Re: Micro Router 2nd Hand

Searching for "Device Driver Call Failed" turns up this thread on the BB http://www.denfordata.com/bb/viewtopic.php?t=1650 which indicates it may be a hardware issue. As that specific error message got one match it would seem to be a Denford software error message rather than Windows.

Re: Micro Router 2nd Hand

You might want to try a different USB lead, IIRC it was someone else here on the BB that had USB comms issues occasionally and it turned out to be a duff lead.

Re: Micro Router 2nd Hand

I don't know the cover but you could try using some toothpaste and water on a soft cloth or paper towel to polish it to see if the discolouration can be cleaned up. It's what I use to clean the rear plastic window in a convertible top and the plastic head lamp covers on my VW Passat. Cheap, quick to...

Re: Novaturn ATC blowing fuse on startup

Regarding your question about why more current would flow when the motor is stalled. I'm assuming this is a permanent magnet DC motor like in my Orac tool changer, when the motor rotates as the windings are moving through the magnetic field they generate a voltage which opposes the applied voltage s...

Re: translation gear set for 280 synchro to cut imperialon metric lathe

I wonder if something like the electronic lead screw could be a viable alternative http://www.autoartisans.com/ELS/ . Searching for 'electronic lead screw' also now turns up at least one other similar project. The ELS project has been around for some years now and I would expect it to be good and so...

Re: ZeroCentre Fanuc alarm 960

I don't know this machine or electronics but for an initial check I would look out for any socketed chips and after grounding yourself I would prise the chips out and press them back in. Classic failure in old electronics with tinned leads is oxide film formation causing degradation of the signals a...

Re: Tripping rcbo and coms issue

I saw your problem and was wondering if the socket you tested the spindle motor with a kettle lead was on a different supply RCD to the one that tripped or the same. The reason I ask is that RCDs can go bad and trip with some loads, I experienced it with my TIG welder where when switched it on it wo...

Re: Easimill 3 conversion preferences

IIRC in Programs->Utilities you should find the program Hyperterminal, run that and open the com port your RS232 lead is connected to. Configure the port as appropriate to suit the mill coms settings ie baud rate, stop bits, parity and handshaking and then if all is good when you send a program from...

Re: Serial Micromill stopped connecting

I have a similar looking board from a Triac and over time the NiCd battery can leak and is near the RS232 connection so if it has it could be effecting the signals. Replacing the battery and cleaning any residues with distilled or deionised water may help, I'm not even sure if it's required as I hav...

Not trying to put off a conversion as that may be beneficial but I was wondering what you have tried regarding the RS232 comms. I know from personal experience as a programmer for 20 years that RS232 causes more trouble than most anything else and seems to have caused some on the BB to lose the will...

Re: My Novamill won't run

Tony, The logic supply will be the 5V supply to the control card, +12V and -12V may be required by the RS232 comms circuitry. The main control card with the 7 segment display looks like that in the Triac but the output board it plugs into is different and has drivers for some of the output devices, ...

Re: My Novamill won't run

I'm thinking that those connectors you're seeing 21V at may be connected to the relays and maybe some other items as IIRC like in my Triac one side of the relays is at 24V and is powered when the open collector drivers on the control card are energised to pull the other side of the relays to ground....

Re: electrical power control box to machine

The data sheet is fairly lacking in detail about the outputs, page 5 gave me hope that the output levels could be changed to 12V but all else indicated to me step/dir at 0 and 5V. The levels would need to be confirmed with the supplier or the output chips identified. The included picture shows marki...

The step and direction signals are internally pulled up to 12V within the Parker cards and so touching the wire to the signal ground would simulate a step signal, connecting the...
