OMG!!!!! It was Mattercontrol 1.6 and my old ass computer (64bit win7 athlonx2)usb not able to send data fast enough but 1.53 works fine. Damn there goes 1 week i'll never get back.

Here's a quick video of problem. No filament, ) 0 degrees tmp set on extruder. neither way makes a difference. eeprom cleared, loaded know good one.

trying to extrude 100mm thru mattercontrol 1.61. Not skipping (??) just pausing then starting.

I can't figure this one out. Rostock max V2 biuld kit from approx 7/16. Machine has been running great except a small endstop hiccup about a month ago. New endstop and printing for several weeks, no problem. All of a sudden, the extruder motor randomly stops and starts. Troubleshoot so far. From ...

I'm pretty sure I finally got it fixed. A retension of the tower belts seemed to have set things right. Been able to calibrate and print. Several tower homes and no errors.

So mhackney wins with the loose belts theory, but thanks to all who helped.

Thanks g. , but I tried that several times and because a tower won't home correctly then it starts a print(actually a tower Cal), it will sometimes crash the printhead right into the bed (I guess because its not zeroing out proper).

Just I'll just have to go through the printer. :>( but I'll check your suggestions first. Thanks for the help!!

Thanks mhackney! Ya, switches act correctly during M119 test and steppers are on correct towers. we built this in April or so and has hundred or more hours of good printing. The only thing new ( I just found out) is my son tried to us the Rostock on his own and didn't home the machine properly after ...

unfortunately the switches all pass will zero fails, they all indicate "open" or "close" as they should doing 30 cycles each. During additional homing procedures, I noticed the Y tower exhibits the same problem as the X tower(but not nearly as often), but never saw the 2 do it together. Of course ...

thanks, i'll do exhaustive tests on them.

Been away from my Rostock Max v2 printer for a couple of weeks and upgraded to mattercontrol 1.6.1 couple days ago. Unit was running fine for the past few months-which I purchased from Matterhackers and have not done any upgrades to it yet. My abs prints were not sticking to the heated bed(no ...
