I adapted China air cooled spindle with GND to be save when Spindle get’s an electrical damage. (Did for 800W and 1.5kW spindle from different sellers) –> Spindel outer diameter 65mm Print orange part with 3d Printer –> File as GCode attached to this post. –> ABS Fillament used 10,35m 1.75mm –> It tooks me about 4.5 hours to print on my 3d printer Should work for all air cooled China Spindle

Needed Parts: 1 x Lumberg LUM 0318-04 1 x Lumberg LUM 0322-04 3m x Ölflex 110 CY 4G 0.75mm^2 3 x M3 x 45mm 4 x M3 x 10mm 1 x M3 x 8mm 4 x Mutter M3 1 x Kabelschuh M3 –> Connection Ground (GND) I used only three M3 x45 screws because the 4th thread is used to connect grounding to the spindel. Remove the distance holder to get space for the screw to connect GND to spindle

Plug connection:

PIN 1 –> Cable 3 PIN 2 –> Cable 2 PIN 3 –> Cable 1 PIN 4 –> GND If spindle turns in wrong direction after connecting to inverter, exchange cable (ex. PIN1 and PIN2) –> Now it should turn in correct direction.

Hello all, Currently I’m going to adapt my Arduino 9 Shield Board for securing my CNC Maschines against unallowed access. Code has been used together with an older Arduino Nano Shield. Following fuctions are implemented:

  1. set master iButton with first use
  2. delete all allowed iButtons except master
  3. add new iButtons
  4. 1-Wire Temperatur
  5. show hours since switch on
  6. list all Hex-ID’s of allowed iButtons during startup
  7. show status with IButton Reader (green (ON) or red led(OFF))
  8. switch relais on/off if valid iButton as been touched on iButton Reader
  9. emergency Button push controll (switch off releais)
  10. display DS1307 (RTC) time
  11. correct time with spare Arduino Nano V3 durring upload –> new time will be programming time

It’s very important to have a clamp with a run out (circulation) as small as possible. See picture bellow (left I used a bad clamp and on the right a good one). With same mill

PCB on the right has been milled with about double feed rate
Used tool 60° VHM Mill

Generation Options
Feed rate X,Y: 500mm/s
Spot drill holes: -0.55mm
Minimum: 0.0254mm
Maximum: 1.6mm
Step Size: 0.127mm
Maschine Z Down: -0.2mm
Tool Dia: 0.23094mm
–> dependend on ZDown and Mill° (60° and -0.2) –> Calculated –> (tan(30°)*2)*ZDown= 0.23094mm

Angle ° Z Down (-) Tool Dia
60° 0.2mm 0.23094mm
60° 0.15mm 0.17324mm
30° 0.2mm 0.10718mm
30° 0.15mm 0.08038mm
