    I have managed to cut each piece in one pass with my MPCNC. That sure does speed up the time it takes to cut each piece.

    Should I paint this? All my 3D printed parts are red so I was thinking about painting it black?

    This video is 1.9 gb so it might take a second to load. What do you think about the speed of cutting the entire piece in one pass? It starts cutting the part out at 1:30 of the 5 minute video.

    Looks good, I always use a finishing pass but other than that looks great.

     

    I think some sort of paint or finish is a good idea to keep the greasy finger prints off of it. One day you will get a clogged nozzle or filament jam and next thing you know it will be a mess.

    Paint is a good choice for mdf. It will go on quick and thick and protect it. Something glossy, what goes with red? Maybe black or gray or white? Superman blue to go with the joker v1 from fish tacos?

    What holds this rod in place?

    Gravity, it is a good way to tell when/if your bearings go bad. If you are nervous you can add a drop of Super Glue and it should not move.

    I guess neither end of it has a good enough hold on the rod so it falls out easily.

    Drop of glue is good, it comes off the metal just easy enough not to worry about it down the road.

    Will do. Some of these bearings don’t slide as easy as I would have thought. The bed takes a bit to move it. Maybe the bearing holder brackets are too tight?

    Yeah, very little pressure. I think I have a picture in the instructions. One side is flush and should be tight, the other side just needs a touch of tension.

    The Z stepper should keep that rod up, and gravity down.

    Now the bed is sliding along like butter. I switched back to the HeffePlate V2. What are the 4 holes in the back left corner of the plate?

    I put a little super glue on there. I will have to wait until it dries before I can test the movement out.

    Looks awesome! How did you paint the MDF? Shellac followed by black? Which black, that’s the finish I want for mine as well.

    Thanks! I used the ACE Hardware brand of spray paint. The nozzle on these cans are great. I painted these parts with 2 coats.

    I tried using the primer and then paint on another LowRider MDF piece but the MP3DP pieces turned out better IMO.

    Oh no the X carriage is backwards.

    I’m not sure I’m following.. Unless this isn’t the part you are talking about.

    That photo is taken from the back… Oops. Not a huge deal to fix.

    Yes it is. Ooops! I guess we will see how strong the little dab of super glue is.

    Thanks for pointing that out.

    Will these Nema17’s work for my Z Axis? I had these laying around. Might as well use them if I can.

    What are your thoughts on the dualmk8 extruder? I’d like to bring my 3d printing frustration up to a new level…

    My opinion would be to go bowden if you want to do dual, but do it through a single nozzle. See Me CNC and Prusa Research have the mixing bowden attachment, probably the usual places as well.

    So I’m just messing around with this X5 Mini on my MP3DP. I have the Z axis pins set to 1/32 stepping and 5120 steps per unit. (M92 Z5120.00) When I try to move it 1 mm, it’s actually moving 5 mm.  I’m not sure what I’m missing.

    I don’t know what an X5 mini is, but that is a ton of steps. Are you using a regular T8 leadscrew? It should be like 400, 800, or 1600 steps. I think 800 for 1/32nds.

    800 steps seems to be the magic number.

    Would this work with the MP3DP?

    It prints up to 5 filaments at a time.

    I don’t see why not. I believe all the code is in Marlin now, you just have to make sure your board has enough pinouts. There is also the Pallet system, which has one feature I really want. The ability to use up old rolls. when one runs out it will auto feed/start the next roll. The easiest way is two color through a bowden though.

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