Hi, Frank. No, I'm sorry. I sold it for $8,000.

I haven't played with my ShopBot in years, so it's time to give it up.

Asking $11,000.


ShopBot PRS Standard, 96x48 table
HSD 2.2HP 220V 1PH Spindle
Driver laptop
½" bits and ½” and ¼"...

In order to get the flexibility I want, I'd have to go the route of the master file with a little programming to prompt for the rows, columns and offsets. It wouldn't be difficult and it really...

Dana, I'll check out that section in the manual but I'm really interested in a way that lets me cut a bunch of copies automatically. I don't want to have to tell it where to start the next copy.
...

I apologize if this has been covered elsewhere. I'm sure it has, but I must be using the wrong search keywords:

I routinely create a small design of which I would like to cut multiple copies from...

How do you cut the tabs afterwards, Steve?

I just also found the 1/8" version of that flush cutting bit: http://www.amanatool.com/bits-fv/46197.html

This 1/4" bit might work OK if you can't flip your cut sheet. In my case, the cut is 1/4"...

Paul, that is the perfect bit for this job as long as the sheet you're cutting is still sturdy enough to flip without breaking apart. (I don't have enough room in my shop to do the sandwich method.)...

Adrian - It's supposedly loosely based on BASIC, so clunky is a given. And, no, you don't get to be my hero for giving snarky answers. ;)

Bill - You, on the other hand, are absolutely my hero!...

Hi, y'all!

I have been using Excel to generate some fairly simple 3D cutting instructions. But I'm quickly getting to the point where I need to start programming nested loops and that's just not...

Brady - could you explain why you say you can't overtighten the motors on the PRS? I imagine you could cause undue stresses and wear on the motors if the gears are engaged too tightly.

My...

I made the following changes:


Climb cut first followed by conventional cut
used onion skin instead of tabs
got rid of leads and used spiral plunge instead
used a specialized CNC bit...

That's a great price for that bit! I don't see the CNC version on their site though (C1072.)

I found a Whiteside bit that'll work. The part #'s for their CNC bits appear to start with "C" and are otherwise the same as the handheld router bits. So, the bit I ordered, C1072, is the CNC...

Thank you all for your input! I'll post when I get a chance to implement all of these tips and get some results.

Andy

It's a Bosch bit, wouldn't you know it.

What do you use instead?

The spindle assembly is rock solid. There is no wiggle in the z or y direction. However, with a bit of oomph, the x axis does move a little (~1/16"). My guess is I need to make sure the gear on the...

David - I suppose the fact that I hadn't yet checked for looseness in the assembly makes it appropriate that you warned me to turn the spindle off before grabbing the collet. ;) I'm not going to have...

Randy, Bob -

Wow... It's amazing what you miss when you read things too quickly and before the coffee's had a chance to kick in. Like, the whole point of the post. :eek:

Thanks for the great...

Thanks, Randy! I'm reading into your post that the flaws should be expected and are normal with the approach I used.

I was cutting "conventional" (counterclockwise on outside cuts.)

I'll give...

I am using a 1/2" diameter, 2.5" cutting length straight bit to cut a guitar body with lots of 2D curves on 2" deep profiles (in four passes.) For now, I'm using MDF for prototyping. I need to...

I received my EE Controls D-MDC 30 Powerline Filter ($105 including shipping from Control Source in NC) yesterday and installed it (in a separate box outside the VFD.) So far so good! I currently...

Alright... you beat me into submission. I got a cheap PC off craigslist with an almost clean install of XP. I got rid of some Dell garbage and everything nonessential I could think of.

Together...

Hmm. Yes. There's that warning again. :rolleyes:

I have to admit that I'm reluctant to try this on my own laptop with my own ShopBot with my own $200 sheet of material, but I do welcome others to...

With all the warnings about having a dedicated controller computer with nothing running but the barebones essentials so as to not distract the computer from the task of driving the ShopBot, I am...
