Folger Technology Kits (Page 1 of 3)

I have not ordered any kits from them but did get a bunch of components and they are quite nice.  If you decide to get the delta printer kit and need help assembling I can provide assistance.

Thanks good info to know. I did not see that.

On the recommendation of a friend/acquaintance that is a 3d printer and filament dealer I use glass. I have been using it for 6 months and it works well for me.

Great looking forward to the results of the build.

Since I have posted this thread I Downloaded . the assembly  manual for the Kossel and the prusa I3 . 
the manuals look pretty decent. The kossel definitely seems better built than the I3. the kossel has linear slides rather than rods and the linear bearings on the I3 appear to be lashed to the platform with wire ties. HMM.
Anyway back to the delta. I have read some on line threads and articles about delta printer
DOWN side is inconsistent  results depending on where  you are on the build plate. Not sure if this is a issue of build quality IE improper arm length or inconsistent arm length or a software issue I know the math is more complicated with deltas. Also the seem to have a reputation for harder to calibrate and maintain. These are not a good choice for a bed full of small parts.

ADVANTAGES  smaller footprint. faster print speeds  due to lighter  print head.  Fun to watch. well suited to vase and bottle shaped objects.
Thanks for the info.

Looking at the assembly institutions the delta almost looks easier to build. But I have read harder to calibrate.
I cant quite wrap my head around the math that makes the delta work . The Cartesian plane I understand.

I was a little nervous about the Prusa build but after watching some videos on youtube about people building the exact same printer kit I feel a lot more confident. If the Prusa build goes well I might try the Kossel next.

So  I guess it's time for an update. I got the kit in Friday and unpacked it. Checked all the parts over for damage and everything looked fine. The general packaging was OK. So I began building it. Note it does not come with instructions. You will need to download those from the link on the Ebay auction page.

With that said, the frame went together pretty good. Seems some parts changed and was not updated in the manual. Things like the bearings say flanged but they are flat. They still work. Built the head a gantry, cutting carbon fiber tube is an itchy process. I would advise you to cut them slightly long by about a mm. You can then sand it down to the exact size.

You can always take away, but you can never add more.

Got the rails installed and mounted the gantry. Starting working on electronics like endstops and this is where a problem arose. The screws they supply for mounting stuff to the T slots with T nuts are 8mm. The switches are mounted to clear acrylic pieces that are rather thick. The screws are too short and let them know about it so hopefully they will amend the kits. I had 10mm screws I bought at Home Depot for another project and they where perfect. You will need about 20 of them.

The next issue was the extruder motor mount. Again with acrylic you have to remove to of the back screws on the motor and replaced them the two 45mm screws from the kit to accommodate the thickness of the acrylic.  Well my two screws seemed to have escaped from my kit. Luckily again I had screws from a previous build I could use.

So now I am doing the wring and will let you guys know more once I get ready to power it up and load the firmware and calibrate it.

I got my prusa i3 kit yesterday and got the frame put together and some of the x carriage, up until I realized that I was missing a m3 x 18mm screw. I am no expert machinist and this is the first 3d printer kit i'll be putting together, and so far it's been fairly easy and fun. They have a google drive with some videos and PDF files that show you how to put it together. Those along with a youtube video someone posted about building this same kit are really all you need to get a grasp on which pieces go where.

Going to the hardware store tonight to grab some screws and start building again.

Also, after reading up on the reprap forum which has a thread about this exact kit(http://forums.reprap.org/read.php?4,405576), I found out that you HAVE TO HOME all the axis first thing, every time. Otherwise I could get the axis to move in one direction but not the other. Also, and I'm sure all of you know this already, but you have to use a length of wire to extend the wires from the fan so that they'll reach the ramps board. Well, and I'm sure some of you can guess, I did this and since I didn't have any electrical tape i thought, "Hey, just move the wires out of the way and I'm sure they'll never touch." Well they did touch and shorted the fan out, which I didn't notice until my extruder jammed from being too hot. Got it all fixed and cleaned out but just a heads up every one, especially if you're a beginner like me, take your time and do it right!

Lots of upgrades for the 2020 already. Have fun!

Yes a few extra things purchased three of the aluminum bearing holders for the y axis that mount under the bed . I will probably put a piece of insulation under the heat bed. I purchased the optional 2004 display /sd card holder. Also a extruder heat since and the needed ceramic pot adjusting tool. I will take a look at the link. I love the support and encouragement of the folks from this forum.

nice work, Tin. We need to see some pics of it now.

FWIW, we have had ours for nearly a year (hardly use it) - did some upgrades recently and I am right back at the beginning again with futzing with the endstop settings...
It is actually on hold right now while I get the #2 SD4 sorted out with the board change...i hate doing wiring... ugh.
