Before finetuning my xPRO settings on an OX CNC, I decided to upgrade to the latest version of GRBL. following along the instructions on the Wiki, I downloaded the HEX file grbl_v0_9i_atmega328p_16mhz_115200.hex and used Xloader to load it to the xPRO/Arduino. This all seems to work, ie no error messages, and LEDs are flashing for about 10 seconds and the status line shows 'uploading...' But after this, the status line in Xloader shows '0 bytes uploaded'. When verifying the version in the xPRO, it is still V0.9g Any hints as to what I am doing wrong ?
