    Printing with PLA is fine however, 9/10 of the time when I print with ABS the filament would stop extruding on the first layer. It's not actually clogging, just not coming out because I can still push on the filament and it will come out again. What is happening is it is getting stuck and then the extruder keeps cutting into the same section eventually gouging out that part of the filament and so the filament will no longer move. Does anyone know what is causing this? I am using an E3d hotend and I tried increasing the nozzle temperature to 245 but that didn't help.

    I'd suggest a sanity check of the od of your filament. Is the hobbled bolt clean, spring tension correct? Can you manually feed with the large gear or does that cause issues as well?

    I can manually feed with the gears. It works with PLA and sometimes it works with ABS but not usually. The tension should be fine as I can manually extrude it.

    In my limited experience, ABS is softer than PLA so too much back pressure will cause it to gouge out. I'd try raising the extruder just a bit on the first layer or increase the extruder temp.

    I would try a slight adjustment to see what happens, I typically finger tighten my screws around my filament. This works pretty reliably for me.

    Something you could also try is lowering the speed.

    I run an oiler on all my filaments ... I don't know if it helps or not but sure doesn't hurt lol

    That is odd behavior for ABS.Normally the only thing that would make ABS hard to extrude is too low of a temp.
    245 should be fine, but try 250. Too hot just gets stringy.

    I'm have the exact same problem at the moment. I noticed that my first layer is also in even. I've tried two different filaments. I'm going to try and adjust the z rods later

    Their is another thread on the Robo forums on page 2 with the same issue. It's the slicer update. Try updating matter control

    I am new to all of this. AND I am having the same problem was there any solution to it? It prints fine with pla but has a non feeding problem after about 35-45 mins on a 9 hr project. I have increased my excrud. temp and can feed manually with a static test. Any new updates on this?

    My fira8t thought is to try a different slicer...matter control is glitchy. Start a thread with your issue and if possible a photo
