ColorPrint App doesn't work  

Re: ColorPrint App doesn't work

I just used ColorPrint myself, worked ok for me? Your screen shot looks different than mine but I use a PC, I went to https://www.prusaprinters.org/color-print/
Is it different because of the Mac?

Re: ColorPrint App doesn't work

I have never been able to get the local ColorPrint Application to work correctly on a Mac. So I have always relied on the ColorPrint website for making color changes in my gcode. Unfortunately the website is now no longer working with gcode produced by Slic3r 1.39.2. Someone suggested using PrusaControl, in the mean time, but I haven't tried it yet.

Re: ColorPrint App doesn't work

I couldnt get the Prusa ColorPrint Webbased Version to work since Slic3r 1.39.2.
There is no local based ColorPrint I don't think
ColorPrint is intergrated into PrusaControl, I have been using that, works good.

Re: ColorPrint App doesn't work

A work around in the meantime is to add the M600 code manually. I search for ;{Layer_Height} and find the SECOND one that is marked as "AFTER_LAYER_CHANGE" in the comments. Then I skip all of the prep gcode and drop the M600 just before the first movement comment where plastic is extruded. The last command before the M600 is usually G1 F1500. Sure, it's a manual process, but it works just the same. Here's an example:

There is a local ColorPrint app, at least on a Mac (can't speak for Windows). If you re-examine the first post you'll see the OP is using it (and not the web version). Unfortunately it's never worked correctly for me. I'm not sure what is the point of including it in the driver package if it's perpetually broken.

I never noticed that! There's a "+" off to the side of the slider that adds the color change. Thanks!

Re: ColorPrint App doesn't work

Thanks for the tip karl.w2. I'll give that a try.

Yeah, I've never been able to get the ColorPrint to work on my mac which is what lead me to seek out a solution and find the website version. That version has worked for me in the past but has since stopped working.

I don't have a windows machine, but I'll see if I can get a friend to run the ColorPrint software for me.

Is there any chance of either ColorPrint being fixed so it works on mac (and so that the website works again) or at least having the software open sourced so it could be fixed?

@karl.w2, is what your describing what the software actually does? If that's it I could crank out an electron version fairly quick.

Re: ColorPrint App doesn't work

What Kark describes is pretty much what happens.

Be aware that the cimmand has a capital M and no gap between M600...

Also be aware that you can get false Z height indications... if Z hop is enabled.

Say you are using 0.2mm layer height. And 0.6mm Z hop.

If you want to invoke folament change at 1.0mm
You would expect to search for Z1.0
Unfortunately this can occur at layer heighr 0.4mm when there is a Z hop the Z height will show Z1.000

What I do. Is make the Zhop 0.62mm and search for Z1.00 this will avoid the Zhop error because the height with Zhop at 0.4mm will be 1.02
Which the search will ignore.

Also be aware. Marlin firmware causes a dribble of filament agter each M600 colourchange.
If you use your long nose pliers to grab the waste filament. BUT DO NOT PULL IT OFF THE EXTRUDER NOZZLE
when the lcd asks if the colour is clear. You click the button. The extruder then squirts out a dribble of filament before moving back to the print

This extra filament is pulled off the extrudwr automatically and does not end up as a booger on your print...
You can then throw away the waste in one piece
