    The trouble for most with muti-color I believe is model building.

    Chicken and egg problem…. If everyone had MM printers, the files would be everywhere. It’s hard to justify the work if you’re making something functional though.

    I didn’t realize Marlin supported it. Still, I would expect some integration pains, but if you’re good at problem solving, I don’t see anything that would stop you.

    I remember when the Palette system came out. Hard to justify $800… I could have 1 or 2 more 3d Printers for that price.

    From what I saw on the Prusa upgrade kit it will jump to the next roll when it runs out.  Looks like its not readily available though.

    Are you applying the PEI sheet directly to the heated bed? I’m thinking about ordering 4mm Borosilicate Glass size 219mm x 219mm  and the PEI sheet. Would these work?

    Pei is usually sold with a sheet of double sided sticky stuff from 3M. With that, you can adhere it to either surface. If you have an aluminum heat bed, you don’t need the glass, but some people think it helps because it’s flatter and you can take it off. The glass also adds a barrier for heat between the heater and the pei, but I’m not sure how much it matters. You’ll probably destroy the pei before getting it off, so if you’re going to try both, you’d need two.

    I should have said when I ordered my last graphics display it was for my MP3DP. I think I have the firmware loaded and fixed this line for the display:

    #define

    REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER

    My display doesn’t have anything on it, but shows a blue screen but no text.

    When I connect to the Mini Rambo I get: Error:Printer halted. kill() called!

    It’s probably just wired wrong there are many ways to write it and they are all harmless, but only one way works.

    The screen doesn’t have any firmware you can change.

    Why is your controller running 1.1.5? Not your root problem but that’s a bit old now.

    The display was working prior to me messing with firmware.

    Can you point me to the right firmware?

    It is on github, you need to use the drop down to select the correct one.

    I think you need to remove u8glib from the libraries folder, but that internal compiler error is strange…

    That says arduino 1.8.8, you need 1.9

    I missed that part about using the beta version. When I try to move any of the AXIS it seems like they need more power.

    Seems?

    I am not seeing what board you have but the ulimachine boards have digipots in the firmware (or LCD adjustments) or regular will need manual adjustments.

    That should be fine for a printer. What makes you think they aren’t strong enough?

    #80838

    Ryan

    Your steppers will run best at 85% max rated or lower. I have never needed more than what is set stock for the printer. That is why I asked what you meant by “Seems to need more”? Are your steppers cold and not moving? If the steppers are warm, slightly above room temp after 20 minutes of continuous use, you should be close enough to the right current.

    If they are as cold as those granite slabs at cold stone, then check your thermostat. If they are hot enough to melt through the floor then you might have thermite motors instead of regular ones. It’s a sliding scale.

    What type of connector is used on the mini Rambo for the endstops? Dupont 1×3? These don’t actually have a clip to hold them in. I tried to do this with Dupont 1×1 but they just fall out. Argh!

    I run the steppers just hot enough to cook bacon…

    The connectors are Molex connectors with a latch. Note, they use different inserts than the dupont connectors.

    On these end stops, do I use both outside pins? Looks like the two outside pins are Common and NC.  When the end stops are not set open, if I issue the M119 command it shows them all triggered.

    #80868

    Ryan

    Correct for the MP3DP wire the endstops NC, and when not triggered M119 should say open.

    I seem to have the opposite when entering M119?

    You sure you flashed the MP3DP firmware and not the MPCNC?

    🙁 My bad! I will try the correct firmware tomorrow.

    I can finally go home!! All of the AXIS are working now.

    The Z seems quite noisy though. Listen/see here

    Maybe it is a rattle between the base and sides?
