Favorite Prints, Printing PETG Fast, Print Dimensional Accuracy and MORE!!!

This Episodes Questions:

I got into the hobby in the last year or so, and have been looking at lots of different printers for my second machine. I'm fascinated by the design of them. I have an older, second-hand, FlashForge educational model the "Inventor", and I rarely have to re-level my bed once it's dialed in.
Why does the larger Voron design use a flying gantry with 4 stepper motors, instead of a fixed gantry and a moving build plate for the z axis? It seems like it would be so wobbly and it requires mesh bed leveling. Also, why are PEI build plates so popular when a Glass plate is so much flatter, more durable, and has better thermal mass?

Hey Guy and guys,
I love my Ender 3 v3 and I've printed a ton of PLA with it. However, the stock profile in Creality Print for PETG prints quite slowly in comparison, around 50 mm/sec. How do I go about printing PETG faster? What settings should I look into adjusting so I can bump the speed and still get decent prints? Thanks!

Hi Guy(s),

Thanks for the discussion about FreeCAD. Since I asked my original question, there has been some notable development in the FreeCAD project that might entice you or some listeners to check it out. And just to be clear, I'm not involved in the development of FreeCAD or Ondsel, I'm just enthusiastic about its progress and think it could be of use to a lot of people.
In the latest development builds of FreeCAD (available on their GitHub), they have made major improvements in the parametric behavior. Models are more resilient when making changes and references are less likely to break. FreeCAD is still not as usable as something like Onshape, but at the current rate of development, I think it is becoming serious competition.
I guess this is supposed to be a question, so how about this: What are your go to resources for learning a new program/software? Do you have any specific websites or YouTube channels you recommend for learning your CAD program of choice? Thanks,
Austin

Hey guys,
I’ve been developing an adjustable projection jig for the most popular honing guides (Guy can explain), but the parts aren’t coming out square. I have a Bambu P1S, and I’ve tried different orientations for the parts (except diagonally), and different materials and print speeds, but the parts are consistently out of square, which renders the jig useless. I’ve had the issue since the printer was first set up.
How do you recommend I fix the problem? Thanks!
