PrintrBot Simple X-axis GT2 Belt & Extension Remix by bringho Jan 29, 2014

Description

I had trouble printing the original PrintrBot Simple X-axis GT2 Belt & Extension (Thing 215294) on my far from perfectly calibrated Simple so I decided to remix it into something that would print without any problem on my standard sized bed before installing the Simple XL Upgrade Kit.

No design awards for this one, but if it helps anyone it's worth sharing.

The info you seek is in the instructions ;)

"ADDITIONAL PRINTED PARTS: 1 MotorMountXGT2.stl from Thing 194686 or 215294 2 BearingCap608.stl from Thing 194686 or 215294"

What did you use for the X motor mount? I don't see a part in the files.

I just measured my current settings and at 157mm z-axis elevation the screw that holds the top of the y-axis carriage (part 4) touch the 'LeftRail' of thing #242579 (my Adjustable Printrbot Simple XL Tower Filament Tray Expansion).

I could gain a few millimetres by lowering the bed. To get the full 165mm z-axis travel I would have to remove the Adjustable Printrbot Simple XL Tower Filament Tray Expansion.

Bringho, Where did your 5mm of y axis go? Does this steal some of that? BTW, the directions look awesome! Thanks.

My total build area should be X240 Y95 and Z165 with the XL Tower and original PrintrBot Extended Bed being used.

Unfortunately my own 'Adjustable Printrbot Simple XL Tower Filament Tray Expansion' (http://www.thingiverse.com/thing:242579)http://www.thingiverse.com/thi... steals some of the Z height (no more than 5mm though).

Possible print area is a different thing: X-axis length depends on what size bed and steal rods you choose. Those are not defined by this thing =)

Y-axis is 95mm at the moment. This will change to the full 100mm with new parts uploaded in the near future.

Z-axis height is roughlly 160mm with the XL Tower conversion and my 'Adjustable PrintrBot Simple XL Tower Filament Tray Expansion installed.

so what is your total build area now sorry if i missed it while reading

Enter the GCODE M503 in the Repetier software, if the response does NOT include:

16:00:20.557 : echo:Max position (mm): 16:00:20.557 : echo: M211 X240.00 Y95.00 Z165.00

Then you have to upgrade the firmware in the printer.

I used the instruction found on:

http://help.printrbot.com/Guide/How+to+Reflash+Firmware/78http://help.printrbot.com/Guid...

Then I could use the GCODE M211 X... Y.. Z... to set the new chosen build size.

Hope this helps.
