Greetings,   After switching filaments and re-leveling, my printer has decided to no longer home in on the x and y axis. If I position them to home, they only move one direction (opposite of their stop switches). I've tried the common troubleshooting tips such as turning on and off the printer and unplugging/re-plugging the motors back, but the problems still persist.  
Hi guys, We (3D Hubs) will host a conference on 3D printing in education, tonight starting from 8pm CET (2pm EST). The event will be available through online streaming at this link: https://dezwijger.nl/programma/reshaping-science   We've put together a pretty epic line up, including:   Vishal Sachdev (Illinois University at Urbana-Champaign - 3D Printing Specialization Coursera) 
hello, i assembled my printer, turned on everything seems ok. Except my menu on the LCD doesn't have an "Option" choice to calibrate the auto level sensor.  There is also no "Print File" selection either .  With the printer on, placing metal close to the auto level sensor doesn't give me a red light.    Where re can I find real instructions for startup of this printer?
Hi, I've been wanting to buy a 3D printer for a while so a time ago I started researching what 3D printer should I buy   I want it to be overall functional, reliable, able to make great prints out of the box (or after assembly and configuration). I would like it to be able to print at 0.05mm layers for some detailed prints once in awhile and be able to print nylon  
Hey everyone, just wondering if Markforged printers (specifically the Onyx Pro) can print in materials such as PLA and ABS instead of Markforged's proprietary Onyx material.  It would be nice to print in a cheaper material when the part doesn't need to be very strong. Thanks!
MP Mini Select / Hatchbox Yellow @ 190 C
My friend is having continued issues with his MP Mini Select V2.  He gets a few decent quality prints (maybe 3 or 4) in a row, but at some point it appears the Y-Axis begins slipping from a few mm, up to a few cm and he gets a strange stair stepping effect that ultimately turns into a big mess.  (See pictures, hard to describe).    
Hi there everybody, I have a problem I cannot resolve.... in the middle of the print the printer started to underextrude the object. Stopped the print, tried again, but still underextruding... the filament pusher does "stuck" sound. I cleaned well the extruder, also with needle and iron stick from above, it looked like it was solved, but after thirty minutes here again the same thing...
I received a file to print but the STL has some errors in it. The file is build as several squares and triangles placed close together to form a letter ('E'). because the squares are place at an angle of 90 degrees, there is a small gap between them at the corners.
We have a MarkForged Mark 1 Standard that we'd like to sell. We are located in Northamptonshire, UK.   It currently has 40d 0h 12m total print time, for 106 completed prints. Comes with partial roll of carbon filament, and 50cm3 of fibreglass filament unopened. Original box with most of the packing materials, plus the drybox to hold the nylon filament. Original tool kit with flash USB, etc.
