Cheers, though its a toy compared to some of the beasts on here (looking at you chaz!). Don't have any drawings, what are you after specifically?
Rob - ta!
I noticed today that I've had a bit of a design snafu. My motor mount model was mislabelled - the model is a mb10-c and what I have are mb12-c.
Thankfully I caught it before I made the x or z parts, but it means my ball screws are 3mm too low at the motor end as the mb12-c is a little taller.
So options are:
- Buy 2x MB10-C (bad... about £60 each and it isn't great for consistency)
- Re-machine a new front face plate with the ball screw bearings moved down by 3mm (I'll have to order more aluminium... not great but cheaper than two new motor mounts). Will also require a small design tweak to the ballnut mounts.
- skim the motor mount plates down by 3mm. Downside is they were only 10mm to start with so would be getting a bit skinny.
I'm leaning towards option 2. Really annoying - good lesson to verify all models are correctly labelled before using them! Could be worse, at least I caught it before it caused problems on all the axis.
