So I decied to start a new thread for my new build. As of now I’m going for a joker themed printer So it will be white, purple and green. It’s going to feature a few things different from my last build.
1. A frame made from 1/2 HDPE cutting boards
2. A Titan Aero from E3D
3. Printinz Zebra build plate
4. Rambo mini
5. Using “strap” parts to build the Final machine.
I did not document the “strap’ machine build but I will try to document the final build as best as I can and share the issues and fixes here with the group. Constructive criticism is encouraged. So If you see something I did wrong or have a better Idea please share.

Hi thanks for sharing. I’m about to start cutting my frame as well and will be starting a thread shortly. I had and e3d Bowden extruder that I was going to use on my AnyCubic I3 Mega but it wouldn’t fit so I returned it for a replacement of the aero like yours. I’ve been looking around for a x mounting system but they are all a bit smaller for the mp3dp (ie the distance between the rods is less). I read in your other thread that wanted to expanded the entire X carriage. Can I ask what you used to modify the stls?
Thanks R.June 10, 2017 at 9:52 am #35558
On the Titian Aero,
The good news it it weighs as much as a large body Stepper fully assembled.
And shows a decent weight savings over the MK8 fully
Hopefully I’ll beable to push this around a little faster than I have been with the standard setup.
The Bad, it wont really work with the standard mk8 holder.
This was my fist attempt to remedy to problem, but it has a small issue of the heat block being to close to the plastic, Sorry I didn’t take a photo of this. But you can see what needs to be removed form the x sled marked is sharpie.
This it for now, I’m going back to figure this out in a few hours, but I’ve got time on the Shopbot at the fablab so i’m running up there to cut the HDPE. Should have photos of that later tonight.

I used fusion 360. I have the x motor and x end stretched, but haven’t printed them yet. Trying to be sure this is the route I will go. I think there’s an easier path. And I should have that molded later tonight.June 10, 2017 at 10:19 am #35561
Cool. I’m looking forward to it. What is a “strap” build?June 10, 2017 at 11:10 am #35563Cool. I’m looking forward to it. What is a “strap” build?
Well i just tried googling it and could not find where i found it before.
But it’s when you build one machine for the purposes of build a better machine.

I just got back from the FabLab. Not sure that HDPE is the best choice for the XY frame or the y bed plate. I probably wont use the bed plate for sure, and just order an alumni one from Amazon, if I can find one that will work.
Notice the two holes that have a pocket cut out. You’ll need to do this ONLY if you are doing a 1/2 thickness build. It needs to be done so you bed level knobs dont hit the nuts. Make sure you mirror the pieces instead of a copy. That way when you you do cut it out the pockets face each other. I went 1/4 deep with these.
It’s dinner time, then I’ll get to working on the Aero mount after.June 10, 2017 at 5:13 pm #35571
Well it’s not the most inspired thing, but I think it will work.
I got it printing now. So we’ll know here in a little while.June 10, 2017 at 8:12 pm #35575
It probably would have been good to think about how I was going to slide the stepper in place…
Oh well nothing a little saw cant fix.
I’m going to call it good.
Now to print a fan for it…
Crap I forgot to order a fan…June 10, 2017 at 8:48 pm #35579June 10, 2017 at 8:57 pm #35580
How should the end stops be wired on the Rambo?
Right now I have it set on S and – on the rambo side. The wires coming off the two outer pins and the middle pin empty on the endstop side, and the motors will only move in one direction.
I haven’t flashed the MP3DP firmware yet. It still on the MPCNC firmware. Will that make a difference?

IIRC, the two outer pins on the endstops never connect. You want the middle one and one of the outside ones. One of the outside ones will be connected until you push the switch, which is what your firmware must be set up for currently. How are your other printer’s endstops wired?June 11, 2017 at 5:04 am #35596
I like that picture of the scale at 0.0. 🙂June 11, 2017 at 6:54 am #35602
I have them wired the same.
I can try switching the pins real fast as see what happens.June 11, 2017 at 7:26 am #35604
Switching pins worked.June 11, 2017 at 8:36 am #35613
Got the fix for the mount done. I don’t think i’m going to print it, but if anyone wants it just let me know.June 11, 2017 at 10:38 am #35616
Sure…I’ll give it a try if your sharing:). I started on an attempt to modify lone from TV but I’m not very experienced with fusion 360:(.

Are you using a short bodied stepper?June 11, 2017 at 11:56 am #35628
I’ve printed two fans ducts now and neither one of them work…June 11, 2017 at 12:08 pm #35629Sure…I’ll give it a try if your sharing:). I started on an attempt to modify lone from TV but I’m not very experienced with fusion 360:(.

Okay, Mine was 22. I’ll fix it for a 25.June 11, 2017 at 12:56 pm #35635June 13, 2017 at 4:28 pm #35851
HDPE is pretty close the the worst thing you could build a printer out of. I’m going to need to use jeffb base to stiffen this thing up. But it sure looks nice!
I’m I’ve been working on a part cooling fan. It’s being a bit of a pain.June 13, 2017 at 4:34 pm #35854
I like my HDPE, and it is thinner than that. Maybe a different material? for me it is holding up well, and machined really well.
Well at least yours looks nice.June 13, 2017 at 4:57 pm #35861
You made one out of HDPE? It did machine well. I think it’s really just that front and back panels. The stuff I got is very soft. It has a good bit of flex to it. Which i don’t remember HDPE being like that. It could just be the brand I went with.June 13, 2017 at 5:06 pm #35862
I actually have two of them the red/white and a black/white. It was the first cut I made with the LowRider cnc for the balck/white build. The red/white is pretty old. Maybe I got “starboard” brand but as far as I know it just means it has UV inhibitors in it.
The front and back do have some flex but you have such thick material it should not be an issue for you. I have 1/4″ HDPE and 1/4″ MDF and both have a slight bow but I haven’t added anything to them and the mdf is the weakest but also the very first one so it hasn’t failed yet. I can make a printed part that can strengthen them if you feel there is an issue.June 13, 2017 at 5:42 pm #35865
It may not be an issue. It might just be me putting more force on it than the printer will ever see. It it might actually suck up a good bit of the vibrations. Lets just see how things are when i get it up and running.June 17, 2017 at 7:17 pm #36221
Well.. I tried to up load the MP3DP firmware to the rambo… First I was getting some timeout errors. Then after a few tires it finally uploaded. Then I noticed nothing was coming across the LCD. Then A smell. I unplug it, plunged it back in and it smells again. Unplug it, upload the original firmware for the MP3DP, the one that’s still on my first machine. No difference, same thing, that smell. I look around and apparently something is telling my Heater cartage to heat up, and not just a bit, but like 700 degrees at least that was what S3D was telling me. It was burning a wire it was laying on while I was working on trying to get a fan mount for the aero. Any ideas what’s going on?June 17, 2017 at 7:42 pm #36222
Loaded the CNC firmware back on it. It’s working again. But it’s not the same. Not sure if I loaded the correct one. x works fine, y just makes a funny noise, like it’s not getting the power needed to turn, and only one of the z motors moves.June 17, 2017 at 8:33 pm #36223
Got it, I had to change the motherboard to rambo mini. Everything seems good now.
