As in, ‘we live in interesting times’? :) Things have been slowed, somewhat, by by regular laser cutter going on holiday for a month, but I sent...
It’s only a 2-axis design. How are you going to raise your printhead? As to speeds and feeds, that depends on what you use to drive it - the...
It’s quite a price for a 2W laser, but looks well made. A similar unit from Endurance is under $200 and he will set up the mount to fit whatever...
Awesome job!
Cohesion is a Smoothie 32-bit variant, same as Smoothie, Azteeg, MKS, etc. After looking at various K40 machines, some come with external...
Upgrades & improvements on the K40 - K40 Laser
J tech haven”t made some special plastic - they’ve just sourced good quality orange acrylic. Most of the world isn’t within easy driving...
A toilet extractor fan and a piece of pvc and some 4” ducting will do the job. Just lie it close to the edge of the laser and it will pull all the...
A simple GRBL shield using your existing stepper drivers will set you back about $5 Get an arduino Due to go with the GRBL shield and run G2Core...
How long is a piece of string? I've got an industrial vacuum with a cyclone unit on top of a 50L pail with DIY activated charcoal in it and it...
Theres a bunch of software that will do that - Octoprint, Chilipeppr, etc. and handle your Gcode at the same time. A Raspberry Pi and its...
Heck no! No time wasted at all. What I will do is to try and cut 6mm dark acrylic with my new Endurance 5.6W and see how it goes. Damned postal...
My initial reaction from looking at your carriage is that there isn't enough of it to not wobble. The mini v-wheel gantry just isn't wide enough...
I sometimes work on a commercial 8x4 150W CO2 laser. It struggles to cut 12-15mm clear acrylic at a speed that doesn't result in the plastic...
Yep, you've only got one spare! But... orange is orange. These 'laser safety' companies are charging huge money for what is just normal coloured...
Thanks @Mark Carew
[ATTACH] [ATTACH] Today did the first test build, just to decide on which extrusion to use, what final size to make it, checking up on the balance...
What I didn’t have any of, and what I’ve been substituting ‘regular’ extrusion for is v-slot 2020. I ordered 5 600mm lengths and it arrived...
For a 445nm laser, orange acrylic in 3mm will give you ‘adequate’ protection from the odd stray reflection for diodes <3W, but there’s no...
More information needed - what its this 'arduino'? Can you not connect it physically to the wiring for the steppers and microswitches. Or can you...
