Looks cool... So when you going to try it? You probably have a dual holder for the Smartrap already designed up and your head and your fingers are twitching over your mouse waiting to put those ideas in to FreeCAD... I'll mail you a spare Jhead-Lite thanks to Regpye. Come on... You know you want too... I think I have some spare PTFE tube too...

Don't think I've seen a front to back arrangement before. Is the weight going to effect the swing arm any?

I don't think the weight would make a difference one way or the other. There are two of them no matter which way you mount it. But like Reg says - "We will see, wont we"
I think it will work just fine.

wonderful mark ! I'm so curious to see that in place
I'm thinking about where to put those 2 extruder steppers already
and what if we put 4 ? thinking hard here ..

Think I have about all the printed parts made. Center section and outer retainer for the second Hotend, the dual extruder extension and idler, and Bowden tube looms - 4 "dog bone" and 3 "C" type, for Bowden tube management.

Hmm, for some reason the Z axis is screeming especially during bedleveling. The small adjustments during a print are quiet.

Kits for the students to build, test, calibrate, print parts for another printer and then take the printer apart so that the next semester students can do the same thing all over again.

I have a few suggestions:

Why not let the kids keep the printer and also teach them to work with the printer and CAD stuff etc.
The printers keep evolving too, so just print new parts with the existing printers and this gives you a more recent model fort the next group.

To teach about tuning the printer Spectra line is actually great to teach about calculating to tune the printer. GT2 and R&P are simpler to set up, though in my opinion you would me missing an opportunity to teach a few valuable things.
You could also make a simple breadboard with RAMPS and a few motors just to teach about the firmware without doing harm to the hardware if there are adventurers who like to experiment a bit.

For the BOM.
You should be able to save some money on the PCB's
Also consider Regpyes Genie hotend and also his geared extruder.
I don't know if it is practical, but you can also build several types of extruders and again do some teaching on the tuning side of things.
you could also include a bit of bearing grease or use printed LM8UU bearing replacements

I assume the Ramps board included is pre-programmed to accept the new auto levelling setup but again I am unsure.

2) Do i need to put heat sinks on the pololus on the Ramps board? There were none attached to mine and none in the box that I got.
The reason I ask is because I can see heatsinks on the units that are shown on the Smartfrienz website but I would think that they would be part of the kit if I needed them.

3) What would you recommend to coat the glass bed to print PLA? I think blue tape ruins the finish of the printed parts and I know hairspray can clog up the nozzle.
Any help would be really appreciated.
Thanks
Mike

Hi Guys,
Maybe someone can help me with a few Smartrap issues.
1) Does anyone have any info about fitting the new J-head lite?
I just got my Smartrap through the post from Smartfrienz and there are no documents advising on how to put it together or adjust it. I assume the Ramps board included is pre-programmed to accept the new auto levelling setup but again I am unsure.

1. I think you have to flash the firmware yourself. you need to install Arduino for this.
2. I'm not sure if the heatsinks are really needed. With the 40mm motors i think you can do without.
3. dilute some PVA glue (woodglue) 1 part PVA 3 parts water and brush it evenly on the glass with a paintbrush. (Initially i had a woodglue that didn't stick at all) Now i have Bison D2 and that works fine. I also tried sugar, and that worked reasonable too. Hairspray didn't work for me Though i see MarkStephen has very nice results with Aquanet hairspray. (Unfortunately that stuff is not available where i live)
