No, no blocker. Not sure what’s going on. Can’t do it from my phone or laptop either
Also- 404 when I click your link. Login issue maybe (I do t have an account, so no login)

Interesting.
Yeah, it seems you need to be logged in, that is new to me.

Pulled this 12v 8 watt led off one of my quads, and hooked it up to a 12v pin… Might be overkill, lol

If you can get your hands on a couple 12v rgb leds the firmware will change colors from boot to job done…and not so bat signal bright.

There are some cool videos out there of people making their stepper motors “sing” tunes. I swear my 3DP was singing something over and over while it was printing the core.
I have 32 feet of addressable RGB led tape… what pins do I need to use?
Thanks Ryan
Frivolous and chicanary, but I love it.

I once printed a Star Wars figure that made the steppers sing the song while it printed. I should dig out the STL but it was a long time ago. One of my worst prints though, IIRC

Open the firmware and scroll the very bottom of config.h you can set it all up there. Make sure not to use more than your board can handle. I did 12 just fine without any issues. More than that, I think you will need another bigger power supply.

Some time working on a couple things last night-
MicroSD to SD extension on the box for file uploads
Z-probe wiring and ESP3D macro working. I wasn’t really having any troubles with but changes before- just running gcode files as separate jobs- but this takes away a little of the fiddling with the z-axis after the second or third bit is exchanged.
Basically- job 1 ends with a G28 z command which homes Z to the top, then a G0 X0Y0 which moves XY to the start origin. Switch out bit, place the z-probe plate, hit the macro. It’ll drop down until it makes contact, sends a G92 Z0.5, raises Z 5mm so I can remove the plate.
As long as my consecutive jobs don’t start with a G92 zeroing command, it’ll pick up from there and continue.

Do that in a text editor, then put the new file on card as FIRMWARE.bin and flash it?
Thanks Ryan!

Fun with lasers
Hooked up independent 12v in, and PC9 plus ground PWM. Temporary harness
From the tablet- in Terminal
Ran M3 I
Orange led popped on. Good sign
Took a few minutes to get it running but that’s only because I forgot about the safeties. Marlin only sends the laser PWM on G1 moves
So- set up a little 2.8mm thick piece of balsa and types in
G1 X25 F240 S250 and hit go
Single pass at 4mm/sec, 99 % ish power .
I was getting some reverberations in the module, due to the slow speed and the cantilever. Very regular periodicity.
That went away when I pushed speed up to 5mm/s. That’s fine, since I’ll be doing cutting of 1/4” at 6mm/s with 2 passes for a nicer cut
So happy right now, lol. Such an easy addition.

Ok, now that it’s looking like I’m only a few days out from getting to really play with the laser- I’m thinking about enclosures and ventilation
The new design of the LR3 whereby it is entirely on the top of the table, is a real Benefit here. Since I don’t plan to be using an enclosure with the Router- my overhead dust collection prohibits it , and sound control isn’t really an issue - it needs to be either light enough to lift into position by myself, or ‘knock-down’ capable so that it can be easily assembled in place/ disassembled
I’m thinking about making 4 side panels using 2x2 material, rabbeted to accept 1/8” inch hardboard panels. I can recess
Magnets onto the corners, that will allow me to just click things into place . A top panel will contain a hinged lid, and an orange Perspex window, and a 4” port for extraction- porting out the nearby window. Back panel will need cutouts to allow the rail and the belt to pass through, and a gap in the bottom of the left wall for power cables and air line for air assist.
Now- heading downstairs to start on some
Measurements so I can do some calculations to see how heavy this thing might end up being.

Got a little laser cutter bed put together, figured out the offsets for the laser spot compared to home XY and made a macro to move it into a convenient start point, then burned a little L denoting the front left corner of my bed for positioning.
Also wrote a little test macro for a ‘first burn’ a 25mm square, traveling at 240mm/min, 100% laser power.
3.2mm ‘laser’ ply, cut in 2 passes (+AA)

You need to a get an air blast. If you have a compressor, you can get one for $10 on Amazon. My 2.8W is so much more useful with it, and the cuts are as clean as yours.

I have a 30l/min air assist running every time I’m cutting.
Not sure I can handle the noise of the router, dust collection and my crappy 1gallon compressor running every 30 seconds during a cut
Curious what made you say that though- I thought my parameters were pretty good.
Also- air blast isn’t coming up on Amazon, other than toys or purifiers. Got another term I can search?

Oh, yeah, I know. But it makes for a real noisy basement shop with wife WFH in the room right above.
I really should just ditch the crappy Ryobi pancake and get a California air tools vertical. But not in the budget right now
