I’ve got a bit of a fine cut mystery. There is a section of my 3d carve where the fine cut is not cutting deep enough to clear the rough cut lines, but only in one section of the piece. The piece is roughly 12Hx20"W, and the uncut section after the fine cut pass is about 3x6". The section is up against the top Y, but not against one of the L/R sides (image). The bit was fully missing this area (no cutting noise) during the fine pass, but was cutting to the L, R and bottom of the area. After the first fine cut was over, I lowered the z-zero about 0.03in, and reran the same fine cut g-code. It was cutting with a normal cut on the bottom of the carve again, but it missed the top area of the piece again, but on a much larger section. At first I thought my bit might be slipping, but that seems unlikely with the bit cutting to the left and right of the section. Other details: Elite gen 1, 4x4, masso with stand. Cut continuously (no interruptions or pauses). Vcarve pro, 0.06" machining allowance on rough pass, 3d raster roughing strategy. Cutting along X (0 deg) Rough cut = 3/8in square downcut end mill. Fine Cut = 1/8" dia ballnose. Before getting my 3/8" endmill, I used a 1/4" endmill and never had this issue. This is my 4-5th time using the 3/8" bit. Checked coplanarity and flatness of machine. Fishing line test showed that my front left foot needed to be about 0.02" higher. On probing the wasteboard bed, the extreme right side was about 0.012" higher than the extreme left side. Front to back was about 0.004in difference. These things could be a contributor, but don’t seem large enough to explain what’s going on. [image] [image]

What firmware do you have on your Masso?

I don’t think I’ve ever bothered to run an update because it’s given me so few problems. Core v2.04 Software v5.07
