How to Enable 3D Touch on the KINGROON KP5L 3D Printer 

Modifying the cfg file if you can. Once you do, flash it and you will get the 16 point measurement you want.

See the following article, check the step 4, modify the cfg file then flash it. kingroon.com/blogs/3d-print-101/modify-mainboard-configuration-file-of-kingroon-kp3s

Yes I just received my KP5L and would like to know the same . I connected the two pugs to the main board as shown in the video and then downloaded the new firmware for kp5L (pre assembled version) from there website. The software reflash worked first time no issues. Though when I run a auto level function it will only probe in 3 positions on the left hand side of the bed and then one almost in the centre. The probe makes a strange vibration after each probe for a few seconds. Also now if I press the home all button the print head now moved to the right front of the bed like it's reverse . This is all strange behaviour so somthing is wrong. I confirm that I downloaded the software for KP5L. Video of how my kp5l behave now when I run a auto level. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8mRjXKBOXDU.html I had to put back the stock firmware and gave up on auto level for now. Even the stock firmware needs a change to the text file to get one of the steppers going in the correct direction. We need a working firmware that doesn't need messing with. I'm happy with the machine other than this issue.

Try checking the description.

hi, I had the same problem, did you find how to fix it?

Hi Jim, you are right, it can be installed on the left. Just need to measure and modify the Probe bed positions. As for the file, you can get them in the description, the first link in it. The files you mentioned may not be the latest.

@@Kingroon3DOfficial Thanks! I wasn't able to design or print a holder for left side installation. All interfered with the X-axis motor housing. Also my attempts to modify the cfg file were not successful (-54 mm from nozzle to point of 3D Touch). I believe @Brian Pickett offered a solution in that he simply hot glued a mount on the right side of the titan extruder housing. Also the robin_nano_cfg.txt still contains the command ">INVERT_X_DIR 1" which I believe should be ">INVERT_X_DIR 0"

@@endicott65 You’re welcome! Glad to hear the problem fixed. Have a nice day!

Not so soon, but I will try make it faster since I back for the projects. New tutorials and firmware will be. released soon.

You can find the link in the description, we will have it uploaded in the same folder. So the link will be always useful.

@@Kingroon3DOfficial There is another problem: when setting the table size to 310 x 310 mm in the CURA slicer and printing a 300 x 300 mm square model, the printer prints only 293 mm in the X axis, after which the plastic sticks in one line of the remaining 7 mm. Considering that this problem is not fixed in the slicer, it means that this is a problem in the firmware.

@@user-bz4ru3xz6t You can modify it in the cfg file, the coordinates of the 3D Touch detect decide the printer volume. Modify the file then flash it again.

Please check the motor directions first, then go modify the txt file, search for “INVERT” you can find the settings to modify. Change the 0 and 1, you can correct the directions. As for the z-axis motor, please check it’s connection.

@@Kingroon3DOfficial How can I do this if the firmware cannot be edited? The Z axes are connected and move when the axis move button is pressed, but do not move when the table is uneven when the printer is in print mode.

@@user-bz4ru3xz6t Please follow the steps in the video and use the original mount. And you actually can modify the firmware by changing the text file. After the firmware has been flashed, you can only flash the modified text file to load your new settings.

@@Kingroon3DOfficial Changed the inversion of the extruder in the firmware. everything is working. But the Z-axis motors do not move in time with the unevenness of the table, although not during printing, but during the verification process, these motors move along the Z + and Z- axes, which indicates their connection. In addition, after checking the height above the table with a sheet of paper, the printing process cannot maintain this height and the nozzle is still at a considerable distance from the table. What should I do? Maybe something needs to be changed in the firmware?

@@user-bz4ru3xz6t Do a manual bed leveling before installing the 3D Touch. You can do it twice to make sure. For the second issue, if the probe value is not remembered, do a second time. If still does not work, please send a video to support@kingroon.com to show the problem, we will check that for you. Thanks!

Do you use the one in the firmware files? The first link in the description.

That means that something wrong happened when flashing the firmware. Please flash it again and see if anything changes. We suggest to use a different SD card or format the current one. As for the wrong direction, please check below article to modify it, the step 4. How to Modify Configuration file for the KINGROON KP3 Mainboard kingroon.com/blogs/3d-print-101/modify-mainboard-configuration-file-of-kingroon-kp3s

@@Kingroon3DOfficial I formatted the SD card and flashed the firmware again. However, the screen went blank in the same way. I tried several times but it did not work. Also, the level sensor sometimes comes out during printing, and even though the nozzle and heat bed are aligned in height, there is a gap of about 2mm between the nozzle and bed.

@@yoshiyu9691 Please send an email to support@kingroon.com with a video that can show the problem and the connection on the mainboard, our guy will do a further check for you. You can also flash back to the stock firmware and make sure it works fine under that. Waiting for your email. Have a great day!

@@yoshiyu9691 hi, what was the solution, mine is showing the white screen also.

We will try add that in our website. Please also check that in Local store.

@@Kingroon3DOfficial do you know the length? Was it a 1.5M cable? Found one on Amazon.

@@brianhilligoss I forgot to measure that. I think that’s enough.

@Kingroon3DOfficial I have the same problem

@@jenik100 just let me know if can fix it

@@jenik100 i recommend you to flash it with better version of marlin, you can find it on thingverse, 3 files, just make sure to run the PID test after flashing, you find it direct on the display options, then store settings. bye

Hope you have got the help from the email. If you haven't please send email to support@kingroon.com.

Did you manage to fix the screen going blank white ?? Mine still the same.. It turns white during printing. It's really annoying...... This is obviously a firmware issue, and it doesn't seem they are releasing any firmware updates for it. I think i'm going to put this thing on the shelf until an update fix is released. In the mean time, i will have to shop for another printer.

