started printing a corner top(non mirrored) last night, completed this morning, issue i have now is the belt tensioner is too tight, and now i’ve got it jammed in the hole,(it is the correct belt tensioner for the piece.etc) and will have to drill it out, since it is too tight can I reprint the tensioner at say 95-98% of original size, to have it be looser? I’m not really sure why the belt tensioner isn’t loose enough for fit the corner top right off the printer tho lol. Any help is greatly appreciated.
When I built my 2 MPCNC Primos, I had to ease the edges a bit. Then they just barely slid in.
I used a tool I have that is a carbide hand deburring tool. Zipped the edges and they fit fine.
–General Tools - Swivel Head Deburring Tool–
Some hardware stores carry them, usually around $12 USD
if you reduce the size the nuts will not fit
reduced the size of the belt tensioner to 98% couldn’t get it to go in the hole otherwize without jamming it slides in nice and the bolt still fits fine
OK then, I wouldn’t have went more than 99%.
Is your printer calibrated good? Seen that as an issue several times. Usually seems to show up when doing the Corner Tops vertical, then the belt tensioner flat. Just my observation.
There are four different tensioners. The last time I saw this issue, the poster was using the wrong tensioner for the corner.
made sure i used the correct tensioner
i got a brand new anycubic vyper about a week ago and just started printing right out of the box
not sure what you mean by is my printer calibrated good? i pulled it out of the box assembled it and started printing things lol
Here is an article explaining 3D printer calibration. I suggest you, at a minimum, print a calibration cube and measure it to make sure your printer is making objects the correct size.
We are not seeing forum posts on this issue, so it is likely this is an problem with either how the parts are 3D printed or how you are assembling them. If the issue is the 3D printer, I have concerns about how other parts will fit. If you have any parts left to print, I suggest you get this issue sorted first.
printed 2 of the trucks so far and the top corner and top corner belt tensioner
fully agree about a 99% chance your printer is overextruding and thats your issue.
Here is a more in depth tuning guide if you want to really dive in.
prints are coming out matching the cura dimensions that are shown when uploading a model, the issue im having is even tho the x, y measurements are correct holes are coming out too small
Ok so you were right it was over extruding… set my flow rate to 90% and my temp to 195 and now the 3/4" emt conduit fits in the leg lock fine
