Very nice! Love the fact that you convinced the wife to let you bring it inside. Wish I could do that! How many HP was the 3 phase motor you bought? Do you like the VFD?

I found some load ratings, but can't make sense of them.

The 16 mm states the following

Basic Load Rating:
Dyn. CN - 774
Stat. CON - 1180

For the 20mm

You make a good point, I should reveal more about my project.

Each axis will be 60", which is the length of the rail. The base will be made of 4x4" .25" wall steel tube for the legs, with 2x2"...

I have always been set on 20mm supported rails for my future wood router. I want to have the least amount of fuss, and a bolt together setup is appealing.

I basically planned on getting the...

At the local community college, we have classes for sewing and woodworking. You basically have an instructor, there's limited involvement, mostly to help if you have a question. But they basically...

I know it's been awhile, but time for an update.

I've actually been following the main polymer concrete thread this whole time, as well as other CNC related projects, but I figured it was time...

In my experience, when that has happened to me, it's because my steps per inch are off. Or backlash is present. But I'd lean towards SPI being off.

I setup a dial indicator and make movements,...

Very interesting indeed! I have to admire your ingenuity. I'm sure you'll be quite pleased with it when you're done. Is this your first CNC router? What do you plan on using it for?

Looks like an interesting design. I've never seen something like the z axis you have setup. Only thing I could point out was how to you plan on lifting/moving the z axis? Some sort of mechnism on...

Well, I fixed it. It turns out it was more an issue with the Xylotek board. So I connected wires from the xylotek BOB board to my CNC4PC BOB, and that boosted the signal. So now it works just...

Well, I seemed to have figured it out in part. I used by breakout board instead, and just wired it up like normal, and it worked great. So for whatever reason, the BOB on the side of the xylotek...

I'm getting really frustrated now! Not saying it's anyone by my own fault, but I just can't figure this out. First, I'm not new to Mach, or Gecko. I have a thread in the Gecko forum, but have...

Thanks for the diagram. I had actually seen it on the thread with your own issues.

Mariss, I tried what you said, and sure enough the 5 volts steps the motors as I tap it. I never really...

Thanks for the replies! Yes, I am getting holding torque, which in fact means it's doing what it's supposed to be doing. That makes it all the more frustrating! :) I figure it has something to do...

So, I bought a 203V to start my way on having a whole 4 axis set. I have a xylotex board, which is pretty good until you look at it wrong and something blows. Not it's fault, just very sensitive to...

Thanks for the reply Gerry! I see what you're talking about in the documentation. Should have read that more carefully. :) it looks like that card is pretty robust and a good deal. Plus, I'm...

I have found all kinds of research on how to setup a relay board and router, but not much on which ones I should get.

I have a CNC4PC breakout board, and am looking to get one of their Relay...

Just to add something... I have put two 80lb gas springs underneath my head. I need to fasten them, but they help tremendously! Since this is non cnc, the backlash is irrelevant. You can definetly...

Ah, I see. So for the unit to maintain RPM, it would need some sort of feedback? Do all DC controllers work like this?

So I would basically want to vary the pot on this controller when the...

I had a general question about this controller. I don't need it for CNC, just to control 130V dc motor and have variable speed capabilities. I'm actually going to use it for a motor to make a power...

Thanks! That makes a bit more sense. I still have a ways to go understanding all about motors though.

I know that DC motors will increase in RPM, as you increase the voltage. I'm trying to figure out, based on all the DC motors I have and have taken apart, is what determines if one develops full RPM...

Thanks! That makes a bit more sense. I'll definetly keep an eye out then. I haven't tried cutting threads yet, but I'll soon see if I really need to make the investment or not.

I have a Logan lathe model 922. It's about a 11 or 12" swing, and 48" bed. It has all the gears, and the power feed and screw cutting levers all work.

The problem is that it doesn't have a...

Thanks for the advice. Luckily I was able to find Loganlathe.com, and they have all the replacement parts I need for the lathe. They have some urethane belts that would be a bit better, so I'll...

Also, I temporarily have a link belt on there, but the power transfer is not very good. If the lathe bogs down at all, the belt slips. But at least I can see it run. This is my first lathe, and I...

I have acquired a Logan Lathe model 922. I am fixing it up and have nearly completed it. The last issue is it came with an old 1 inch wide flat leather belt to power the headstock. I was hoping to...

Looking real nice! That should be one silky smooth setup when you're done. Do you buy chance have a personal comparison between rolled ballscrews and the ground one's you're using. Ground as so...

Awesome information! The PID loop makes much more sense now. I will definetly be checking into the IC listed. I'm picking apart the animation now. Thanks a lot for your time!

I'm trying to wrap my head around how a servo motor works. I've used both servos and steppers with varying controllers. I see how a step motor works, but I don't understand how a servo motor can...
