Wow I just started googling "brass nut mendel90" because I was trying to figure out if the brass nut was somehow bigger than 13mm wide and I just couldn't source the right piece. Well it turns out I also sliced my parts with slic3r! Guess I have to reprint 4 parts now (I was the majority way done with 2 printers), but good to know where my problem was!by Glow - Mendel90
Throwing an update out there for anyone who may end up having a similar issue in the future. Increasing the max_jerk for XY solved my problem. Attached is a side-by-side picture of an object printed with 100 for max XY jerk (left) and 400 max XY jerk (right). Thanks again, Traumflugby Glow - Reprappers
I was also thinking the head was slowing down at each change in curvature Traumflug - Although it's not something exaggerated that I can see just by watching it print. That's why I was thinking accel or look ahead. Currently I have 1500 m/s^2mm/s^2 acceleration and 100 mm/min for X/Y jerk. I was working on bumping up acceleration yesterday but then I had some problems that started slowing me downby Glow - Reprappers
So far all but a couple things I've printed have just been grabbed off thingiverse (that picture included). I'll give a shot at an alternate firmware tonight, it's easy enough. I liked the philosophies I saw with gen7/teacup but whatever ends up working, I'm okay with. Also just so you/others know, I'm using slic3r. I agree I don't think it's the slicing or mechanical issues, I basically figuredby Glow - Reprappers
So I recently finished a prusa i2 I started over a year ago. It uses generation 7 electronics and teacup firmware. It mostly prints great so far. However, on large curves I get small blobs of plastic that in the end give me the appearance of bumpy curves. I've attached a picture. Can someone give me some direction on how to eliminate this? Is it acceleration/look ahead related? Thanks!by Glow - Reprappers
I spoke prematurely. Holding it up to the light for a third and fourth time made me find some tiny solder bridges. At this point if I jump the standby wire the PSU spins up and the LED stays on. I'll post if I have any other problems but thanks a lot for the help.by Glow - Next Wave Electronics Working Group
There does indeed seem to be a short circuit somewhere... Any tips on locating it? Holding the board to the light highlights the isolating traces really well and I don't see any solder bridges.by Glow - Next Wave Electronics Working Group
So I recently soldered together some gen 7 v1.5 electronics. The board was purchased through Traumflug. I started running through the checks here. The standby (yellow) led turns on just fine when I plug in the PSU. However, when I short the standby (green) wire of the PSU the best I could do was get the fan to spin up for a second and then it just shut off again. The green LED (bottom right corneby Glow - Next Wave Electronics Working Group
