I have a Bridgeport Interact 1, mk 2 mill with the Heidenhain TNC 155 control that
I use for prototype & short run jobs. I love the controls ease of programming but the servo motors & drives are...

I had a friend with a similar machine tell me the same story. It turned out to be a bad drive on his as well. The question now is how to determine which drive is faulty. I imagine these original...

A couple of weeks ago we rebuilt the entire head on our explorer 1. On Monday a screw came out of the brake actuator and activated the brake while the spindle was running and the operator was 2...

Hi all!

Been awhile since I have been here. I bought a Haas VF1 at auction and it arrived last week. After hook ink up and getting activation code from Haas I am getting an under volt alarm and a...

Thanks Mike

I Changed the incoming voltage range and the alarm went away.

Hi All

Just got in my 2001 SL-20 with servo 300 bar-feed. After power up I got this alarm "Low Voltage Alarm" the description in the control Say's this alarm appears when the control detects an...

I have not been on the zone for a while so missed this, The Siemens control uses the G97 to set the direct RPM and you must program a G96 SXXX (surface per minute) on a separate line every...

Sorry it has taken so long for the pictures I have been very busy. If any one is interested I still have this machine.

You are talking to 2 different Mark's, I found these files on another forum and posted here. I am still trying to get my machine running.

After replacing the burnt board and installing the...

A simple way to measure your top plate. Put a 1/4 collet in the spindle & close on a #3 center drill then move an empty space on turret under the center drill and measure with a ruler.

The file you have is for a CHNC2/FANUC 10.

Here is the commisoning data for CHNC1/SIEMENS 810T

Mike

I have the same machine as you and have lost all the commissioning data due to a board shorting out.

Could I trouble you to download A copy of yours and e-mail to me ?

Thanks Mike

I found several of the exact board that I need on EBAY this morning. They range from $200 to $400 for used and $700 to $800 for NOS.

I only have hard copies of the manuals so...

I know this post is very old but I got the magic smoke from my control this morning nd was looking for parts.

I have not gotten my burned board out yet so do not have a part number but Do you...

The Interact 1 mk 2 has a magnetic actuated brake. There is a large electro-magnet coil on the top of the motor shaft. The switch you refereed to is an om/off for Manuel mode operation of the brake....

OK I checked the resistance of all three TACH's, X & Y were the same and Z was double that. Swapping drive boards made no change I still get the same alarm. I do not have a copy of program B3T.exe...

Sorry about the pressure George. But when the less gifted gets clear, understandable and correct information from one source we tend to gravitate toward that source when trouble arises.

I will...

Sorry it has been so long since my last post but there never seems to be enough time in my days to complete orders and repair machines.

So after weeks of send boards back & forth with EMI (they...

Is any one interested in purchasing a retrofit candidate, I have a Bridgeport Interact 1 Mk2 and the spindle drive died last year. Since then it has been donating it's parts to keep it's two brothers...

The DX-32 is a very good control for a job shop, using MACROS, LOOPS, & CYCLES you can program most 2-1/2D parts at the machine in very little time.
But it has a very annoying start procedure. On...

I now know why the Bridgeport company no longer exists, They hired morons that designed their BMDC boards backward then when the greedy CEO's didn't want to pay to redesign it they said "Just turn...

Today I tried your suggestion, I jumped the 24 vdc to the axis enable ( pin 1 on CR1) nothing happened but when I push in the ESTOP the drift stops and if I jumper the 2 pins again the drives will...

George

I was able to get back to this today. I can see no movement in the CR1 relay when I push in the Estop switch but the drift does stop. I was able to find 5 volts at the resistor on the...

Yes I am finally learning which boards do what. I am glad to see I am understanding this right. I will check in the morning to see if CR1 is actually working.

Now that I think back on it, the...

Thanks George

I have wiring diagram #1943101 rev.H

I believe that this is a 24 volt system. I have a steady 26 volts at AUF plug JP4-2a (wire 186) and AUXBOB plug JP6-2a (wire 185) These 2...

I was able to get back to this machine today.

George
I could not find a component that was labeled L on the BMDC but I did not find any damaged components. I had replaced the battery you spoke...

Thanks George
Am I correct in assuming that L1 & L2 are good if there is no visible damage and have continuity on both.
