What's the better choice?
Yes, it's pretty easy to insert new commands into the file created by the slicer, it's just a big text file and all the g-codes are well documented.I am not a programmer, as my head doesn't like doing really linear thinking. But, it is possible to master the g-code made by the slicing program to change things like heat, layer thickness and speed, at different levels of the print. I have NOT learned to do this yet. Yet!
There are more expensive ways to get the first layer of melted plastic to stick to the build plate, but the first home 3D printers were build by tinkerers, so the idea of "what do I have around the house that might work" is how people came up with stuff like painters tape, hairspray, glue stick, etc.But amid the complicated tech talk about this and that, I am somehow encouraged by the 'down and dirty' solutions like blue tape, glue stick and hairspray. It ain't pretty but it works, right? No Robot or rogue A.I. trying for that Revolution deal is going to figure THAT formula out!
I don't think it's a layer sticking to each other issue since there are plenty stuck together below the problem.These are the ABS Bussard Collectors (one with a flashlight in it), you can see how the lack of temp caused the upper layers to not adhere and glob up.
The travel speed should actually be slower when printing small areas because acceleration doesn't have a chance to kick in. Unless your slicer is weird and is increasing movement speed in small areas.MartyS - I just thought that since the print was getting narrower there, it meant that the head was moving too fast and the volume at that height was cool enough to stop the layers from adhering to each other. When I slowed it down and raised the head temp, I thought it had solved the issue. The Witbox stepper motor does have a fan attached directly to it. I will do a test print to see if the fan has stopped working. Also, I usually have the fan run at 10% speed during the first 30 layers (3mm) to let the laid down material cool off more slowly, then it goes to 100%.
Not if it hasn't been overheated too much, too much prolonged heat will weaken the magnets inside the motor and then it would have to be replaced.If the extruder stepper motor is heating up, could this be an indication that it should be replaced?
Did you download the botany bay or make it yourself? I'd love to print one out to put next to my 1:350 big E.Today I printed out a 1:350 SS Botany Bay to display next to my Big E. I printed it at my printer's highest resolution so I will likely be able to fill most of the layer gaps with Rustoleum Primer 2 in 1 Filler & Sandable.
