No single.
Well that's certainly cheaper than what i looked at thanks.
The driver I am looking at is around 29 pounds, and I have to get a 4 axis Bob as mine is a 3 axis (has to be USB controlled 200khz as I have no printer port = 65 pounds)
To get a double head setup.....buy two extruders and 2x nozzles ??

I guess the bed on ebay is "slightly better" as it comes complete, but then there is an added post charge. Does nobody make larger heated beds ? I'd like one the same size as my cutting bed 500x300

Apart from all the parts above and a custom made Z plate adapter for all of it, is there any other hardware needed (apart from cable/connectors) ?
