Gentlemen, I am a hobby machinist and completely new to CNC. I just recently purchased a 1994 Bridgeport EZ Track SX, 2-axis machine knowing that it had a problem with the control system. The person I purchased from said he thought it may have a bad motherboard. When I got the machine the motherboard, MIO400 board, VGA board and BMDC board had all been removed.
After reading many posts in this forum I checked the battery on the MB (386 SX-16/20/25 DNE)and found it to be bad. Grundig serial number calculator. I am remote mounting a battery pack as suggested in this forum. I am now at the point of re-installing the boards but since I am completely ignorant about the inner workings of computers, and my schematics don't give the specific information I need, I'm not sure if it makes a difference which ports are used to plug the BMDC, VGA and MIO400 boards into the MB.
Any help you can provide will be greatly appreciated. Also, if you know of any 'landmines' I need to avoid as I work through this, PLEASE let me know. Thanks very much. The boards identify themselves to the mother board. Plugging them in is a matter of convenience. Usually there is a small right angle bracket to hold the opposite end of the BMDC to the back of the electrical enclosure. Is the CMOS battery a Dallas real time clock?
In other words a IC type? Or is it a Nicad type made of 3 cells welded together with heat shrink around it?
If the Nicad type, it needs to be unsoldered as it will eventually leak and destroy the mother board. If you use an external battery, they typically come with a plug to plug into the mother board and a jumper is moved from internal to external battery.
The only landmine is that the older BMDC did not have a shroud around the ribbon connector in the center of the board. If this ribbon cable is plugged in wrong, it will smoke and melt. Gentlemen, Thank you both very much for your input.
George: The battery was a NiCad (3 cells shrink wrapped) I removed the battery and soldered two wires in it's place (making sure to mark polarity). I am remote mounting two battery packs wired in parallel (3-1.2V NiCad AA's in each pack). I plan to put batteries in only one pack at a time. The other is just for convienence at battery change-out time. Thanks for the warning about the ribbon cable on the BMDC board. I have not looked at it since reading your comments, so I'm hoping that it's direction is evident. Again, thanks for your help.
I Suspect that I'll probably be groveling for more help before I get this thing up and running. George, Thanks for the input concerning my battery replacement. I will check them weekly as you've suggested. Also, I got all the boards and cables replaced today. I'm pretty confident that everything is where it should be.
It will probably be a couple of weeks yet before I attempt to start this machine as I'm in the process of building a rotary phase converter. Thanks again for your help. Hi George, I last corresponded with you in January of this year about trying to start up a BP EZ Track SX that I had just purchased. As you can see by my last post to you, I had just replaced the MB CMOS battery per your recommendations. Also since the display screen on the pendant is bad, I connected an external monitor and keyboard to do the start-up.
Right after the battery replacement I attempted to start up the machine and immediately got smoke out of the control panel (never a good thing!). I tracked the burning back to the MIO 500 board for the floppy drive. I purchased and installed the replacement board but never got to try again until this morning (had to step away from this project for a few months). I have researched everything I can find on this forum about getting this machine up and running and have pretty much used the advice given by you and NC Cams (you both seem to be very knowledgeable on these machines).
