Hi Today, I attached the cooling fan to the extruder. Before that I already had the small hotend cooler constantly running on 12V. I used to connect the hotend fan through the fan- and the spare cable. The spare cable was connected to the 12V AUX of my RAMPS 1.4. And FAN- to AUX GND. Now, I had to reconfigure the cabling. The hotend fan connects now to +12V on (Pin 10, 3 & 11 on the D typeby atmark - Mendel90
It reports following: echo: M92 X80.00 Y80.00 Z3200.00 E543.65 I tweaked the settings as followed 92 X96.00 Y94.00 Z3200.00 E543.65 and now I'm getting almost correct dimensions... While printing I noticed that the belt doesn't glide smooth over the pulley. At one point it lifts up a little bit so the pulley might be china quality. Also I didn't order the belt and the pulleys from the same suppby atmark - Mendel90
Hey I'm using T2.5 pulleys with 16 teeths and a T2.5 belt. Just checked the step settings and they are at 80.by atmark - Mendel90
So I did some testing and printed this model of some squares. Starting from 100x100mm going in 20mm-steps down to a 20x20x20mm cube. As you can see the abbreviations are significant. On the x-axis around 13,5% and on the y-axis around 12%. This test print was sliced with Neil's skeinforge profiles. Frankly, I don't this is a slicing issue. I have an e3d-v6 extruder installed and I'm using it foby atmark - Mendel90
Thank you for your replies. I will look into them closer and report back how it went.by atmark - Mendel90
Hi there Finally I got my Mendel90 ready for printing, the bed is level and everything is adjusted, but still I'm not happy with the accuracy on x- and y-dimension. Lets say I print a cube of 10x10x10 mm the outcome results in a 9x9,5x10 mm cube. And if I noticed it correctly the offset increases the bigger the objects are. Any ideas where to tune the machine?by atmark - Mendel90
