Dear shahin, here are 2 bugs i found in latest ver. in RP3 B+
1. add from usb doesn't show files in flash memory both in NTFS and FAT
2. changing cure time during print doesn't work instantly, needs to stop print and regenerate plate
Offline
1. Could you have access them through putty?
2. Cure time should takes effect instantly.
Do both features were working correctly before?
Offline
1. no through putty i can't see USB (drop down list is empty)
2. cure time doesn't work instantly
i also checked with rpi3B and usb doesn't show
i had no problem in former builds (i think it is 1744)
i also read https://www.nanodlp.com/forum/viewtopic.php?id=654 and checked all comments

what am i suppose to do about usb detection problem?
Offline
Checkout guides on mounting usb disk on linux and possible issues. Because if linux does not mount it, nothing we can do on nanodlp to support it.
Offline
you mean it is a hardware problem? you mean you don't have any problem with usb in RPi3 B+ and this problem is just on my case?

Maybe it happens because of the filesystem (NTFS), will update version soon to have compatibility with NTFS
Offline
no, the problem was due to auto mount usb. i manually mounted the usb.
Offline
it would be your kind, announce here whenever you updated beta build for above bugs.
Offline
Next week we will have pretty large update including this bugfix.
Offline
updated to build 2228, bugfix for changing cure time during print works well, but still flash memory is not recognized both ntfs and fat, as i told you the problem is that it cant be mounted automatically.
Offline
Run setup script see if it makes any difference.
Offline
installed raspbian stretch lite latest ver, ran nano dlp installing script, nothing changed, usb didn't mount
when run "sudo mount /dev/sda1 /media/usb -o uid=pi,gid=pi" through putty, usb files are shown in drop down list. otherwise usb can't be reached.
Offline
Use below command to see if it makes any difference.
sudo apt-get install usbmount
Also check thread see if it is the same issue resolved by the last post.

usbmount is already installed latest ver.
i did the last post remedy, it didn't work.
this problem already exists in nanodlp image file in the nanodlp.com download page both in RPi B and B+.

dear Shahin, remedy mentioned here solved the problem: https://www.raspberrypi.org/forums/view … p?t=192291
just edited /lib/systemd/system/systemd-udevd.service and changed "MountFlags=slave" to shared
now another problem occurs, when i choose the stl file and choose a name then submitting the plate, nothing happens and it stays in add from usb page.

Have you tried different usb sticks maybe it is a issue with specific brands
Offline
I have tried 5 different brand sticks, two rpi3 b and b+, using latest simple installer image, using installing script with stretch lite and tested ntfs, fat formats. Remove and reinstall usbmount. Non of them worked. Finally i could mount the usb and saw files in drop down list by above method, but pushing the submit button didn't respond.
Is this problem just for me? Is the usb works well for you?
