  1. Re: What do you think about climate change/global warming?

    They do not produce zero emissions. A recent study in New Zealand which has an electricity grid with close to 100% renewable electricity showed 60% reduction in carbon emissions in a cradle to grave...
  2. Re: Emco F3 conversion - electronics and controller

    I've got the basic machine working. However I'm still fettling with the controls as I want a mill that I can run semi-manually. I.e. buttons to step in the X-Y-Z axes at various speeds. The CNC720...
  3. Re: Emco F3 conversion - electronics and controller

    I've got a new version of the control software to install to see if it fixes the mapping (of buttons) issue. I'll have a go this coming weekend.
  4. Re: Emco F3 conversion - electronics and controller

    Some more progress. I was waiting for a bench power supply to arrive so I could bench test the controller before I commit to ripping out the existing control gear and replacing it with this new...
  5. Re: Emco F3 conversion - electronics and controller

    I've powered up the 24v and 48v sections of the enclosure.

    I'm getting a limits switch fault light come on - which makes sense as I have not yet fitted any limit switches. I'll need to provide a...
  6. Re: Emco F3 conversion - electronics and controller

    I'm having trouble with the setup of the Eding auxiliary input board. The configuration software keeps losing mapping of physical inputs to the underlying software commands.

    I have raised a...
  7. Re: Emco F3 conversion - electronics and controller

    Panel mounted, 6 pin, male gender. I have found some now from a different brand :)

    Re: Emco F3 mill conversion

    I'll need to make a guide piece so I can centre the pilot drill in the existing hole in the casting. That's been put on hold while I get the control enclosure/wiring progressed.
  9. Re: Emco F3 conversion - electronics and controller

    So those parts now show a shipping date of 8 May. And Element14/Farnell show them shipping in August, so time to choose a different supplier.

    In the interim I've mainly completed the internal...
  10. Re: Emco F3 conversion - electronics and controller

    Eding have investigated and it appears that the display on the PC is not updating, a new version of the software will remedy that.

    I've been doing more wiring while awaiting some XLR 6 pin sockets...
  11. Re: Emco F3 conversion - electronics and controller

    I'm about half way through wiring up the control box. It's really quite time consuming, although I'm work slowly and methodically as I do not want any mistakes. I've almost finished the power...

    Re: Are OMC StepperOnline online ?

    Hmmm, the email I'd sent asking if I could add another item to an unshipped order had scrambled their process. They were waiting for me to pay, but they had not sent the invoice for the additional...

    Re: Emco F3 mill conversion

    Thanks Jim, I'll probably be giving this a go in the next week or so. I thought I should ask the question in case I had to order in a carbide holesaw, so nice to know I can try with an ordinary bi...

    Re: Emco F3 mill conversion

    Can a Bosch bi metal holesaw cut through cast iron or do I need a carbide tipped holesaw ?
  15. Re: Emco F3 conversion - electronics and controller

    And here's the enclosure painted, actual colour has more orange in the colour than is showing on my monitor. Almost time to start installing the components inside but I'll give it a day or so to...
  16. Re: Emco F3 conversion - electronics and controller

    I got a first coat of the red paint onto the enclosure and door this morning. This cannot be over-coated for 12 hours so I'll try to get the second coat done tomorrow - weather dependent as I don't...
  17. Re: Emco F3 conversion - electronics and controller

    Eding have come back to me, so we're going to try a few configurations. In the interim I have spray primed the enclosure and door. I'm using a two pack urethane acrylic top coat in RAL3020, over an...
  18. Re: Emco F3 conversion - electronics and controller

    I hooked these switches up on the test bench to the EdingCNC UIO-10 accessory board to check how the switching works with the software.

    I encountered two problems: the first is that the input for...
  19. Re: Emco F3 conversion - electronics and controller

    More progress on the enclosure. Way back 3 years ago when I started this conversion a comment was made that the mechanical parts would be the hardest, with the electronics being straight forward....
  20. Re: Emco F3 conversion - electronics and controller

    So, I mounted the latch and the door microswitch this morning, then life got in the way. Hopefully tomorrow will see the backplate installed (and some more photos)
  21. Re: Emco F3 conversion - electronics and controller

    Got some cabinet hinges yesterday. I've bolted one leaf to the flange at the back of the cabinet and cut the other leaf to fit the door and tacked into place (whoops - a bit much current on these...
  22. Re: Emco F3 conversion - electronics and controller

    The parts arrived and easily snap into the 3 position rotary switch. I've fitted a NO switch block at each end, and a NC in the centre. This gives me the 3 settings for STEP0001, STEP001 and STEP01....

    Are OMC StepperOnline online ?

    I've bought stuff from this crowd before and they have been reliable.

    I ordered some additional cable and couplings on 4th Jan, received a Fedex shipping email on 7th Jan showing a shipping...
  24. Re: Emco F3 conversion - electronics and controller

    And here it is welded up. Well technically not welded as I TIG brazed it with silicon bronze.
    And I've done the cutout for the control panel plate, which was done after welding to ensure the box...
  25. Re: Emco F3 conversion - electronics and controller

    I collected the sheet metal for the enclosure yesterday. The folding is very good apart from a folded tab at the front base which is preventing the front panel from fitting flush. I'll cut it off...

    Custom Way Covers

    I'm looking to make (or have made) something to cover the Z axis on my Emco F3.

    The width is around 185mm, the depth of the dovetail is approx 15mm. Z travel is 350mm, and there would be at least...
  27. Re: Emco F3 conversion - electronics and controller

    Another possible change to the control panel is to emulate the behaviour of the Emco FB3 power feeds in X and Y axes:

    when the spindle is off the X+/X-/Y+/Y- buttons are only active when pressed...
  28. Re: Emco F3 conversion - electronics and controller

    The control panel has evolved a little since post #2.
    I've added a button to control the work light, a Home All button, and a warning light for the fault alarm from the stepper driver.
    The jog...
  29. Re: Emco F3 conversion - electronics and controller

    Sheet metal supplier is running a little slow, so I've down the layouts for the internals of the control enclosure. I have not modelled it in 3D, but essentially there are 4 planes with components:...
  30. Re: Emco F3 conversion - electronics and controller

    I've found an accessory part on the manufacturer website M22-XW. From what I can see these snap into the actuator plungers and enable operation of a switch block in the centre position. I will order...
