Houston, we have a problem… it’s what I found after a working hour about… Kossel, pla 1.75, 195°C, 0.15 layer, travel speed was settled to 80 mm/sec, I’ve set 60 now, may be some loss steps, because of too much travel speed, do you agree?
Yes, probably start at 45-50 mms
I use a travel speed of 130mm/sec. not sure what your doing?
I used that speed too, then I tried to reduce it, I’ve set 60 now, but the problem still exists. So I have to think the problem is elsewhere, I suppose a randomly problem in filament’s extrusion…
Om not very familiar with kosel machines but it does look like you lost steps on one stepper motor. Check the voltages on the potentiometers
All voltages are set to 0.534 V, corresponding to 1.7 A limit current about, the chips have a cooler on and a fan working upon the board… I think to exclude an electronic problem, I saw the resulting work is because of a steps losing, but I think now about a filament problem, generating lost steps, I hoped to find someone having a such problem
