Reducing the space in my garage.

Great number Eddy. Your log is one of many logs I have been reading )

So after further research I found this website:

http://www.orientalmotor.com/support/motor-sizing.html

The numbers offer a guide to the amount of torque required to move at specific feedrates.

The issue now is what will the available torque curve will actually look like. I am unable to get hold of the torque curve for the motors I have in mind ( This is fine, as the torque curve is stepper specific ... so I have read.

On the X-axis – if I remember correctly, I have a theoretical ratio of 1:10, required v’s available. In practice, when testing the X-axis using an oversized drive pulley and a poorly tensioned section of belt, one side worked really well, the other was satisfactory. As the belt was being held in palce without correct tension this was a good result. A confidence builder! Once the pulleys and belts are in place, I can run a second test, adjust etc and then attach a line and weight to the gantry and let gravity tell me how much force is required to move the gantry, in particular the friction coefficient.

Steppers, after bit more reading, I realised this isn’t the place to start when thinking about building the circuit ) I need to be thinking in terms of ripple, electrical noise, and clean/dirty sides of a circuit.

Stripping back on some of the technical detail, I think I need to focus on segregation, shielding, filtering and then follow best practice, as detailed within the document and many of the build logs. I will write something up, best way to avoid mistakes.

As per the second link, it looks like Leadshine is ‘the’ brand and they offer an anti stall feature, which is important feature when slaving motors on such a light rail.

Next steps, take the frame apart and PU the mdf. Order a few non-essential elements, write up the outline for the electrical circuit, order the pulleys and belt.
