Wow! That solved my problem ... thank you! Good note on doing a G52 Z0 after the operation! Its critical to remove the G52 offset before proceeding the next machining operation.

Hello all ... I am engraving, using command L9201, on some work-pieces. The program that I am using / writing utilizes user-input variables based on measurements that the operator takes on the...
Thanks for the response. The problem, we found out, was just as you described. We had the machining/approach switch in the 'machining' position ... it evidently needs to be in 'approach' to execute...
Hello...I've recently gotten a late 90's Nardini FastTrace w fixed spindle speeds. We've been using it as a manual lathe for a couple of months w great results. Our current problem concerns running...
Nice looking install!
Regarding the Bosch drives, I have the following document that I got from Bosch-Rexroth in their office somewhere in North Carolina. There was a gentlemen there I spoke to...
I noticed the same phenomenon, specifically that the X, Y, & Z axis motors are enabled all the time, but the A-axis motor only enables when a move is called ... thus using some sort of brake...
Great Andrew! I'm delighted. Post some pictures sometime ... I'd like to see it.
Hi ... I've been looking at upgrading to a nice, used CNC flat-bed/engine lathe, preferably with a turret tool changer. My primary need would be some hard-turning of some contoured shafts - size...
Hello all ... I'm in the market for a good, used CNC job-shop (flat bed or engine) lathe and have been looking at Bridgeport Romis with the turret tool changers. My primary job would be some hard...
Hi Andrew ... trying to send you a private message, it says your account won't accept PM's ...
Hi guys ... I just posted a new thread outlining the results of my journey through making a functional 4th axis for the Interact. I've been delaying making a post about it as I've been using for a...
Hi … I wanted to share that I’ve succeeded in building a 4th axis for my Bridgeport Series I Interact. I’ve been using it for about 6-months now without any problems – primarily as an indexer, but...
Hi Ludde ... regarding your cable questions, go to the following thread here on CNCZone ... there is a write-up describing cable pin-outs:
...
Anyone have a Heidenhain ERO 115 125 encoder for parting out? This is from a Bridgeport Interact with Heidenhain 151B with SEM servo motors ...
Yes, I've confirmed connections by "ringing" (checking continuity) with a multi-meter, pin-to-pin and ensuring there is no cross-talk between pins. I have access to oscilloscopes, but I had hoped to...
Al,
No to both of your questions. Without my extension cable, upon seeing the signal from the home switch, it will behave as you describe finding its zero without trouble. However, with the...
Al ... your message encourages me! Thank you. I have wired the extension cable, pin-to-pin:
1 - 1
2 - 2
3 - 3
4 - 4
5 - 5
6 - 6
7 - 7
8 - 8
Has anyone repaired or replaced a Heidenhain encoder cable? Specifically, my encoder is an ERO 115 125.
Background: In a separate post, I've been outlining and discussing creating a 4th axis...
Alright ... I'm super frustrated again. My latest task has been to build a jumper / internal-extension cable for the encoder, about 3-1/2 feet long, with a 9-pin Heidenhain female bulkhead connector...
George,
Thank you for the reply. Just knowing that the end-play should be zero, or very near, is good information.
Out of curiosity, do ABEC 7/9 rating seem appropriate for bearings in this...
Regarding machine parameters, I'm attaching a short document with the 151B machine parameter definitions. This might make it easier for you to corelate your parameters with 151B's ...
Hello all,
What end-play / compliance should one see on the ball-screw of a Bridgeport Series I Interact?
Some specifics, I purchased my Interact about a year ago and have been using it for...
I too have a Series I Interact, though with a 151B controller. Attached are my parameters, known good for my machine. Also attached is a scan of Bridgeport's original paperwork with machine...
Well ... I finished making and installing a bracket for relocating the ERO-115-125 encoder and stepping it up by 8/5 such that it is now providing 200-pulses per revolution of the motor. Attached is...
Fantastic! I'm so glad it was helpful. It sure took a long time to figure out ...
Hi...I need at least one Heidenhain 115 200 encoder that goes on the end of an SEM motor (MT30R4-58 or similar). Anybody have any?
Thanks!
The 125 means, I believe, 125 lines or pulses per revolution. My axis moves 144-deg for a control of 90-deg. That's 8/5 exactly. So I think I need an encoder with 8/5's the pulses per revolution. ...
Ok...for comparison how many lines do the standard encoders have? I believe that mine are ERO 115-125 encoders.
Gus - I agree that there should be some sort of proportional control on any P - I - D (proportional - integral - derivative) controller. MP28 - 31 is the integral values for each axis, and MP 32 -...
Hello all ... I finally finished building a 4th axis for my Bridgeport Series I Interact w/ Heidenhain 151B controller using an extra SEM servo motor and encoder (same as the X, Y, and Z axes). All...
