I finally tested my wireless controller and it works great...at least in my situation. I didn't notice any lag over what is usual for Mach 2. I only went maybe 15 feet from the pc, so I can't...

Ynneb, Couldn't you label the controller with one of those white permanent markers or some stickers? I don't see labeling the controller as a big deal. Otherwise the controller is nearly perfect. ...

If you use Mach2's KeyGrabber you can adjust not only the total throw of the joysticks, but use exponential. Exponential keeps movement of the axes small when the joystick is near the center. It...

This has a 100' range and is a new product. I just bought it and it seems to work well on Mach2 at my office. I have yet to try it with the machine, but I will either today or tomorrow.

The...

I checked the power supply for the servos and the drives and they were both good.

I also checked for lost steps (ie - ran the program until it jumped all over the place then went to almost to...

I use ballscrews driven directly and I can push the axes and make the screws turn.

I am now thinking I may have a problem with either the drive power supply or the servo power supply. I talked to...

Ooops, sorry. Yes, it is the PC4 or PC5, not PC45. Depending on what pin output you want. If you call US Digital, they can hook you up with the right stuff. I have E5 encoders and I needed their...

The problem is that it works ok in the beginning of the part program (the first couple of minutes) and then starts having problems. If I rewind the program and start from the beginning again it...

Bob,

If they don't want to take them back just order the PC45 (http://www.usdigital.com/products/pc45/) It plugs directly into the E2 encoder and gives you differential output.

I have it set for CV (continuous velocity) motion in Mach 2 which should take care of that, I think. It has a setting that will keep the axes moving as long as the next segment is within so many...

Well, I have OneCNC XR Professional and that is where the part program come from. I made a 2" hemisphere and a did a few operations on it. Anyways, I was cutting air above the tabletop.

The...

If anyone can help me find out what is causing this I would be extremely grateful. I added a differential driver to my open ended encoders to reduce noise, etc. That worked well. While I was...

Bob, yes it is very true. Don't even waste your time wiring up single ended encoders. Do it right the first time and you'll save a lot of frustration.

Al, that's pricey, hard to find wire alright! I found it priced near $1000 for a 500' roll. I think I will go with a local supplier who has the same spec'd wire. I only need to run 15' for my Z...

Also, for anyone else getting something out of this thread, US Digital has a FAQ and some of it deals with noise issues on encoders.

Here's the link:...

Thanks for the info and the link, Alex. I guess I will have to bite the bullet and get the line driver converter and then rewire all my encoders with 6+ conductor wire. I wish I had known this...

I bought my 3 990Hs a few months ago and have them hooked up to my servos. I have US digital encoders (e5S-500-375-EG) and they are single ended TTL units, from what I am understand. I printed out...

Thanks guys. You have to love a place where you can ask and learn. I think I'll end up checking the temperature using the roast of beef method. Then I can decide whether I want it rare, medium or...

Well, it wasn't exactly 1/8" sheet. I had 2" square tubing 1/8" thick, so it wouldn't warp much. I also couldn't use a backup sheet since I can't get behind the metal. I'll try heating up the...

I was only off by about 1/32", but it was enough to do it over. I am using a wire feed welder (Lincoln 135 Plus) and flux cored solder. I'm not sure what type of steel I have, but I can't change it...

I'm fairly new to welding, so I don't have a lot of experience with it. Here's my situation: I've been drilling and tapping holes. Three times I've had the need to redrill the holes because they...

Esjaavik,

Thank you for your detailed post. There is a lot of good information there. My question after reading this is: does it matter that there is some error? Follow my logic. For example:...

Thank you for all the info guys. I think I understand it now. Basically the servo will never be at the position it is supposed to, but it should be close. There is some lag and that is ok, because...

Thanks Kmed. That makes sense. Anyone know what the capabilities of Mach2 are as far as block processing time? I know it depends on the PC you have, but anyone have a rough idea? Thanks!
...

I was browsing the HSS area and there was some discussion that a faster controller is needed for high(er) feed rates. This makes sense to me, but it also makes sense that if Mach2 can output the...

I am deciding on what I want to drive and control my servos and was looking at the Rutex site and came across this page:

Just wondering how this worked out for those that purchased TurboCadCam. Does it have full support for 3D CAM? Thanks!

These are all good replies. I thank all of you, especially buscht for putting a picture up for me. Apparently there are at least a few ways of doing this. Can I ask what is the typical spacing for...

buscht, I sort of have an idea of what you're saying, but a picture would help oh so much. Does the vacuum get pulled through the holes you drill in the MDF? I assume the 3/4" offset is inside of...

I'm in the planning stage of a CNC router. If you are using a vacuum clamping system, your workpiece is directly on top of the vacuum surface, correct? If you need to cut a piece completely free of...
