Convert HH:mm to decimal hours in Excel - Thu, 08/13/2026 - 17:16

This is one of those things that should be obvious and findable anywhere right? But I had to look at five different search results! WTF!? Here is the formula:

=((LEFT(G5, SEARCH(":", G5)-1)*60)+RIGHT(G5, SEARCH(":", G5)-1))/60

Obvs change G5 to the correctly referenced cell.

Arknights: Endfield (on Linux) - Sat, 08/01/2026 - 08:10

I was recently prowling around looking for amusement and ran into Arknights: Endfield via a Let's Game it Out video, and I was sufficiently impressed by it that I felt compelled to write a little thing about it about how to get it running, and what its strengths and weaknesses are.

Celebrating the ten dollar microscope - Wed, 05/20/2026 - 19:51

I'm gonna start by admitting that the title is hyperbole, because I paid $11.63 and the price is now $15.74, but if you are trying to get a better view of stuff I can heartily recommend buying a

Fixing No Trigger on Probe After Full Movement error on FlashForge Adventurer 5M - Fri, 04/10/2026 - 06:25

Installing ZMOD revealed a problem with my FlashForge Adventurer 5M which was either caused at the factory, during shipment (but the box is clean and shows no signs of mishandling) or my printer was a return that wasn't checked over before it was sent out again. This caused me to be unable to level the bed until I fixed it. The problem revealed itself as a "No Trigger on Probe After Full Movement" error during bed leveling.

Resuming a print failed due to Timer too Close with Forge-X - Thu, 04/09/2026 - 13:45

I want to pick up where a failed print left off on my Adventurer 5M, but I'm running into the dreaded Timer Too Close (AKA "TTC") error from Klipper, which I know from errors shown on the Fluidd (web) interface instead of just having the system stop printing with no feedback like you get with the stock screen, because I am running the Forge-X mod.

Don't buy the FF AD5M... and not mod it - Wed, 04/01/2026 - 14:29

My printer is a FlashForge Adventurer 5M. I got it for about $211 shipped, which is the only reason I bought this unit really. They seem to be hovering around $249 right now. In most ways I am very happy with it, but I ran into an irritating problem today.

3d Printer Calibration, especially for Klipper printers - Tue, 03/31/2026 - 09:01

I've been looking for a good source on 3d printer calibration, one better than the Orcaslicer page on the subject anyway, and I finally found a great video in straightforward English explaining a useful, working, proven process. Naturally, it was made by a German. Once again, if you'd rather have a video, go watch the video.

Stuff I've Learned about 3d Printing, v0.1a - Wed, 03/25/2026 - 18:57

I have been 3d printing for a very short time, but I've already learned some stuff I wish I'd known earlier, and I'm going to write about it here now - both to benefit someone else who's just starting, and because I think it will be interesting to look back later and see how much I was or wasn't on the mark.

Textual guide to Fine Tuning 3D Printer Z-Offset on AD5M with Forge-X - Sat, 03/14/2026 - 11:02

I printed mostly successfully with a goofy Z-offset for too long (not that long) but finally found the resource which would tell me how to go about fixing it. I prefer a simple written instruction, but ironically the answer was a video by Ricky Impey. If you would rather watch a video, just stop now and go watch it. If you would like the entire process explained to you in text from start to stop [by a human] instead, read on.
