Topic: Mini kossel w/ J-head, RAMPS 1.4, heated bed for sale. Needs PSU.

Up for sale is my mini kossel.  It is a well built printer that has very little run time on it. I sourced all parts myself.

Imgur Album:  http://imgur.com/a/7ffRU

Details:

  • 1515 misumi aluminum extrusions, 240mm and 600mm (standard sizes), so approximate print area is 170mm diameter by 220 mm height.

  • All printed parts printed in ABS by me on my solidoodle out of black or blue ABS (except extruder gear, which is nylon)

  • Hot end is a brand new J-head with 0.40 mm nozzle that has literally never had plastic thru it.  Previous use of this printer had a different hot end.  Everything is wired with JST plugs and I can throw in a few extras.  It has an auxillary line already wired to the print head incase you want to install a nozzle fan or an LED or anything.

  • Motherboard is a RAMPS 1.4 with DRV8825 drivers for 1/32 microstepping.  I will include a printed case with 60mm fan (not pictured).  All wires are labeled with a label maker at the board.

  • GT2 belts, 20 tooth pulleys, NEMA17 1.8 degree motors

  • Heated bed is a very nice silicone pad, 240 watts, not a cheap resistor based board like other kits.  It has an aluminum spreader pad, heater is held on my its own sticky pad and then insulated with cardboard held in place with kapton.  Then I counter sunk the attachment screws and installed the bed on springs to avoid damage if you crash the head.  It also has a custom cut glass bed over kapton.  Really a very nice heated bed!

  • Extruder is a geared Wade extruder, so it has a lot more torque than other kits that only use a drive gear direct on the motor.  The gear is nylon, so it runs much quieter than other ABS of PLA gears.  All springs and bearings are in excellent condition and came from McMaster, not a cheap Chinese supplier.  There is also a custom filament roll holder on the top so it feeds directly into the extruder.

  • Top and bottom have thin woods panels to keep everything tidy.

  • Also includes 3x FSR sensors.  I never really liked these so I took them off, but maybe you will have better luck.  You would have to go back to an unheated bed (not recommended) or use one of the groove mount kits to mount these in the print head.  This is really a mod for a serious tinkerer.  Good luck.

  • Everything connects fine and I have confirmed that all heaters and thermistors work.

  • The probe has not been installed since I never got around to it.  I will include the endstop but I don't have the various springs, etc. 

  • NEEDS: does not include a PSU.  You want the "12v 30a Dc Universal Regulated Switching Power Supply 360w for CCTV, Radio, Computer Project" for $23 on amazon.  That is the one shown in the pictures but it has been pulled for another project.  There are plenty of guides online for how to do this, if you are the type of person who is ready to own a reprap like this, then this should not be a challenge.

  • NEEDS: full calibration.  Again, plenty of guides online.  The last time I had this running it had a different hot end, so switching that out changes everything and it needs a full re-calibration.  I don't really have the time to do this.

  • NOTE: the pictures shown are from last week, since then I have countersunk the bed screws and put on glass that covers the entire surface.  Note that the shown PSU is also not included.  More pictures on request to your email.

Asking price: $650, OBO.  Don't bother low balling me, its a good machine and I'm not desperate to get rid of it.  That is less than a maker geeks kit and you are getting a lot higher quality parts than their cheap hot end and weak bed heaters.  If I get more interest, highest offer gets it.  If it doesn't sell here in one week, I'm installing a new PSU and putting it on ebay starting at $750 do here is a chance to get it cheaper.  Payment will be paypal bank transfer (CC if buyer pays the fee) or bitcoin.  Seller references available.

This is a good printer, I just lost interest in it and I have other builds going on now that I would rather focus on.  Asking price is $650 plus actual shipping.    Shipping will be fairly expensive, I'm thinking I will ask for $60 shipping (USA) but I will refund any difference.  It will be shipped via UPS ground with full insurance and a ton of bubble wrap.  I could disassemble the towers and lay it flat if you want to save a couple dollars but its probably not worth it.  International buyers will pay actual costs to ship it DHL with full insurance, which will not be cheap at all.  I've had a bad experience shipping postal service international so that will not be offered.

As a bonus, if you want any additional printed parts to customize it, I will print and include them for free (within reason).  Questions welcome, thanks for looking.

It's up on eBay now.  I would like to see this gone so I can start on my next project.

Bump.  Price reduced for the final 24 hours of the auction and now offering free shipping since I want it gone.  Will not be further reduced.

I think you may want to reconsider the price. You can get a full kit like this one with everything integrated into the unit and with the PSU new for $399. That's $425 with shipping.  So whats the incentive to buy used incomplete for $100 more and have to buy the PSU as well for $40? I realize you may have time and effort put into it but all 3d printers have a horrible depreciation rate once used.

Printing since 2009 and still love it!
Anycubic 4MAX best $225 ever invested.
Voxelabs Proxima SLA. 6 inch 2k Mono LCD.
Anycubic Predator, massive Delta machine. 450 x 370 print envelope.

Really? Where? Does it come with a genuine J-head? DRV8825 drivers? A 240 watt heated bed? Quality bearings?

The way I see it:

J-head: $60
RAMPS + DRV8825s: $80
4x Steppers: $40
Heated bed: $20
Printed Parts: $60
Extrusions: $50
Bearings/hardware: $40

Time spent assembling: $100

Its worth $450. He'll get about $420 after eBay fees and shipping. His price is fair.

The Foldgers kit I got and have nearly completed was 399 and includes an E3D clone hotend. But I was simply making an observation that he may find it hard to sell at that price. I had 3Dstuffmaker with the exact same hot end and had to settle for $275 and eat shipping in order to sell it when I paid $800 for it. They just have no resell value on ebay now.

That E3D clone is garbage.
FolgerTech has A4988s, which are inferior to the DRV8825s in this printer.
FolgerTech has a weak heated bed.
This already comes assembled, saving me 10+ hours.
The only part of a 3D printer that really matters in terms of used is the hotend, and this hotend is brand new. Alu extrusions don't "wear out". Your 3Dstuffmaker didn't sell well because it is outdated and unpopular, not because it was used.
