Thinking of getting a CNC mill, tell me about the bridgeport series 1 interacts

Steve,

The TNC355 is a good control - basically a TNC155 implemented physically in a different way. I have one controlling my Beaver Partsmaster and it's never missed a beat.

I would not be surprised if the parameters were not in a pocket in the back of the machine - they usually are. If not then the 412 H is not uncommon, you should be able to blag some off another user via the web. Then all you need to set up specifically to your machine, is the exact tool changer location, and the ball screw error and backlash mapping

(Heidenhain in the UK are very helpful, and no doubt your 'in country' Heidenhain people are the same - they should be able to point you to a source)

Back up batteries (3 x Duracell MN1500) need changing every 12 months - it has to be done with the power on - changed mine last week !)

Andrew,

Thanks. I opened up every cabinet looking for the parameters print off. One of the manuals even said where the parameters are stored. No luck.

I have just found a hopefully excellent video on youtube of how to do some simple things on the control:



I'll head back over to see the machine early next week and see if I can get any where. Do you have any idea whereabouts in the different cabinets those 3 x Duracell MN1500 batteries are? I did not see any. I saw a single AA sized battery soldered in to the circuit one of the cabinets.


Are the parts for these controls worth anything?

Thanks,
Steve

Steve,

On my TNC151B, the batteries are in a front-panel-mounted cylindrical holder, all that's visible (from memory) is a screw cap about the size of a 2p piece - will take a photo of it in the morning.

Hi,

Forgot to ask, what does the "H" stand for? the model number is "INT.412H". I understand the X variant has more spindle hp. Aparently a 10k rpm spindle was an option.

Thanks,
Steve

The TNC355 logic crate has a hinge down part (clips at the top) that folds down revealing a 3 cell battery box
