    Hey there, great to hear that you've received your Palette! We don't have anything specific for the Robo3D R2 or C2, but we have some setup tips here: http://mm3d.co/p2-printersetup

    Also, if you're just receiving a GCode file, please check that you have a Palette profile loaded into CANVAS: http://mm3d.co/add-palette-profile

    The C2, at least, has Octoprint, so you should, in theory, be able to load the Palette 2 and CANVAS plugins and treat it as if it were a CANVAS Hub. I have a C2 but haven't tried this yet. I don't know about the R2. That said, Robo3D had promoted Palette+ as being compatible with the C2 and R2, so it should be doable.

    Jonny's "setup tips" link isn't helpful in explaining how to actually print with an "accessory" printer. I don't know if the C2 or R2 can be controlled by USB, having never used my C2 that way.

    Ok, tried the C2. I was able to install the Palette 2 and CANVAS plugins, link my CANVAS account and connect to the Palette 2. (I used the USB port on the back of the C2.) This seems to work in so far as Octoprint says I am connected to the Palette 2 and if I push the Clear button, the P2 clears its inputs.

    "Send to CANVAS hub" from CANVAS doesn't work. It asks me to select from two hubs, though the ident of the C2's is garbled, but nothing shows up. I downloaded the .mcf.gcode file and uploaded it to the C2. It does this, but doesn't display the Palette icon. Load and Print displays a message saying to follow the P2 instructions, but the P2 just sits there at the home screen. Meanwhile the C2 starts to print on its own.

    I'm not sure where to go from here.

    Steve,

    Can you give me step by step process to installing the palette 2 and Canvas plugins and linking it to canvas?   What exactly did you install the plugins into?   Of course it may not matter much if you aren't able to print anything.

    Yes, Ed's links are what I followed. I note that I wasn't able to update Octoprint itself - it claimed to be current, but I'm not sure. Once I loaded the plugins they did not appear the way they do in the CANVAS Hub, but rather as additional sections scrolling down on the main screen.

    Hey Steve, based on this information, we have a few questions and comments:

    • Was Palette plugged into your printer when trying to send the print file?
    • Did you try and control your printer from the screen or through OctoPrint? 
    • Could you please try and re-update the plugins? This may be an issue of the plugins not being updated properly
    • I did want to note that this is still experimental at this time as we have not tested much with printers that have OctoPrint already installed into the machine.

    Jonny,

    Yes, Palette was plugged into the printer (note that I said I was able to send the P2 a "Clear Output" command from the plugin.)

    I started the print from Octoprint, not the printer itself.

    I'll also note that, now that I have two instances of the CANVAS plugin registered with CANVAS (this naming is confusing!), CANVAS > Send to Canvas Hub no longer sends anything to my CANVAS Hub (attached to my Deltaprintr) when I select it. Instead I have to download the .mcf.gcode, upload it to the hub and print from there. It worked fine before I added the second instance.

    I am going to try to update Octoprint on the Robo C2 and will try to reinstall the plugins. It may be a few days before I get to this.

    Hi Steve, thanks for your information. Please let us know what happens when you have a chance to reinstall the plugins to your printer.

    Well, I was able to get a print started but ended up stopping it about 10-12 minutes into the print because the results looked like crap.  I think its the calibration for the printer that is off a bit.  I could literally see the filament coming out of the print head and falling on the print bed.  I'm guessing the print head is too high off the print bed.  going to try the calibration again on the printer and try the print again.   Anybody else have any thoughts?  I did take a few pictures of the results if anybody would like to see them.

    This would be the printer's own calibration. Which model were you using? The C2 has auto-leveling but I gave up on it and just do a manual leveling. You'll want to adjust the Z offset.

    I actually believe its because when I created the printer profile in canvas, I didn't enter a value for the Z offset.  I won't have a chance to check it until tomorrow but I think if I get that value from the printer or octoprint and add it to the printer profile, all will be good.   I'll report back when I have a chance to take a look at it.

    Well, I adjusted the z offset which seemed to be way off, btw.   Started a new print and it started out looking good, then everything suddenly detatched from the print bed and was moving all over the place so I had to abort the print.    According to Canvas the Print bed was supposed to be 60 degrees and the hot end was apparently set at 210.  Confirmed those settings on the R2 screen.  I am running PLA, so I think 210 is too hot for it and perhaps I should have changed it to 190.  Could this be why my project didn't stick to the bed?

    210 is generally fine for PLA and that's what I use. I don't have a heated bed, but 60 for PLA is ok. I would suggest redoing the Z offset and maybe increasing the first layer thickness to help with adhesion. I've had that sort of symptom when prints curl or the Z offset wasn't quite right.

