Carved Text Stepping

[SAA3840]

Any ideas as to why the text on my carve started stepping up towards the keyboard side of the board. I've attached a copy of the .mpc and a picture of the ruined carve. When I try a recarve, I'm going to change the font I used for the large numbers (address). I don't like how it looks. Going to use Black Chancery.
The two roses on the .mpc carved just fine, I cut them off of the ruined carve and then took a picture of what was left.

Check y encoder.

The "Y" encoder is the rotating disc on the rear of the "Y" motor isn't it?

[lynnfrwd]

Yes. Also check belt not too loose.

Lots of burning in the hard wood text, so my thinking is 1. dull bit and 2. the Y gear box bearings...

The Y gears are ok, I checked them today. As for a dull bit, I'll look into that the next time I'm in the shop.
Thanks.

I would say the bit is definitely the problem. It is probably dull, tut it looks like you used a round bit, not a V bit. A dull bit will grab and jump on a climb cut, and with centerline the climb can be either to or away from the keyboard, A dull bit on a raster carve will always jump toward the keyboard side.
