Hi Awerby,
I'm afraid you're right, holes won't be accurate without preparing with another tool. I'll start the hole with a plunge bit or at least mill the surface so it's perpendicular to the...

Hi Awerby,

Hi Peter,
Thanks again for your advice. The driver pulley had to be increased from 15 to 18 teeth to transfer the full motor torque to the belt, and I've also added a tensioner to each of the...
Hi routalot,
The 5th axis motor has been moved out of the way. It now integrates in the plate and is indeed one less thing to keep track of. The new version can be found on Github if you like to...
Hi,
Could you have another look at the changes made to the design and say what you think?
I've tried to get adequate force while keeping belt elongation to a reasonable minimum.

Thx Peter,
I've put the calculation for axis accuracy and torque in a spreadsheet and am updating the design to get enough force and accuracy at the tooltip.

Hi routalot, peteeng, awerby,
Thank you very much for your replies!
I've started off by looking at the possible error due to belt elongation under maximum load.
Following calculations use...
Hi,
I was wondering if someone could have a look at attached 4/5th axis design?
The design is made in FreeCAD and does not contain most of the detail yet. The design file can be found on my...
