Perhaps, but have you actually tested this for yourself?
PLA is extruded at 220C in my Prusa beastie. Once the filament is slapped on the model, I probably want it to to fuse to the previous layer really well and then cool really fast and become stable.
We need to provide working and results rather than “I think that”. My printer is quite close to a very large double doors to outside, which open and shut as required.
“Is this a common issue with samba” - no.
Samba shuffles rather a lot of data, quite happily. You have not given us an exhaustive description of the shoddy wiring, dodgy switches and wonky configuration that makes up your network. If it was perfect, you would not be posting here.
There is one snag with CIFS (Samba follows MS’s standards and ironically, I think that CIFS is now renamed back to SMB) that I am aware of, so SMB … snag: SMB will indicate that a chunk of data has been received successfully but not that it has been written to disc successfully. NFS will notify that a chunk of data has been written to disc.
The difference is subtle but if there is not a battery backed RAID involved then SMB/CIFS can lose data if the system restarts part way through a write.
Your issue is probably hardware related. Test your network with say iperf3. Have a look at network stats. Don’t rely on cargo cult bollocks - do some investigations. Nowadays we have nearly all the tools as open source to do the entire job - we did not have that 30 years ago. Grab wireshark, nmap, mtr and the rest and get nerdy (or hire me to do it - don’t do that please!)
