Not yet- i'm still testing the hotbeds. I didn't receive all the parts yet, so this weekend i'll only get to assemble (today) / test (tomorrow) the power supplies and motor drivers. Hopefully Monday or Tuesday I'll receive the missing bits to complete assembly. I'm also finalizing the assembly of my beautiful new Hadron :mrgreen: and sorting out the extruder and calibration this weekend so that's about all the time i'll have anyways, quite a lot to do already ;)
Does the board have components on both sides. The silkscreen suggests that.
Nope. not sure what feature makes you think so - maybe some of the optional through-hole parts (connectors).
The SMT terminal block headers were backorder so i made those into through-hole pads for the protos only, so i could use either if necessary.
From the picture the quality of the silkscreen and solder mask look very poor. Is it just the picture?
Actually the silkscreen and solder mask are top notch, if they look fuzzy its just the picture - taken from my new android phone. i used to have a proper digital camera but it crapped out on me some time ago.

I saw how you connected the designators like this, but some were harder to figure out. The white lines looked fuzzy and the green masked looked like it covered some pads. It could just be a reflection.

The key to getting really good shots with an Android phone:
1. Rest the phone against something to eliminate jitter
2. Use plenty of light at an angle that won't cause bounce back
3. Touch the center of the screen to focus before taking the shot
4. Try out Camera360 and set it to Enhance mode or HDR mode and see if it works out for you

Oh. I *love* blinkenlichts, so that's too bad, but i completely get the reasons. A) no space, B) no pins, C) LCD, right?

Ah. Didn't realise the MOSFETs were to-ground.
Makes sense now :)

Me too - you should seen some of my earlier demo boards, like the bluetooth to serial interface i did about 5 years ago- *all* the serial interface signals and BT status lines were connected to different color led's - it looked like a little tiny Christmas tree blinking away when in use ;)
Anyway i lied, i forgot about the LED on the power supply :-)
Also, dont forget, i did provide a tootenhorn, so it makes up for it a little :lol:

What is the clear advantage of the ORDuino, compared with RAMPS 1.4 stack?

My goal is hires and fast printing, to make it short.
To do this, I only can see powerful MCU, and optimized firmware.

Tootenhorns are appreciated too, if blinkenlichts aren't present :lol:

Goodness gracious, great balls of solder!! its alive!!!

ORDuino bringup testing in progress...


So far, everything i've tested works perfectly, better than expected:
I've pushed the motor drivers up to 28V and 10A (for about a minute) and they didn't complain, didn't even trigger thermal overload. Don't try this yourself, you'll blow the fuse before you get there. i had to bypass the fuse to do that.

Getting ready to load and try to run the full printer firmware in the next 24-48 hours, as soon as time allows...
i'll even try to get a video up this weekend if i can :)

Damn kid, you soldered that yourself?

Impressive!
