| Servo Driven 4th Axis for CNC Mill |

So now I'm waiting for the transformer to be delivered - (expected middle of next week) and also the air solenoid for the brake operator, which should be here already but isn't :( . . . getting impatient in my old age :lol: |
| Pete.:
I have a couple of 12v air solenoids left over form a project. Got some random servo/stepper drives too I'll be selling soon. You could have had one of the soleniods for your project Andrew. |

Pete that is very kind. The requirement is pretty specific - 5 port with 1/8" bsp tapping and 24 v DC coil, also physically small. Hopefully the post man will bring it today ! |

Well time goes by - I've made quite a bit of progress, but some has been up blind alley ways :bang: Firstly, in the picture above where I've mounted the Bosch servo card with it's associated choke just below it - I've had to re-locate the choke, as I found a tiny little paragraph tucked away in the Bosch manual saying that the servo card must be at least 300 mm away from transformers and chokes - it is presumably susceptible to magnetic fields. I'm sure that they are closer than that in Bridgeport Interacts ! I wanted to have the 4th Axis with it's cables easily de-mountable, so have placed a termination box on the machine right hand side where the Encoder, and two Adaptaflex covered cable forms will plug it. This also has a rotary enable / disable switch |

Now getting wiring to that point was a bit of a b****r to say the least. There is a semi-protected way in which the power for the machine light runs in armoured cable, but although protected by shields, it is in the 'wet' part of the machine and chips do fly under the shield. I am running two Adaptaflex IP54 rated 20 mm flexible conduits in this channel, but pulling them in took much ingenuity and messing about. The chassis sockets on the termination box have to be soldered in-situ, so to avoid soldering upside down in a confined space have minimum length tails to reach a table on which I could do the soldering, they then will be coiled up and put inside the box. Fortunately I'd made a dummy test plate before I drilled the box, so used this to keep things at the right spacing. |
