Geeetech

Hi again William, One more question: The display on my Prusa is a Geeetech LCD2004. After installing either of the "Marlin-PI3_Pro_B" and "Prusa I3A 2560" firmwares, the 1st and 3rd lines of the 4 line display are dark (see photo). Geeetech display.jpg I see these firmwares have #define REPRAP_DISCO...

Hi William, I looked for the firmware in the link you provided, but none seem to match my 3d printer. I did purchase the printer from Geeetech in January 2015. The invoice from Geeetech says: "Unassembled-Full Acrylic Quality High Precision Prusa Mendel I3 controller board - mega2560 + ramps 1.4 hot...

Hello, I hear from your customer service that you no longer have the firmware for this printer. Can you tell me which firmware is close and and what I may have to edit in the configuration.h file or other files? I tried the pro-B version and the I3A, but the 4 x 20 display just shows blank in either...

Hello, I bought an Acrylic Prusa Mendel I3 with Mega 2560/ramps1.4, with MK8 extruder. I purchased it as a DIY kit in January 2015. I recently modified the printer to allow a higher Maximum Z height of 200 mm. It seems the firmware is still limiting the height to 185mm. I think I need to change the ...

MK8 issue.png I have a Prusa I3 Mendel Reprap from Geetech built from kit, with 1 extruder, .4 mm oriface and 1.75 PLA and ABS filament. I am have trouble with the filament feed, see the attached photo. The filament will not load correctly, it misses the hole in the threaded rod after going through...

I have a Prusa I3 Mendel Reprap from Geetech built from kit, with Arduino Mega, Ramps 1.4, A4988. I have had it only 1 month. the LCD2004 display stopped working. It was working fine, but ow it is just blank. The light comes on, but no characters. I tried pushing the reset button, but it does not do...

Thank you, that helped. But still it seems the prints are bad. I see the E steps is set to 760/mm in firmware. I calculate from the diameter of the extrude gear (approximately 10mm) the E steps should be 200 steps / rev* 1/16 step * Pi * 10 mm dia = 392 steps /mm. Is this correct? Can you send me a ...

I had the same problem. I have asked Geeetech several times for the configuration file, but so far no response. I am very dissapointed. I had the same problem with the motors only going one direction. The problem was the max endstops were triggered even though they do not exist. I put jumpers on the...

My first prints on an I3 look like this. It seems the flow from the extruder is not fast enough. I think the extruder motor is stalling. I tried turning up the current to the extruder on the A4988 but this had no effect. What else can I try?

I bought an Unassembled-Full Acrylic Quality High Precision Prusa Mendel I3 SKU:DPP-06638 with Arduio Mega, Ramps 1.4 and A4988. I have it assembled and it mostly works. The Maximum endstops are not disabled in the firmware. Please send new firmware with the maximum endstops disabled. Or send me the...
