I tested it in cura4.5, but I think this problem has nothing to do with the version. I will use a larger file to test it.

@RAFALFRY Hello, this looks like an error in the file data transmitted by wifi, you can try to format the sd card, or change to a more stable network

@SkipperDo @BenediktS Hi，In fact, you can check your version in the about screen, this V3.0.0 is just the version of the bootloader

https://github.com/makerbase-mks/MKS-Robin-Nano/tree/master/Nano%20firmware%20v2.x.x

This problem has been fixed in the V2.0.2 version, and the source code has also been updated

[robin_nano35_cfg.txt](https://github.com/makerbase-mks/MKS-Robin-Nano/files/4396565/robin_nano35_cfg.txt) I use this configuration file is normal, you can modify some parameters, such as pulse, motor direction, etc., and then try to use on your machine

 Hello, what I marked with a red box is the TTL pin that drives the MOS tube, which can be configured as a laser control pin

@FabioMC @Aritzobixo Hello, PA8 (BL_TOUCH signal pin) or TX and RX pins of UART3 can achieve this function.

S is PA8 (signal pin), you can see the pin number on the back of the motherboard

In this case you can use uart3's tx or rx pin
