    Re: Denford MicroMill 2000 rebuild

    Yes, it's an engineering polymer. There is no ground or earth required on the low voltage control boards – each has a 24V input with no support for grounding. All the high voltage equipment has been...

    Re: Denford MicroMill 2000 rebuild

    A friend of mine laser cut a panel that I can attach the boards to. I don't have a lot of spare time, but I test-fitted it to the mill case today. All fits great, so in the oddments of time that I...

    Re: Denford MicroMill 2000 rebuild

    Thank you. I called Denford before your replied and they confirmed exactly what you said. A chap named Jay Summet is also helping me out (being by default the Denford go-to man from his excellent...

    Re: Denford MicroMill 2000 rebuild

    No problem DB, I'll just finalise what I do and don't need first then you're free to make me an offer on the pile.

    Having thought about placement of parts I still need a bit more room than what is...

    Denford MicroMill 2000 rebuild

    I've been able to snatch a few minutes here and there to almost completely strip the interior of the Denford MicroMill ready for installing new parts. There are a lot of relays used in this machine,...

    Re: My name is Steve and I'm a manufacturer

    My designer uses SW so I just have to get another license. I should be able to pick it up to do simple tasks (relatively speaking!) like making tool inserts.

    Re: Requirements for rebuild

    Thank for the help. I have the stepper controller and the Acorn on their way. I just have to get myself a PC to run it, and being a Mac person for just about the whole of my life, this is going to be...

    Re: Requirements for rebuild

    I may need to use the relays relating to the speed controller and spindle, but apart from that I can strip everything else out entirely. If anyone is interested in the parts please let me know.

    I forgot to mention red lines are power and blue are control. Also, the grey box are parts I may replace in the near future. I need a higher rpm spindle to do what I need. If anyone has any...

    Re: Cheaper alternative to Gecko G540

    Thank you LeeWay, I ended up buying a slightly used MX3660 for about half the price of a G540. I only need 3 drivers so it was perfect.

    Cheaper alternative to Gecko G540

    I have 3.1A stepper motors and I'm finding the Gecko G540 a bit pricey to buy and get shipped over to the UK (the UK supplier is even more expensive!). Is there an alternative for a budget build, but...

    Re: Requirements for rebuild

    Thanks Mactec

    This is only a temporary machine so I don't want to spend too much on it, but if I get it working to a reasonable accuracy I could keep it for smaller jobs.

    Re: Requirements for rebuild

    Thanks. Is there not a one board solution to this? It seems a bit nuts to me as a newcomer, that a drive board (which is VERY simple compared to a controller) is not included? I can't work out why...

    Re: Requirements for rebuild

    Thanks John.

    As far as the mill is concerned, I'm going to use the motors connected to it for now, as well as the spindle, but I will need to upgrade the spindle to a faster one pretty quickly. If...

    Re: My name is Steve and I'm a manufacturer

    Thank you Andrew.
