Talk to GR5 he can help with the 1.75 and U3. Bondtec can make special feeders for 1.75

Has any one tried these guys for bowden tubes? They claim even less friction https://www.captubes.com/

Torgier I love the article! Can you take a pic of how you attached at both ends? Did you get carbon rod on Amazon?

I have been experimenting with not using the tower and using Cura's suggested settings. There seems to be a balance of temperature at the start and end of a print session before it switches to the other print core, this determines how much leaks out when the other head is printing. Is this your experience? In addition the length and speed of retraction also seems to make a difference and is different for PVA and PLA. Do you ever modify them?

Thanks Kman. Are you using the standard .4 nozzle? Just to confirm and the standard ultimaker setting that come in Cura?

I to have been struggling with the tower also and it breaking off part way up. It seems like such a waste of material and time to increase the size and wall thickness to keep the tower from breaking apart. kmanstudios I have seen you post a couple times that you do not use the tower. Could you give us a couple hints how you do this. When I lower the temp the nozzle sometime freezes and the retracts do not seem enough.. I know i am missing something in set up or settings. Thanks in advance

How do you decide what temperatures to use for a new filament? Not just the print temp but Inital Final Standby is there a print file you can use or just look at Ultimaker products that are close?

Attached are two pics of two twin towers next to each other. This is the first time I have seen this, what can cause it? Details: U3 Core 1 Maker Geek PLA , .6 nozzle, layer .15 layer, 1.75 mm filament Print temp 225 Initial temp 230, Int print temp 215, Final temp 210 Core 2 Ultimaker PVA, .4 nozzle, layer .15 layer, 2.85 mm filament Print temp 220, Initial temp 225, Int print temp 210, Final 205 Could this be a retraction issue?

Thanks for help. It worked just like you said

I have a U3 and a 3D Solex AA core with a .6 nozzle on it. How do i tell Cura i have a .6 core? It does not give you that as an option

Having followed this thread from the start I’m confused. Do these chips make prints better or not?

Neotko What did you use to cool your drivers and how did you attach them . Could you take a picture? I have a U2+ and would like to upgrade it. thanks

I have a Ultimaker 2+ with Tinker firmware and Cura 2.5. "Pause at Z" works once but the second time it does not stop. Is there a minimum space between the "Pause at Z" usages. or have they still not fixed the software so you can use "Pause at Z" twice in the same model? I also noticed there are two other kinds of Pause at Z one for BQ printers and one for Repetier should I be using these?

Strange i have bought over 20 spools from MakerGeek with no problems over the past 2 years. Mostly PETG and some PLA. All print great. I know they have had some growing pains. They extrude all their own stuff and sometimes get behind. I would still suggest you should try them. Normally good pricing

I changed all my printers over to Bondtech extruders and have no problem with flexible materials. The current standard U2 and U2+ extruders have challenges with flexible materials. This is not the cheapest solution but it works. http://bondtech.netmine.se/en/start/
