Steve, I have been following the progress on Demtris Ilios printer and have downloaded their Macro for Mach3 but so far I have not been able to get it to work.
I must be doing something wrong but I am not sure that he will be willing to assist me seeing as I have not bought one of his printers.
Perhaps I should ask him and see what he says.
I have also seen your blogspot about your printer project and am impressed with your machine and the good quality of your prints, well done!
Regarding using a ramps based controller like you mentioned, I am very keen to try that out as an alternative to Mach3.
Would you be able to give me advice on what I need to do to make a change to this system? I would be most gratefull if you could.
John, thanks for offering to send me your macro and outlining the procedure. I would definetly like to get a copy of it if you dont mind.
Maybe you could point out where I am going wrong if I need help.
I have uploaded a photo of my work in progress on my machine for all to see.
Greg

Basically it:
asks for the file name of the .pps file
Displays the firs slide (the blank one)
lowers the build platform to z-0
I have a shutter over the lens that I open here
Fills the tray with resin
Raises then lowers the tray to .1mm (my slice thickness) to get some resin under the platform
exposes the first layer
displays the blank slide
moves the z up then down for the next layer
exposes the next slide
then it repeats untill all layers are printed
It also exposes the first few layers longer to get a good base stuck to the plate
And it checks every 10 layers to see if it needs more resin
After the last layer it closes the shutter then raises the platform to it's full height and leaves the screen blank
I Dont have any commands to acuate a tilt mechanism because I went with a passive tilt. The tray is hinged on one side and free to lift on the other. As the z axis lifts, free side is lifted with it and provides the pealing action. It seems to work pretty well. You can see it in action here.
I din't have acces to the macro right now but let me know if you are interested and I'll send you a copy.
John

This is dangerouse, and doesn't occurr if the DLP windows is not opened.
So I've resolved adding the line
m_frmdlp.HideDLPScreen();
before
m_frmSlice.Show();
in row 728 of file frmMain.cs
Hope this helps.

Thank you for the great effort you have put into the program! (I have made a donation a while ago for the use of CW.)
I am using Mach3 as my controller and am able to run my machine using the G code generated by CW but I can't seem to work out how to get my projector to interface with Mach3.
I have Powerpoint installed on my PC but need some guidance on how to get Mach3 touse it.
I would really appreciate any advice you can give in this regard.
Thanks,
Greg.

sometimes, when print is finished a dialog saying print finished appears in the center of the vat
this may be gcode, change it to blank in the brackets.
why is always necessary to put the piece on the platform by clicking the "place on platform
If you scale or rotate the part, it repositions, a minor thing, but usefull.
sometimes happens that the platform goes down in the resin and does not return to the right position
Are your motors set up properly, does it only happen in fast traverse.
maybe someone with more experiance can answer better.

how you define the grid dimensions other then modifying resolution? I had to setthe resolution reducing the definition of the final image. can you help us?
sometimes, when print is finished a dialog saying print finished appears in the center of the vat, creating a big blob of resin if we don't stop it in time
the software after the slicing process projects the first layer on the resin even if the printer is disconnected (only projector connected), and does not wait for a command and we have to push the "hide" button to shut off the light.
why is always necessary to put the piece on the platform by clicking the "place on platform" button and does not do it automatically?
sometimes happens that the platform goes down in the resin and does not return to the right position, the light cures the resin without the object being printed, so we have resin blobs going around in the resin and landing somewhere on the object.
do you think to improve the visualization of the slices
thank you for your work, the software is very nice and the interface easy to use. The fact that all the operations (slicing...) are performed inside the same software is very useful. We think that we will keep using
bye Lorenzo and Gabriele
