I can not get gcode.ws to make an estimate for the benchy I just sliced :( :sad:

Cura says about an hour, so I bet it'll be like 1:30 or 2:00

There is http://www.gcodeanalyser.com/ as well.

FYI for a recap on materials I have sort of narrowed down to two sources.

https://seacans.com for PLA but due to shipping Amazon might be cheaper for you in Alberta.. It prints well and for me gets delivered in 2-3 business days.

https://www.amazon.ca/MG-Chemicals-Printer-Filament-IMPROVED/dp/B018MG4PF4/ MG Chemicals for PETG.. but you have to use a price tracker to watch for sales, it goes crazy cheap at times and over all is WAY cheaper than any other place I have found for PETG https://ca.camelcamelcamel.com/MG-Chemicals-Printer-Filament-IMPROVED/product/B018MG4PF4

Dialing in your temps and settings for a material is important to get the most consistent quality so settling down on specific brands helps a bit.

Seacans  did a run down of Canadian filament suppliers (note some are out of Alberta)

Tried that as well, but it gets me some insane length of time. Not sure what values I need to enter for all the settings there. I tried just matching cura settings to the form, but it didn't seem to help.

I ordered some PETG from Spool3d.ca for reasons I can't quite recall atm. Haven't used it yet. but will soon. :D

I leave it at the defaults as the printer settings them selves only act to limit things if they go over an extreme.. The gcode it self dictates the moves and speed.

Benchy is a good test to do over all performance testing of find detail.

If you just want to dial in speed and dimension accuracy the xyz cube can be printed very quickly https://www.thingiverse.com/thing:1278865

Check these numbers out:

Ya, there is something VERY wrong in your slicer settings somewhere.

Tom

I'll try reimporting from the cat model and see if that helps.

Printed quite well for almost no printer calibration (minor bed levelling with a piece of printer paper), and some settings I had setup for the old V1 printer.

Took 1:31. About what I figured based on what I remembered from cura's estimates with the V1.

Not bad, looks like you have zits/lumps at the layer changes which indicates that retraction or extrusion settings are not quite dialed in..

I would hunt around for a more current set of printer / extruder settings for your printer and also maybe reset everything in cura just to be sure you didn't introduce anything previously.

The fact the previewers could not generate a preview and proper estimate makes me think there is an invalid value somewhere... The printer firmware will just ignore such an error with its firmware limit values but the gcode still has something odd in it.

Yeah, I've created a new printer in cura, and set up the defaults for the main profiles. printing the calibration cube now with fine 0.1mm quality. I might do another benchy at draft again with these settings to see what's up.

I sliced a new benchy with the new settings, and it worked fine. though its guessing 2h instead of the previous 1:30 it took. so we'll see what settings changed.

I think I posted previously that AS IS with no tweaking those estimators tend to be only accurate between +/- 20-30min for me.. Which on a 20hr print is good enough but ya on shorter ones is a wide margin of error.

I think in this case, the settings were just that weird. That benchy is just about to finish up, and its been about 2 hours so far.

What I want to do now is get a bunch of different colours and types of filament to make alphabet and number cubes out of...

Took 1:47 in total. Not too bad.
