I’m trying to make some game boards that require cuts on both front and back. I thought I had the front side file dialed in and tried making a jig to use for cutting the back. After cutting the jig I realized both cuts are off by about 0.05in which meant instead of fitting together snugly there is about 0.1in of wiggle room. The widest part of the game board should be 3.25in cut using an outside contour path. It’s actually cut at 3.20in-ish. The jig was also supposed to be 3.25in using an inside contour path but came out closer to 3.29in-ish. Then I noticed the 3 circle cuts I added to test for a different project were not round.
Here is the jig file. The other file is too big to post but is the exact same shape/size with holes for game pieces. Pegs and Jokers back jig.c2d (424 KB)
I don’t think the belts are loose, v-wheels seem ok. There is some movement in z-axis that might not be normal.
I ran a few tests of the Hello World file and some of the lines were very crooked, especially around the Carbide logo at bottom center.
From the picture cannot tell if you used a pen or a router bit. If using a pen is it secure. If the pen wiggles so will the line.
Here on the forum are posts about running a calibration. that makes round and diamond shaped objects of a certain size and you measure to make sure the size requested is the size you got. Usually most issues with crooked lines are mechanical in nature. So if an SO3/4 check belts and pulley set screws. Make sure there are no obstructions. If this is new it is not likely a lubrication problem of linear rails but if it is not new or used check on how to lubricate your linear rails.
I tried it using both a marker and pen. The picture is with a pen. Full speed in middle, slowed 30% on bottom, slowed 50% on top. I was testing a theory that the issue would be worse at higher ipm.
The pen made sharper lines and was held securely with carbide’s quick draw pen holder. The marker had the same issue but ink bleed made it look less noticeable.
