Z Axis Control for Avoidance

[Wheelz (Peter Wheeldon)]

Has there been any advance in the control of the Z Axis for the purposes of obstacle avoidance?
I have a fixture which holds 12 nested parts. Each part has an up-stand which extends above the laser nozzle. Be nice to be able to program a Z lift between parts.

How far above the material does the obstacle extend?

[Wheelz (Peter Wheeldon)]

About 20mm. I have 12mm clearance from the nozzle to the engraving surface. My “workaround” right now is to program dummy, 2% power engraves away from the up-stands to manoeuvre around them.

Wait… nevermind. EDIT you have a Diode… I had linked to a previous post of mine suggesting, but obviously (now that I realize you have a diode) this will not apply to you.

Using a 4” Lens in the 1” Position is Amazing

I finally did this experiment today. This is something I have contemplated for a while. The reasons driving me to want to try this were: increase the safe Z distance from the cone to the material reduce the potential for contamination entering the beam opening at the top engrave acrylic without air assist (because it engraves so much better without it). Doing this without air assist will cake the acrylic on the nose cone and often lends itself to lens damage. I bored out the tip of…

Not sure how you concluded I was using a diode. I’m using a 100w co2.

@Wheelz

Not sure how you concluded I was using a diode

So the linked suggestion could be useful for you if you’re using a 100w CO2.

I saw this as well @Stroonzo.

@Wheelz, please keep this profile up to date, so we do not have to ask each time you post, or provide responses that are not appropriate based on what we can see. It wastes everyone’s time.

Ah yes. About a year old. Needs updating, lol.
