It is a shame there isn’t a correspondence between raster engrave greyscale values and cut and score power levels. Otherwise it would be easy to all the tests with one big raster.
Also it would be great if some special colour were reserved to give default power settings. For example grey vectors could set the power and all other colours behave as thy do now, just identifiers.
Would be great, but thinking the part where he said the template took 6-1/2 hours to run means we aren’t going to get a pre-burned sample. Even the last single row took more than an hour. Don’t want the shipments to get any slower.
Oh, agreed. I wasn’t even thinking it would be a pre-burn sample from each individual GF that is shipped, more of a generic one they could have a bank of them churning out in the factory, to be included with ProofGrade shipments, or separately ordered as a separate product. I’d personally shell out a few bucks for an (accurate) guide piece along with a stack of ProofGrade.
But yea, no, not something that would delay shipments any longer!!
@jamesdhatch, does it make much difference how large each rectangle is? Can I resize this to 1/8 x 1/8 sized squares and get a good idea of the color and depth? Or do you need a large enough area to REALLY get a good idea of what the settings will do?
I’d like to use as little space as possible and speed it up if I can.
That one sort of surprised me - yeah, it’s a 5IPM, but it’s also only a few blocks that are less than 1 sq inch. I knew it would be long (because of the speed) but an hour & half really seemed over the top.
I made this fairly small (3/4") which gives a nice little piece of engraving. Much smaller and I think it might get too small - especially if you decided to play with LPI as well. This was my compromise.
I’m also not sure how much time you’d save because you’d have even more time being spent by the head starting & stopping. It’s not like a normal engrave where you’re doing a single large area. Each box is a series of starts/engrave/stop/repeat and the ends of the lines where it stops, moves the Y and then restarts is a fair amount of the time it takes to engrave as you get smaller & smaller.
Yes. I’ve not seen a laser that was able to span multiple objects with varying power in an engrave. That would be a very cool feature thought and the GF power supply ought to support it.
The diamond knurl tile that @mpipes shared in free laser designs exhibits a high level of dynamic power control.
It amazes me to see the power ramp up as the laser digs to the bottom and ramp down as it climbs to the peak. The engrave results in strings of 4 sided pyramids.
Why is it when I upload this .svg it appears as one solid image? Each box can not be individually selected. How do you set the speed/power for each box if you can not select them individually?
Ahhh…figured it out. When I opened the file in Inkscape, all the boxes were black. I didn’t realize I had to change the color of each box to something different.
