Project give-away
LGX on CR-6SE
With this post we will teach you how to upgrade the Creality CR-6 SE with a Bondtech LGX, from the stock bowden setup to a shortbowden extruder setup.
This setup uses the stock hotend. We are also preparing parts that will allow to use other hotends like Copperhead and Mosquito.
Bondtech is sharing the STEP and STL models of the required plastic parts. Check below for links to download them.
To install this upgrade you need to 3D print the plastic parts and buy the Bondtech products below.
We ask you to source PTFE tube, but Capricorn will be a better option.
For a more long lasting solution consider upgrade the hotend to an all-metal.
POST PUBLISHING UPDATE
This post tells you how to install a
LGX
extruder on the CR-6 SE, but check also what Michael Bourque did. Below find links to his related projects with very interesting solutions.
5. On the video we finish the setup by adjusting the Vref from 1.36 (stock value on our printer) to 0.8. It is recommended to use from 0.4 to 0.8. Lower the Vref if stepper motor is too hot to touch. Use a Multimeter to perform the procedure. Remember to read using V
DC
and to use a scale that may show you at least 2 decimal places.

Do you tought about create an adapter like the DDX V3 of the LGX for CR-10S Pro v2, i want one but now i have saw the LGX i would prefer go to this model.
Thanks for the response.

Hi Oliver,
We understand why you prefer the LGX. It has brought many new great features and it is a great extruder.
Until the end of the year, and because we have so many other projects running, we are not planning on creating a LGX based DDX.
Until then, in our opinion, if you compare using a custom LGX setup against using the current BMG based DDX v3, we believe the DDX v3 is a better option.
Thank you for your interest in our content.

How about making the same mount to fit the ender 6 also. So many of us in the ender 6 Facebook group have an LGX but there is no mount out there for us to mount this to our ender 6. It would mean a great deal to the ender 6 community if one was created for the Eder 6 to have the LGX mounted to it. Thanks
Nuno Santiago
says:
Hi Peter,
We assigned many resources to create a good solution for the Ender-6.
Our work was focused on changing the DDX to fit it. We finally have it working with the DDX v3.
For the time being, and because we have so many other projects running, we are not planning on creating a parallel solution based on the LGX.
We supply in this post the STEP files of all the parts used.
To install a LGX on the Ender-6 the way we did here, we hope someone can come forward and make the necessary adjustments to our parts.
Thank you for your interest in our content.

As soon as that’s available, I’m in. It would be great to use the high-flow mosquito and LGX with the CR-6 SE.

We will release this week (until 19th June 2021) an adapter to use Mosquito hotends on this solution. Copperhead is still under study.
Thank you for your interest in our solutions : )

Just confirming if I am about to purchase the LGX and mosquito, will you be supplying the hardware bracket or will they be printed by the user ? Just trying to figure out if I hold off and purchase everything as a complete kit or can I purchase the LGX and Mosquito Hotend now and print the bracket when released……awesome work

Hi Nuno,
Just a little bit of feedback on the LGX on the CR6. I am using the printed files and I struggled to get good prints that would hold up well over time. I think if you provided parts that could be purchased this would be far better. I think giving people the option is also good. I think you need to have both options.

I would also be very interested in a complete solution. I ordered the mosquito hot end and attempted to print the specified parts but I guess my tolerances just aren’t there. They didn’t work. So the mosquito is sitting in my parts Drawer until such time as an factory solution is produced. Hope that is soon as I am very pleased with the mosquito running on my CR-10 S4
Nuno Santiago
says:
Hi Loki,
We were not planning on making the Mosquito adapter available to purchase.
We can eventually make that part for you alone.
What we are doing is developing a full and special upgrade kit for the CR-6 SE and Max that uses our LGX Lite.
It will also allow to use the Mosquito hotend.

Hi Nuno,
Is the work on that still going ok? Looks like the 19th has passed us by. Looking forward to it.
Thanks
Sorry for so much delay.
The Mosquito Adapter file is available already at the bottom of the post.
Thank you.

Hi Roger,
As you know with the BTT SKR for CR-6 mainboard you don’t need the multimeter neither to turn potentiometers on the PCB to adjust the stepper drivers’ current. It uses TMC2209 stepper drivers, same as stock, but you may control their current on the firmware using mA.
On the LGX we recommend to use a current between 400 and 800 mA.
The
2 main rules on setting the current on the LGX
are:
Lower the current if the stepper motor is too hot too touch.
Raise the current if the extruder skips steps.
Final note:
We saw already examples coming from customers using boards that have these UART-controlled stepper drivers and use the LGX with a 100 mA setting. So
follow the rules and use our recommended values only as a starting point
.

