I think you are correct. My efforts do not insulate well enough to heat the interior. I put "mouse ears" on my print and it stays mostly flat, but still curls. I get cracks in the main body too AND I have to chisel the part off of the BuildTak, Ahh!!! I may have to dedicate a machine to JUST do ABS and put it in an oven to temperature control it.

Quote691175002 I print almost exclusively ABS. With the brands I've been using the build chamber must be >45c and <50c. I have a vent at the top of my enclosure that is partially blocked by a piece of cardboard. I leave a multimeter thermocouple in the chamber and open/close the vent to adjust temperature. In my experience there is really no way to reliably print ABS if the chamber is &by dlc60 - Reprappers
Quotedc42 What temperature does the chamber reach? Perhaps it's still too low to prevent warping effectively. The last temperature I took at the end of the print was 31C. I'll have to attach a print of the piece. It looks pretty well stuck to the bed, with a little warping, but the big problem is that about every 30 layers or so the print cracked, big time. ☹️ If the part warps, the model doesnby dlc60 - Reprappers
In the ongoing saga of getting ABS to print I have found something that works, mostly well. I do not believe that perfection is possible. I hate this stuff... But, I have fully enclosed my delta printer (see image). I tried rotating the part so that the infill was different. I dropped the hotend temperature 5 degrees (250 to 245) and raised the bed temperature to 110 C. AND added BuildTak toby dlc60 - Reprappers
Quotenumber40fan Yep, that is what I meant. Changing the offsets so they aren't pulling on the effected areas as much. I am going to try this. I already completely enclose my printer and I just put a "BuildTak" surface on the bed. I will add this angle change to the process and see what happens. Thanks!, DLCby dlc60 - Reprappers
Quotejinx heres a mount with a 3mm spacing if that fails you can find a 2 mm spacer titan mount Thanks for your effort! The E3D site has a SCAD file that allows you to gen the spacer you require. So I made a 3mm one that now allows the stepper spur gear to sit low enough to be flush with the extruder gear. I rebuild my Titan with a longer bolt that bottoms out in the extruder shaft hole, withby dlc60 - Reprappers
Quotenumber40fan I just looked at your list of tried "fixes", but one that I didn't see was either changing the orientation of the part on the build plate or changing your layer directions. Have you tried any of those? I have not. I assume you mean the infill angle offsets? I use Simplify3D as my slicer/printer. Interesting idea! I have not tried either of these, it simply didn't occur to meby dlc60 - Reprappers
Quotejinx "but you can't put a heat sink on the stepper like I could on the Thing that I built, which is a drag" reduce the current to the driver, I've ran 3 T clones for 18 hrs a day and the stepper just dont get hot enough to warrant a heatsink on the stepper. as for the bolt coming loose you sure you put it in the right hole, first time ever read about one coming loose.

I may not yet have perfected ABS, but what I have learned has me now printing perfect PLA without heating the plate at all. I print right on glass using Elmers Extra school glue stick. For tricky ones I print at 60C on Kapton tape with glue stick and need to chisel the parts off. Next is PETg when I get ABS down. Thanks, DLCby dlc60 - Reprappers
Quotenumber40fan Do you live in the states? I have some injection molded corners from an HE3D delta that I don't need any more. There are 9 pieces in total. I am building a new flavor designed by some guys at Microchip whose design does some different stuff. For one, they put the psu under the deck and electronics outside. That boosts the deck up a bit so I will need these corners. Thanks forby dlc60 - Reprappers
Quotenumber40fan Sometimes it is the filament that causes the issue. I have a roll of black ABS from Hatchbox that warps like heck on a long run, but the same part with other ABS filaments, does fine. Try lowering your layer height too. .2427 (yep, weird number, but proven to work with Deltas) and try again.

What do the people out there think of the E3D titan geared extruder? I got the universal kit and sketched up my own Bowden adapter, I didn't think theirs was worth $16 just to make it a Bowden.

Quotedc42 Quotedlc60 Yes, this is a delta printer, leveling the bed is half hardware and half firmware. Measuring from the tower limit switches to the bed, all are the same.

Quotecwaa I also use a 120 volt bed heater and it heats up faster than my hot end. I have an enclosure that I use in the winter, but all the rest of the time I print ABS without one. How does one control a mains powered heater? Thanks, DLCby dlc60 - Reprappers
I just got one of these when 3D Printers Bay put the base model on sale for $160. I added the heated bed and slide rails to my buy. I needed some components for a custom build delta and it was cheaper for me to buy this kit and not use half of the parts than order ala-carte parts from around the globe!

All good suggestions, but I have some questions. How do you get the beds that hot? It is all my system can do to reach 105C, and that takes half an hour at least. If you don't use a glass topper for the bed (so it is really flat, aluminum beds are always warped in slight amounts) do you apply your tape/slurry directly to the bed plate? If you use some other liner for the bed, how do you holdby dlc60 - Reprappers

I have no problems getting PLA to print on blue tape without warping - no surprise, but I am designing a custom delta and need to use something tougher than PLA for the plastic pieces, so I am working with ABS.

I just got a new E3D hot end. I had this problem and initially solved it by raising the temperature 30 degrees. The next time I had the problem I needed to replace the nozzle. The NEXT time I had the problem I solved it by reducing my print speed. These solutions were cumulative and the last solution was filament related. The filament was a little softer than the PLA+ that I was using before.by dlc60 - Reprappers
Quotenumber40fan That is exactly what I have, but people get confused if they don't know exactly what it is. Get a spoon to hold the nozzle. Sounds simple enough. thanks, DLCby dlc60 - Reprappers
Quotenumber40fan If you have a way to heat the nozzle up to high temps, you can burn out the PLA. I use a propane torch and it will vaporize the PLA and leave you with a perfectly clean nozzle. I have a MAP gas torch, that should work. Thanks, DLCby dlc60 - Reprappers
Quotewaitaki I guess you are using PLA? I make my own hot ends based on the E3D design - with some differences but.. I print mainly in ABS. PLA can cause havoc in many types of hot-end and I wouldn't be surprised if the Prometheus has its problems also -not that I would know. If I use PLA, I am very concious of the fact that it can't be left hanging around in the heater block. To this end, I getby dlc60 - Reprappers

As I wrote above, "Replacing the Arduino board solves the issue, i.e. Ramps and stepper drivers are still working perfectly" I have clocked AVRmega pins in the MHZ range, so something else has gone awry, clocking the I/O pins at any rate will not damage anything on the chip.

You probably destroyed the stepper drivers, not Arduino pins. I have blown the tops off motor driver chips by PWM'ing them at too high frequencies. If you have a Ramps board, replace the stepper drivers and I'll bet your unit will come back to life. DLCby dlc60 - Reprappers
The hot end is a constant threaded one with no gap in the threads. The hot end is one of those that have the hot end combined with the extruder and the stepper behind it all. It is for a Cartesian printer. It is about as direct as it gets. There is nothing in there to prevent the tube liner from being pulled out with the filament. DLCby dlc60 - Reprappers
I have read that the maximum layer you can put down is between 50% and 80% of the nozzle diameter. With a .4mm nozzle, at best you are limited to a max of .32mm layers. I regularly do .3mm layers with my .4mm nozzle. To guarantee that my first layer goes down and stays there I run it at 20% of my normal print speed and put that layer down at 90% of my layer height.
