EDIT: 2/14/18 - This object was non-manifold, and though it never impacted printing for me ,it was always bothering me. I went back into Blender and just took out the non-manifold bits. I also rotated to the proper printing orientation to save everyone a step.

A simple mount for BLTouch (Smart) for the stock CR-10 setup. I've reclaimed pin 31 from the SD card to use for servo control.

I really like your bed leveling knob, Where did you get the files for that.

Thank you very much for this mount! I've got my BLtouch mounted and hooked up to pin 27 (buzzer) on my CR-10. Don't have a CR-10S. For me, it requires

  • enabling Z_SAFE_HOMING, because the sensor's position at X_HOME is outside of the bed
  • disabling the LCD!, because otherwise the sketch is too large to fit with bilinear mesh leveling (by 12.3kB).
    The last point is not a show stopper as I run my printers from OctoPrint, but it certainly isn't nice. Do you guys know if it's possible to run some other LCD code variant with the CR10 display?

I apologize but except the orientation I can't see the differences between the non mainfold and mainfold version (sorry, my fault)...could you explain me?
Thanks and regards

There is no functional difference. There were just several non-manifold edges in the original design which I had made very quickly. Those are just fixed in the manifold version.

Sorry if I missed it but what are the offsets for this mount?

Short video made to configure marlin 1.1.8 on CR10S


Attention if you want to use this change and keep the original switch z do not connect the WHITE AND BLACK cables

Mille grazie Samuele!

To people complaining that this is in Italian, I don't speak Italian either but I was able to understand enough to complete the upgrade. The OP is not an English speaker and may not be comfortable in English. He was kind enough too share his knowledge with the rest of us and for this we should thank him.

I agree with dcperdue, english please. Keep things consistent.

considering this site is English your video means nothing as its NOT IN ENGLISH!

I wouldn't go as far as saying "it means nothing". It does mean something to people who speak a Romanic language. I, for example, do not even speak Italian but I do speak French as a foreign language, which helps me understand what he says in his videos. So for me (and other people like me) his videos are helpful.

I do however agree that an English video would be better as it would be helpful to a lot more people and that the comments linking to the videos should contain a note that makes it obvious that they are in Italian, so that people do not have to find that out the hard way.


where is the configuration in marlin for a home Z in the middle of the bed

thank you

Look for z_safe_home.

thank you very much I still have a problem heating errors happen at 52 ° of the bed

Hi all 3d printer !
Updated my CR-10S S5 to Bltouch and Keenovo Silicone Heater CR-10S S5.
Thermal camera picture over Keenovo bed in zip file.
Bltouch, Wow, 0.001 ~ 0.05mm and works well with Ac bed.
In Bltouch CR-10S S5 Wiring, firmware mm.zip are everything you need if you want to try, except one Bltouch ;-)
Works very good.

In Marlin setup for bltouch, bedsize mm,zip
If you want to try !

Here are the most important changes in Marlin firmware Configuration.h you can do, needed for bltouch as well as set the size of your bed you have. There is much more to focus on but a good start that works, Bjax

Hi, is possible you've updated this to marlin 1.1.8? Thanks in advance

Unfortunately not, I've built a lot and now have E3D Aero printhead and that's a lot that does not match "original". Has not actually entered 1.1.8 to myself. Greetings Björn

If your using the normal sized cr-10s, you'll need to adjust the probe bed boundaries as well as setting the bed and z height to 300,300,400 as Bjax mentioned;

---line 777---(print area adjustment)
// The size of the print bed

define X_BED_SIZE 300

define Y_BED_SIZE 300

// Travel limits (mm) after homing, corresponding to endstop positions.

define X_MIN_POS 0

define Y_MIN_POS 0

define Z_MIN_POS 0



define Z_MAX_POS 400

---line 877---(Probe boundaries)
// Set the boundaries for probing (where the probe can reach).





You'll get a compile error otherwise. Thanks for doing all the hardwork Bjax.

I need massive assistance with this. All is installed and flashed and working... however my offset is off and no matter what I do to measure and set it correctly it just will not set for the middle of the bed. You have yours as 1.25 and I am curious how you got that number. I am at the point of exactly .1 of an offset and it prints decent. I have tried a few different numbers for the offset and some work and some don't, my issue arises when run a bed leveling... the middle is always pushing down in the middle of the bed and the outer edge is damn near perfect. What am I missing and perhaps what could I change? Thanks in advance.

Some values are saved in your printer's eeprom and are not changed when you flash a new firmware. You must reset your eprom if you change offset in configuration.h

Check this Z offset link.

On your LCD display under control, motion, you can set your Z offset as calculated via the linked movie. Remember to save the change. It is also very easy to increase or decrease if necessary.

May be difficult from the beginning to get good value and for me I had to have 6 clamps on the glass bed, if I have 4 st center too low.

Hope this helped a bit, Bjax

Thanks guys! Got mine going yesterday and it made a hell of a difference.

Glad to hear, I have just installed an E3D Aero to improve even more. Recommended! It's starting to be a really good printer.

Comments deleted.

Thanks Bjax. This is great information. I'm going to give it a try this weekend!

Thanks !
To me it works really well.
If you encounter problems, maybe I can help.
Good luck !

did you design this is f360? if so can you post the fusion file so i can modify this to work with a fang? Thanks!

Nope. It was done in Blender (and not very well, I might add)

Thanks for the post, would you have your offsets for this mount for marlin? I'm printing this currently and would like to have a starting point for tuning.

It depends mostly how you set it up (with or without the springs, etc.). You can probably start with 0.0 mm or -1.0 mm offset and work from there.

Can you point me to any instructions on how to configure the firmware and where to connect it?

BLTouch on the stock board is not easy to do. Setting up the firmware just requires enabling BLTouch and setting the right pin. If you want to see how to use Pin 31 (removes SD card) you can see here: https://www.youtube.com/watch?v=ioL-7oEBI1Q&t=778s
