My instructions for firmware installations are:
2023-02-08 21:48:18 +00:00
2023-02-27 19:24:32 +00:00
- check your chip inside your printer (look at the about page, usually you will see F4 in the number FW/Ver field)
- for F4 printer create a folder STM32F4_UPDATE on your 4096 formated SD card and put my firmware bin file inside
- for F1 printer it is sufficient to put the firmware bin file inside the root of your 4096 formated SD card
- reboot printer
Note:
Touch display firmware 1.0.2 or 1.0.3 is required. Look at your about page "Screen VER"
But if you have the recent vendor firmware running you should have already one of this touch firmware versions installed and be fine.

Please check your machines start gcode.
Your bed starts now at x=0. Some Slicer default to a negative purge line start point ex x=-2 or very close to the bededge ex x=0.1.
Put it on x=5 or something reasonable beeing good placed on your bed..

My instructions for Z-Offset quick setting and installation:
2023-02-08 21:48:18 +00:00
- level your bed with old firmware
- note your z-offset ex. -1.74mm
- flash new firmware
2023-02-08 22:12:52 +00:00
- connect with pronterface or other terminal to your printer and issue:
2023-02-08 21:52:07 +00:00
- 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
2023-02-17 00:06:22 +00:00
- heat up nozzle and/or bed like usually do before bedleveling
2023-02-08 22:08:36 +00:00
- on the touch start autoleveling (there is no need to do the points if your bed was level before..)
2023-02-08 21:52:07 +00:00
- after autoleveling your are ready to print.

Alternative method for Z-Offset setting:
2023-02-24 19:16:51 +00:00
Do it your way as usual. You can set your z-offset by gcode, by touch display, by other terminal. However you do it.
This firmware is installable as every other firmware.

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.
