I currently print at 190c at 50mm/sec and 220c at 80mm/sec at 0.1mm layers, all the pla i use is from faberdashery, i found the pla which came with ultimaker poor and caused issues and poor prints, not looked back since i switched to faberdashery, more expensive but less hassle and failed prints.

I have a similar problem with the Z axis sticking, i have removed the spindle from the steeper, and moved the platform up and down with the smooth rods in place, and even with oiling the bearings are rough. I also find i have issues with prints at the 10mm layer, as the platform drops to 10mm when you start prints etc, so its a common height the printer goes to a lot. It would be good if somewhere you could very the height (eg between 8-15mm) when the platform drops for a test extrude before a print starts, so any wear is varied.

I use this http://www.thingiverse.com/thing:13045 works great at getting under a print.

Just posted the code link http://pastebin.com/download.php?i=9KJ0eyKh to download.

Yep pretty sure its not mechanical as when i unclick enable skin and re create the same code its fine. Let me know where you want the Gcode, and i can send it across.

Hi Daid i might of found a little bug in Cura RC2. What i have found if i have "Enable skin" selected and also have the part rotated using Rot and a figure, after the 1st or 2nd layer the whole print will move to the left by about 10mm/15mm and carry on printing as normal. Noticed this when i took a print off and it was warped on the left side only, noticed you could still see a slight outline on the blue tape which was 1 or 2 layers deep at 0.1mm. The right hand side still had all layers under it so did not warp. Happend a few times until i realised it was the enable skin command seemed to cause it, just did a print with enable skin unticked and printed fine. If you need any gcode etc let me know.

Will give it a go and see what happens but i do check the thumb screw regular, btw RC2 is working fine on Win 7

The above print is already at 220 so i don't think its the temp, i have noticed that on the otherside both prints are nice and smooth, just wonder if its how its sliced ?. I do have the fill overlap at 20 rather than 15 but this has not made any noticeable difference.

Ok this is something which has been bugging me for a while, on the attached photo you can see the marks on the side wall of these parts, with the black the marks are pretty much the same, so its not the pla. I don't think its Cura RC2 ? but i am sure a expert might be able to pin point the possible cause. Even if i print a lot slower and a lower temp ie 195C @ 60ms i still get these marks. Good thing with Cura RC2 is that it save's the setting you used for each print which is handy. Anyway photo and profile used to print these parts below.

I see that this is now available on the Ultimaker website https://shop.ultimaker.com/en/parts-1/ulticontroller-ultipanel.html#

I am on Windows 7, so that explains why the program close's down. Look forward to seeing RC2

Thanks for that, hopefully people will find it handy. Still no joy getting Cura RC1 running, once i enter my filament size and hit next, all the open box's close, and then nothing. Jonathan

Thanks for the quick reply daid, re the used settings i would not want them in the gcode, but in the text file which is generated along with the gcode. Even if it just exported the raw data i guess you could work out quickly what the temp, fill etc was ?. I will try and skip the wizard and edit in the preferences once my current print has finished. Jonathan

Daid, a bit of give and take The give, would it be possible to add to the text file which is generated with every gcode file, basically a exif data of the settings used to create that print, ie temp, fill %, speed etc. Many items i have gone back to a old item and wondered what settings i have used to create that print. As the text file is already created could this data be added ?. I think many people would find this handy The take, i am having problems getting cura up and running, in the start up wizard, i skip the firmware update, but one i get to the section which asks to extrude 100mm of filament i get stuck, it will not allow me to save if i simply enter my mm figure which is 103, (i already have the figure from previous tests) so there is no need for me to run through the whole procdure, but when i enter 103 and then hit save, it changes the 103 to zero. Then if i try to extrude 100mm and try to heat up my machine using the button it heats i hit ok,then i remove the filiment, and line it up, then hit extrude 100mm. but nothing happens. Any ideas?. Jonathan

If you are in the UK, you can get MXL belts from http://www.beltingonline.com/mxl-pitch-rubber-timing-belts-4580 you can spec the width of belt you require, i have used them a couple of times and they ship within a few days and the price's are good so you could order a few spares. I am guessing the 300 on the ultimaker belt is the amount of teeth, so the 2384-MXL could be the right option as this would be about a 4mm shorter belt ?.
