Z-Endstop Position in NanoDLP configurable?

ToS · 2017-10-22 14:52:54

Hi there,

nanodlp seems to be expect the endstop positioned at the top of the z-axis, which basically considers it as an max-endstop.

Is there a way to configure nanodlp in a way so that the z-endstop can be mounted at the bottom as kind of min-endstop instead?

This seams to make more sense to me, as it's more critical to crash the z-axis into the display but driving it to the upper limit.
Also wiring of the endstop switch at the bottom is more easy than at the top.

Maybe I missed an importand argument or it's already configurable in the mentioned way.

Any tipps and arguments are welcome
Regards
ToS

To the best of my knowledge the end stop position ( max or min) are configured in the control board firmware Not in Nanodlp .... As are the steps per mm, homing direction etc etc

There is no control board firmware as I indent to use raspi GPIO's

Bottom limit switch control is under development. Scroll to the bottom of this page and you will see it listed under "high priority" https://www.nanodlp.com/

It is already available on latest versions.

@Shahin: Thanks! Really appreciated. ...but downloaded and tested it today and it either doesn't work for me or at least not as I expected:

When I go to "Z Axis Control" and press "Calibrate Zero Position" the motor starts, but doesn't stop when the bottom endstop switch is triggered.
Same with "Measure Z-Axis length"

Is it working for manual movements?

@Shahin: not quite shure how to interpret your question

Move it down until it reaches limit switch at bottom. If it passes, it does not work.
