Thanks for your advice

​@@flsun3dprinterservices am I right or is it a misinterpretation on my side?

Sorry for the inconvenience caused to you

@@flsun3dprinterservices THERE ARE SCREWS IN THE PRINTER HEAD NOT INDICATED IN THE VIDEO. THIS IS NOT THE SAME PRINTER THAT I GOT.

Hello.It's Silicone grease

@@flsun3dprinterservices Tks! I need add that it's not just Silicone grease, but a silicone grease with teflon (PTFE). It's a expensive grease, not an ordinary silicone based one. (I've doing some research after asking you. :) ) I just googled "tube grease p/n 6020A", what's impressed on the tube provided by flsun that came with my SR. Tks for your fast reply! :D

@@mtrivelin Sorry, I checked. This is lithium based grease

@@flsun3dprinterservices Thanks for the feedback. The situation really isn't very clear. 🤔 I redid the research and on the first website that appeared here it says that the product is "a dielectric grease, which does not attack rubber or plastics". This is a description of a silicone-based grease. On another website, it says that this product is a lithium-based grease. Something isn't right. I need to find out the manufacturer of this product to be sure of what we are using here. In my experience, it is almost impossible to apply grease to the rails without ending up staining the belts. If this grease is actually lithium-based, the rubber on the belts may deteriorate more quickly. A silicone-based grease with Teflon would be an ideal product, I suppose. Could you be so kind as to re-check your information to make sure? There is no need to be in a hurry to respond. Thank you very much for your time and attention.

@@mtrivelin May I ask if you saw the introduction from our official website? I checked and found that the composition of this grease is indeed lithium based grease. It is true that the grease may stick to the belt when applied. But you can rest assured that this will not affect the belt.

@@flsun3dprinterservices I will do that when I get home from work. Not sure what the issues with it is.

HI.The speeder pad does not need to update the firmware because there is no new version yet. And the 1.4 version firmware can only connect to the V400 printer.

@@flsun3dprinterservices My speeder pad screen is stuck, and it won't let me change it. The Moonraker portion won't update either. I'm not sure what is wrong with it. I have tried several times to update Moonraker, and I get an invalid code and it tries to update then it gives me a git clone error.

Hello. Monnraker being invalid will not affect the printing effect. You can solve this problem by flashing the pad with version 1.2.1. Firmware download link: drive.google.com/file/d/1oWyyYvqUH6pRGAj41ty1bvByr01L5WFe/view?usp=sharing You can refer to this video link to operate: th-cam.com/video/hdn4WHEQZwU/w-d-xo.html@@InTheDogHouse3DPrinting

@@flsun3dprinterservices I was able to download everything and used raspberry pi to install the firmware and install it onto my speeder pad.

Hi. You can operate it in power-off state.

Hello friend.You can print this test model to see if the same situation occurs: drive.google.com/file/d/1lAFH-b2EXnnV85e6YEvzWuhP772tqS7q/view?usp=sharing You can also contact our after-sales email: service@flsun3d.com Whatsapp:+86 138 3861 7313

Can I ask if you mean that the heating rod and temperature sensor on the nozzle cannot be removed?

You can download it at this link: drive.google.com/file/d/1zgMkPFHU2qQjkVX1lVGMBkwCT16K610-/view You can print this tool in advance. You can use it when you need to adjust the belt tightness.

Hello friend. We recommend that you use a 4-8GB MicroSD card to flash the motherboard firmware. The format is Fat32.

github.com/Flsun3d/FlsunSlicer/releases

Hello friend. We will update the video on replacing the nozzle and replacing other accessories in the future. You can stay tuned.

Hello friend. You can send the error picture to our official email: service@flsun3d.com or Skype: live:.cid.378da589d962e676 This way we can judge for you faster.

You can disassemble the upper case of the printer and see if the motherboard fan is spinning.

For specific solutions, please contact our after-sales email: service@flsun3d.com

You can use a Raspberry Pi to format the SD card. For specific operation methods, you can contact us through the after-sales email: service@flsun3d.com

Hello friend. You can take a look at this document to see if it helps you: 43.156.146.232/en/home/SR/troubleshooting/UnabletoreadSDcard

Hello friend Invalid mooraker will not affect the printing effect. You can flash version 1.4 firmware for the pad. Regarding the camera, it needs to support the UVC protocol and have a USB interface.

Hello friend. The belt needs to be replaced when it stretches.

@@flsun3dprinterservices Ok...How do you know when it has stretched too much? I'm having trouble with my prints, and I can't figure out why. I've only logged about 400 hours on the machine, but it fails on every print after about six to eight hours of printing - it just veers off and ruins the print. I then regrease the arms and double check the belts are at proper tension, then it does the same thing - prints for 6-8 hours and then fails. There is no visible wear, and they don't seem to be losing tension and yet I cannot complete any larger prints. I have slowed the print speed, I have used the recommended setting - the only thing that helps for a short time is regreasing the arms and checking the belts.

@@tattoodude8946 Hello friend. Regarding checking the belts, you can refer to this link to carefully check whether the three belts are stretched or deformed: th-cam.com/video/RoGGZYt_2QA/w-d-xo.html Then you can refer to this document to see if it has any effect: 43.156.146.232/en/home/SR/troubleshooting/Problemswithprintingmodels

@@tattoodude8946 One of my SRs has a little over 4000 print hours on it and the belts still look fine. They are the original belts. I would like to replace them but number 1 rule with 3D printers. If it is working, leave it alone.

You can be assured. S1/T1 will automatically update the time after connecting to the Internet. If you update the V400 pad to version 1.4, the time will be automatically updated when connected to the Internet.

Hello friend. If you update klipper or the system, you need to update it through the web terminal. If you update directly on the pad, the update will fail.

Hello. This is to solve the problem of uneven the hot bed. If the heated bed is uneven, one side of the printed model can stick to the heated bed, but the other side cannot.

Can I ask if you mean by clicking pause and then clicking resume printing to have no effect?

Hello friend. We will not delete comments. It may have been deleted by the system. You can try flashing firmware version 1.4.1 on the pad to see if it has any effect.

Hello friend. Generally, the accelerometer is only needed when replacing accessories. To calibrate the size, you can first measure the size of the printed model to see if there is any problem.

Hello friend.You can use PLA filament to print.

Can I ask if the logo light flashes when flashing firmware on the motherboard?

@@flsun3dprinterservices no it’s not.

Hello friend. SR can only be connected to speeder pad. That is firmware version 1.2. Pad firmware version 1.4 can only connect to V400. The steps for using the accelerometer on SR are similar to those for connecting V400 to version 1.2 pad firmware. You can refer to this video link: th-cam.com/video/kFdS4WXdz0Y/w-d-xo.html
