Hi Shahin,

I'm so happy to show you the first print made with my top down, it is a holder for the servo motor, the resin is not the best and the Z resolution is only 100 microns, but the result is fantastic,
thanks Shahin, for your support, thank Nano dlp

Nice print and build platform

hello Shahin,

until now I used nanodlp with satisfaction, but today, when I finish slicing and I start printing, the system crashes,
attach the debug files, can you figure out why?

Thank you

Hi Andrea,

It looks like RPi itself has been crashed. It could be power problem or something similar which has not put any trace behind.

mandreas · 2016-05-21 15:02:04

Thanks Shahin,

I solved the problem by removing all profiles plate, and recreating them again, probably by importing them from the previous version, created some conflict,

Cheers ,Andrea

good result 30 microns, a few holes on the surface due to the imperfect model 3d, Rpb crashed 2 times, but I hope with the new PCB to solve...

Hi mandreas,

Excellent work, wonderful prints!

I can say now, that I've solved all the problems, and my "top down" works like a champ,
I added the shutter, and no more reported crash, in short, im happy, thank especially to the precious help of Shahin and his creating Nanodlp !!!

yonray · 2016-06-11 19:27:00

That looks great!

What are the use of the second box with built-in matrix lcd?

it is a power supply, step down, adjustable volts (24 to 5) that provides 5 amperes, powers the rpb and the servo motor

If you don't mind me asking, what are your settings?

Then, I used a "magic potion" a mix of advanced resins, 60 microns z, xy 67, exposure time 6 seconds

Hi Shahin,

I changed the micro SDHC card class 10 hc 1, but sometimes still happen blocks, attach the debug files, could you please help me? thank you

Hi Andrea,

It looks like rpi crash. Is the same source power stepper driver and rpi?
We had experienced same kind of behaviour with shared power supply, rpi is very sensitive in this regard

hi Shahin,

I tried with a specific power supply for raspberry, 2A , but the problem happens the same, I came back with step-down power supply, but I used a good quality cable 10cm long, the efficiency has improved a lot, no more crash a part one time , during the stepper movement that returned high in the post-exposure movement, I noticed on lCD, the amperage was stuck at 700 mA, as if , this movement, absorb much current from rpb...

How much voltage are you supplying to your setup? I read some where that if a supply of 5.25V is applied it will be enough to account for the voltage drop based on the high loads.

thanks very much yonray, I adjusted the voltage to 5.1 v, I do not want to overdo it and fry the RSB, it seems to run very well

You're welcome! I am glad I could help.

Never trashing old motherboards;) laminated plate copper on the RBI, noting the temperature, with the processor to 75%
