You will be amazed how much torque those little motors have. I have recently converted some 350w yaskawa servos to DMM-Tech drives by installing DMM encoders. They are incredible. Let me know how it...

BrendaEM,

The 4 optos you are looking at are for output, not input. You want to look at the white TLP620-4 opto bank to the right of the 4 optos. These optos use SIL resistor banks and will be...

BrendaEM,

Can you post the model number of the drives you are using?

If the drive has isolated inputs looking for 24V, the optos might work with a lower voltage. You would have to look up the...

Hello BrendaEM,

What is the model number at the top of the face of the drive? I know they made a 100V single phase version of these that were slightly different then then the ones I had. I believe...

Hello BrendaEM,

Im sorry, But I no longer have a means to set up a working system to video. These drives use an scr rectifier with phase detection to control bus voltage in the drive. Without true...

The router has been progressing over the last week. Slower then I had hoped, but Its coming along.

As I said before, the size of the machine was determined by the rails I had on hand and the...

This build is something I wanted to do to try and put some of the machine parts I have to use. A few years ago I salvaged a few truck loads of parts off of 3 industrial pick and place machines. (2...

Another great video!

Where did you get the material for the bellows you used?

Well its been 2 weeks, Time for another update.

I have mostly been finishing the design and testing components.

I built myself a vacuum table to test the ability of the 1.1HP 3p regenerative...

Well its been another week and some more progress.

We have decided that we will be going with the DMM-Tech servos. After talking with them, we have decided that 400W motors on the X and Y axis...

Initially, when the machine was smaller and lighter duty, we were going to use large steppers, But now we are looking at DMM-Tech servos.

I am looking at a 400W servo for the X and Y and a 300W...

Well I was hoping to have more of an update so I head off till today, but still not as mush as I would like.

On Friday I started the mount for the far end of the X screw. I only had an hour to...

The bracing was just going to be a spine down the side. Something like U channel or just a piece of 3/4 x 2" to form a T.

She's pretty easy going with things like this. Using the sink for a little while doesn't cause a problem. And it gets me to do the dish's :)




I assume your looking at aluminum? Originally I...

Hello All,

Thought I would start a thread of my first router build. I have converted 2 mills before and have 4 machines in total. Bridgeport, X2 Mill, Jet Mill, and Emco Maximat Super11 Lathe.
...

Ray,

I do already have the manual. The motors that I have are the USESEM-03 for the Y, and USASEM-08 for the X and Z. I have a VFD that will run the spindle whatever it ends up being from single...

Hey Ray,

I checked out that rotart converter and gave them a call. They say it produces 120 degree phases and withing 5% voltage regulation. Im thinking I will try it and see how it works. It will...

I'm told by the guy running these machines that the drives and servos came from of, they don't like rotary converters or dirty power at all.

Another thing I was thinking about this AM was trying...

Hello Matt,

I am slightly worried about the Y axis of the gantry. I halve already found some rail upgrades for both axis's. My plan is to only rarely use the machine for milling steel. It will...

Thanks KriegKuts! The parts were just a right place right time kind of thing. As for A height, 36" was just a goal. I always have things I am working on that would be easier if I could just fit it on...

Hello Everyone,

I have had this project in the back of my mind for a few years now. Ive been collecting parts and planing my moves. I think it is...

Ercdave,

I think I can help as I have done this. I was successful in connecting 2 of the CACR-PR servo packs to Mach3. Here is a video if you havnt seen it already. YouTube - Yaskawa...

Shane123,

Thank You. That was the answer I was looking for. I was thinking like .003 to .004 would be good, but wasnt sure.

I am working on a simple shaft coupler for connecting a large electric motor to another shaft. I need to bore the coupler to slide nicely over the motor shaft. My problem is I do not have the motor...

If you look on http://www.tormach.com/Product_PCNC_maint.html, about half way down there is a replacement bt-30 taper spindle cartridge.

OK! I have been really busy the past 2 weeks, but here is what has happened.

I picked up the column and new mount from my friend Saturday the 12th. He had mounted the block inside the column and...

I have been using Solidworks 2007 for 3 years now and have had Visual Mill 6 (3 axis) for 1.5. I have to say that they work well together even without the direct Solidworks plugin.

I would...

Yes, Im sure they were expensive. They came from a machine made by Sanyo. A 4785 Chip-shooter. They are not that old. The machines were from the late 90's and went for about $800K new!! They are a...

I have a few of these of different sizes that I got out of a circuit board machining called a chip shooter. They are zero backlash with a lot of flexibility. I am looking for a place to buy some...

Well I finally got around to getting this done.

I have a friend that is making the mount for me. I just havent had time to do it, and my big knee mill is out of wack with excessive backlash in...
