabeln mit 80mm Schenkelabstand für um die 20 Euro. Die sind extrem genau. Industriestandard mit IP67, meist laufen die zwischen 18 bis 32V. Ich wollte mir auch erst was mechanisches kaufen, dann bin ich über die Lasergabelmethode gestolpert.

[@ChristophLehner]

Was ist eine lasergabel? Hör ich zum ersten mal 😅

[@BuildItAnyway]

@@ChristophLehner u shaped thing with laser sender and receiver. You would use this to measure the tool length. Due to using the laser it is very repeatable. Although I doubt it will change much for your application as steppers with microstepping themselves are not very accurate. In other words this is probably good enough.

[@BuildItAnyway]

Do you have a link to these in ebay?

[@jtcmlt1]

@@ChristophLehner those are optoelectronic sensors. They are widely used for packaging and other applications where accurate count is needed... I think 🤔
