Today my printer was ready for the first print. I started the benchy printing with petg but it prints just separated thin strings on the bed. I tried a new vacuum sealed role but same result. I tried it with new role of pla but same result.
Can anyone help with this issue?
Check if your filament diameter fits in Cura! also measure if 10cm of extrudet filament are really 10cm. If not, check your E-steps
Thank you for replying.
I set my e steps 3 times today (nearly perfect length with 686.57) and tried also 1000 without a noticeable change.
The diameter is 1.75 in cura and also the filament.
The extruded filament seems to have some cuts in a irregular distance of about 20 to 40 mm.
Hotend fan runs at full speed, object cooling was off when printing first layer(s).
Nozzle (brass) is 0.4mm (in cura too)?
Any other suggestions?
Thank You!
Did you check the machine settings for the Extruder in Cura? Johannes and me had that problem aa we setup our printers with klipper
Extruder 1 (T0):
Compatible material diameter: 1.75
Nozzle offset x/y: 0
Cooling fan number: 0
That's all in my settings. No g-code in Extruder section.
@Martin Bahmann dann… and you checked, if 10cm of Extruded filament really are 10cm? Can you send a picture of a print? Also consider setting your Extruder stepper current from Makertechs 340mA to at least 500, better 600. that caused problems in my first attempts with their Marlin firmware
This was my last print. First layer with 120% but just the brim was printed fine. Some layers higher the print looks good and after some layers the same thin strings.
I tried to change the current to 600 (M906 T0 E600) but after this my axis moving in random directions. I set it back but the axis are moving random...
I had to stop for today. Hopefully I can get it to work tomorrow.
That seems like a temperature problem to me. Try printing with 10-20 degrees more. It might be that it is much lower in temperature that what you are expecting
Ok thank you. I'll try tomorrow.
