Hello all, I have had my Mendel90 for a couple of years and apart from building it, I haven't had to do too much with it in terms of set-up. I was set up on a old windows laptop which has recently passed away. I have tried setting the Mendel90 up our new apple laptop,with relative success. I have the FTDI drivers installed I have Pronterface communicating with the printer and I am able to home all the axes etc. But, I wanted to alter the firmware, so I downloaded Arduino, and opened it up. I then went to the SD card (supplied by Nophead) to copy across the Melzi folder into the hardware folder - and wasn't there! I must have moved rather than copied when i originally set it up. I have tried using sanguino files and also have GEN 7 listed under tools / boards but no Melzi. I have changed the display in Arduino to verbose during, and I have tried holding down the reset button. The jumper is installed on the board. Can someone please tell me where to get the missing melzi files from so that I can update the firm ware?
