V90

V90 Milling Machine

• The bed is 12" x 18". The cutting area is 11" x 17".
• Takes G code only.
  • pycam works well to convert an STL model to G code for the V90
  • If only drilling holes these online tools work well
• To start the software, click on "V90 router" at the bottom
• Takes 1/8" shanks. You can buy bits at Precise Bits
• When installing a bit, there is a coned spacer. The cone part goes up.
• There are limit switches to stop the machine from damaging itself if it goes out of bounds.
  • The limit switches are in series so if one is tripped, the machine will stop and not know which one tripped it.
  • If a limit switch is tripped, disable the stepper motors then move the stepper motor shaft until the switch is no longer tripped.
• For the G code, the cutting motor control doesn't do anything. Turn the motor on and off with the hardware switch and adjust its speed with the speed controller knob inside the machine.

handy G Code to know

• G20 - inches
• G00 - move fast (position to new area)
• G01 - move slow (cutting)
