The Hackspace Router - work in progress

YOOCNC 4030 mill connected to an Arduino running GRBL

Spanners: 13 & 17 , ER-11 Collet

Parallel port pinout

Milling Bit Settings

Refer to this table of Mill Settings for suitable parameters.

Software settings

Universal G-Code Sender

Do Not use the Return to Zero button, it does the wrong thing.
Instead set a macro button to 'G90 X0 Y0 Z0' to return everything to working home.
Commands G54 - G59 select the current working home "set"

Previous Suggestions

• Very noisy in operation
• Very messy, will need some kind of vacuum to remove particles
• Can carve out PCB circuit boards
• Can engrave most materials
• Can cut softer materials like wood and thin aluminium

Suggested Suppliers

Shapeoko 2 - Full kit - $695 + shipping + vat/duty

• Full kit, everything we need to build one
• Going to get hit for import duties.

Shapeoko 2 full kit - UK £661.15 delivered

Amber Spy Glass eShapeoko + upgrades - circa £450

• Buy eShapeoko mechanical kit £237.50
• 500m Dual X Rail £24
• metal spacers £6.75
• NEMA17 motors x 4 - £50 ish
• stepper shield + arduino
• 24v power supply
• rotary tool e.g. dremmel

In a build/upgrade your own kind of a way, useful info is:

• GRBL - CNC milling control for Arduino 328 (uno) boards
• GAUPS 40V - Stepper shield, DRV8825, upto 45v

Discussion

I'm a bit concerned about the eShapeoko not being the same as the Shapeoko 2, where we would lose the benefit of discussing problems/upgrades with the Shapeoko 2 community - Gerrit, 1 August 2014

this is the approach that London Hackspace took to get their Shapeoko2 - Justin, 2nd August 2014
