MakerFarm Prusa i3v 10" - And So It Begins!

[tfast500]

First Thoughts:

Wow, this thing is off to a great start receiving it two days earlier than I had originally expected! Opening the box was exciting as always and the first thing I noticed and had not expected was a very organized placement of parts. The hardware, motors and electronics were all in separate containers, was accounted for, and labeled! The wood parts are solid and precisely cut. The wood is of way better quality then I had expected it to be. No cheap stuff here! So far this thing has me truly impressed. Unfortunately due to prior plans I was not able to work on it till later this evening.

So Far:

I have been off to a good start - I have completed the first 42 pages of the build guide (I opted out of painting the pieces and honestly I am digging the wood look anyhow). I have not gotten hung up so far because everything has been going perfectly per the instructions.

Here are some pics

Take your time - calibrate, calibrate calibrate

Yesterday:

I did not post my progress but I did make some I was able to work about 5 hours on the kit. I finished the frame, installed the heat bed, assembled the extruder and hot end (e3d v6 hopefully did it correctly), mounted the end stops, and spool holder. I also uploaded the firmware to the rumba board.

Feel like it is all coming together nicely. I am not happy with the glass though. I attempted to cut glass for my first time. You guys would laugh if you saw how horrendous it is.... I better just go to the glass shop when done. However it will have to do for now. I used tape to make it look half way decent for now.

Today:

Since I work a full time and have kids + a needy wife :P it is hard to find time to work on my projects during the week. I did get quite a bit of the wiring done this evening though. I can see the end of this build nearing and it makes me very eager to finish up. I need to purchase some spacers for my electronics and the proper size screws for my power supply tomorrow. I think within the next day or two I should have this build completed. And as adamfilip stated calibrate, calibrate, calibrate.

Issues:

-The belt on the Y idler bracket is rubbing not sure how to keep the belt centered. I am not sure if it matters?

- Cant figure out the best way to run the X end stop wires?

- I am not sure where the Y end stop needs to be placed along the Y Aluminum extrusion? Right now I have it so it will go the full distance of the aluminum extrusion right to where it will hit the bolt under the bed.

- The Glass is jagged and choppy on the edge I "attempted" to cut and all 4 corners

- I have a fan that I am not sure where or how it mounts. Possibly for a different hot end? The instructions do not say what its for and where to mount it. I will double check though.

- Although I haven't finished installing the electronics, it seems like I have a lot of wires and extra screws with the kit. (This never seems to be a good thing) :/

try and offset the gear on the stepper so it changes the angle of the belt slightly, hopefullly you can do it enough so it doesnt rub, rubbing is bad

- Cant figure out the best way to run the X end stop wires?
i ended up running mine on the left side by the stepper as i already had the stepper wires running, just had to reverse the direction on marlin firmware so it homes left instead of right

- I am not sure where the Y end stop needs to be placed along the Y Aluminum extrusion? Right now I have it so it will go the full distance of the aluminum extrusion right to where it will hit the bolt under the bed.
let the bed go as far as you can , until right before the wheels hit. plus leave a small gap.

- The Glass is jagged and choppy on the edge I "attempted" to cut and all 4 corners
I used a Dremel with Diamond Cut off saw blade. with some water and it worked great if you cut slowly

- I have a fan that I am not sure where or how it mounts. Possibly for a different hot end? The instructions do not say what its for and where to mount it. I will double check though.
E3D V6 has a fan with Blue clip that goes over the alum fins of the hotend.. look up the hotend it should be obvious. I would also recommend having a fan blowing on the board. as the stepper drivers can get warm and cause missed steps

- Although I haven't finished installing the electronics, it seems like I have a lot of wires and extra screws with the kit. (This never seems to be a good thing) :/
I had alot of spare motor wires in my set

Thanks for the wicked fast reply. This helps alot thanks!

Your X motor, will be moving up and down. You will need to leave some slack in the wiring.

