Ok, the slightly obsessed, thankfully retired, guy that started this thread will volunteer ... starting at 15 degree increments of the cabin tops! ok so i did 3 prints, just the cabin and a little bit of the bow of the boat. (don't pay attention to the broken parts i had some bad bed adhesion. but it finished the important parts) 1th, normal orientation 2nd 90° (facing the front) 3th 45° (i hope the quality is good enough) its seems the pattern is gone at the 45° angle where none of the faces are almost parallel with either the x or y axis. So that means that the lines you see are actually the motor making 1 step (as it makes 80 steps per unit) and is similar to the anti-analyzing effect.

Regarding the stripes it is strange that this seems to be typical when #3DBenchy is printed via Cura. Hopefully the Ultimaker team will find a good solution. Test #10 - Slicer = Simplify3D. Resulted in zebra stripes! It is starting to feel like the problem is in the boundary where the firmware meets the hardware! i'm edging towards the same conclusion. as the side of the boat is not perfectly parallel to the x axis. it might actually be the resolution of the y-motor we are seeing. That's why the 45¨ boat shows no lines. but still need to verrify

:-o Hopefully Team Ultimaker will keep an eye on both! i'll punish valcrow acordingly :angry:

Good morning guys! i asked around here in the office. and it might be the combin feature that is messing up the surface quality. i'll print some tests with and without them. as well as on the new beta cura. (that might have it fixed already). i'll get back to you on this

I don't want to put to much words into this, but @Daid has the support of a lot of people within UM. I love the forum and the people on it. The idea of a new envisioned forum was not a bad idea. The way it was executed is a different story. I'm hoping and trusting that the people in charge will take the correct decisions. But like Daid said, we started on the forum and we need to listen to it! so please keep on voicing your concerns! The more they hear about the problems the more they will have to act.

yeaah i want the chat back!

can you send some pictures with your story? it might clarify some things.

The Connector might be faulty when heating up. the solder might have come lose, if you have an soldering iron, you can try to re-solder but because of the aluminium this is a tricky process requiring a good soldering iron. Or send an email to support explaining the problem they might send you a new heated bed heater

i want this!!! we should spamm sander about this

the physical ones are

So i will start measuring the friction of the new parts and the vespel ring hopefully this week. we also have some parts made in duratron and other materials. i will check if i can post my results on the tests here in the forum lets see what the tests reveal.

Hi Korneel, i think it's a good idea that you swing by and show me the spacer 3poro has made. Today is my day off and i think i would like to get some more info on the subject myself before talking to you. so i'll make a schedule and i'll contact you with a date so we can have a good talk. is that ok with you?

hi guys i've been quite for a little while because my focus got slightly shifted to another project. (to much to do, not enough people to do it). i'm finishing up this project and i hope to get my focus back on the ring as soon as i can. so no extra results yet. but just letting you know i haven't forgotten cheers

Try setting the invert_x_dir false. But are you using an ultimaker2? or is this for another machine?

i will when i have some more data and results. the tests are running now so i would like to give more information when i can tell you guys a little more with some actual data in stead of just guesses. We have tried a number of ceramics but the things wh have tried seemed not to work because the PLA would stick to it like glue when molten. The trouble is the amount of pressure we can apply on the filament before it deforms/grinds. so we need the PTFE for the low friction. but with the added heat i'm afraid deformation might occur sooner. But as i said, tests are running now and i hope by the end of next week i might know some more

Getting specialized plastics is not easy, so i found a show where they machine vespel and i'm trying to order some rings with different diameters. About the material getting to hot and plugging during lots of retractions. i have been actively cooling the hot-ends with a 35mm fan and fan duct on the front as well. The combination should reduce the overall heat in the hot-end and prevent that from happening. its a work in progress, but i think we are getting somewhere

Daid is on vacation, but i think it was because the ultimaker 2 needs less material settings in the gcode and more material settings saved on the machine itself. that is the main reason i think

Hi guys, sorry i have been a little quiet lately, busy times at the hq. But i have to say i love the work you guys have been doing and i'm very impressed. I'm very curious how the vespel has been holding up. I am actually thinking of ordering some here and running some tests with it for dual extrusion on the UM2, the problem with that is the deformation in the PTFE occurs faster as soon as you add the second Hot-end in the printhead. So actively cooling them with a 35mm fan on the front (and removing the small fan at the back for better airflow). I am however still a little afraid that is not enough to prevent the PTFE from deforming. So thats why i turn to the Vespel. @kris, I really like your idea's with the extra cooling ribs on the steel coupler, and i love your heat simulations. i want to look at your idea as a backup if the vespel doesn't make it as a good fix because it changes more parts in the whole print head. So if you want and can i would really like to your idea's and opinions.

Hi Macua85, if you want to run a dual extrusion setup it is better to indeed use both power-supply's. The new HBK powersupply will be used over spec if you use both heaters and the bed all at once. The hbk powersupply's are very well build so they might just make it. But i would NOT recommend it so you figured out the correct way to do it on your own! i hope you enjoy the HBK!

aaaahhh soo close i'm getting more and more psyched

i'll try to draw up a layout for you (in paint) Edit: the dimensions where a bit off. but i added the production hall and the warehouse

Hmm i like your idea. But the thing is, nobody here has the spare time to draw up the building :(

martijn van gils is the name, ultimaker is the game

I cannot say a lot about this. but the heated bed upgrade will work with all the 1.5.4 and upwards boards. If you can flash the latest firmware to your board, you can install the heated bed upgrade. If you can not flash the latest firmware, you have an incredibly old and rare ultimaker and you should be very proud of it. Because there might only be around a 100 machines out there. The kit might not work out of the box. but being one of the first and having to flash your custom firmware already there is a very big chance you'll be able to make it work.

damm i just found out about this. i'll have a go tomorrow i would like to say a 2 week version is probably better
