Hello all
Can anyone tell why and how to fix this problem?
I was doing an advanced v carve with a 1/8-inch end mill for the ruffing and a Amana RC-1148 Insert V-Groove 60 Deg for the finish. I was having good results for a long time as seen in the pitcher on top.
The other day I went to cut some more stars with the same bits, same software, and same settings, and now the stars are coming out like shit, if you notice they have totally different bottoms on them (i.e) wider. and they also have what looks like an extra cut running down the inside fingers. Does anyone have any ideas on how to fix this?
If a file which was cutting well ceases to, and wasn’t changed, then the cause is electro-mechanical. Things to check:
-
endmill sharpness
-
mechanical aspects of the machine. Per the machine operating checklist: Machine Operating Checklist - Carbide 3D , the basic points of adjustment for a machine are:
-
Pulley set screws: Checking Pulley Set Screws - Carbide 3D — be sure to check all axes/pulleys (including Z on machines w/ belt-drive Z-axis, for an HDZ, check both coupler screws).
-
(for the SO3/4) V wheels / eccentric nuts: Tightening Eccentric Nuts - Carbide 3D
-
(for the Pro) Lubrication of the linear rails: https://docs.carbide3d.com/assembly/linear-guide-maintenance/Linear_Rail_and_Guide_Maintenance_02-17-2021_v1.0.pdf
-
Belt tension (see the relevant step in your instruction manual, e.g., Step 5 Belting - Carbide 3D) Note that the X-axis motor is held in place on standoffs and if those bolts are loose this can cause belt tension issues. Also, belt tension for the Y-axis stepper motors needs to be even/equivalent on each side — a significant difference can cause skipping on one side eventually resulting in lost steps on both. Measuring belt tension, squaring and calibration

or the wiring/connectors — verify that everything is in good condition and secure
Was the roughing bit and the v bit set to same depth ?(or did one slip mid cut?)
