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:
set master iButton with first use
delete all allowed iButtons except master
add new iButtons
1-Wire Temperatur
show hours since switch on
list all Hex-ID’s of allowed iButtons during startup
show status with IButton Reader (green (ON) or red led(OFF))
switch relais on/off if valid iButton as been touched on iButton Reader
emergency Button push controll (switch off releais)
display DS1307 (RTC) time
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
Created new Arduino Nano Shield Version 9 Arduino Nano Shield which supporting all current Maxim Thermocouple Chips – MAX31850 1-wire – MAX6675 I2C – MAX31855 I2C PCB is prepaired also for following option: – DS1307Z Realtime Clock – 1-Wire devices (ex. DS18S20,../blog../blog) – 3.3V voltage regulator LM1117MPX-3.3V – 5V oder 12V voltage regulatorr LM2937IMP oder LM340 – Relais G5V1 5V oder 12V You can connect a 2×16 LCD Display: – HD44780 LCD 2X16
Don’t care if they need 3.3V or 5V or if thermocouple has to be grounded, everything is implemented to get them running with different assembly options
If you are scared about soldering the MAX31850. It’s really simple if you do it in the following way:
1. Clean the PCB 2. Put some solder on the MAX31850 pads, there should be some smale solder balls on the pads 3. Place carefully the MAX31850 on the PCB, take care align it correctly to the solder pads on the PCB 4. Take an air rework station to fix it on the PCB, the solder has only to fix the chip. It will be soldered in the next step 5. Put a little flux paste beside the MAX31850 chip 6. Solder it with a soldering iron on the PCB 7. You can see that it’s good soldered when solder is covering the hole pad on the PCB