Hi Nuno,
Is there any update on when the Mosquito adapter/mounting solution will be released. I have held off from buying as Mosquito until you release the mount, either for purchase as a printed part or to download and print. Please could you provide an update on expected release date. I understand sometimes things take longer than expected and that is fine, but just a rough update would be really appreciated.
Many thanks for the great work!!
Hi Lee,
We continue delayed.
I was not aware when I last wrote you but my colleague in charge of that project started a 4 weeks vacation.
Meanwhile I will also have my Summer vacation.
We have to delay news until September.
Lee Wilkinson
says:
Hi Nuno,
Waited until September as you advised. Is there any update please?
Thanks
We couldn’t get Cura to deliver good results with this setup.
We now use Prusa Slicer to make much better parts.
We supply a Prusa Slicer profile at point 5.8 of this article.
Thank you for using Bondtech 🙂

Hello!
I did a modification on the runout sensor mount, so it has a guiding wheel for filament coming from the top of an enclosure. I have posted photos and was asked to share the stl. I have not found license information on your site, so I wanted to ask whether this is permitted under your license.
Nuno Santiago
says:
Hi Kai.
No problem at all from us. We supply the STEP file precisely so users may change it if they need to.
Enjoy your CR-6 with LGX : )
Nuno Santiago
says:
Mick,
It should work with any hotend compatible with the CR-6 SE that you may mount at the same location and position as stock.
You may need to adjust the length of the PTFE tube though.
Regarding fixing the tube.
As you know, during bed levelling the nozzle is pressed against the bed.
This causes the flexible section of the mount late to oscillate.
It is recommended to have some slack on the tube so it floats slightly when the nozzle is pressed.
Otherwise it will cause unwanted stresses and disturb the bed levelling.
The floating may occur inside the LGX’s push-fit connector.
Nuno Santiago
says:
No, we don’t have profiles for Cura to use the LGX on the CR-6 SE.
The slicer we use internally is the Prusa Slicer.
We got better results with it.
If you want to use Cura please take a standard profile and adjust it with some settings we recommend:
retraction speed : 35 mm/s
retraction distance (short bowden) : ~1.5 mm ~(0.4 + tube length(mm) x 0.015)
Remember to lower the current on the extruder stepper motor drivers, if you feel the stepper motor too hot to touch.
Thank you for using Bondtech LGX 🙂
Hi Keith,
“Print” the following g-code file to set the e-steps value to 562 :
https://www.bondtech.se/wp-content/uploads/2022/04/set-e-steps-to-562.zip
This file uses the M92 command to change the e-steps value and saves it to the EEPROM with the M500.
Mind that the M92 command is also set on the Start G-code we supply. We recommend you to apply it.
Thank you for using Bondtech 🙂

Hello,
What is the length of the tube between the LGX and the hotend? Reference: Section 5. Be aware of the following (Paragraph No. 2). I’ll probably buy the LGX when it’s available for the CR6-SE. I installed Sebastiaan Dammann’s Community Firmware.
Thank you

Hi Daniel,
The length required for the 2/4mm PTFE tube is 90mm, as mentioned in the “1. Source these items” section.
Thank you for using Bondtech.

Hello Nuno,
I specify my request, What is the length of the blue Capricorn tube at 3:38 minutes of the video guide?
Thank you

Hello Daniel
The PTFE tube between the GLX and the hotend in my case (I use a hotend from microswiss) is 64.44 mm. The right length is very important! For a long time I solved the problem of bad prints, jumping of the GLX drive. I had a short tube… Filament in the hole between the GLX and the tube twisted… After editing, the prints are amazing!
Hi Daniel,
Thank you very much for sending us your feedback.
Did you used the method we have on the Arrow Upgrade Kit setup guide to cut the tube at the right length?
/product/lgx-lite-arrow-upgrade-kit-for-creality/#accordion-item-4._cutting_the_capricorn_tube_the_right_way
Or are you using a Perch setup?
Nuno Santiago
says:
Hi Judge,
The runout sensor mount tube fitting can be used with a Push-fit clip. That will help.
Currently we do not have any model for a threaded push fit connector.
It could be interesting to look for offering this.
If your tube is not secured, maybe you can re-print the runout sensor mount with more flow so the tube collet sits more secure in the push-fit groove.
Thank you for using Bondtech : )
Sorry for the delay.
