Verdict: I think I've found an easy way to run 2.85 mm filament.

I got it working with 2,85mm filament, i ordered 26mm Stainless Steel heat break with teflon PTFE tube for 3mm filament ( 26mm heatbreak withe PTFE on aliexpress ) , 

 Teflon PTFE tube OD 4mm / ID 3mm on aliexpress 

 

Have it working for a few weeks now without problems

Hello tinkergnome

I notice when i'm in advanced / expert functions / move axes , as long i do not home the X axe i can move it left right but as soon as i home the X axe i got strange caracters as zero and when i'm go to the right the head don't stop anymore

See picture

With the non Mark2 firmwares everything works normal

[Ultimaker Mark2 - The Smart Dual-Extrusion Upgrade]

Thanks tinkergnome for the fast response

 

I did what you asked

I installed Tinker-MarlinUltimaker2extendedPlus-17.10.1 factory reset then did the buildplate calibration everything went normal i then installed Tinker-Mark2-extended-dual-17.09 ( i have the mark2 expansion board disconnected and connected the second head directly on the main board) i did NOT do a factory reset and checked all the prefereces settings but it looks normal. But when i choose raise buildplate in the display the buildplate raise very slooooooooow, like 1cm in 1 minute and when i choose to adjust nozzle (1) the head goes right in the wall and not stopping

Hello i hope someone can help me

 

I've got a Ultimaker 2 V2.1.4 control board (clone) with the tinker 16.03.1+ / 17.02.1+ or 17.10.1+ firmware everything works normal but when i install a tinker-Mark2-extended firmware don't matter witch version ) 17.02.2 or 17.06 or 17.09 and a factory reset when i calibrate the buildplate the buildplate goes up and then the head goes to the right but it don't stop it crashed in the right wall and it don't stop, i have to switch the power off.

When i turn it on again i still have to do the calibration steps again and a soon as the head moves to the right it won't stop and crashes in the right side wall again. If i go back to the normal tinker firmware (17.10.1 or older) everything works like it should, normal calibration.

Also with the normal tinker firmware with S3D  in Machine Control Panel i can control the head like normal but when i flash a Mark2 version and i do not a factory reset i can control the head a few time and then the head crashes in the right wall and don't stop till power off also when i click on the Y+ or Y- the head moves on the X axe not on the Y axe and crash again in the right wall and have to power off

It don't matter with or without the Mark2 expansion board it crash in the right wall with a Mark2 firmware

Apart off the XY movement i can control the heater and fans of the two heads apart with the expansion board connected, so that works normal

 

I hope someone can help me 

[Screen/Input Freezing But Still Printing]

I've got a UM2ext+ and had the same freezes, used tinkergnome 16.08.1 and 16.08.2

Downgraded to tinker 16.03.1 and it never happend again for more than a month now

with several long prints (+ 24H prints )

So i stay on 16.03.1 for now

[Filament Change time to short]

Thanks for the fast reply gr5 and ultiarjan

ultiarjan i checked the e-steps with tinker firmware and indeed it was way off. It was on 262, changed it to 369 what you said and it's working as it should thanks

The other steps are on X=80, Y=80, Z=200 is that correct for a UM2+ extended??

Do i have to recalibrate my Simplify3d settings?

Also because of the wrong e-steps when i loaded a gcode generated with Simplify3d i got a message Error: Tried printing out of printing area and when i loaded i file created with CURA everything was oké , that was with the tinker firmware and with the Original firmware it worked fine with s3d and cura so therfore i stayed with the Original firmware. So now i'm back to Tinker i love the info on the screen when i'm printing

I have also a question about S3D when i have the usb cable connected and i start S3D the UM2+ get a reset and also when i close S3D the printer get a reset, and that's not funny when you are printing, do you know a setting what is responsible for this or is this normal with Simplify3D, it dusn't do it with Cura

Thanks

[Filament Change time to short]

Hello

I've got a UM2+ extended for two months now, but got a small problem with changing the filament

When i go true material/change in the menu the nozzle get warmed up and after a few seconds the feeder pull the filament back, but not long enough so when the feeder stop i see the filament about 20cm from the feeder in the bowden tube, so i have to pull the last 20cm out by hand. And when i put the new filament in i wait till i see the filament by the first bowdenclip and puss the button so the feeder speedup but than it slow down about 20cm before the nozzlehead and than very slowly it moves the filament to the nozzle but that (20cm) takes almost a minute

He does that the last few days after i flashed from tinkergnome 16.03.1 (used that for more than a month) back to the orginal cura 15.04.6 firmware

I hope someone can help me??

Thanks
