nanoDLP

Hello,
It will be great (for those of us which use macro lenses) if there are software compensation of lens distortion.

Hello,
I have done settings of my Start of print section to ignore the initial M650 movement. After upgrade to the latest version 1165 it seems impossible - is this hardcoded? How to prevent moving up of the build platform before very first layer?

Hello,
It will be useful if there is a option to enable\disable home switch. I have a mUVe 3D printer and after homing procedure I am lowering the build plate about 0.5mm by turning the leadscrew by hand. My idea is to ignore home switch, go down 0.1 - 0.5mm below home position, set the new position as Z 0 and then enable again the home switch.

Hi,
Build 1149
The printer finished the print job but it seems the Arduino board stopped receiving commands from the Pi during print. Unfortunately I don't have a debug file after this failure but here are the log file after restarting the printer.

After a few restarts the printer start work normaly I don't know if this related to nanodlp or this is hardware issue?

Hi Shahin,
Are there any mask applied by default in nanodlp and how to check if the mask is actualy removed from the exposed layers? I am using a method to remove failed prints from the vat by exposing a rectangle at entire build area and when make a preview of layers I can see a mask  with dark area at the center of the rectangle. I hav removed the mask from "Projector mask" tab but it still persist in the preview even after deleting and reloading again the plate. Just to be clear, there are no mask in "Projector mask" tab, it is visible only in the layer preview. The nanodlp version is 1131, all the settings was restored. By the way this was my first test with new version and the printer freeze after first 90-100 layers.

Hi Shahin,
Is it possible to wire an additional servo motor to RPi and control this motor directly through RPi GPIOs ? My idea is to make a modified tilting vat for my mUVe printer which will be controlled by this stepper or servo motor. The other question is how to send G code for driving the motor. Probably I will need something like shutter open\close command just before start the default Z tilt lift after layer exposure.
