Well I have no idea checked the end of each gcode set, one had a blank line at the end. but still getting the same thing.
Like you say, does not effect the running it is just frustrating knowing it ain't broke. But something is not right and you have no idea how to fix it
Thank you
jamesarm97 for your suggestion
I deleted all as you suggested in the resin profile and in the machine set up.
but unfortunately I still get the same message just it does not have the comments any more.

I have checked everything I can but still keep getting the same error, I have even re-flashed the D7 with the latest firmware.
But still getting the same thing. is there any way to monitor the actual traffic that is going to and from the Pi and the printer in the terminal.
Tony
Thank you for that I will have a look next time I run Nanodlp I have my setup in pieces at the moment having to re-organise the mess
Tony
Hi
I get this message in the terminal while nanodlp is running, and I can't find where the command is that is being sent, and causing the message.
Nanodlp and the printer seem to be working OK, would just like to find what is giving the message.
The printer is a Wanhoa D7 with Nanodlp build 1744 running on a raspberry pi, I have no idea how long this has been happening.

I thank you for the supplied information, have to say it makes my brain hurt, I will try this out next time I have no resin in the printer. And will attach a dial indicator to see what happens, as the only way to see the set height is in the log file.
@Shahin Would it be possible to show the current absolute Z height with the layer number, and the current layer step size.
Thank for that, I now know that it can only evaluate one condition in a statement, and not multiple as in normal programming.
does this type of coding have a special name and is there a reference source for it to learn more about it.
Cheers
Tony
Thank you for that,
{([[LayerNumber]]>30)*50+40}
Something like above will cause 90s cure time for layers after 30
Unfortunately this only shows how to use dynamic cure times without dynamic layer heights
I was having a play with the boxes to try the formulae and found it would not work with a formulae containing thus ((4<[[LayerNumber]]=>30)*40)
(
(([[LayerNumber]]<=4)*90) gives me 90s for layers 1 to 4
+
((4<[[LayerNumber]]=>30)*40) gives me 40s for layers 5 to 30 ##### this line does not seem to work as someone has mentioned in another post ####
+
(([[LayerNumber]]>30)*20) gives me 20s for layers 30 and above
)
Or do I need something like
(
(([[LayerNumber]]<=4)*90) gives me 90s for layers 1 to 4
+
(([[LayerNumber]]>4)*-30) gives me 40s for layers 5 and above
+
(([[LayerNumber]]>30)*-20) gives me 20s for layers 30 and above
)
So I would end up with
layers 0 to 4 90s
layers 5 to 30 40s
layers 31 to top 20s

An example of what I am looking at and why is I have a model that has a support base 1mm thick supports are 2mm high and model is 4mm high.
This is a 1:76.2 milk wire crate I have successfully printed it on the CTC riverside which is the Form1 clone with the Laser. But I cannot print it on the D7 as there is not enough power for the 0.2mm sections.
0 to 0.4mm burn in at 92.1 seconds layers 0 to 4 at layer height of 0.1mm
0.5 to 3.0mm 40 seconds which is rest of support base and the supports layers 5 to 30 at layer height of 0.1mm
3.0 to 7mm 90 seconds which is the model model sections are 0.2 mm square section layers 31 to 191 at layer height of 0.025mm
As I said before I need to make up for the lack of power to cure the resin so if I can use thinner layers for the needed layers then I can make the model above.
At the moment you can make the burn in layers one cure time and the rest of the model a different cure time, But I am greedy I need more layers I can set different cure times and thicknesses.
I would be using known cure times as like you have listed, so I cannot see this causing any problems.
Yes, we have dynamic cure times but it mostly being used for support layers but you can use it together with nanodlp formula support to achieve dynamic layer height.
Would it be possible then to give me an example of how I would achieve this, ( I am having trouble getting my head around the syntax used in these formulas,)
I have been spoilt with the programs for FDM printing
Thanks
Tony
We made couple of attempts to add this feature to the program. Software implementations is easy but as cure time for resins are not linear and each height have different optimum cure times. Having different cure times on different layers will result surface quality issues. It will be very difficult to come up with perfect cure times. Also in some cases all lift and other movement configs need modifications too.
I am a bit confused with what you are saying here
Having different cure times on different layers will result surface quality issues. It will be very difficult to come up with perfect cure times
Because dynamic cure times is doing exactly this is it not. So where is the difference in regard to the curing of the resin, between dynamic cure time and dynamic layer thickness.
Once your have found the ideal cure times for the particular resin would one not use these in the formulas. the dynamic cure time and dynamic lift would have to be related on each level as it is now with just straight printing.
I have a Wanhoa D7 and it is incapable of printing the detail I am trying for because of the low UV power. So I need to be able to apply more UV to these layers to get the detail. One way is dynamic cure times but also thinner layers also would help to cure these parts.
Tony
I was wondering if it is possible to do dynamic layer height. The reason being is I come from using FDM printers with Simplify 3d which I now use for my CTC Riverside SLA printer.
With that software you can set any parameter to change depending on the Z height you are currently at.
One feature I use in every model is the ability to change the layer height depending on the Z level in the model, ie
For the lower levels with no detail you could use a 0.1mm layer height making it quicker and then for finer detail change to 0.05mm then to 0.025mm for very fine detail, then depending on orientation of model could go back to 0.1mm.
I currently do this with Simplify3d, so you can speed up the printing process by only using high resolution in the model only where needed.
Cheers
Tony
