As it turns out, the stepper driver for my extruder was broken. The pot switch maximum was broken so I had no way to tweak it right. When I put a stepper driver from one of my other channels on the extruder motor it worked, but still was skipping steps. I've ordered a more powerful one now and hope that will fix the problem.by Photon - Delta Machines
That's some very useful info. I did calibrate it but I'm beginning to wonder if I used the right technique. I put a line on the filament. I then retracted it 10mm. It then put another line on the filament and measured the distance. I extruded back and forth to make sure it was a consistent length, which it was. I then used the reprap calculator to tweak it until it was right. After heating theby Photon - Delta Machines
You'd say retract_speed has something to say about the speed at which it retracts, not extrudes. In fact, the speed at which it retracts is high, it's the extruding speed that is the problem.by Photon - Delta Machines
Thanks for your replies. The problem seems to shift itself. At first it wasn't extruding fast enough. I don't know how to change the extrude speed in the firmware or slic3r. When I gave manual commands to retract it did get up to speed. I suspected that the reason is that it can't build enough presure to push it through for some reason. I tightened the springs on my airtripper extruder which onlyby Photon - Delta Machines
The part I've been tweaking around in is this: // default settings #define DEFAULT_AXIS_STEPS_PER_UNIT {80, 80, 80, 93} // conversie van stappen naar metrische lengtes #define DEFAULT_MAX_FEEDRATE {100, 100, 100, 10000} // (mm/sec) maximum reissnelheid E was 1000 #define DEFAULT_MAX_ACCELERATION {100,100,100,10000} // X, Y, Z, E startsnelheid #define DEFAULT_ACCELERATIONby Photon - Delta Machines
Hi guys, Just finished the build of a first 3D printer. We've got a Megatronics V2 in it running Marlin firmware with delta mod. I've just switched to Repetier Host whereas before we were using Pronterface. Moving the head goes well. Calibrating that went like a breeze. When I start a printer it first warms up the bed, it then lowers the nozzle to about 5mm above the surface, warms up the nozzlby Photon - Delta Machines
Hi all, We're a team of Dutch entrepreneurs busy with the development of a delta printer. We're aiming to create a more user friendly and aesthetically beautiful printer. We're very experienced on the front of design and business but have a weakness on the software side. We're putting together a team to further develop the printer and plan to launch it mid 2014. We're looking for people experiby Photon - Jobs for people with RepRap skills
