Im having a problem with the program. Might be my wiring but I don't think so? Works fine without BLtouch

https://www.youtube.com/watch?v=GAJai3IcUfY Here's a video showing the problem

• Not Zeroing on the Z axis and only going up.

Flashed the given GD32 bin and set up my printer.cfg. the print works fine if I don't use any tmc 2208 cfg but when I do, it instantly throws an error when I try to move.

You are using 0.650 for the run_current on the x,y,x steppers and 0.500 on the extruder. Where did you get the specs for these motors? When I asked Kingroon I got conflicting information - 1.5A and 1A which is probably max not RMS.

is there a cfg for kp3s pro please?

I have made sure that the wiring is correct and I have it plugged into z- where the z endstop use to be at. I have tried different cables and a clone with the same results

The MOSFET on my KP3S-3.0 was damaged in short mode. At that time, the runaway heater Bed rose to 116℃, but since the max temp value was set at 130℃, power continued to be supplied to the burning MOSFET without triggering an emergency stop.

Considering individual differences in thermometers and usage environments, it is recommended to lower the max temp to 105℃. It is also necessary to add a comment in the code that if the max temp is set above 105℃, there is a possibility that an emergency stop may not be triggered.

The max temp of the Extruder is safe at 300℃.

For some reason its not centering the nozzle with the bltouch x_offset and bed_Mesh just stops after the first probe.

KingRoon is referring to your repository in their KP5L Klipper Guide, and many comments reports communication issues with TMC drivers.

Looking though Marlin's configs and board definitions, it seems to have the drivers them configured in non-standalone mode and communicating with them through PD5/PD7/PD4/PD9 for X/Y/Z/E.

Could there possibly be different board versions for this printer?

I don't have a KP5L for testing, I was simply trying to help a user, but they haven't reported if these pin settings works.

Brand new to Klipper so I have no idea what to do or even where to begin.

I am using the Stepper.cfg file that is available.

Hi,

I do not know where to find the information and tutorial on how to flash a boot loader on the Kingroon KP3s.

Can you help?

The link for the v1.2 YouTube vid leads to the v1.3 video and v1.3 leads to the v1.2 vid

Is there any way to use stock KP3S LCD with Klipper firmware?

I'm a newbie, I'm learning now, I'm having trouble identifying where the start macro is, so I can put the option to load bed_Mesh

I am getting this error when trying to print

Unable to read tmc uart 'stepper_x' register IFCNT

logs are not very helpful either

klippy(12).log
moonraker(5).log

Hi nehilo, could you please also provide the screen config for KP5, or point out which config we can use in klipper's repo. Thank you

please help me :)

I would like to fork this repo and add some change based on my printer. Then I found this is a no license repo, it makes others hard to work on / share / use this "legally". Could you please add a LICENSE for this repo. It would be good if it is BSD or Apache2. Thank you.

Kp5L bltouch fails to deploy. Bltouch is a 3dtouch provided by kingroon and I followed instructions on their site to wire the probe.

Hello,

Why do you list using the pins on one side of the board to setup UART mode here: https://github.com/nehilo/Klipper-KingRoon-Printers#tmc-uart-pin-kingroon-13-motherboard--for-advanced-users-

I have read the TMC2225 datasheet. The box at the top of page 16 says, "The UART line must be logic high during idle state. Therefore, the power down function cannot be assigned by the pin PDN_UART in between transmissions." The 20k resistor (marked "30C") for the TMC2225 pin 17 (PDN_UART) is connected to ground. In other words, the resistor must be removed to enable UART mode just like you mentioned.

The part that I do not understand is why you are not using the jumper pins on the soldering pads near each of the 20k resistors. These jumper pads are connected to a GD32F303V pin and to each TMC2225 pin 17 (PDN_UART).

• X Axis = p30 / PA5
• Y Axis = p7 / PC13
• Z Axis = p64 / PC7
• E0 Axis = p68 / PA9
• E1 Axis = p67 / PA8

I think the hotend fan should also get moved from the JST connectors with 24V power to the HE1 screw terminals. This will enable the fan to be turned on only when the hotend is hot or a print is running. It will also enable users to tune the fan speed with PWM and perhaps run the fan quieter.

I would appreciate full board schematics to avoid the need to reverse engineer more of this. I would also like to get the screen working with Klipper. I need the documentation like what kind of driver this uses or what Makerbase screen module version/code this is based on.

I did follow the video to connect 2pin to Z+ and 3pin to BLT, and ensure the GND is on correct pin. I got "BLTouch failed to raise probe" error and pin_down does not get open on QUERY_PROBE.

config is same as this repo
