This was my dad's account, he passed away last March and we are thinking about selling his Shopbot CNC Router but having trouble finding someone who can operate one. Looking for advice on how to go...

I wasn't trying to stir up controversy with my water test post. Your response is one reason I don't post much.

I put two pieces of trupan in water along with a piece of plum Creek mdf. I left them for 4 days. The trupan gained about a sixteenth of an inch. The plum Creek swelled about one quarter inch....

This may be old news but Aspire 4.5 is available now. It has many new features including my favorite of being able to specify how far nudge moves nodes.

I believe you are the one who suggested the 1/8 inch mdf in a previous post.

I tried it and consider it one of the best suggestions I have read on this forum. The 1/8 Inch is cheap and I...

I have lasered a few bats and the laser is more forgiving than the bot. The problem with round objects like bats if your engraving is very large the laser will lose focus. They make indexers for them...

Don't mean to HiJack this thread but I am having similar problem with 3.8.6. Mine isn't as serious but it is still occurring about once a week.

It will slow down to a very low feed speed...

I had almost the same thing happen last week. I was cutting a simple profile in mdf when the bot slowed down to a crawl. I tried speeding it up with the shift> keys but it kept moving at the same...

I have been having some random problems with the spindle shutting down. Last night it would shut down every time I tried to run the spindle warmup routine.

I finally gave up and this morning I...

I tried the 1/8 inch mdf over my trupan spoilboard and find it works very well. I cut mine into 2' x 4' pieces. That allows me to replace only the sections that need replacing and I can sand both...

I took the plunge and upgraded to 3.8.6 on a new Windows 7 HP computer.

I don't want to brag too soon but I worked the bot pretty hard this weekend without a single problem.

I removed every...

I had not seen the bot move that fast before. It was a bit scary when it took off at 12 ips. I will try your suggestion

Thanks

I knew I would have to upgrade the firmware with the new 3.8 software but I didn't know it had to be updated when I changed computers.

I will try to remember that if I have to revert to the old...

I had some problems with the old Dell about a year ago so I don't know know how dependable it is.

I think I may put 3.8 on both that way if I have problems I can switch computers.

I have a PRS Alpha with an Automatic Tool changer and spindle, Purchased in 2010.

I am getting com errors every once in a while using an older Dell with XP.

I am getting ready to take the...

Thanks for the info about the grounding clip. It should save some time but more importantly it is one less thing I can forget to do.

I tried Ron's suggestion of not using the clip on my spindle. When I touched the grounding plate to the bit the light came on just like it would with the clip attached. I ran the Z zero routine...

Gary

The green was my guess but I wanted to make sure.

Thank You Very Much

After 2 1/2 years I finally forgot to remove the grounding clip before starting the spindle. It ripped the wire completely out of the plug. I can't find anyplace in the manual that shows where the...

Thanks Gary.

I have an ATC will this reset affect any of the settings for the tool changer?

Had a comm error yesterday and when I restarted my move speed had been changed to .2. Running the c3 routine took forever so I changed it to .5 then to 1.

That seemed about normal. Does anyone...

This subject seems to be a common problem.

I work in aspire on a Windows 7 computer. I save it to my network drive and load and run it from my xp computer which runs the shopbot.

The last comm...

I too am running off a netwmork drive and I also notice a pause every so often when doing 3D carving.

This is what got me to wondering if the network caused my comm error.

If I decide that is...

Thanks for the response.

I read it over several times and still can't tell whether this happens in memory or is reading from the hard drive during the processing.

Could be my age is...
