Long time lurker and finally started my journey into creating the V4.
I’m printing the 3D printed parts myself, due to shipping cost and import charges. But by doing so I have run into probably a common problem- part warping.
While the small parts print ok, the YZ plate has caused trouble. I probably can reprint the parts and better dial in the first layer, use hairspray, etc. But before doing so, I was wondering, is there any amount of warpage that is acceptable?
It’s a home built core XY type printer, glass bed, e3d v6 with 0.4 nozzle, bl touch probe, using skr 1.4 board. Build volume around 200x200x200, enclosed printer.
Currently printing bed at 60c, hotend 200c, with Creality Hyper PLA ( Hyper 1.75mm PLA 3D Printing Filament 1kg )
Previously I tried blue painters tape on the bed, but had the warped parts.
Currently I’m printing the core with same temps, but instead of the painters tape, I have used hairspray, standing at 35% done, looking good so far, but will see how it ends.
I probably would recommend re-printing the parts if you’re able to. They would probably work if you didn’t have a choice but you might have some problems
Currently the core stands at 75% and it is flat and firmly attached to the build plate, if it turns out OK, I will reprint the parts with the hairspray method (I just hate that it smells up the apartment). I don’t have any other parts yet, so I can’t quite yet test fit anything to check if it would work as is.
The PEI sheet is something I would like to entertain, but I don’t think I can source it locally right now and the wait time from Aliexpress is longer than my patience.
Nathan, I’m not sure what you mean by that, to be fair, English is not my first language, so I might be out of context saying this, but I printed them with the largest flat side to the build plate, as it opened in Cura like that, but as far as I can tell, it seems the correct logical orientation. Let me know if you think that I need to print it vertically.
And here is the core right now, the printer is brutal, but sourced from what was available at the time
They should be printed standing upright, not laying down. They should also open in the correct orientation, but i don’t use cura (orca for the win) so i dint know if it messed with the correct layout.
Thanks all for all the support, the core turned out quite well, I would even dare to say that it hasn’t warped at all and it gives me confidence to try and reprint the large pieces.
On a side note, ordered a lot of parts from Aliexpress for the build and will start the build process soon-ish, probably a build thread will be in order. There are still few random bits to collect, like the 32mm piping and XZ plates. I already reached out to few vendors, but none seems interested in such a small order. Managed to get some company to sell me 400x200x8 mm aluminum piece, so probably I will hand cut the first edition (will lasercut a plywood template and use it as a guide) and later, hopefully, I will be able use the leftover piece to CNC the parts.
Dimensions wise it looks like the piece is big enough for two sets
Depending on how thick material your laser can cut you may get away with laser cut plates to bootstrap the machine to cutting its own end plates rather than trying to hand cut the plates with a laser’d template. I chewed through a lot of ply at some fairly serious speed and DOC with endplates of ~5mm ply. Worked in a pinch, definitely got worse over time - initially the machine failed to lift Z without a little assistance only at the very top of travel, it now does so more frequently and lower down. They might have been up to machining the plates in alu with the machine when they were still fresh off the laser
Needless to say, use extreme caution if you attempt - I’m just a big fan of bootstrapping
