No you can not do that, we have told you many times,you can not jumper L1 to L3, as you had it before you can't make 3 hot legs form 230v single phase

So what you are saying you wired it incorrect from what we said for you to do in other posts

I thought you where saying the main input fuse had blown because it was 5amp but this is not the case

Ok I just looked at the schematic you supplied, so it seems you did not wire it correct as it should of been, you tried to take a short cut, which you can not do

CB2 is wired to 1L1 & 1L2 this is the 5 amp circuit Transformer feed

CB3 should be wired 1L2 & 1L1 This is the 20 amp circuit Transformer feed, ( this is were you messed up )

[dbtoutfit]

Yes.
Look in the images before that i attached to one of the last posts. I shorted T2 second leg to T1 leg after coming thru the fuse.
both transformers were pulling thru a 5a fuse.
I will send an image of what I plan to do before i power it up. I just picked up some new fuses headed back to the house.

Trust me the last thing I am trying to do is "not" what I was told.

I appreciate all the help and I am all ears to how I should be doing this.

Let me know what you think. I wont fire it up till I get confirmation.

Yes the first photo was wired incorrect, the second photo is correct, but should be connected to the L1 line direct, the third Photo with the jumper should never been done, L3 should not be connected at all

Ok. Now back to the X axis issue. Cant move the X axis at all. Pressing the jog +or- for more than 3 seconds causes the drives to kick off. Tabke never moves a micron. Chrcked the limit switch works fine and MNT page shows it click on when i press it.

Can you take the motor off, & see if it will run without being attached to the Xaxes

Are the Y & Z working

There may be some more wiring needed

[dbtoutfit]

Tried it again. Placed my hand on the table. I can feel the motor when i press +/- jog but it prob doesnt move .001 or 2. Now it says "Axis drive overload."

Not good.

[dbtoutfit]

Going to take the motor off now . Yes the Z and Y home and jog fine.

Measure the voltage going into the all three axes Drives

[dbtoutfit]

Is it just me or does it look like from the schematic the x axes is powered from the vfd?

[mactec54]

dbtoutfit

No not at all the 3 Drives are powered by the #2 Transformer you should have around 92v ac into the Drives from the transformer

The first Transformer powers the computer & low voltage supplies

The VFD is powered by the L1 to ( R ) & L2 to ( S ) L3 if used to ( T )

You need to do some power measurements

Another check you can do is, remove the covers on the x axes motor, turn it by hand, you will be able to see the encoder reading moving on the screen

I started to check power and bumped the two motor wires (135&136) and the fell out of the terminal.
I hooked them backup and tightened the wires down and powered the machine up.
When I hit 7 it kicks the drives on and back off.
I then unhooked the red and black wires (135&136), restart, hit 7 and the drives enable and VFD comes up.

My first thought is either I have red and black swapped or there's a short basically somewhere.

When I went to reinstall the wires they were twisted like it was suppose to be reversed from the schematic. When I installed them I put them back in based of the schematic and how Y axis card wires were installed on it.

Thoughts??

Wired the black to red (backwards from the schematic) Wala! X moved and homed no problem.

Bottom line, loose wire.

Now go & check every terminal that has screws holding/clamping wires, if there is one loose there will be others,you got lucky, as arcing from loose screws can damage control circuits, one board in which you have been closely connected to, the AUF board if damaged are very hard to find,a replacement for, we have 2 left but will not be selling them

Once you homed the machine did you run the spindle???

You still need to check all the voltages to see that they are correct

Just got a 26gl 5hp compressor from a good friend. Looks like my two little pumps couldnt keep the air up to even get it spinning. Work on that tomorrow. Thanks for all you guys help.

[dbtoutfit]

Got the Air going, tested spindle 200-6000rpms.
Nest, figuring out how to load tools in carousel.

After these machines set for a while is it kinda hard to get the tool up in the spindle?
It feels like after about 5-6 trys its getting easier.

I need Maint Doc on this machine to make sure everything is greased and lubed.
Any pointers from you guys that own this machine what I need to start checking before I start making my first chips?

Eric

You will need to check the lub pump to see that it has power,& is working, you also may need to remove the draw bar in the spindle, sounds like it is not working correctly, you may have to replace the Belleville washers, this may be the part number for them from McMaster Carr 96445K295 you need like 120 to do the job, take note of how they are stacked, this is important to get right

For the Lub oil Mobil Vactra #2, there are other Brand name oils you can use like Shell Etc they all have way oil, take some covers off to see that the Ballscrews & linear Bearings are getting oil, they don't last long if they are not lubed
