Sandblast texture

Looks Good! The texture comes right up to the edge of the letters.
Is that made from the texture tool or a bitmap 3D?
How big are the letters and bit used?

Thank You John. The background was a wood grain picture I converted into a 3D component, tweaking the z-Height to make it look good. The Letters were a font(type), converted into "vectors", then converted into a 3d Component. Made an outline to the letters 0.0625" bigger then the letters, so it didn't cut the letters faces. I took the backround and cleared the area where the type went (so I had my background with "holes" in it). The letters are 1 5/8" tall, only used a 0.125" ball nose to cut. 7.25"x30" sign took 1.5 hours on a standard Bot. (not Alpha). Hope I explained it OK. Takes alot of tweaking, which I still need to do more of. But I am hoping I am on the correct track.

If this is still an open issue............

I had the same problems last summer when I got my shop Bot and started in the Sign venture.
The POAs that we make certain signs for are in the western N.C. mountains and wanted a "rustic, balsted" background in theior signs.
We worked with it and worked with it ! In fact we bought Aspire for that simple reason.
But still had issues!
We had Shop Bot send a tech in to help us out (Ryan)
Ryan caught on to what we were trying to accopmplish and had the idea to change the moves to jogs or vice versa.
The Bot was lifting to clear vectors and leaving a herky jerky texture just like the photo that was posted.
His remedy worked great!
After we/he figured this out he assigned a post processor that had no moves(only jogs) and when we do a textured sign we just use that post processor .
Hope this helps.

I don't understand, but I think you had to slow down the jogs?

I would just change the jog speed or the move speed manually when running the file...no?

Mike,

What was that Post Processor called (do we have it on our machines)? Or can we get a copy of it to try?

Ryan Rocks!

I have a vector sandblast texture that works well

Nice looking texture! Do you cut this as a V-carve path? (I sent you an email...)

curious about this:
has anyone in this forum burned up spindles running 3d files using HDU. we have had to replace two 5hp perskes and one columbo immediately after long runs.
Then we paid thousands for an exchange spindle.
Could be we were doing something wrong. Was using small carbide bits. could not use dust collector. spindle running 24hours straight.

Dick, I don't run a spindle but use a router. Are you running fan cooled spindle? Would a water cooled do better for longer runs? If you are cutting HDu can you go to a smaller spindle (2.2 hp). HDU cuts so easy. I am also curious about this post processor edit that Ryan did for Mike. I have one customer that I cut signs for and he still prefers to blast as cnc texture is still not close enough for him.
Mike can you post a pic of your texture results? Very curious to see them.
