I thought so, but wondered if you had a "trick"  ;D

Nice prints!

I did use supports for the 3 sided one. I do not have one of those zero G printers  ;D

Very neat!

Did the 3 corner one print without supports? (I'm not seeing how that's possible)

I can see a few problems there, but lets deal with the laser not turning off.

Can you control it from the laser panel, when you click on / off or pulse does it turn on and off immediately?

What do you have laser min set at? Obviously it should be 0 to turn the laser completely off.

Hi, i've got the laser set up and working great, however having an issue with the laser burning the path into whatever it is cutting, i've attached an example - in this instance it wasnt an issue as i was making a stencil however for engraving i'd obviously like a clean finish. any ideas please? thank you. Ben.

Sounds reasonable!

 Thanks.

Because if you can get 2500mW from a 1600mW laser diode by supplying a slightly larger power supply and increasing the current, what do you think a chinese company is going to do.

They probably use this 1.6W diode in the 2.5W lasers, I don't know about the 5500mW version but you can guarantee it is overdriven from its datasheet specification.

I use power 200 as my max power whenever possible for this reason, if the same job can be done at 200 instead of 255 and needs a lower feed rate, so be it.


Here is someone using this 1.6W diode at 2.8W

The lasers that come with Eleksmaker machines are severely overdriven.  If you run them at their advertised 2.5W power (and the ones with higher ratings are even more ridiculous), they'll start to take damage and not cut as effectively, burning out much quicker.

Have you tested all the different power lasers from Eleksmaker to make this statement?  How do you arrive at this conclusion??

Custom Size Frames / Re: Little CNC mill
« Last post by Stonemull on July 24, 2017, 11:09:40 PM »
Managed to mill my first pcb using FlatCam, double sided, drilled and took 4 attempts. I started with a 0.5mm track width design is pretty much my regular.
The first one I used my surface probe to set the zero but forgot to readd the 1.56mm pcb thickness offset that is removed by the software, I heard the tip of the engraving bit snap off in a split second.
The next one I had set too deep in software, also snapped a tiny part off a new hit.
Next one I realised that 0.5mm tracks were never going to work and that I shoukd use 0.21mm as the bit width setting.
Redesigned the board quickly with 1mm tracks and larger pads and board 4 was acceptable.
Drilled 0.7mm holes and 5mm deep alignment holes for a pin, then used board cutout with 5mm buffer, which I realised in hindsight is better done after the reverse is milled..

Side 2 I thought would be horrible but I dropped the mill depth to 0.05mm from 0.1. and the tracks came out really clean.
Clean up with steel wool, bench grind the final shape, assemble and it works !

Thanks Ralph. Just confirms how much of a newbie I am at all this. I thought I had the measurement units set.
