T MAX
Derived from
Description
The T MAX uses all the same major components as the MendelMax. If you have a MendelMax, it can be easily converted to a T MAX; or assemble a T MAX from a MendelMax extrusion and hardware kit.
The T MAX is design for use with Igus pillow block bearings, a RAMPS controller, and a common ebay 12VDC, 30A power supply.
Instructions
Special instructions:
Drill two 6mm holes (140mm apart, symmetrically from center) on the top two horizontal aluminum extrusions.
Fasten the bottom of the vertical extrusions using 40mm long, 5mm bolts and 15mm OD washers (3/16 X 1-1/2 stove bolts will also work). Don't forget to tap the holes to suit the bolts used.
Run the bolts throught the whole cross-section of the horizontal extrusions. This will add greater stength to the assembly.
The higher Z axis will require a pair of longer thread rods, 400mm.

Would you mind uploading the upper and lower z in a 10mm smooth rod form please
If you are using a different size or type of bearing, depending on the parameters of the bearing, many parts of the X and Z assembly may need to be changed,
Sorry, but I have no plans to adapt the T MAX to other parts that I am not using. No way to proof that the new parts will works.
I like the design but I don't think that the z threaded rods should be confined in 3 points: motor shaft, end and just above the coupler. Unless you have super straight threaded rods, you'll have z wobble. Its best to take out the additional constraints.
Each Z thread rod does indeed only have two restrain points, one 608 bearing at top, and the Z motor flex coupling.
Sorry about the confusion with the naming of one of the parts: Z THREAD ROD BEARING MOUNT BOTTOM. This part has only a pass through hole for the thread rod and does not mount a bearing. The part came from another printer design I was working on.
Nice design. I'm working on a design that is on a similar path with a T/I shape but longer on the X axis using sliders. Would you have any objections if i use the same measurements for the top Z mounts along with the same height for the lower frame section? I can see there being an advantage to get a standard size for this design the same way the Mendel Prusa's and MM has.
Hi,
nice design. I'm planning on building one, instead of a MendelMax.
I'm currently figuring out which plastic parts I have to have made, and how many of each.
Can you adapt the filenames of the stl-files, so they have the amount of copies needed included in the filename? This is the case at the MendelMax, and helps a lot.
Keep up the good work, and I'll send you a photo once I got my T Max up and running!
Thanks. Looking forward to see your build.
Here is the quantity list of parts:
4X LOWER CORNER BRACKETS
4X Z COLUMN FILLETS LEFT
4X Z COLUMN FILLETS RIGHT
4X GT2 BELT CLAMP
8X ROD CLASPS
2X X ROD MOUNT BOTTOM
2X Y ROD MOUNT
2X Z THREAD ROD BEARING MOUNT BOTTOM
2X Z THREAD ROD BEARING MOUNT TOP
2X Z MOTOR MOUNT
All other parts, one each.
Awesome design! I was wondering: What's the spacing between the threaded and smooth rod for the Z axis? (distance between the 2 inner edges)
I have a half built MendelMax that is now going to be a T MAX. This design makes more sense.
Very nice design, I like that you are using igus pillow blocks.
Which extruder/ hot end would you recommed?
Hi, like the design. The nut traps on the X axis, for the Igus bearings seem a little large. Are they SAE or Metric? The parts are printing perfectly, hope to have one built by the end of the week.
Thank you

Very interesting design and I am thinking about giving it a go but I have a few questions firts:
1)What is the new build height. I know that this is dependent on your specific combination of build plate and hotend but what improvement were you able to see?
2)Was this designed in Alibre or Solidworks? If so, could we also get the source files (.STEP, .SAT, .SLDPRT, etc.)?
Thanks much, look
s great!
You rock! Thanks for getting back to us so quickly! Wouldn't at all be surprised if this becomes a very popular build!
Maximum build height is 235mm.
That is assuming that the hot end extends less than 45mm below the bottom of carriage, and no portion of the extruder, 30mm above the top of the carriage, is more than 120mm wide front to back.
With most configurations, you can get the full 235mm build height.
STEP files are uploaded.
Please could you ZIP up all the files, this will make it easier for those of us who do not have broadband, yes still in 2012 this is the case!
Many thanks and I want to build a T Max!

Awesome design! I am making a plan to build this. Is the distance between the upper and lower frame assembly the same as in the Mendel Max? If not, what is the new measurement?
