# MarlinFirmware
Personal tweaks and builds of marlin 3d printer firmware repositories.
Source code is here: https://github.com/ThomasToka/MarlinbySynman/tree/bugfix-2.1.x-tweakedbyThomasToka
-------------------------------------------------------------------------------------------------------------------
My instructions for firmware installations are:
- level your bed with old firmware
- note your z-offset ex. -1.74mm
- flash new firmware
- connect with pronterface or other terminal to your printer and issue:
- M502 ; factory reset
- M851 Z-1.74 ; set your z-offset
- M500 ; save configuration
- M503 ; check if your z-offset matches
- G28 ; home your printer
- heat up nozzle and/or bed like usually do before bedleveling
- on the touch start autoleveling (there is no need to do the points if your bed was level before..)
- after autoleveling your are ready to print.

Update 23.02.2023 19:47 CET:
Todays update is that there is no update needed. lol
Today i helped some testers, among there was on Ender S1 plus user wanting my firmware to use 300°C.
No problem.. So i gethered measurements from the printer and sent him a version.
He was not able to set 300°C.. My directly thought and after code review verified: "hm thats fishy af. haha, it will be the touch screen firmware!".
We then installed the Ender 3 S1 Pro touch firmware version to break this barrier. double lol.
It works. All other parameters seem also match.
Again one happy person..
I will release a version for the Ender 3 S1 Plus with touch display and the Ender 3 S1 with knob display soon.
I am just gathering some informations and needed measurements. The firmware base is ready to rock also those machines.

Update 21.02.2023 22:11 CET:
Pushed a new update called "performance and quality" update.
- increased buffers as we have enough ram for better sd card and octoprint performance
- rebased on upstream fixes and again manually fixed upstream babystepping that is still not functional with 0.01 mm babysteps
- increased min_segementtime
- increased feedrates for faster printing with "reasonable" barriers
-------------------------------------------------------------------------------------------------------------------
Update 16.02.2023 21:31 CET:
Todays release is mainly a service and quality release.
I fixed babystepping while printing as it is broken upstream.
Enjoy :)

Update 13.02.2023 0:13 CET:
Today i ported all my config tweaks back and released a version of Marlin 2.0.8 with the Ender 3 S1 Pro upstream implementations.
Version 2.0.8 supports also the laser!
I also rebuild my 2.1.2 release and implemented all upstream fixes.
And by the way: I recalibrated my own printers belts which were way to loose :-)
Had wobbles today.. But also with the stock firmware.. Belts tightend. Wobbles way better :-)
Will check deeper tomorrow.

Update 10.02.2023 10:59 CET:
Updated binaries have been released. Its just a small Fix:
The bed is 235x235, standard lcd_rts.cpp, the class managing lcd display only supports integer ex 117. But the bed middle is 235/2=117.5 .
So i had to hardcode it to respect the .5 decimal.
Works perfectly.
Now my firmware is technically complete, besides laser functionality which is not functional in upstream Marlin-2.1.x-pro-s1 source.
So i will have to wait with this till upstream is functional.

Update 08.02.2023 10:42 CET:
It seems there is bug when pushing touch display fast at initial z-offset configuration via touch screen.
I opened a bug with the builder of this wonderfull peace of software.

Update 09.02.2023 10:11 CET:
The touch screen babystepping fast pushing bug has been adressed and (hopefully) fixed. Updated binaries have been uploaded.
Feedback welcome.
-------------------------------------------------------------------------------------------------------------------
Be carefully with your printer. Mine works fine. But this is a new build. So have your fingers near the power button when lowering your z-axis and starting print for the first time.
Please open an issue if there is something wrong.
