Huge problem for me. I haven't even looked at the machine in almost a week cuz I'm just disheartened.
I can understand being disheartened, yet I so look forward to the day when I acquire a new PowerPro myself. I know many users who have absolutely loved theirs. Shopsmith will help you get this fixed I am sure. That's what they do. The folks there today have bent over backwards at times to help an owner who was having problems with machines made long before the owners of today's Shopsmith had the company. The PowerPro is their baby.

I encourage you to get back in the saddle and tame this one... They will help you.

Skizzity, I can relate to your frustration however please realize there are fixes for your headstock overheating. Please read the thread "Power Pro Upgrade" by dmelonson1960. You will find it in the Woodworking Tool Review part of the forum.

Also a call to Shopsmith and requesting to talk with Wes Powell and fully explaining your problem will surely get results.

Just wanted to give you guys an update. I spoke with Wes Johnson @ Shopsmtih in late June and was quickly sent a replacement power supply. That is a good news-bad news story.

The good news is that I no longer have the sagging problem as the system gets hotter under use.

The bad news is that it did not fix the overall problem of stopping with the RPS Error 0 after more than a half hour of constant use.

July was a busy month, so I haven't had much time to work on the Shopsmith, nor on the staircase spindle replacement project that was causing me to need to use the tool for long periods of time.

My next suspect component is the sensor board, as was discussed in this thread earlier. Wes was contacted 15 July, and responded saying he'd get a replacement one out the next day. By 28 July, nothing had arrived so I emailed him again and he said he'd check on it. I haven't received or heard anything since.

I am getting to the point of considering sending the whole thing back, but don't want to do that if I can avoid it. The Shopsmith is primarily a table saw, and if it can't operate as one more than a half hour every hour and a half,that's just not acceptable. That's especially true after upgrading to their premier motor system.

I still hope it's just the bad luck of a failed individual component, not an inherent design flaw.

It will operate all day long as a table saw. The heat buildup comes from high speed running as a router/shaper. There are a lot of technical reasons for the issue, but yours seems to be an acute problem. I know I have had the error once or twice after an hour or more in a pretty hot environment. It the PowerPro had this kind of issue, it would not be as popular as it is.

If it were me, I would send it back. At this point I think they need to take a look.

JMHO from another owner .... :)

Are you cutting board after board the whole half hour? What's the running environment temp?

My Shopsmith is in an air conditioned basement maintained at 68 degrees year round. And no, I'm not constantly cutting. The duty cycle is 20-25% cutting vs idle. I'd turn it off between cuts, but that "Confirm" feature of the user interface for the 3450 RPM speed I'm using makes it clumsy to do lots of start and stop.

You almost certainly have a bad component or connection. It could be a cold solder joint, or a cracked trace on a circuit board -- those are often temperature sensitive and cause intermittent failures. And are a royal PITA to track down. Heat guns and freeze spray can help, but that's the mother ship's problem.

There are many, many satisified PowerPro owners that have never had this issue, so it's highly unlikely to be a design problem. Keep after Shopsmith until it is fixed.

Excellent point BD, I have a Bosh job sight radio/CD player, digital clock, LED and battery charger, 3rd one for free after the initial one. In the garage shop.
For about 5 years when it drops below 46* clock freezes time on it and nothing works on it, BOOM, when it warms up above 46* clock is accurate all all works!! Something in the circuit board, ya think. ;)
