Re: Fixed steady TDS1/1 GB

Piotr, You have roller guides shown, consider making guides with bronze tips as well or instead of the roller ones. I have seen discussions about the pros and cons of each online but it's not something I have looked at recently but you may want to look at it if you haven't already. Both the fixed an...

Re: Another Communication problem

Wardy,

Have a read of this recent thread http://www.denfordata.com/bb/viewtopic.php?f=40&p=23863 . If your control board has the NiMH battery it may be the same issue of it leaking and causing comms issues.

Re: Mirac PC connection issues

I think I was wrong to say it is a NiCd, it seems more likely to be a NiMH. The battery markings say 2.4V 150mAh but no battery type on mine visible and the only ones that I saw that matched the design were NiMH from a search. Wiki lists the common electrolyte as potassium hydroxide so fairly corros...

Re: Mirac PC connection issues

Good to hear it's working again. I need to replace the battery on my board as it is a little crusty but I'm not actually using it as I'm converting to LinuxCNC and a BOB. Better you spend on a new NiCd cell and replace the one on the board with a new one, I expect RS and others sell them. It may be ...

Re: Mirac PC connection issues

I think this may be a similar board to the Triac PC I have and there is a NiCd battery near the comms area which is prone to leak and the crud may be the result of that and effecting the signals in the area. Can you post a pic. Cleaning the area carefully with distilled or deoinised water may help r...

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...

Steven, Good to hear you have the coms working now which should make your life much easier regarding being able to enter and save programs to a PC and send them back to the mill later.

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.

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....
