I've been printing the same large flat model (230mm long) which is basically a box on my P1S for a long time and more recently on my U1.  If I print it at 70-75C first layer and 5° less for subsequent layers the corners warp a bit too much for my liking.  I use a BIQU glacier plate because I like the texture and how it releases.

I get a much better result with 85C for ALL layers printed with my IKEA top on and the door shut.

Because I use PLA for support in some areas, I am conscious of keeping the enclosure temp down to below 40C to avoid heat creep in that tool head.  With this set up it stays at about 37C without clogging the dedicated PLA nozzle.  I'd be cautious to try 90C.

You can see from the attached photos how much 10° more bed temperature throughout the print helps.

The nozzle temp was 230C in both cases and the results are similar across several brands of PETG. I run the part fan at a constant 30% with auxiliary fan off and attach a wide outer brim. My plates are always cleaned.

The print finish is improved as well. It's simple, for large flat prints, PETG likes heat from start to finish.

I hope this helps someone.

I just got this error today when trying to print a simple little test model that I had cut with 3 small hexagonal connectors to test how it would glue up. The error says "x-axis movement exceeded travel limit." Here's a link to the wiki help page regarding the error: x axis anomaly exceeds travel limit

Since the model is small, only scenario 3 in the wiki link seems to apply.  It recommends  changing the first layer height or moving the prime tower.  Changing the first layer height didn’t help and there is no prime tower in this model.  The wiki also suggests enabling the travel option in the slicer display. When I do that, I do see a skinny blue travel line beyond the normal travel area - could that be the problem? What causes that, and how do I fix it?

As a control, I created and printed a small rectangle on a different plate and I did not get the error. I've recently printed other models without the error as well, so it must just be something that either the slicer or machine does not like with this simple cut model.  Can cut model connectors confuse the slicer?   Ideas?  See photos.

I've got a project in mind to put a nice line drawing on a box. So, I've been teaching myself how to do it by adding a modifier with an SVG file. I am astonished how easy it is to add the file to a surface and either engrave, emboss or embed a design. The attached photo is a test PLA piece 120 x 80 x 5 mm using two colors.

The white part is embedded only .5 mm, but I think it came out great. It's printed using a standard 0.20 profile, taking 59 minutes to complete. I checked how long it would take on my p1s and it looks like it would have been 1 hour and 15 minutes, so not a huge difference because there were only three or four color swaps in total. It's nice to know how to do this. See this 5 minute video that I have made on this topic: How to add SVG file to object in slicer

I decided to put a 8x10 clear acrylic view panel on the side of my Ikea top cover so I can see what is going on inside.
