cdru, no, I would have printed that one if I had found it, haha. I guess mine allows for more travel, and has a key to keep the thing from moving side to side, but overall no real difference in use or function. I found yours Ralph, but couldn't figure out how to use it. maybe photos would help?by gm2 - Mendel90
I wasn't really a fan of the slot-mounted y-idler belt tensioner on the nophead m90 - mine kept getting loose and losing tension or getting twisted and interfering with the belt... so I designed a new one. I've been using it for a few days now and I'm pretty happy with the results. Check it out and see what you think.by gm2 - Mendel90
Thanks Nophead, I was worried it was something I was doing wrong. I'll adjust some of the retraction settings and post back if it makes a difference.by gm2 - Mendel90
This is sliced with Cura 14.01. This grey color seems to be the worst for this particular problem, so I'm trying a few different temperature settings to correct it.by gm2 - Mendel90
I'm not sure what's causing them, nor have I been able to find anything terribly similar online. The print is PLA from Prototype Supply, 185C, 70C Bed- .25mm layer heightby gm2 - Mendel90
I am using the default M90 temp settings included by Nophead. 240/130 I've been calibrating the the z-height based on the thickness of the perimeter print. It changed a bit when I first installed the kapton tape but I reset it and it's consistently within .02. The bed level has also been set with a dial indicator to be within a few thousandths across all 4 corners.by gm2 - Mendel90
The bubbling issue seems to have been corrected by adding additional shells to the top. I'm still getting quite a bit of curl on the corners of parts (only abs) though. I've tried kapton, cleaned with abs, abs juice, and hair spray. Some of these make the part stick really well and require quite a bit of prying to remove... but the corners still lift. I've even got an enclosure on the front tby gm2 - Mendel90
great info on the EE steps. I wouldn't have thought of that. Thanks!by gm2 - Mendel90
.1mm layer heights. I calibrated the EE steps during the initial calibration of the machine with PLA. Will this vary with ABS? I hadn't thought about that being a potential cause. Cura slicer - 50mm/s perimiters - 80mm/s infil I was worried that acetone might disolve the kapton. I'll try some acetone now also for the pop offs. The only reason I thought it might be air is that the bubbles aby gm2 - Mendel90
It looks to me like hot air is forcing it's way out of the infill pockets when the printer does the cap layers and thus bubbling out the plastic. This is with Monoprice Black ABS... Best I can recall it was 15% infill printed at 230c with the bed at 110c. Any ideas on how to fix this? I am also having quite a few pop-offs and curls that may or may not be related. For that I've tried extra goby gm2 - Mendel90
No, the PSU fan was coming on fine. In the process of checking the wiring I also re-seated the main power and ground wires on the board, so that might have helped also.by gm2 - Mendel90
Nevermind, left the power off for 30 minutes and quit panic-ing and everything started working again.by gm2 - Mendel90
The print started with the pre-print sequence, then began warming up and went to the z-bottom and front of the build plate then stopped. The printer did not respond from that point forward. I have cut power, pressed the reset switch, plugged and unplugged usb (unrecognized by the PC), and checked over the wiring. Any ideas on how to further diagnose my printer?by gm2 - Mendel90
I was thinking it would be a good place for an LED lightby gm2 - Mendel90
I was just curious what the 2 way connector on the extruder assembly is for? I can't seem to find it in the documentation.by gm2 - Mendel90
