thank you for your replay. I would agree with cable issue, but how come sensor too low or too high? if is in same position always?

HI, I do have issue with auto leveling in ultimaker extended. 1 of 3 times is OK, but other 2 times keeps getting this message. please see pix. Its happen in very beginning of leveling. First ultimaker measure 2nd head, and once it starting move z axis for 1st head it give that fault. but bed has not even touch bed. Hoe to fix or what is the reason ? Thank you

HI, Could you explain why its happening, print started smaller scale and after get slightly bigger, i hope you it can be seen on picture

Also i notice 3D solex core is not working well as well. It start printing all good, but after 30 min or more filament is blocked. Printer shows 200 degree but filament is not extruded. so i took print core from slot 2. swapped with slot 1. That original core is printing with same setting and same filament well. So what is wrong ? temp sensor or heat element in core? I checked temp sensor ohm is about 110.

Hi, Could someone tell e why its fails? Heat cartridge is broken? Also what does mean delta T 20 degree? whats mean i should add 20 degree more on filament sensor ? Thanks

yes sound same , auto leveling can get right height. i did manuly and switch off leveling. it works until i will have to change a core or one of heads.

sorry for later replay, Yes i am running latest software, and would say its happens after update. Automatic leveling not working right at all. if i change head size and let do auto leveling, it will get wrong level, head scratching glass. If i do manual leveling , and switch off auto leveling, it keeps ok until i change head. my understanding auto leveling should get right level itself but it not happening.

how come after automatic leveling 2nd head scratch a bed? its no gap at all. if i did manual leveling as you said 0.1 still nothing. is it possible somehow get in printer to read saved settings for leveling? why it keeps head so low.

hi, I dont understand my printer. i do have Ultimaker 3. I do manual leveling as its asking, 1mm after final calibrating card. after manual leveling i turn rising bed, and its hits 2 nd head no gap between. lets say i choose automatic leveling still hits head after rising bed, what ever i do , its start printing to close, head scratching glass so how to get sorted?

its happening to me as well. filament get blocked in feeder. I event change DDG fedder with 1.75mm gears and still same issue filament not getting extruded from core, or its getting little bit and stop again.

Hello, I would like to ask someone who could give gcode to put in to cura. I need to check filament length being pushed by DDG feeder, so i want to make a mark on filament 10cm above core. i will take start point from tube. So i need right a code in to cura extrude 10 cm filament before its starts print anything, also i need lower bed little bit for this 10cm . Can some one right a code please 🙂 Thank you

have change seeting in cura? you need change printer filament from 2.85 ro 1.75mm as well and after slice it

i found out what is bontech 🙂 so what about core? is nozzle size is no matter?

chuck-yanke Who is GR5? user ? And who is Bontec? 🙂 sorry i dont know do you think is only feeder has to be change? what about head? the hole size inside is about 3mm? is not to big ? Thank you

Why not to make a set for 1.75mm
