Hi folks, I've had issues with the sizes of holes in my 3d-printed parts. I've found it necessary to use a .25mm x-y hole compensation (which widens all hole diameters by .5mm). Without this I need to drill out every hole which works but is a bit tedious and also creates lots of dust that is liable to get into bearings.
The x-y hole compensation works well, except for the J2 motor support, whose hole for the J2 motor is not technically a 'hole' because it is not actually closed (it is split, presumably so i can be expanded slightly). Luckily, there is another setting for this called x-y contour compensation.
On the other hand, I have to turn off x-y hole compensation for the J2 spacer (otherwise the hole is too wide) which is meant to go around the exact same piece as the J2 motor support. So I feel it can't be a systematic issue with my print settings.
I'm wondering if anyone else has experienced this? Does it make sense to adjust the source STEP files?
When printing the structural components I have by default drilled all fastener holes prior to tapping just to make sure the size was correct and the tapped holes were clean. I did find I had more issues on my older low budget ender printer. With this printer in many cases I needed to adjust hole sizes. I had fewer issues on my anycubic and recently I picked up a bambu labs printer and have had no issue with hole sizes on this printer. Im curious, what printer do you have?
