1911 Grip with USMC Globe & Anchor

Post by wb9tpg »

I'm really loving the laser module. I had to alter the GRBL post processor to remove any Z motion. At first I was tempted to remove the Z entries but I decided to use the scale factors to accomplish the same thing by reducing the motion to 0.

Here are the entries in the customized PP and I thought this was a clever approach to share. I also included the $32=1 at the beginning so I never forget to turn it on/off. I can almost do it with one post processor if it had one more tweak to it.
+-----------------------------
+ Reduce Z motion to 0
+-----------------------------
VAR Z_POSITION = [Z|C|Z|1.3|0.00001]
VAR Z_HOME_POSITION = [ZH|A|Z|1.3|0.00001]
And the new Laser Module does really nice work. J-Tech 4.2W spindle mount laser (80% Power / 1100mm / min).

Nice job! I see your fixture seems to be working really well too.

And I'm in a US Navy mood today. First time playing with scaling a STL on one axis only during the import. Also, I tried Hatch Fill with the Laser Module for the first time. It all worked. I think I finally for my post processors sorted out.

As I mentioned before, beautiful piece of work.
But I gotta ask.
You mentioned before that you set the Z to zero movement.
If that's the case, are you not loosing focus when burning the on the curvature of the handle?
I have the J-Tech 7 watt, and the focus is at 1.5", which is .125" above the work.
Being that it has a shroud on it, that doesn't leave much room for Z travel. (3D work)
I've been doing all flat work with other laser software.

The depth of field for the laser is large enough that you can easily get away setting it to 1/8" above the workpiece and running the job that way. Keep you from breaking your laser unless you're careless

Gee wiz Vectric.
I did not know that I used an unacceptable word in my previous post.
And for that I do truly apologize.
However, I thought this forum was for the members to freely help and learn from each-other by exchanging thoughts and ideas.
I think that you have a great product, so it really surprises me that you would feel so threatened by my word that you find it necessary to censor and re-word my post.
Kind of reminds me that one of my hobbies is that I keep a few chickens.
What you did to my post is on the order of the aforementioned droppings.

LOL, it seems like these days everyone wants to get in the act. Once we all cancel each other out we will be standing around kinda thinking, well, maybe that guy is not as bad as I thought, nor am I as perfect as I wanted others to believe.

Guys I posted these projects to show the capabilities of the Laser Module and possibility get some constructive criticism. Thank you

It's not at all my intention to hijack your thread.
It just pissed me off what they did to my response.
You don't need constructive criticism.
Those handles look fantastic.
And I didn't know that you could laser on a radius like that.
Soo, I still learned something from your post.
Thank you.
