Discussions about a RepRap for the space resulted in the conclusion that for maximum durability we should build a Mendel Max.

This is the hackspace mendelmax. It is the oldest of the printers in the space, and as such is very dead.


Please consult with Martyn before ordering/purchasing any parts.

The Space MendelMax currently requires :
This printer needs a LOT of maintainence.


* Motors - 5 needed for single extrusion, 6 if we go fancy dual extrusion - [http://www.emakershop.com/browse/motors eMakershop a possibility]
=== Z probing ===
* Smooth Rods - Metal Supermarket, all 8mm we have decided
* Electronics - SmoothieBoard or 4Pi arm-based electronics are ideal, but mostly only about to be released
* Timing Belts - Need to look up the specs.
* Extruder/Hot End - Martyn has a spare heated nozzle ready, we need a ceramic spacer.
* Heated bed* - Maryn has got a slightly iffy quote from china (direct import) for $45 each for 2 with $40 delivery.  Alternatively part no. SRFG-1212/5-P-230V from http://omega.co.uk
* Possibly some more LM8UU bearings


(*)A heated bed is not strictly necessary for PLA but makes it a lot more reliable, and essential for ABS
The Z axis endstop is shot. Not because the switch is borkned, but because the original design uses a screw, which will then angle itself out of the way, causing un-reliable Z-Homing.
 
The printer is also from a time before bed leveling. So there are no leveling screws to even manually adjust.
 
The solution: Use Marlin's Unified bed leveling, with a bed probe.
 
Current candidates include:
* A BFP Touch, basicly a custom built BLTouch [https://www.thingiverse.com/thing:2890290 Files here]
* A BLTouch
* A capacitive probe
 
=== Toolhead ===
 
There is currently a discusion about what to do with the tool cariage. The X axis terminations need to be reprinted, that is certain.
 
What is uncertain is if we should model our own cariage system, that is vertical instead of horisontal.

Check the hotend on the mendel max. Some say it takes 3mm filament. Others say it takes 1.75mm filament. Nobody knows, as it's been dead for a year.

Try and make tool heads swappable. Why? A: Because we can do larger nozzels, and B:Because it is possible to get 3mm fillament for ~£8 shipped from ebay. Will it be the most reliable? Frack no. But given the volume of the printer, having an E3D volcano (Real, diy, or clone) with a 1.5mm nozzle would allow for the maximum usage of the print volume. It would also eat material like nobodys business. So having cheap material seems like a good plan.
 
Why try to print so much material? Because singlle print props (Helments, model weapons, etc.) sounds like an awesome thing. If it doesnt take 2997923...hours to actually print them.

This is the hackspace mendelmax. It is the oldest of the printers in the space, and as such is very dead.

Maintainence

This printer needs a LOT of maintainence.

Z probing

The Z axis endstop is shot. Not because the switch is borkned, but because the original design uses a screw, which will then angle itself out of the way, causing un-reliable Z-Homing.

The printer is also from a time before bed leveling. So there are no leveling screws to even manually adjust.

The solution: Use Marlin's Unified bed leveling, with a bed probe.

Current candidates include:

  • A BFP Touch, basicly a custom built BLTouch Files here
  • A BLTouch
  • A capacitive probe

Toolhead

There is currently a discusion about what to do with the tool cariage. The X axis terminations need to be reprinted, that is certain.

What is uncertain is if we should model our own cariage system, that is vertical instead of horisontal.

Current hotend

Check the hotend on the mendel max. Some say it takes 3mm filament. Others say it takes 1.75mm filament. Nobody knows, as it's been dead for a year.

Future

Try and make tool heads swappable. Why? A: Because we can do larger nozzels, and B:Because it is possible to get 3mm fillament for ~£8 shipped from ebay. Will it be the most reliable? Frack no. But given the volume of the printer, having an E3D volcano (Real, diy, or clone) with a 1.5mm nozzle would allow for the maximum usage of the print volume. It would also eat material like nobodys business. So having cheap material seems like a good plan.

Why try to print so much material? Because singlle print props (Helments, model weapons, etc.) sounds like an awesome thing. If it doesnt take 2997923...hours to actually print them.

Safety Testing

The printer has a 230V silicon mat based heated bed, that has been sandwiched between the metal. It could probably do with an insulation test at some point.