@@gconol I took the leveler off and reflashed to stock. That also came with the same x-axis issue, so had to do that twice too, to get the X-axis to work. Jut annoying and unnecessary. If it were my product, I would make sure these files actually work before I put them out there. Must be the Dutch in me..... So long answer short. I gave up on the leveler for now.

@@sxmtaekwon-do7685 I agree. Unfortunately, I don't think It's worth my time or effort to do all that. And also, a large bed printer really needs an auto leveling feature so I'll keep it for now. However, This should have been installed from the factory in the beginning, and I would have gladly paid extra for it. I was really happy with my old K3PS which is why I bought this big printer, but this one got me very disappointed.

i'm having the same issue, if you find solution please let us know, im my case, the needle even goes down on the first point, it just goes to the center and park there

Klipper works differently. Please check our video on it, get the Klipper Bundle to use. To use 3D Touch with Klipper firmware, you need to do some modification to enable it. Here is the link for your reference:www.klipper3d.org/Config_Reference.html

@@Kingroon3DOfficial Спасибо, я смотрел видео и делал все по вашей инструкции. По вашей инструкции sensor_pin: должен быть ^PA11. Но с такими настройками не работает. Т.к. PA11 - это датчик ZMIN. Если я делаю не по инструкции, т.е. вместо ZMAX я втыкаю разъем в ZMIN - то на комманду QUERY_PROBE начинает реагировать. Но это считаю небезопасным отключать ZMIN. Подскажите, пожалуйста, название контакта ZMAX в Klipper. Для ZMIN - это PA11, а для ZMAX какое?

@@user-fm9ke2nj1k Hi, we haven't use 3D Touch or BL Touch yet in Klipper, but its support should be available soon. Now its test are not ongoing. And it is quite different to use it in Klipper. If you cannot wait, here is a Klipper project for our printers, it might help you out. github.com/nehilo/Klipper-KingRoon-Printers If you are use the stock firmware we provided and get problems, please send the video to support@kingroon.com, so that we can see the issue more clearly and help you better. Thanks!

@@Kingroon3DOfficial Спасибо, я подключил 3D Touch в разъем вместо ZMIN. Klipper с 3D Touch у меня теперь нормально работает. Если делать по вашей инструкции, т.е. разъем с двумя проводами(белый и черный) воткнуть в разъем ZMAX, то в Klipper работать не будет, т.к. вместо PA11 нужно указывать порт ZMAX, какой номер PA я не знаю. Спасибо за помощь!

@@user-fm9ke2nj1k You are welcome and thanks for the details. We will get back to Klipper soon. Please remember to go over the required process while using it, like measuring resonance and pressure advance, it will help to improve the printing. Have a great day!

The new firmware is already in development, hope it will be fixed soon. As for the source code, I will ask our engineers and see if we can provide that. Thanks for pointing that out!

In case someone is having the same issue: You can use the old KP3S firmware drive.google.com/file/d/1mSXZBLzWFwz71TwLO893RK2lJLcrCqDr/view?usp=sharing%C2%A0 with the KP5L config file. Just enter the correct probe offset in the config file, or send M851 gcode through serial to change it on the fly. You won't need to set it again unless you change the probe height significantly.

@@Kingroon3DOfficial Wen is soon exactly ??

same problem do you fixed this ? can i get you fimware for fixed ?

@@glitchygarden6973 hello xD, how did you manage to do that? if i flash the KP3S, after auto levelling doesnt show me the Z Offset option =/

What the firmware do you use and what filament do you print? We will look into it and find out why.

@@Kingroon3DOfficial I got it from here. It works but it my screen will go blank and just white screen until I reboot the printer. I have to do this every time I finish printing. drive.google.com/drive/folders/1GKgxuKroyt9iPF51nZn2M2NoDaWLn_1Y I tried the one in the link you posted in the video, but my printer didn't work. Instead, it installed firmware for CNC drive.google.com/drive/folders/1VwMxSzd7p6GQ5RVwoHhlUCJpMXhC-gdx I use ESUN PLA+ filament, but I don't think it has something to do with the filament. This is a firmware issue.

@@gconol Please use the firmware from the first link of the description. And send a video to support@kingroon.com so that out guy can do a further check and find it out. Please make sure we can see the connection on the mainboard and how the printer works. If you have any photos that shows the white screen, please also send that. And we will do some checking on the published firmwares to make sure they’re correct and updated. Thanks!

Not so soon. The team is still working on it. We will let the public know once it is ready. Thanks for your support!

It is in the description, the first link.

Please check the first link in the description. We put the stl files inside the folder. And I just checked it again, the file is correct.

@@Kingroon3DOfficial I also checked this file in CAD, the file is actually skewed, although it can be corrected in CAD, it's sad that the raw holder file is used as a basis. Тоже проверил данный файл в CAD, файл на самом деле перекошен, хотя его можно в CAD и поправить, печально, что сырой файл держалки используется за основу.

@@PETROVICH4YOU I will let our guy know that and see if they can do anything about it. But honestly we haven’t had any issues on it.

Sure, we noticed that. And it could be different on 3D Touch and Bl Touch, so we do suggest connected by pins. Just check the diagrams on both sides and make sure the connection is right.

Sounds like your 3D Touch is active. Please make sure you are using the same mount like we do and followed all the steps. If you did, please send a video to show the issue to support@kingroon.com, our technical team will help you out. To use the manual bed leveling, please flash the stock firmware and unplug the pin on the 3D touch. Thanks!

You can contact support@kingroon.com for help. New firmware and tutorials will also be available soon.
