Mike,

My motors are labeled A6488-9412KTG which is the same motor that came with my indexer. The other info on the motor is 2 phase, .25 step, DC1A, 4.39ohm. My G4 board has g202 drivers.

Before Christmas I upgraded my PRT with 4G board and PK299 motors. I used 7.2:1 motors and an 80VDC power supply from shopbot. My business is changing from cabinets to 3D work and I was looking...

Thomas, Thanks for the link, I remember reading Brady's column when he wrote it but had since forgotten it. I will definately start with playing with the software.

John, I have a standard...

Recently I have been doing more carvings and less panel cutting. I am looking at upgrading my bot to deal with the chatter caused by short, jerky movements. The three options I am looking at are...

My 2001 PRT standard is 66.25" center to center. I believe the only difference between standard and alpha machines is the control box and motors.

I forgot the basics. I did not make sure that the aspire toolpath was only one pass. Fixing this made everything run as expected.

The new "turn a part from a Parts Wizard File" option appears to cut in a back and forth motion and does not reset the turnings counter. I get a runtime error 6 if I have more than 536870 degrees of...

Great Work. I have done similar work based on chip carving patterns and noticed the trance inducing effect of the woven forms. It's nice to know the carvings have a name, Mandalaa is a much more...

Do you know where this part goes? I see three attachment points and I am wondering if the hardware/frame will give it the vertical bend? I find that if I try to put myself in the shoes of the...

Hi all,

Does anyone use an AC power conditioner for the shopbot contol unit and control computer or can recommend one? I am looking at eliminating noise from other machinery in the shop.

If you are levelng with a builders level try turning the level 180 degrees and seeing if the bubble is still centered. As a surveyor I always take meaurements in both directions to cancel small...

On everything we do with the shopbot we assume that the bit is travelling on a flat plane. It appears that you are zeroing on a block at one end then sliding it to the other end on the table to...

I had a problem last year with the indexer virtual tool where I was turning a round blank that mysteriously tapered. I could watch the steps actually change on the screen when they should not have...

The higher your ceiling the better it will work. I tried hanging my cables with a 7' ceiling and had trouble with cables catching on the Z when I was cutting on the whole table. The object is to not...

Check with your local building inspector. Most states require a minimum of 6 inches between the opening and combustible materials.

George,
There was someone doing custom signs at Busch Gardens in Williamsburg VA this past summer. I didn't have time to stop in but it appeared that he had precut signs that customers would...

You have mail.

Shopbot makes a relay control board for the air drill and spindle fan that has five relays on it. From my talks with shopbot support I believe this board can be used to turn on and off a dust...

Thanks guys. I did not realize that C99 had what I needed (never explored all the custom files) so I will be progamming this morning.

Is it possable to add a new programming command that would act like MH but would move to coordinates that are defined in the user variable file as opposed to (0,0)? I would like to move to a parking...

To everyone that tried to help:

Shopbot was nice enough to exchange my relay board but the problem continued. I started to play with my connections and found that the 24v power supply, the 4G...

Mike,
The relay is 24v solid state. After reading your post I checked the voltage at the coil at SO 5,1 and SO 5,0. At SO 5,0 I have 21v on one post and 0v on the other. At SO 5,1 I have 21v on...

I am finally completing installation of my air drill and think the relay switch may be bad. When I do command SO 5,1 then 2 leds light on the drill control board but nothing happpens. If I jump the...

I had a similar problem going from turbocad 14 to vcarve pro. First I saved the file as a turbocad 12 .tcw file and then converted the new file to .dxf

Have you checked that your router is attached tightly? It may be a loose clamp since the error is allong the X axis.