The belt on the Y idler bracket is rubbing not sure how to keep the belt centered. I am not sure if it matters?

Like adamfilip pointed out, try to line everything up by sliding the bed forward to the idler and positioning the belts on the y-bed mount so the belts line up with the idler. Then slide the bed all the way to the motor and adjust the motor pulley so it lines up with the belt coming from the y-bed mount. If that doesn't fix it, the bolt holding the idler pulley might be a bit out of alignment. Experiment with loosening one of the idler bracket mounting screws and tightening the other. That'll make a small adjustment in how perpendicular the pulley bolt is with respect to the belt. At least a few have added a shim like a guitar pick under one side of the idler mounting bracket in order to adjust the bolt enough to keep the belt from rubbing against the wood side. Once you're printing, there are some idler pulley guides on Thingiverse that you can print and add to the pulleys to solve the problem.

I am not sure where the Y end stop needs to be placed along the Y Aluminum extrusion? Right now I have it so it will go the full distance of the aluminum extrusion right to where it will hit the bolt under the bed.

Remember that you're setting the y-axis home position with this switch. The 8-inch beds have a square silkscreened on them to "suggest" a printable area. You sort of have to guess on the larger beds.

If it makes you feel better, I've never been able to do good at cutting glass either. For those that have the right tool, the right procedure, and the right touch, it's apparently easy. I had my local Ace cut pieces to the square shape I wanted, and then used my tile wet saw with a diamond blade to angle the corners.

I have a fan that I am not sure where or how it mounts. Possibly for a different hot end? The instructions do not say what its for and where to mount it. I will double check though.

Speaking from over a year ago, I know the kits used to include an extra fan. And yeah, the kits used to also include a lot of extra wiring.

Thanks guys I will give these tips and suggestions a go and report back.

Tonight I was able to mount the power supply and electronics. I routed my power wires around the back since I did not have enough room to go up through the channel in the bottom. Looks pretty good to me. I am happy with the cable management so far.

Tomorrow I should have everything hooked up and hopefully be able to test and calibrate the printer I am pretty excited to see this all come together and hopefully work!

I must admit this is taking way longer than I expected to put together. Partially do to taking my time with everything. Also breaking up the build into stages.

After a a quick scare thinking my rumba board was shot. For whatever reason after first power on 10 seconds in, my whole board and display turned off. Checked everything with multimeter and everything looked fine. So after freaking out I decided to see what happens after completly unplugging everything. Thankfully this did the trick and the board powered up again... Something must have shorted it or plugged in incorrectly? Maybe just a fluke I am not sure but luckily everything is working now. My next issue was the hot end was reading 739 degrees... I took off hot end and moved the thermo wires and I gotto read properly at 24degrees. It must have been shortening out. Ran the sample gcode then printed my first knob for the display took two attempts first time the filament didn't start extracting right away so I restarted it. After the knob I made the maker robot... I have some quality issues I want to get your guys opinions on. I'll post pics tomorrow and see what you guys think.

Overall very happy with how and what it printed considering being its very first prints. It is only going to get easier and perfected from here once I get more experience.

[tfast500]

I have pictures of my first prints please let me know what you guys think. Where should I begin on tweaking things?

IMG_20151001_011743138.jpg

My knobs to try out for the display. Overall these turned out fine.

IMG_20151001_240613502.jpg

The base of the prints seem off. The bottom of the knobs and the feet of the robot have gaps not sure why this is or what is causing it.

Maker Robot - elbows drooping and feet bottoms are not good

IMG_20151001_011840397.jpg

Have you guys experienced these issues? I assume some supports under the elbows will fix the drooping, but let me know if you think it could be a temperature or speed or any other issue as I do not know what things can help at this point.

Currently its printing a vase and I see alot of spud on the edges any ideas on this?

IMG_20151001_105014306.jpg

Yes I know I am currently print happy right now! Lol I just cant stop printing stuff this is too cool!