    Well, given the fact that it seemed my print head was too far from the bed, I recalibrated the z-offset, then went to my printer setting on cura and grabbed the start and end gcode and loaded that into the Canvas/palette 2 configuration under the printer settings in canvas. Loaded a file, started a print and after it laid down the filament strip in the front (does this prior to starting any print on my R2), the printhead ground into the printbed and severely scratched my print bed.  I'm beyond pissed at this point.  What I have now is a $700 paper weight and I need a new print bed for my R2 because of this crap. 

    I realize its not practical to have a tutorial out there for using this thing on every printer, but the tutorials that are out there need to be better.  I've had this thing for weeks now and not one print.  Now I need a new print bed on top of all this.   NOT a happy customer right now.

    Hi there, I apologize for any inconvenience, but it looks like there was an issue with the Start/End GCode sequence that caused this issue. I believe you spoke to Michael Hackney about this issue: https://www.facebook.com/groups/mosaic.users/permalink/305847930051782/

    If you're experiencing this issue, please send us an e-mail with the start/end GCode sequence of your printer profile and we can take a look to see what is causing your extruder to perform this way (support@mosaicmfg.com).

    Need to provide an update here.  Turns out It appears the problem was the zoffset.  It was set in the printer settings in canvas and it shouldn't have been there.  I thought all printer settings needed to be copied over and that appears to not be the case.    Thanks to Michael Hackney and James Stevens at the facebook page they were able to figure out the problem.  Doing the keychain print now, so looking forward to seeing the results.  So far, so good.

    When I received my palette 2 pro, I got the 4 color calibration keychain print.  The print just finished but the colors aren't even there.  I set the upper right to blue, middle to white and bottom to orange.  It put blue in the middle, white in the bottom and then covered them both with the black.  As far as I know it never printed any orange at all.   I understand with the firmware update there was a 2 color calibration keychain.  Where can I get that zip file from?  I'm not seeing it anywhere and I don't have it after the firmware update either.

    The two-color keychain is https://www.thingiverse.com/thing:3301571  It doesn't come with the firmware.

    So, doing the 3 color lizard print now.  Using Orange, Blue and White for his eyes.  Palette shows 35 splices but everything printed is in orange. No blue used at all.

    Thanks for sharing this information. Based on the calibration print, it looks like the transition is occurring a bit too late, meaning the Loading Offset may be a bit off. I would check the steps here: http://mm3d.co/no-pings

    If you haven't done so already, I would also check the extruder calibration to ensure that your printer is extruding at a consistent rate: https://mattshub.com/2017/04/19/extruder-calibration/

    Well, The lizard print completed and isn't even remotely close to what it should look like.  I had it set to do orange and blue on the body and white only for the eyes.  Well, I got no blue on the print at all.  The palette indicated it was doing splices during the entire print, but all I was getting was orange before the white kicked in.

    Thanks for sharing, Roadrunner407. This looks like an issue with the Loading Offset, which is calculated at calibration. There should be a color change very early on in the print while a color transition does not happen until much later on your print. If you've already done an extruder calibration, I would check the loading of filament during calibration. It's important to stop loading the moment you see any color appear in the clear rather than waiting until a full color transition: http://mm3d.co/calibration-troubleshooting

    Another Robo C2/R2 user here.  My setup issues match what @Steve Lionel did.  While my Palette 2 shows connected, I am unable to start a print from Octoprint - it attempts to communicate, and says waiting to communicate with the Palette 2, but never is able to.  If I manually start a print on my Palette 2 Pro and follow its prompts, and then start the print on my C2, I was able to complete a calibration print, albeit without any pings being recorded.

    When the C2 shows it is connected to the Palette 2, I can select Canvas as the print source, and it sees the .mcf.gcode file that was uploaded locally to the embedded PI via Octoprint.  Attempting to select that files it fails, and forces me to restart the Palette 2 before I can interact with it again.  Canvas shows my C2 is linked to my Canvas HUBS, but is unable to communicate with the Canvas servers.

    Anyone have suggestions about getting the 2 devices to communicate?  I've made sure my C2 is updated as far as it can be - its a little troubling that while these printers were listed as Integration Partners, that there's no direct documentation to help us with these devices that feature built-in PIs.  I realize it is still very early on in this product's life cycle, and documentation is likely still in development, but I was still hoping for a bit more defined support.

    I'll note that the C2 and R2 were listed as compatible with the Palette+ - so it isn't just the P2. I'm thinking that the Robo printers work ONLY in Accessory mode, but I haven't tested that and am not sure how one drives the Robo printers over USB.

    TransBat,  I clearly share the frustration here  It's completely ridiculous that companies listed as "partners" and neither one has any idea about the other.   It's pretty clear to me that this partnership is on paper only.  I realize its impossible to test a product like this with every unit out there, but when you list them as integration partners one would expect that actually connected the two and printed with it.  It's pretty obvious they haven't. If they haven't even done one print with the two, it's false advertising to list them as partners and its basically just "assumed" they will work together and work together well.
