We made Mantis 9,1:

Here are instructions and step by step instructions in making the Mantis 9.1

• http://makeyourbot.org/start

We did have inventory.

• http://makeyourbot.org/mantis9-build

Spindle making

• For the spindle making we used the low cost spindle 1.0 http://makeyourbot.org/low-cost-spindle-1-0

Spindle

The 3 axis motor

• This is the stepper motor we use for the 3 axis sleds [1]

Board making

3 axis parallel port interface 1.0

3 axis parallel port interface 1.0

Cables

XYZ_board

USB_->_Fab_Net

076-_004_board

076-_001_board

You'll need to make four different types of circuit boards:

• QTY 1 Fabnet Adaptor Board (076-000a) [2]
• QTY 1 Stepper Motor Controller (076-001) [3]
• QTY 1 H-Bridge (076-004) [4]
• QTY 3 D.Carr Driver Boards A3982-1.0 [5]
• QTY 1 3 axis parallel port interface 1.0 [6]

FabNet

serialport = self.open_serial_port(fabnet_port, 38400, 0.2) -> serialport = self.open_serial_port(fabnet_port, 19200, 0.2)

Programming the control board

• mega88 load hex file: avrdude -p m88 -c bsd -U flash:w:file.hex
• mega88 use 16 MHz xtal: avrdude -p m88 -c bsd -U lfuse:w:0xDE:m

Programming the H-bridge

• mega88 load hex file: avrdude -p m88 -c bsd -U flash:w:file.hex
• mega88 use 20 MHz xtal: avrdude -p m88 -c bsd -U lfuse:w:0x76:m

Software

• EMC
• cad.py

Questions and thoughts

• How do we combine
• before making the spindle ->

• On the Fab Net, suggestion, to help debugging, it would be good to have leds on transmit and receive, to be able to see if we are transmitting information or not.

Put prepackaged Mantis 9 configuration files folder in:

/usr/share/doc/emc2/examples/sample-config
