Bridgeport Series I CNC, how to run it.
I finally brought that Series I CNC Bridgeport to my warehouse.
It does power up. http://igor.chudov.com/tmp/Bridgeport-Series-1/ It does not complain of anything, however, I was pressing various buttons and I could not get it to do anything, such as move in X, Y, and Z. I did take it out of E-Stop. I am wondering if anyone has a manual for it, or a simple instruction like "press this and then press that button" to just get it to move and move the spindle. Thanks i |

You may need to have air, and the lube pump switch needs to sense there is oil in the tank. Is this a BOSS? It may have blown or dirty fuse contacts in the motor drives. Jon |

: http://igor.chudov.com/tmp/Bridgeport-Series-1/ Man, Ig... is there really a market for stuff in that tuff of shape? Was it really, really, really cheap (like scrap weight value)? LLoyd |

Was it really, really, really cheap (like scrap weight value)? I paid not too much for it. One Chicago guy I know recently sold the same machine for $1,999. If I can figure this machine out a little bit, I can probably get that much, especially if I can explain the buyer how to convert it to PC based controls. Someone emailed me some instructions on getting it going in manual mode, I will try them tomorrow. As far as "tuff shape" goes, I think that this machine, as of now, has two known problems: 1) It is very dirty 2) It has a very obsolete control. I will see if it has other problems. I think that it has a potential to be a fun toy for someone, and to be retrofitted to EMC2 or Mach3 for under $1k cost. i |

The way mine was wired, and I kept it this way, the lube level switch is wired in series with E-Stop. Low oil means nothing is done. i |

Thanks I haven't run one of those in about 35 years but if I recally correctly, it needs to be put into "setup" mode in order for the jog buttons to be active. http://www.lowryindustries.com/BridgeportManuals.htm |

That is the stepper motor powered version - with an LSI-11 as a CPU. The view in the back shows the big three phase transformer, and below it three saturable reactors (Mag-Amps) which control the voltage to the stepper motors. A lower voltage (something like 50 V IIRC) when holding position or stepping slowly, and bumped up to 80 V when stepping fast. I'm not sure what the black things are above the three phase transformer. This is a somewhat newer one than mine. (I'm currently most of the way through fabricating a diagonal motor mount for a Y-axis servo, which is too long to fit where the stepper did -- nesting in a cavity cast in the knee. :-) It does not complain of anything, however, I was pressing various buttons and I could not get it to do anything, such as move in X, Y, and Z. I did take it out of E-Stop. I am wondering if anyone has a manual for it, or a simple instruction like "press this and then press that button" to just get it to move and move the spindle. First -- are all three axes off the limit switches? (The Z axis has three switches in a housing where the depth stop rod lived on a manual lathe of the same period -- top and bottom limit, and a "home" switch, while the X and Y axes have a single switch (lever-operated Microswitch which switches when the lever/roller is pressed in either direction). Now -- going to the photo of the control module Go to the block called "AXIS MOTION", and select a step size with the upper left switch, an axis with the switch to the right of it, then turn the "MOVE" switch to whether you want it to go + or -, and finally press in the "MOVE" switch (yes, it is a pushbutton as well as a direction selection switch). There is something else which you have to do as well. This is a newer one than mine, so I'm not sure. On mine, I had to open the door on the top of the computer chassis (may have a punched tape reader in there, or may have a blanking panel), and on mine there were switches on a 1U rack panel, one of which was a CPU reset switch. That had to be hit before anything else would work. That may be the START/(RESTART/CONTINUE) switch in the FUNCTION block on this one. This also is a rotary switch to select a mode, and a pushbutton to do what you've selected. And I think that the "MODE" switch needs to be in the "SETUP" mode (green, to match the background color on the motion control switches. Not sure whether the EDIT/RDI switch needs to be set and pushed or not on this one. At least here are some things to try. Mine had severe electronics Altzheimer's -- within 30 seconds after a reset, it would lock up again -- unless it was too hot in the shop to work without drowning everything in sweat. This was about fifteen years ago, and I started pulling the stepper motors and replacing them with servo motors back then -- and got hung up on the Y-axis motor mount -- until I finally got the ability to weld. I am now working my way towards making it usable again. Be sure to cycle the DeJur lubricator on the left side before you try moving axes. That is the thing at the bottom of: http://igor.chudov.com/tmp/Bridgeport-Series-1/Bridgeport-Series-1-0008.jpg.html Normally, you pull up on the mushroom on the left top -- but it sort of looks like it is stuck up right now. Make sure that the reservoir is full of Vactra No. 2. There is a level switch in the reservoir which may keep things from working if there is not enough oil in it. Yours has the pneumatics for the air motors to change the speed and to operate the spindle brake while you are changing tools. Mine never had those Good Luck, DoN. -- Remove oil spill source from e-mail Email: | Voice (all times): (703) 938-4564 (too) near Washington D.C. | http://www.d-and-d.com/dnichols/DoN.html --- Black Holes are where God is dividing by zero --- |
