[Q] BTT GD TFT50 v3.0 Maximum Z size greater than 2000 ?

[krys3d]

Hello everyone, I am in the middle of configuring my BIGTREETECH GD TFT50 V3.0 screen with the latest firmware: GD_TFT50_V3.0.27.x and I have a question regarding the size configuration of the machine. Can we put a value greater than 2000 in the maximum size of the Z? Let me explain, I intend to install this screen on an infinite Z printer (an IDEAFORMER IR3 V1) and the maximum size of the Z in the marlin is 99999 which is huge and surely impossible to use, but since it is an axis on a belt that's probably why, but in the config.ini file the maximum value that can be put is 2000 which should be enough for me I think, but I would like to see if there is no way to increase this value.

PS: I do not have the printer yet, it is on the way and I have not yet been able to test by connecting to the machine

Here is my config file :

Machine Size / Build Area

The TFT will auto-detect the machine size (min and max) in Marlin firmware (requires

enabling "M115_GEOMETRY_REPORT" in Configuration_adv.h in Marlin firmware).

Format: [size_min: X Y Z]

[size_max: X Y Z]

Unit: [distance in mm]

Value range: [min: -2000, max: 2000]

size_min:X0 Y0 Z0 size_max:X250 Y250 Z2000

In TFT>src>User>API>config.h

'''' #define MAX_SIZE_LIMIT 2000 // machine size over this will not be parsed.

Thank you, I already tried, but I have a problem with the firmware update. I managed to build the file BIGTREE_GD_TFT50_V3.0.27.x.bin but by formatting the SD card in FAT32 4096 then putting the file BIGTREE_GD_TFT50_V3.0.27.x.bin on the SD card by putting the SD card in the screen and then turning it on I do not have the firmware update which launches, whereas if I look again on the SD card, the file has been modified in .CUR as this BIGTREE_GD_TFT50_V3.0.27.x.CUR so it's supposed to be read by the screen, but it doesn't seem to work

I just tested with another SD card, the one I was using seems faulty. The firmware upgrade was able to be done, I'll see what happens

Thank you for your help, and luckily I had another SD card on hand to test I will throw away my faulty SD card Firmware update is successful with configuration and icons zero errors, perfect

If you have a firmware update problem, test with another SD card of maximum capacity 8Gb formatted in FAT32 4096 Because of this card I was tearing my hair out not understanding why it wasn't working and I was wasting time lol
