The modularized design makes it easy to build the printer in 3 steps. Its classic blue and black color combo imparts a touch of simplicity and excellence, embodying Geeetech’s commitment to quality products.

With its build volume as 255*255*255mm³and the classic Prusa I3 3D printers’ gantry structure, A20M makes the best of the building platform and enables you to view the printing details in 360°. Printing at the accuracy of 0.1mm, it delivers objects with smooth surface finish, clear angles and strong structure. Besides, A20M comes with filament detector and break-resuming capability, greatly enhancing your 3D printing experience.

Its well-designed extruder greatly reduces the risk of clogging or leaking. A20M extruder cover features 360°ventilation design, greatly enhancing the dissipation of heat and guaranteeing excellent printing quality.

    I bought this machine for my PhD Project to study the gradient in multi material and i think its gonna make me fail, every few prints the hot end get clogged not only the nozzle but the whole hot end, except that, the extruder is terrible, wanted to try buying the hot end for A30M and install it on A20M but seems it non-beneficial

    • Geeetech Staff   |   05/23/2022

        |   reply

      hello, A30M hotend can not fit A20M . for clogging problem , 1)The biggest possibility is that the Teflon tube at the hotend is not inserted to the end/deep bottom , resulting in a gap.  When the material is withdrawn, it is stuck in the gap and the material cannot be fed. 2)The hot end cooling fan does not work, resulting in the hot end throat is very hot, consumables blocked the throat 3)the drawback distance in the print settings is too large, it is better to be about 6mm 4) When printing one color prints, pls make sure other extruders are also loaded with filaments. which meas no matther what you are printing, pls make all the two extruders are loaded with filaments.  if you print single color prints. pls print with 2 extruders with 50% and 50% for a while , then clean the filament and nozzle.  then start your single color prints printing .  5)The torque of the extruder is too small, you can adjust the stepper driver voltage of the extruder, suggest 1.2V

      How to check extruder stepper motor voltage and adjust it plz?

    • Geeetech Staff   |   06/27/2022

        |   reply

      The PCBA driver on the motherboard has an adjustable point positioner, which can adjust the current appropriately.

    • Habil Mohammed   |   07/01/2022

        |   reply

      On other types or boards there is a screw can be twisted to adjust the voltage/current, but for A20M V4.1B there is nothing like that so after trying I didn’t find that place to adjust the current?? Can you help please, how does it look?

    Hi, I'm considering this as a next printer, I currently run a trio of Creality Ender 3's but they don't seem to have a dual colour equivalent. I can't see a profile for this printer in PrusaSlicer is there an official one available, I see there's one in Cura but I've moved away from using that. Also is it possible to side mount the spool holders or something along those lines, I have shelf space that it would fit but not with the spools on the top of the gantry.
