Folger Tech Kossel Delta 2020 Full 3D Printer Kit w/Auto-Level

Hello everyone! I've finally put my kit back together with all the final modifications I wanted to do for it.
[attachment 47600 IMG_7314.jpg]
I have cut 5mm thick acrylic to fit on the top and right underneath the heatbed. They do make the whole construction more rigid. You can see that I reprinted the frames, because they cracked.
Some of you may know that I didn't use the original heatbed. I have a silicon heatbed that heats up a lot faster and even with fiberglass insulation sandwiched between the heatbed and the acrylic, it gets warm underneath it, so it makes sense to move the RAMPS on top. Of course, you have to extend the motor wirings. I still have to tidy up the wire a little bit more.

I had some leftover high density foams which I used to dampen the rods. They make the whole unit so much quieter.

I downloaded FSR mounts from thingiverse and modified it so it fits and holds the bed down securely. I am also using 16-teeth pulleys now and from the looks of it, it's working pretty good so far.

I've also printed better carriages, because I had to glue the ones that came with the kit, because they were broken, just to make it work the first time.

When I bought the kit, I wasn't really expecting something that I would put together with ease and with good quality parts. For the price that I paid for, I am content I got the linear rails that could be pretty expensive if you buy them somewhere else and the aluminum extrusions are of good quality. So a fair warning to someone who is interested, this is not a kit to buy if you just wanna build it once and never have to modify anything.

I like it! Very nice work. Yes, the kit is definitely not for everyone. It's a lot more fun ppl who have extra time and like to tinker. I make a few mods myself, not as extensive, but will post when I tighty up the wires. Your print looks awesome, PLA? Acrylic bed, did you cut that by hand or CNC it? Like that idea and will definitely try it on mine. Also, does your three axis motor get pretty warm? After 30min, mine's get pretty warm and I am concerned.

Hello everyone,

I got my Folger Teck Kossel kit and put it togetther, Flashed the FW and Installed Repetier Host everything seems to be working right I can manually move the
Print Head/ Extruder around and when I hit home it goes up hits the endstops and parks and waits for the next comand. The Filament feeds the Extruder heats
up and filament extrudes. But if I load a file like the 10mm Calibration Cube file it shows up but then when I hit print it goes from Idle to Print Process Complete.
This happens as soon as I click Print. I am new to 3D printers so any help would be greatly apprecited but remember I am new so please go easy on the
technical lingo. Looking forward to printing on this printer.

Thanks in advance

I am patiently waiting for my Kossel to ship. May I ask everyone how long was build time (from start to actual printing)? Sounds like everyone needs to spend a decent amount of time working through the unique 'kinks'.

Thank You!!!!

I tried that and it started the print and printed a beautiful little bird's nest. I don't have it set to go all the way down to the hot bed yet I still have to get that part figured out. But just to actually see it do something was exciting.
Again unnokeng Thank you so much for your help....

Congrats! Care to share your configuration file for your firmware set up?

I'm close, but my printhead is going in the opposite X direction from the Repetier Host display. Tried inverting the X in the config, but inverted the X tower direction-- not the head direction. Had to reroute the hot end heater to D9 since D10 connectors broke and then just soldered the fan to D10. Finally got it all functioning right, except for the X direction and actual flow rate for the extruder feed.

I also used 5mm plywood for mount my hot bed after hearing stories about the acrylic mount, and to mount my circuit boards more securely. I used silicone spacers to elevate the hot bed a bit and add some cushioning.

Learning tons. Was hoping to have a test print cube by now, but also learning patience.

you just want a copy of the Arduiono Sketch?

Have the kinks been worked out with this kit yet?

Considering buying it for my first printer. I'm not above modification or tinkering, but I'd like to know the kit comes with everything needed. It seems there's a problem with the teeth count on the gears, did they reduce it to 20 or is this still an issue?

Does the firmware it comes with still need tinkering?

When i click on 1 mm down at the z-axis, it is moving 1.5 cm, so 150 times more? this is at 44.444 steps pr. mm.

Have i missed something ? (the motors are also a bit hot)

Hi folks,
Same issue with Kossel K800 Delta printer. Ether X or Y axes are inverted so any print come up mirrored. This is not big deal as perfect print could be generated by manually inverting every object in Repetier before slicing.
I have also tried different things to fix this issue.
Issue first came up when I switched to Repetier firmware, I had no issue with Marlin firmware. But I find Repetier firmware much better for fine tuning and calibrating for perfect prints.
I have tried to invert one of the axes connector, to invert axes in firmware, to invert middle wires in connector, in all of those cases axes are inverted but this also apply to Z which is not what I want.

If noone have found solution for this issue, then next stop is to modify repetier firmware source code.

Hey, i have a big problem. When i print in "dry mode" it works fine. But when i click the normal "print" it dosn't.
It goes to home but just keeps heating.

* The tempeture viewer freezes
* The Extruder is heading, and i know it is at 200
* I have reinstalled repeater again.

Does some one have a clue what could be wrong?

Try posting this in the Repetier SubForum I am sure the Author of the software will see it and he will answer

Iceman62,
Oh. I see it is Marlin firmware. I've been using Repetier. Going to try a few more things with Repetier, first.
