mnadamn's Wide MendelMAX 1.5 by mnadamn Nov 22, 2012

Description

*** Description ***
This is a wide version of the Mendel Max 1.5. The total build area is 12.6" x 8.4" and is based on the large MK1 heatbeds found on ebay. In order to handle the added width of the x-axis and the additional weight on the y-axis, all of the smooth rod has been upped to 10mm. Most files are from other thingiverse users (you guys do great work). There are still several parts which I was just not happy with so I have done those myself.

*** Updates ***
12/13/12 - Changed X Ends, added X Carriage, and added Top Vertex. Shown in pic.
1/09/13 - Beefed up X-Idler to add strength for Idlers moved further out. Changed Y rod holders to make construction easier and reduce possible binding. Corrected reversed face on Y motor mount. Also added the SketchUP build file.
1/25/13 - flipped mounting holes for the X End Stepper Motor
*** Needed ***
Fan mounts

How are you mounting the wider heated be to the rods. What about leveling adjustment of the bed?

This is what I am using. http://techpaladin.com/store/#...
Good luck with your build!

that's a cool printer. I m printing and sourcing the parts at the moment, with some modifications on Y axis (will use shuttle carrier, like on the 1.5+). One question: one lead screw nuts do you plan to use with the X-end?

Nice design, I think I'd like to give it a try. Do you have smooth rod measurements? I assume at a minimum the X rods will be longer than stock, by the same amount you increased the extrusions, but I wouldn't want to purchase parts on that assumption.

mnadamn on Feb 2, 2013 said:

Here you go, sorry I was out of town and didn't have access to a comp.. i could install sketchup on to measure. The dimensions are as follows and can be extended a little if you prefer. These measurements will leave little to no overhang.
X= 595mm

Y= 440mm
Z= 365mm

Then, since you used 90% of others work, and only 10% of yours, you should only get 10% of the credit, which wouldn't be enough to list it as NC, fair engouh?

mnadamn on Jan 30, 2013 said:

"Most files are from other thingiverse users (you guys do great work)." I have not claimed the credit. This is the printer which I will making for myself which is why my name is on it. The parts which I did are NC (x ends and carriage) as are several others from other thingiverse users. If others have it listed as NC I cannot control that.

I do not see why you are making this such an issue, if you would like to sell this as a kit you can go through the derivatives (all are listed) and download the parts and design the ones that are NC.

How can you take a bunch of files that are freely open, then put them under a more restrictive non-commercial NC license?

mnadamn on Dec 20, 2012 said:

Though most files are freely open, not all are. Thus the grouping of files as a whole cannot be.

Hello, could you tell me that firmware has been used for the mnadamn's Wide MendelMAX 1.5. Thanks a lot

mnadamn on Dec 19, 2012 said:

This is a hardware change for the MendelMAX. As such, firware would be based mostly on the electronics you use. You can use any firmware/electronics combo you wish that you would use with a prusa or MendelMAX based printer.

The only thing I have left is to work out the belt system.  The quick connect x-carriage designed by richrap looks great and I would love to use it but the belt retention points are off axis by an additional 7+mm.  I am working on a derivative of this which moves that connection to the traditional mounting point but that seems to either loose the belt adjustment or interfere with the release lever.  I am working on a solution to this problem and may have to switch X-ends as Jonaskuehling's will not allow this difference to be made up by sliding the pulley further down the shaft.  

mnadamn on Dec 19, 2012 said:

This has been corrected. I have updated the x-ends in order to allow the carriage to work.

This is awesome. I am Benjamin McDaniel, owner of Japica. This heated bed PCB was built specifically for my company, and I am glad to see its being used elsewhere. The "guy" on eBay is a reliable supplier and I can vouch that this PCB is great. My company would like to start producing a mendelmax extended version in addition to our already designed JapicaBot Extended, and I am glad to see that the design has already been made. Thanks so much. 

mnadamn on Dec 5, 2012 said:

Thanks for the kind words! The moment I saw that PCB online I knew I had to base my build off of it.  

mnadamn on Nov 22, 2012 said:

The heated bed can be found here.  All reviews of the seller through forums say that he is a great person to work with and has no problems answering questions if you call.  Be warned though He told me that it draws 14-15 amps.  Unless you have a 30 amp power supply you may need another.
