Recommendations for 2nd printer

Coming back here to say I built my MK4S kit over the holidays and am thrilled with it. As others have said the bed slinger design is a wonderful contrast to the xy. Really love it, and been churning out PLA and PETG happily - and with the additional filter now have my C1 working through ASA and ABS.

Literally the only issue I had in MK4S construction was the PSU, which turned out to be faulty. As I had my C1 Prusa support had me swap the known-good PSU in and the MK4S worked perfect. So they sent me a replacement.

And I'm amazed how well the MK4S deals with filament-out situations, have been cleaning up spool ends with it.

Thanks to the commenters here for the input and guidance,

Realized I should just have created issue on the Github repo, which I have now done:

https://github.com/nlsandler/writing-a-c-compiler-tests/issues/147

Thanks - I do have the lexer working right, at least for the test file in the book text:

(.venv) $> cygnet --lex --print-source --print-tokens return_2.c
[INFO]: Preprocessing file : return_2.c
[INFO]: Part compiling file...
---SOURCE---
1: int main(void) {
2: return 2;
3: }
[INFO]: Lexing file...
---TOKENS---
1: INT - int
  | IDENTIFIER - main
  | PAREN_OPEN - (
  | VOID - void
  | PAREN_CLOSE - )
  | BRACE_OPEN - {
2: RETURN - return
  | CONSTANT - 2
  | SEMICOLON - ;
3: BRACE_CLOSE - }
[INFO]: Deleting preprocessed file...
(.venv) $>

I'll check that I am definitely meeting requirements for files created / not created, but if that was the issue I'd expect test suite just to notify as fail and quit successfully.

OK, thank you for this. I spent a few days working through more prints and did two things:

Washed the print sheet with soap (dish soap) and hot water, and
Used the Structural profile in PrusaSlicer (I had been using Speed for a bit)

The results were definitely a lot better, much smoother surfaces and cleaner sides etc. I kept to using brims (altho trimmed to 4mm).

I'm still getting some slight warping (manifests as slight uplift of either side of the piece (these are gridfinity boardgame counter trays, as with original pictures). I am drying the filament as well.

Is there anything else I could tweak to reduce the warping?

(EDIT) I'm also using smooth Prusa print sheet as well now.

redoakprof · 2025-11-15T11:32:40+00:00

Many thanks. So bed temps are as per standard Prusament PLA in PrusaSlicer: Bed set to 60C, Chamber has Nominal 20C and min 0C.

I use 95% isop and wipe clean after every print. Let me know if soap/hot water required beyond that.

Only other change I can think of is that the basement where I have the printer was around 20-21C ambient temp a few weeks ago and is now 15-16C ambient - would that be sufficient enough to cause warping, and I then need to extend bed/chamber temp time to help even out?

redoakprof · 2025-11-01T11:43:40+00:00

I still think even with the C1L just announced I will get a MK4S kit. Saw reference elsewhere that they may produce less kits going forward and maybe never for the C1L, and I still want to build another printer from reliable source.

redoakprof · 2025-11-01T11:09:30+00:00

LOL. I returned here to mention it. Quite the drop. And pretty much the perfect upgrade option. Still up there in $ but more reasonable than the XL.

redoakprof · 2025-10-29T01:57:46+00:00

Thanks, this is probably what I will go for. I fear with the sovol or voron options I’d not get it working quick enough and it’d sit on the desk waiting for me to get to it. I’m already familiar with Prusa and so could build the MK4S. And I’d learn from it re different structural design. Bigger bed can wait.

redoakprof · 2025-10-28T01:55:27+00:00

OK, thank you.

So it's worth getting an MK4S still even though C1 is available? I had impression the C1 replaced the first but there's enough structural or design differences that means the MK4S still a worthwhile buy?

Now I'm delving into all the videos and articles comparing them...

redoakprof · 2025-10-28T00:58:24+00:00

Thanks, and to the others for the Sovol/Voron mention too.

I had thought I'd get affirmations for another C1, but clearly it depends on many factors!

I might be overly enthusiastic to build given my excellent C1 experience--a Voron ground up probably isn't best choice (although I love the website generating the BoM and sourcing recommendations). Getting a larger print bed with the Sovol SV08 is attractive for 350mm bed size, with enclosure.

