I damaged my Melzi which worked fine for 18 months atmega644p.
Think I bricked an intended replacment 1284p. should have been a straight swap in.

The first 644 board had trim pots which were easy to set : turn anti cockwise till stop then 1/3rd clocwise. worked first time no problem.

the 1284p board tirm pots were rubbish kept turning , so no end stop point. leads to voltage testing pita with small solder tags , 3 hands needed erratic readings, etc. Also build quality felt not as good as first board.

2nd one likely bricked , need another board:
Option to future usea lcd display is a bonus, not esential.

But :
trim posts with proper stop point
pre loaded firmware
decent build quality.


think supplier of original board no longer in business.

So.. where to buy another Melzi from?

Thanks

Nophead has Melzis built for his Mendel90 kit. They are factory tested and motor currents are accurately preset. I would suggest sending him a PM and he will probably sell you one.
