Hi guys just wanted to post a quick troubleshooting guide. Since most issues with the hangprinter are the same. - Heating issues / Overextrusion 1) Calibrate extruder steps. 2) Check wire connections on the extruder end. - If you're seeing temperature fluctuations: 1) Use thicker wires or double the number of wires connecting to extruder heater - Bad connections 1) Crby LordThingol - Hangprinter
Hi Alandaeta. It most probably is a calibration issue. Try replacing the anchor positions with even more accuracy and if it the problem persists try an even older version of marlin (https://github.com/tobbelobb/hangprinter). You can also test individual motor movements using the G6 A,B,C,D #number# command. Sometimes there's some motor skipping steps on long moves (if you're not using mechaduby LordThingol - Hangprinter
Hi Lucernario. Yes you can build a hangprinter v3 without mechaduinos. I finished building mine about a month ago and you can achieve really excellent results. In my case i can print a 1:1 scale benchy without messing it up and a 20 mm calibration cube with less than 1 mm error. Seeing that i plan to use to print big, thats more than enough. In the particular case of the wires, use dyneema not nby LordThingol - Hangprinter
Ok tks. I'll sanity check the line lengths and mounted lines. Maybe thats the issue.by LordThingol - Hangprinter
Yep. I did the measurements as recommended in the Chris Riley build videos (part 2 and 3): My anchors are nailed to a wooden floor and the AY,BX,BY,CX and CY were measured against the mover on the floor level, then i set up the build plate (small wooden board) and zero'ed the extruder to the board. From there i did the ABC-Z measurements from the top of the mover to the floor (,not the board).by LordThingol - Hangprinter
Hello again guys. Finished building my hangprinter v3 without mechaduinos and i've spent the last week or so just fine tunning it. The major issue i'm struggling with is the calibration and precision of the extruder movements. The best i've achieved is a 5% error on the X axis and 12.5% error on the Y axis. So i'm looking for tips into improving this, especially the y axis offset. I've been teby LordThingol - Hangprinter
Update on the D motor issue: #8 Checked ramps pins connection with a multimeter for the E1 extruder (where D motor was connected) - All worked. So ramps was good. #9 Tried Torbs advise: M17 to force enable motors. Nothing happened. Delved a bit deeper into the issue and tried using the M18 and M84 commands, neither was working.. All motors kept having idle torque. So i tried messing around withby LordThingol - Hangprinter
Hello guys. I'm new to the forum and i've been trying to build a hangprinter v3 without the mechaduinos (kinda scarce and expensive). The issue im kinda struggling agaisnt is that my D motor isn't responding to gcodes commands, namely the G6 D5 ( testing if it spins or not). All the other components have been tested and work. So i'm kinda at loss here. System: Mega 2560 + RAMPS 1.4 (A4988 driverby LordThingol - Hangprinter
