Description

Bargain - Original DUEX4 V0.2 Expansion board for DUET 3D Printer Controller

The Duex4 is a 4 channel expansion board for the Duet. It adds 4 further stepper drivers, 4 more FETS for extruder heating, 4 temperature measurement channels and 4 endstops. In combination with the Duet this allows for a 3Axis printer with 5 or 6 extruders (5 Extruders if paired with a Duet 0.6, 6 extruders if paired with Duet 0.8.5). It uses the same stepper drivers, FETs and digital current setting controller as the Duet and is connected with a (supplied) 50 way ribbon cable. It is Open Hardware, both designed and manufactured in the UK.

IMPORTANT NOTE

This is the original Duex4 V0.2 which does NOT have an analogue GND. As described this blog post: http://blog.think3dprint3d.com/2015/04/duex4-v02a-minor-updates.html, this omission leads to noisier temperature readings on the expansion board than on the Duet (as documented with a fix, by David Crocker). Most users have not found this to be a problem.

The RepRapFirmware supports Duex4. We recommend DC42's Fork available here:

https://github.com/DC42/RepRapFirmware/tree/devNote that you should set the Duex4 thermistor series resistors to 1k in config.g.
