I hope Ultimaker team is aware of the lack of feature compare to the price they charge for their products. I also made the switch from UMS3 + Prusa I3Mk3 for the BambuLab X1C. We still have a S5 at work but we are not planing investing in other Ultimaker product at this time.

Can be multiple issues. Start with the calibration of the first layer; if your bed is warped maybe the material is not squished enought against the printing surface causing poor adhesion. Make sure your print surface is clean and/or add gluestick/ 3Dlac/Magigoo.

It works fine for me

Le polypropèlene est "autolubrifiant" et est un bon matériel pour réduire la friction mais je ne suis pas certain qu'il a une grande résistance à l'abrasion. Néanmoins, ce serait le matériel que je recommanderais pour l'application.

When I was printing with PP, I put packaging tape (PP based) on the entire print surface. The printed object fuse with the tape and give a good bonding.

I haven't try POM myself on the excellent Bambu X1C but based on the specs of the Bambu, you should be able to print POM.

I'm using APC 1350VA with no problem. https://www.apc.com/ca/en/product/BR1350MS/apc-backups-pro-1350va-810w-tower-120v-10x-nema-515r-outlets-sine-wave-avr-usb-type-a-+-c-ports-lcd-user-replaceable-battery/ Depending on the print, the UPS can last 15-20 minutes.

Is it because it is replaced by the S7 ?

While you can change print settings to acheive better precision, usualy a 0,2mm gap is required between mating parts to being able to assemble them when printing on a UM printers (My experience is on UMS3 and UMS5). You can get better precision with other printer brands (0,02mm on Prusa I3Mk3 and 0,00 on Bambu lab X1C)

I have both a S5 at work and a Bambu lab X1 Carbon + AMS at home. Before the X1 I had 2 Prusa Mk3 and an UM S3. When the bambu lab came out I rush out selling all of them. In my opinion the X1 is a far better value than anu UM printers. Don't get me wrong I love the S5 and S3 but they sell to high for the performance they bring.

I'm looking formward for the demo. Having a first generation S5 at work (no air manager) that could be a nice upgrade but nothing compare to my personal Carbon X1C from Bambu lab... I would have expect more drastic changes from UM.

It has to do with your setting. I would suggest you use the default to start with. On my system I can open your ptoject and the infill looks good.

I get better results with my S3 and S5 with the default profile. I'll stick to 200°C

Since the printhead needs to move from one column to the other, it might be a ozzing issue caused by the retraction settings not optimised for this material.

Souvent c'est lié au "power recovery". Essaie de le désactiver avant de ré-imprimer.
