Hey guys I'm all for automation, but a real easy way to increase your cycle time is to put a 1/4 inch piece of mdf on top of the bleeder board. Once your parts are cut slide all parts and 1/4 mdf off...

It scares me how much I see him, especially in the morning LOL
I'm traveling a lot, doing installs for SB. I'm on the road right now and I don't check the email posted in profile when I'm away. ...

I don't have a schematic readily available. All of my files are archived on a removable drive that is in storage in another state. The control circuits used are virtually identical to the...

Jon
Sorry your having problems. Your problem drivers are going into reset. I know of only 3 causes; Faulty wiring or bad motor, overheating, or a faulty driver. I’m assuming the same drivers are...

You probably also need to check how this unit will work with a restricted airflow (over heating). I'm guessing they have the 2 motors stacked in series, one blowing into the other to get that high...

It looks like an excellent choice. Good cfm, high vacuum, and a warranty to boot. Probably fairly quiet. Best specs I've seen for a canister. If you run out of cfm you can add another unit. A little...

Geckos won't work on a PR box as there are no step and direction signals (Unipolar design). Geckos on a standard PRT box will be slow because of the low step rate put out by the old controller. You...

What size is that capacitor in picture on the flickr site? It's looks huge.

I found the specs, I think the 48" max vacuum is a problem. Better off to find a different blower.
Here's the link to your model.

Looks like Morris is being left out ( he did start this thread). He could machine the tubes and include them in his kit. That makes it better for Morris and harder for DIY

I've bought some hubs at Walmart. I usually buy one that is compact for a note book that is self powered. Basicly by using a true 2.0 device it forces your computer to configure it's resourses for...

Hey Paul
I've updated my profile.

I upgraded my PR control box to a PRT box about 4 years ago. I was extremely pleased with the improvement. Likewise I saw the same magnitude of improvment going to Gecko's. Now in your case going...

Sounds like a comunication bottleneck. Check your thouroughput speed with the diagnostics tool. Using an inexpensive USB 2.0 hub between your computer and tool will usually speed things up.

More than likely you were shipped the wrong screws. The counterbore has been changed and you should have recieved 3/4" button head screws. The previous counterbore used a 5/8" socket head screw. Call...

All Spindles are 3 phase. In order to run on single phase the size of the VFD needs to be increased to compensate for the missing 3rd leg. The oversized VFD will supply 3 phase to the spindle even...

Jon you have mail

Most PRTs use 4 wire motors so the half coil method is unavailable. However using a higher voltage power supply will help with higher speed torque. Also properly adjusting the low speed resanance...

The Geckos are pushed in from the side. The box would have to be laying on it's side for gravity to be a factor. The Wagos can loose connection and it may just be intermittent. Very hard to trace if...

More to add:
I personally don't believe there to be a problem as far as the way the Geckos are mounted on the G4 board. The new black connectors are very tight and actually are difficult to remove....

Another note on USB verses using a PCI card. Up to this point I've found the Quatech DSC100 to be the best card and most reliable. The Shopbot software is being optimised for a USB connection and...

Paul
I haven't tried that particular card. I have tried about 15 others. Ones I thought would work didn't. If I were you give it a try as long as you can return it. Let us know how it worked out....

Here's the spec on the driver chip

Check your chip, but I think it's the SLA7026m.
I got the number off an old blown card and a piece was missing.

John, I'm pretty sure these are the same screws that came with the machine
