Planning - Bridgeport Interact 1 linuxCNC Retrofit

And it's in the garage and head is off! Disassembled as one unit. The way the unit separated I found that it was not necessary to disassemble the wiring harness from the control panels, because the centering disc kept the machine from shearing the wiring cables.

Andy,

Yes I used a 1 1/2 ton engine crane and 10k straps to remove the components.

I used a 6k pallet Jack and a 8k cable hoist to pull it into my garage. I bolted a 1/2 inch concrete wedge anchor into the concrete floor for a pulling point. I had to use the hoist (in the very back of my garage, centered in my garage) due to the fact I have a about a 4 foot 8degree grade into my garage from the driveway. So pushing it was not an option.

Here is how I attached my sling to the garage floor. I drilled a 1/2 hole into the metal bracket.

This mill was from a Tech School in Tennessee. Sat in a shop for 6 years before he got rid of it. Looking at the saddle i would say it should be a tight machine.

I would like to hook up my machine to single phase 220v to test out my amps/servo's, drive-train. What should I do before I hook my machine to power? I do not have 3 phase power and the spindle is disconnected. As far as I understand the spindle is the only part of the machine 3 phased.

I'm contemplating acquiring a 3phase converter for this machine, then purchase a VFD for it later.

Would I damage my machine by hooking it up to single phased 220v power? Something to disconnect or remove prior to? Or would it be best to have a 3ph converter first?

Thoughts? Comments? Suggestions?

I have been reasearching the iC-MQ EVAL MQ1D and iC-MB3 iCSY MB3U-I2C USB adapter. The adapter is expensive!

Andy, the encoders terminate in 9 pin male plugs. I'm considering the exe boxes at the moment.

Most of my connections to the TCN-151 controller was cut. Not much of a bad deal. Also one of my encoder cables were cut. I can just shorten and install to the servo, I have plenty of slack.

The T2 transformer is an auto-transformer from my understanding. In the wiring schematic it shows it as using 103 and 104 as a power source. L1,L2 So I believe this is a step up transformer because the required voltage going to my servo amps require 380v input. Is this accurate? Or am I misreading the schematic?

Andy,

Well good news. The autotransformer does step up voltage.

In accordance with the schematic I checked 0v line and my 380v line and received around 350v. My L2 (#112) is connected to 210v on the T2 transformer. (Was wired previously for 210 3ph).(I need to move it to the 220) I had to actuate 5FC relay manually to get the power to T2. I haven't figured out what signal to actuate it yet.

Now the bad news. I blew a resistor in my control cabinet upon first actuation of 5FC. (Scared the **** out of me!)

Attached is the resistor I'm currently trying to figure out what it goes to. I think power is heading toward my z axis limit switch wiring. (I had one disconnected and grounded) I think it was a 3R3 prior to me destroying it. But that is from memory.

I'm a child playing pilot in an Airbus here!



Alright. Traced it down to R7, #169 and #7. Guess I took out the z axis power resistor. Now to find a replacement. I think I found the short. I'm at fault. I had the wires hanging from the encoder box but failed to ensure one wasn't grounded. :doh:

Maybe someone should take this machine from me before I destroy it!

So now the question: where to get a replacement and when the drive amps are powered are the servos immediately powered? I'm pretty sure I tested that. But just incase it should not have happened.

Would this be a suitable replacement?
