ShopBot purchase

Still available:

Model: ShopBot PRS Alpha 48x48

Here are the reasons why I purchased this machine and some notes:

  • Super easy to run, the control software is the simplest I have seen. The proximity switches and z-axis touch-off plate make it really difficult to crash and simple to set-up and run.
  • I can do all of the maintenance on the machine myself, ShopBot has an excellent forum and phone support. I have moved this machine twice and was able to do all of the wiring and set-up myself. If I had to, I could take the machine apart completely and move it through a standard doorway. The only reason why I am not keeping the machine is that I would rather buy a new one in a few years instead of having this one sit and collect dust. I also don’t know how long I will be at this job and they are hitting me with a non-compete.
  • Machine has low hours on it. Had about 100hrs on it when I bought it, might have 150-200hrs on it now. It is almost 10yrs old, but the new machines are not any different hardware-wise. I have upgraded the boards to the most recent version and done the necessary firmware updates as well.
  • This machine has a real spindle, not a router. The speed is controlled by VFD and it is quiet and powerful.

Specs/Includes (Looking for $10k for the whole set-up, including some preliminary training, and I’ll throw in the phase converter):
-PRS Alpha 48x48: (MSRP: $16,300)
-HSD 2.2HP Spindle and VFD ($2,619)
-American Rotary Phase Converter ($1,281)
-KentCNC Magnetic Dust Shoe with two brushes ($230)
-HF 70Gal 5micron Dust Collector 2HP ($200)
-Wireless Dust Collector control switch with on/off remote control
-Rockler Clear 6in dust collector ducting 30ft.
-Dell Precision Workstation loaded with ShopBot Control Software. Rolling computer cart, with monitor stand and LCD screen.
-Spindle collets, wrenches and associated parts and wiring.
-Operators guide.
-Wired/tethered emergency stop pendant with 20ft+ of cable.

I also have a really solid laboratory-grade workbench (black chemically resistant, super flat) and a fully-tooled manual metal lathe with working auto-feed that I’m looking to get rid of.

Word, I’ll keep an eye out.

What are the details/specs on the machines? I can pass on the info to the makerspace, and I also have a friend that said he may be interested in the shop bot if that’s still available.

Might be possible to meet up and show you my shop. I also have some friends in town this weekend so it might make things tight. Text me when you are around: 651-894-4436.

Laurence,

Sorry, I was out of town. I do have one interested party that is in line ahead of Ithaca Generator and has offered me the original asking price for the machine ($10k). I will let you know if this doesn’t pan out. As you can imagine, with a machine that is this expensive there are many logistical issues that can arise during the process of a sale, so I’ll keep you in the loop.

I also have a 2x2ft medium/low-duty machine that is currently in Boston. Asking $2500 for it (but that might be negotiable, I do need to sell it), with all of the bells and whistles including dust collection. This was my machine for a few years prior to upgrading to the ShopBot. Here are the details and at the bottom some examples of projects that I have made with this machine:

Zenbot 2424 CNC Router
Travels: X-24”, Y-24”, Z-4”
Table size: 30 5/8” x 28 5/8”
Footprint: 35 5/8” x 36”
Motors: 4 wire bipolar 285 ounce/in Nema-23
This rugged machine is made from HDPE with a proprietary linear motion system developed by Zenbot. The system features ball bearings preloaded on eloctroplated-zinc thick-walled steel rails. The result is a very stiff system with ultra smooth motion and zero slop. The Z-axis features 16mm rails with recirculating ball linear bearings. The drive system features 3/8 inch wide kevlar-reinforced urethane timing belts on all 3 axes, resulting in ultra precise motion and blazing fast rapids (500 inches per minute). The entire machine is bolted together with allen-head machine bolts so every part is replaceable. The grid on the large stationary table makes workpiece alignment a breeze, and the matrix of steel 1/4-20 threaded inserts make it simple to fasten the workpiece to the table. This machine is ideal for making Pcb’s (printed circuit boards), plaques, trophies, model airplanes, 3-d puzzles, picture frames, vacuum molding plugs, lighted lexan signs, business card holders as well as larger woodworking projects. Three-axis simultaneous smooth contouring enables the machine to be used as a subtractive rapid prototyping machine.

Features
Constructed of extremely durable HDPE (High Density Polyethylene) with Baltic Birch 3/4" 13-ply plywood top.
4 wire bipolar 285 ounce/in Nema-23 motors
Kevlar-reinforced urethane MXL timing belts on all 3 axes
Linear motion system with ball bearings preloaded on 1.25 " square 1/8" thick walled steel tubing on X axis and 1.25" square steel tubing on Y axis for ultra smooth motion with zero slop.
X and Y axis have strip brushes to keep the rails clean and smooth.
Z-axis features 16mm rails with recirculating linear bearings
Matrix of threaded steel inserts in the table for convenient fastening of the workpiece.
Assembled entirely with steel bolts so all parts are replaceable.
Turnkey system, comes with:
Zenbot 2424 CNC Router (Details above) - Machine has been cleaned and fully rebuilt. Bearing blocks have been replaced with OEM parts.
Hitachi M12VC 2-1/4HP Router
Gecko g540 4 axis control box (less than 10hrs on this)
Mach 3 Control software and Dell Precision PC
Precise Bits - Ultra Precision BOUP-1618-842KIT - Deluxe Bosch 1618 Collet Kit (contains 1/8in. , 1/4in. & 1/2in. UP collets, collet nut, spanner wrench and 118 ml of ColletCare)
ShopVac Brand Wall-Mount Wet/Dry Vacuum 5 Gallon Capacity
The Dust Deputy® Cyclone Dust Collection system
Battery Backup