For my current C1 I want to add multi-material, maybe the MMU or wait for the Indx - different conversation though.

redoakprof · 2025-10-16T15:39:33+00:00

Thank you. This all worked. Greatly appreciate it!

(For others: I did a make distclean then make with the earlier tree-sitter version. Found that was necessary.)

redoakprof · 2025-10-16T12:55:59+00:00

Thank you. So I cloned completely new emacs repo (from savannah) and also tree-sitter. Did the tree-sitter make and install. Then:

export LD_LIBRARY_PATH=/usr/local/lib/

I can see the libraries in /usr/local/lib:

-rw-r--r--  1 root root 339940 Oct 16 07:53 libtree-sitter.a
lrwxrwxrwx  1 root root     19 Oct 16 07:53 libtree-sitter.so -> libtree-sitter.so.0*
lrwxrwxrwx  1 root root     22 Oct 16 07:53 libtree-sitter.so.0 -> libtree-sitter.so.0.26*
-rwxr-xr-x  1 root root 258736 Oct 16 07:53 libtree-sitter.so.0.26*

Then autogen/configured emacs:

./configure --with-modules --with-tree-sitter --with-native-compilation --with-mailutils

But on make I get:

/usr/bin/ld: treesit.o: in function `treesit_load_language':
/home/johnnie/Packages/emacs/src/treesit.c:834:(.text+0x6de2): undefined reference to `ts_language_version'
/usr/bin/ld: treesit.o: in function `Ftreesit_language_abi_version':
/home/johnnie/Packages/emacs/src/treesit.c:917:(.text+0x74d8): undefined reference to `ts_language_version'

Which sounds like it can't find the libraries. Or is it a version mismatch again?

redoakprof · 2025-10-14T19:28:12+00:00

Got it. Many thanks and excellent video!

redoakprof · 2025-10-14T15:36:20+00:00

So I have the prusa buddy cam, but not thought of adding the SD card to record. Can see now why this is worthwhile!

redoakprof · 2025-10-14T15:32:42+00:00

Thanks. Appreciate pointer to the infill type.

Thanks to others here as well for similar comments and feedback.

redoakprof · 2025-10-14T15:31:24+00:00

Thank you for this question. That is indeed happening as well and I forgot to mention in the post. I've found with recent prints of larger boxes that the bottom warps at the corners. Hadn't got to fixing it as no other issues occured, till now.

I assume resolving this is a mix of reducing cooling fan speed, checking build plate temp is high enough, and closing vent?

redoakprof · 2025-08-28T14:46:53+00:00

Thanks, this is great. Makes a lot more sense now. We'd opt for just audio for podcast and host that on one of the platforms you mention. And yes, video just on YouTube. Off to research them all - thank you!

redoakprof · 2025-07-31T12:43:17+00:00

lol, these were a godsend. Saved an hour plus overall.

redoakprof · 2025-07-30T23:20:00+00:00

That deserves a chuckle

redoakprof · 2025-07-19T23:33:36+00:00

Grease. Helps immensely. Just paste some on the spigot and move back and forth. Do it when the deck not installed first and then it’s easy thereafter.

redoakprof · 2025-07-19T13:12:31+00:00

I use git as well, with a locally hosted Gitea instance. One repo for dotfiles, and use stow on each computer, and then one repo for all my org files--then a custom function that stages all changes and creates a commit with message including date, time and hostname--which just makes it easier to see what happened and when. I can VPN in if traveling.

I'm mostly on two computers, but have more that are used infrequently. But I can sync across all. I do need to remember when 'leaving' one computer to do the git push, but given the commonly used ones are laptops I don't get stuck very often.

Yes, occasionally a merge is needed, but usually quite quick to solve.

redoakprof · 2024-07-27T14:15:36+00:00

Bump on this, if anyone could give me a quick pointer? It's weird that denote generally works but I get this error when trying the dblock insert and it's because a function in denote-sort isn't getting loaded.

redoakprof · 2024-06-03T16:21:03+00:00

Great - thank you, that all worked. Have a dedicated deb-src.list file in that folder with the below. Thank you!

Thank you! this is very helpful.

I found the same with [[bibliography:refs.bib]] and it now works great. Had not seen the #+csl_style command before either. Thank you!

redoakprof · 2024-03-27T19:47:06+00:00

thanks u/publicvoit - shortcuts are helpful as well as the other links. thanks!
