Geeksbase Ramps PCB V1.3
This is our new complete electric for the reprap printers on one PCB. Base is the arduino mega!
We changed some things to make a better reprap-pcb.
The PCB can manage two extruders!
All traces are bigger to provide a better current flow!
On the whole pcb we designed a “hatch”. The effect of the hatch is that the whole PCB works as a cooling element! So all generated heat discharge perfect and the operating temperature stays in a perfect range.
All screwed contacts where replaced against male/female connectors.
So you could change the whole electric and single parts really fast. We dont use many SMD-parts. So the stepperdrivers are replaceable. We only deliver the Pololu A4988, which has a automatic overheat-automatic
With the Arduino Mega as base its possible to build reams of addons. (like display, keyfield, etc.)
