I guess I can say that I am addicted and the way to avoid a divorce is to keep making things for my wife. How can she be mad when I give here things?

Oh and I have at least two of everything on the list and still have a wife.

And a slate coaster made on the K40

My glass is always half full (usually with Bass Ale) -- it was a good excuse to buy another bigger machine.

It's focus is on CO2 laser's looking to replace things like RDWorks and LaserWeb, but will work with any GRBL or GRBL-LPC machines. But beware that the default for setting speeds is mm/sec not mm/min like most of the software for diode based laser.

There are still quite a few growing pains - but I will be using a lot soon instead of RDWorks because I don't expect T2 to ever support RuiDa DSP controllers which is what my new machine has - it's replacing my K40 that went up in smoke with a big bang. High Voltage fault melted the pins off the high voltage FET's and make the whole PCB black with no hope of saving the power supply.

I take the Ceramic coat off all the time with a CO2 laser, but the diode laser won't touch it.

Rumor has it Wild.Bill has 3 of every toy (tool) ever made.
No - I am down to only 1 CNC after taking the second one apart for parts.

But on the serious side - one need's do decide what they want to make and then choose the proper tools for the job. And sometimes it takes more then one tool to fill the needs.

It depends  on the material you work with. A K40 will etch ceramic tiles and clear acrylic where the diode laser will do nothing. Other things having more power means you can work faster. It really depends on what you are trying to do. Ideal is to have both.

That too bad that you put the wrong logo on it.

No offense. I live in Minnesota, so this Super Bowl sucked for me
I like football but don't live by it. It was a good game with interest from start to finish and the team that played better won.

I'm just glad I didn't print the one's that said CHAMPIONS.

Ready for the game with new slate coasters

Trouble Shooting / Cohesion/GRBL-LPC - not etching image
« on: February 02, 2018, 09:39:10 AM »
To start I am doing this on a K40 with the Cohesion controller loaded with GRBL-LPC.
Postprocessor chose Cohesion & GRBL, & max/min are set to 1000/0. This requires S values from S1000 to S0.

Problem 1:
Trying to etch any grayscale image at 400 -> 40% of power.
On the control page I can manually turn the laser on and off, and I can outline the frame with the laser on. When I run the image the head moves but the laser never turns on.
I have been able to make grayscale images on this hardware setup using other software
and have done grayscale with T2 on the hardware using Smoothie firmware in the controller.

Problem 2:
I tried to save the machine G-Code but I can't see if/where it is being saved. I was going to try to debug the problem but without the G-Code I can't see what is being sent to the controller.

The birch that I am using is cut into 6"x6" pieces.
What you don't see is the huge stack of wood that got dumped before I started getting good images.
LOTS of trial and error.

Attached are the before, after, and Photoshop screen showing the curve used.

It is on the K40 with a Cohesion Mini board/ Smoothie using grayscale. I need to also add that I am applying a Photoshop curve to make up for the non-linear laser.

The "L" signal which drives the laser is PWM. Still learning the details of the
board but I "think" its being driven via a FET pulling the signal to ground.
It's NOT TTL but is used with a PWM signal the same way.

It's a big learning curve with Smoothie - much like when I was learning the Arduino/GRBL
controllers. I am digging fast and deep because my next Cohesion Mini should be here soon
thats going on the ACRO system - and it looks like I will have to write the first guild for doing it.

Yup -

I started having a problem with an X shift tonight with the K40 - that I will have to fix. Here is the latest grayscale that does have a shift in it. I wounder if there is a message in this image?
