Ok i'll have a play round with it, and see how it goes. But first I have to solve the top down lift sequence for my top down sequence with out reversing the Z axis wiring
At the moment I move the projector to the desired steps from zero, to set the different pixel size and build area, I then manually set the focus ring before printing at that tolerance, baby steps...
I'm using a ramps 1.4 and Marlin firmware, how would I implement the wiper on the x axis to run after the lift sequence before the next exposure?
I have my projector mounted on a Y axis rail above the build tank, currently I move it manually (number of steps from the bottom end stop) to control the pixel size and the build area, can this be added to nanodlp, so I can create buttons for a number of steps and label them with the pixel size and build area?
Can a wiper control be added, so after the dip and retract sequence (Top Down Printing), a wiper on the X Axis runs across the resin surface (number of steps field), with the added option of one way or a return trip tick box?
Is it possible to add direction control for the Z axis movement sequence (drop down box), so its easy to set nano dlp for top down or bottom up printing, as the sequence just in reverse?
Do you have a guide for setting up nanodlp with marlin firmware, for top down printing? I've look through this forum site without much luck, and I cant get my printer to [Print] - [Lower 5mm] - [Return less the layer height] - [Print]
Hi
I've built a top down printer and started using Nano DLP, I used to use Creation Workshop, but found it limiting.
But one thing I did like was the ability to simply select "bottom up"or "top down" from the setting screen, and then define the lift distance between exposures, speeds and dwell time.
Are you able to add this to your software and or a guide for how to do it, I have thought about inverting the motor direction in the marlin code, but this seems a bit of rough approach to take.
