awesome! thanks!
Where does one specify the Gcode to use before after layers?
you can specify that under each resin profile...
hello ionel.ciobanuc ,
can you please share how to edit setup_config.html in order to manually change pins used.
I already soldered my servo to GPIO to pin 21 before I realized it wasn't an option in the dropdown menu..
thanks!
I have been playing with my printer setup for the last week or so, trying to hook some peripherals to I2C pins such as an LCD display of air and resin temperature.
Today I boot up the pi and can no longer connect to the printer...its just gone. If I log into my router and check connected devices, I can see the pi briefly connects and then drops out.
I figured it must have been something I did, so I reimaged raspbian jessie lite, updated and upgraded the distro, and then re-installed nanoDLP.
I did all of this over wifi and SSH through putty....so I know the IP is correct.
after install and reboot I have the same issue, can no longer see or SSH or ping the pi.
I hook up a regular monitor and see the regular raspbian bootup stuff, then the screen goes blank...and I can never connect to the pi in any way.
Im really baffled on this considering it was working so well all week...
I also tried a second RPI3 with the same result.
I have no idea what to do to troubleshoot this at this point...any help would be appreciated!
thanks!
I see, well is there a limit to how large of pixel size you can use?
With the projector you bought, if you wanted to print at 150 micron XY resolution, would it still work? I understand there would be a trade off on the fine detail you could achieve on the finished part, but if you wanted to print larger, less detailed parts, would you be able to? Would you have to increase cure time with pixel size? or would it no longer cure properly as the pixels get too large?
thanks
Hey very nice looking results! congrats.
I am building a very similar printer, looks like you are using the sparkfun easy driver...is that right? Do you use endstops?
thanks!
sorry, there is some confusion...I am using RPI3 and direct control ONLY
Like I said though, I am doing top down style printer, I added an endstop at the top of the resin vat. When the printer powers up, the build plate moves to the endstop correctly, and then moves to the "platform wait position" (10 mm down into the resin). This is what I would expect, but when I start a print, the tray moves all the way to the bottom of the resin tank and then starts moving back towards the projector (up) with each layer...
Seems I need to flip the build direction around. Is there anyway to do this in software? I don't want the home position to be at the bottom of the tank...it would make for a lot of unnecessary travel...
build area ranging from around 50-100 microns
do you mean individual pixel size of 50-100 microns??? If not I am completely confused...
Hello all,
Just finished building my first DLP 3D printer! It is a top down setup with a 1024X768 projector, using direct control from RPI3 and sparkfun easy driver.
I have built several marlin/RAMPS/RAMBO FDM 3D printers, so I have a reasonable grasp on most things 3D printers.
What I am wondering is, if you are using direct control through GPIO pins, is there a way to use GCODE commands? it seems like that is only if you are using a marlin board after the RPI
One thing I would like to do is be able to issue a command like G92 Z0;
to tell the nanoDLP web browser interface that the build platform is now at the zero position. Is this possible? Right now I don't have endstops, so I would like to manually zero the step count...
If I do add an endstop, and I have a top down printer, would the endstop go at the top of the liquid where the build starts, or at the bottom of the resin tank?
thanks for this great software!
