SLS4All - Affordable SLS 3D Printer

I changed the fans setup for electronics cooling yesterday. Now, three 40mm and one 80mm fan push the fresh air into the topFrame where is all the electronics. Two 80mm fans are then pulling air out of there. Before, all 80mm fans were pulling air out.

I did some testing yesterday and it behaved now much better. I heated up the chambers to approx 145°C, stayed on this temp around 2 hours and the electronics is still alive :-)  I measured temps on main components and they were more than OK.

Just hope it keeps cool enough also with halogen heaters on.

Here is for fun an old video showing the real beginnings of putting things together - FW modifications, SW development, etc.

Here it was for the first time when FW and pieces of SW run on Raspberry not PC.

I will share more of these in coming days ;-)

I am currently making some complex tests of the printer. It means I test it with the laser "on", burning the paper to see how it performs.

I am also trying to find maximal print speeds, and it requires some Klipper FW tweeking. Current max. speed of print moves is around 900mm/s. This is where I want to be, but still have minor stability issues.
