My Tantillus was built out of 1/4" MDF so I had to modify some of the plastic pieces to for the thicker material. You can find them on github.by lajos - Tantillus
Another thing you might want to do is make sure you are printing at high enough temperature. I was having a similar issues, retracts would kill the filament. Sublime suggested to increase the hotend temperature, and it solved my filament stripping issues. Check out the Tantillus calculator. (The link is from Sublime's signature.)by lajos - Tantillus
The mega2560 is not (pin) compatible with the atmega644p. You can use an atmega1284p. Although I doubt the atmega is your problem. They are tough little chips. You should do some more troubleshooting before you pull the soldering iron out. Can you program it through the ISP?by lajos - General
You can program the atmega through the ISP port that's on the Sanguino. You need a programmer that can handle 128K atmega. Some of the cheapo programmers can't do that, but if you have access to for example an AVR Dragon, you should have no problem. However you need the ftdi chip to later communicate with the board. Without it you won't be able to talk to it with pronterface or repetier host. Yby lajos - General
Sounds great, except for the "cloud". Why not do the processing locally? What happens if something happens to the "cloud"? It looks like the images you posted are 3d renders. Do you have any pictures of the prototype?by lajos - General
There is probably no "E" command. It should be something like this: G92 E0 G1 F500 E2 G92 E0 This resets E, purges 2mm, then resets E again. I tried retracting at the end of the print, but it didn't really work. The filament would still ooze, and you just deplete the hotend even more.by lajos - General

The stepper drivers can overheat. Try lowering the motor current. Adding a heatsink would also help.by lajos - General
It's looking very nice! For drilling the holes I made a guide from MDF. Look at this post. It's basically a piece of MDF with an 8mm hole drilled length wise, then cut in half with a saw. The small hole prevents the drill from slipping. I still think you should be able to do this with the HSS drill bit and cutting fluid on a drill press. Maybe you got some super hard rods or your drill bits arby lajos - Tantillus

@vegasloki: So then why can't ohioplastics post his advertisements? If you look back up a bit, you can see Sanjay plugging his hot end on this thread also, on top of being allowed to advertise in general.

@nophead: To ohioplastics's point there are at least two other vendors who advertised their hotend in this thread (even if he's saying it in a semi-ridiculous way). There are also other threads in the general forum that are adverts, for example the E3D hotend released one (and that one goes overboard with the animating GIF in the subject).

Are you sure the issue is with the hotend? I have the same hotend you do (from hotends.com), it doesn't jam and prints beautifully. Your j-head should not jam, especially with ABS. If you are getting jams so bad that the filament is chewed up, you are probably just printing at a very low temperature. Make sure that you have the correct thermistor setting in your firmware. If still jamming, raisby lajos - General
Use some cutting fluid to cool the bit and the rod. I drilled my hardened rods using a regular hss drill bit at low speed. High speed might just create more heat.by lajos - Tantillus
You can get SDRAMPS support in Marlin under 64k, so it should fit on the brainwave. You only need the data pins from the ISP and power to run the sdramps, all of which seem available on brainwave. If this is a bigger project involving multiple printers, I would not use that motherboard. It's advertised as simple and cheap, but cheap it is not. You can get a Sanguino kit with 4 stepper drivers beby lajos - General
The boards are not designed to run a specific firmware, like marlin only. You can run a bunch of different firmware on the same board, in fact all these boards are usually just arduino clones with some 3d printing specific ports built in. You can use marlin, teacup, repetier, sprinter, or you can just upload an arduino sketch and blink some leds. You are asking the board manufacturers to provideby lajos - General

There's not enough memory to "download" the gcode. The firmware has a buffer, but it's only 50-100 lines. Communication is serial over USB through an FTDI chip. The communication is pretty slow and unreliable, so most people print from an SD card that the firmware can read directly.

I assume your stepper drivers are good, you mentioned they worked at some point, it would be highly unlikely they all burned out at the same time. Since you have temperature reading and host communication, your microcontroller should also be fine. Is it possible that while you were working on the firmware you accidentally modified the pin assignments? Can you try marlin just to see if it works?by lajos - Sanguino(lolu)
Does the hotend heater and thermistor work correctly? Have you tried a different firmware or at least re-uploading the one you use currently?by lajos - Sanguino(lolu)
Have you measured the voltage on the atmega pin that's connected to D10? If the pin was shorted and you drove current through it, you most likely burned that port out. If that's the case, you would need to replace the microcontroller.by lajos - General
Thanks for the tips about using support in KS. I started with openscad because I was curious why others in the 3d printing community use it. A programmers' solid modeller sounded great, but I'm not sure that I fell in love. It has a long way to go: - the language is declarative. Fine with me, but it takes away a great deal of flexibility.

That's a pretty high bar I've never had any issues with my j-head nor my home made ptfe bar/aluminum nozzle hotend (that was used on my cnc machine).

Thanks for the info on the support. I thought you mentioned that you printed the warrior princess hollow, so I just assumed that the support would then take the place of the infill. I never even thought about looking at the model, because it was generated from openscad and figured it would be a nice mesh. But you are correct, it's not a nice mesh. I guess the lesson learned today was to never aby lajos - Tantillus
Two LM8UUs are too long for the carriage. You would lose 7 millimeters on X and Y axis.by lajos - Tantillus
Encouraged by Sublime's warrior princess print, I wanted to test slicing an object hollow with support in kisslicer. My kids lost their yoyo, so I downloaded this from thingiverse. When I slice it, after the solid layer prints on the bottom, I get an insane amount of destrings for the inside support. I actually stopped printing because I was afraid the extruder would just chew the filament up.by lajos - Tantillus
It's looking really nice! I've started working on a bigger tantillus in openscad, and it's a lot of work to even get simple parts made. Let alone create an assembly. I mainly started the project to learn openscad, but I've had second thoughts many times, a package like solidworks/inventor would've been a magnitude more productive.
