    First problem, and I don't even have the main body of the machine home yet!

    As I said the stepper motors are really nice disc armature ESCAP motors but they are connected to the 16mm ball screws with some very underwhelming belts,

    It seems that these belts are known for shredding themselves at random times. I thought it would be wise to buy some spares, but these are really obscure belts and not easy to find in the UK.

    A close alternative but not exact match is the MXL size of belt, but these have a very slightly different pitch of 2.032 vs 2.073, so it may be necessary to replace the pulleys and the belts to try and standardise and make belts easier to source in the future! I can also increase the current belt width to 10mm from the current 8mm to reduce shredding. If anyone know a source for the 40DP belts it would help!
