Barry, that's a fantastic machine! Sorry for taking so long to respond, but I sorta dropped the project for awhile. I still need a sander, and I still think a wide belt sander is a better option...

Thanks so much Gerry. I think I have a decent idea now. I was expecting the oscillation to be a separate thing from the belt tracking, but what you describe can have the same sensors for the belt...

Thanks so much! Any way to get some pics? I'd love to see the air cylinder and cam/actuator. Also, if you can get any pics of how the belt tension adjusts- I assume its air cylinder on the top...

I'm on a quest to build a wide belt sander for my woodshop. I make wood parts with a CNC router, and the sanding afterwards is a huge bottleneck. I want to make a wide belt sander that has an...

I'm a CNC guy, but I had a retail shop where we sold imported lamps that were hollow heart shapes with one end open for the light socket. I think they were fiberglass, but I'm wanting to reproduce...

Hi Al. Thanks for your help. Is the shell of the connector considered ground? Or do I need to use the pin on the connector that is the common?

Thanks, I'll sure try that. I don't have a scope, so I'll assume that the short time length spikes are enough to trigger a reset in Mach 3.

What can cause this sort of voltage difference? I...

I'm chasing a problem with my system where it intermittently resets Mach 3 during operation. In checking wiring and ground voltages, I found a .25 voltage difference between ground on my Controller...

I want to upgrade my CNC router that now uses Bishop/Wisecarver rails and wheels to use linear guides.

I have two questions about how to do this. This is on my X axis, and the rails will be...

Al, thanks so much for your help with my speed control wiring problem. I now have speed control on my spindle!

Now I'm trying to wire a relay to turn the power on and off via Mach 3. I have it...

Thank you AL! I now UNDERSTAND how to wire a POT, and I can wire up speed control.

I have my CNC and computer etc grounded pretty well, all to one central ground, except for my VFD. If there...

So THATS what that voltage was for! Excellent. I was planning to tap into the same power supply that I use for the CNC4PC speed control gizzie.

I fried a parallel port buffer board when I was...

Al, thanks for the quick reply. I have both a 5K and a 10K pot, and I'm just having a heck of a time understanding this.

When I measure the resistance with my Simpson I get a varying resistance...

I have a VFD that needs the typical 0-10V DC to control speed. I want to use a potentiometer to adjust the speed.

I'll be supplying 12V DC from a small power supply. I just need to vary this...

I'm getting closer to resolution. I removed the CNC4PC speed control apparatus, and turned off the spindle settings in the Ports/Pins config panel. When I do this, I can get the X axis to operate...

Mike, you are right. Actually, I have a disk with the unchanged original XML file, and I'll be able to copy that to the computer and see what that yields. I'll also spend a few minutes rechecking...

Mike
Got it. Common is 5V. I need to step back for a few hours or I'll loose it and pull the rest of my hair out. I'm getting inconsistent results, or there are some other variables that are at...

Mike

Thanks for the follow up. I replaced the computer, installed Mach 3 on a new machine and verfied the ports/pins etc. On the new machine I have exactly the same problem, so its not likely...

Mike,
I measuree the voltages at the Geckos step pin. On the X axis 202's I read -5V from common to step. I don't get a change when I change directions using the jog key. Also, when I measure...

My control box has LED step/Direction indicators. Do these work to detect the presence of signal?

Also, what sort of logic probe would you recommend? I can see that I may need to take at least...

I'm Pacific Coast time, so I'm just getting rolling now (sleepyhead). I'll start working on this shortly.

I use a breakout board that is an Ascension 1000. I believe this was made by Bob...

I just spent a day fussing with my CNC, and I can't figure it out. I need some help so I can make a more logical troubleshooting effort tomorrow.

My problem STARTED with an intermittent coil on...

I'm having some problems with a Gecko driver, and in the process of horsing around inside my controller I may have caused more problems.

Right now, I need to know how to troubleshoot Mach 3...

I have been having an intermittent problem with one coil not working on my Xdrive motor. I thought I found it a couple of times now with loose wires or plugs, but each time I think I have it fixed...

At that sort of operating temps, I'm guessin you have a materials expansion problem. There is a difference in the expansion rates between metal and plastic. At room temps they are one size, and at...

I'm a shopbot owner, and I just completed an upgrade on my PR. I installed a new gantry, new Z axis and motor, and a new Ascension 1000 controller. Overall, its a big improvement, but it could be...

I work on a Biesse Rover with Biesseworks. We use CabVision, Artcam and Biesseworks, each has its place. We just did a large cruise ship interior using mostly Autocad DXF files imported into...

Ger

I found the BWC rails to be plenty smooth enough, and a big improvement over the Shopbot PR's old wheels on the edge of the unistrut method. Particulary on the Y axis, where I have...

I bought a used Shopbot PR 120 model about four years ago, and just the last year decided to upgrade it. Here are a couple pics and some info that may help others with older shopbots thinking about...

I'm gonna strip it. The screw and bearings are great, very precise and in good shape. It also has the motor mount that lines up perfectly, and the lovejoy coupler, etc.

I checked prices on new...
