We received the S5 a little over a week ago and have had it printing a variety of items primarily to get familiar with it and now have a few items that we need some help with and or clarified.
So as to be clear; we have performed the manual bed leveling and the xy calibration.
Item 1.
Initially we connected via LAN and it was simple and caused no issues; we did a MAC IP assignment so we could monitor the activities off sight.
3 days ago we disconnected the LAN and connected via WiFi as ultimately this is a requirement. Once again we did a MAC IP assignment and all connected and seemed to be fine with us being able to send files via the network and monitor the print when off sight however; when the print completes and the S5 goes into sleep mode the WiFi connection is lost and the control screen on the S5 states; "unknown" network" and the only way we were able to get the S5 back on the WiFi network was to reboot the S5. Initially we thought this was an anomaly however, it does the exact same thing every time. In fact, if we are in Cura we also have to reboot Cura after the S5 is on the network or it only gives us the "Print from USB" option. How do we fix this as the S5 is in a temporary place at the moment but needs to be moved where we do not have reasonable access to LAN. I read others sharing this same situation when the S5 was initially delivered however, I was told not to worry because it was corrected. I also discussed the idea of placing the IP on static as I read of at least one other person having done so with the assistance of Ultimaker. I was told that this can be done and is planned as a menu option in a future FW release but was not given an easy way to do it. I do not know if because the S5 is MAC IP assigned that it is causing an issue when attempting to grab a IP address from the DHCP pool; all I know is that we require a stable and consistent WiFi connection on the same IP address. as such need some help.
Item 2.
Several times the active bed leveling was not able to be completed stating; "There is a Problem with the Active Level Sensor". The bed was clean and there was no material protruding from the Print Cores. Each time the print was aborted and restarted and both times with no intervention from us the active bed leveling was successfully completed; why?
Item 3.
We have printed a few test cubes because we were finding that parts that required being fit together required significant post print work.
Z = 20mm, X = 20.25, Y = 20.22. In every test print the results are pert near the same with the Z always incrementally shorter; now I understand plastic and thermal differences so I ask; would a tweak with shell horizontal expansion mitigate this or am I chasing the impossible? Furthermore; is the shell horizontal expansion value even the correct place to consider?
Item 4.
When we swapped from a .25 AA Print Core back to the original .4 AA Print Core and loaded Ultimaker silver PLA it presented an "silver metallic incompatible material warning"; we proceeded to print with it and saw no issue. Why the warning?
Item 5.
PVA. using the default settings our initial results were less than stellar with the PVA support looking very messy; stringy, spaghetti looking corners, etc.. I spoke with a person at Ultimaker about this and he suggested three things; "always use Prime Tower", use "Grid" pattern for support, and increase "Support Horizontal Expansion to 3mm". We did this and then completed a couple multi day prints and the results were better but still far from crisp. I ask about this because the Ultimaker videos that I have watched show a "much" cleaner PVA support results.
Thank you
