I did these little boxes a few weeks ago in both hardwood (teak) and in soft wood (pine)
The " missed steps" occur in the same place in both materials.
The “missed steps” have only occur on these two boxes and not on any other carvings in both hardwood and soft wood since.
I keep my xcarve relatively clean , v-wheels cleaned most days…I have a good dust removal system on the xcarve which keeps the machine, kind of clean
I used loctite where i thought appropirate and I don’t think any thing is lose. As i use small bits (1.5, 2 and 3mm) when i use Easel, I use their conservative feed rates. When i use Vcarve I turn theirs down to an extent that I am happy with and not break the bit
I flick the belts once a week, mainly for peace of mind to hear if the belts are tensioned.
but as said, previously, the machine runs normal on all other carves, except those two boxes.
I think i am accepting Kimberly’s advise and I will go back in, when I have time, and do a carve on one that is not resized, and see what happens.
Thank you all for your advice…it has been a good discussion and you have shown me other things to think about
