Configuration for a Triple Head 3D Printer
Open Source Hardware
R1001: 2A Stepper Motor DriverThis is a NEMA stepper motor driver based on TI's DRV8825 chip, It's a high-performance stepper driver capable of micro-stepping at 1/32 resolution. Current can be digitally set for every driver at 10mA increments. Every R1001 includes temperature monitor that helps detect overheating.
R1002A: Quad 1A DC Low Side NFET Control SwitchesThis module can control 4 small functions (i.e fans, LED's) that consume less than 1A and runs at the high input voltage.
R1007: Quad 20A DC Low Side NFET Control SwitchesThis module can drive 4 heaters with strong 100 Amperes PSMN1R2-30YLC,115 NFETs from NXP, allowing steady and cool driving of 300+ Watts head beds. R1007 must be powered through its own auxiliary supply input and it is optically isolated from the base R1000A or R1000A-10 board (meaning, it can have its own separate power and ground up to 24V apart).
Upgrade or Expand
The modular nature of the JuicyBoard platform allows for easy future upgrades such as a stronger motor driver. This can be done easily by swapping modules without the need for a major board redesign.
In case any of the modules fail for any reason you can swap it with a new one, avoid PCB rework or even buying a new controller board.
Balance between customizing your application and cost. Only install the features that you need, no more no less!
