I'm planning to try a tape driven x-axis on my small, but long, router cnc.
I've come across aerosol sprays to increase the friction of rubber belt drives,
but is there one for spraying onto steel tape, or the drive wheels, so that I increase the friction between the two ?
The set up will be to have a shaft coupled each end of the stepper motor driving two tapes directly each side of the gantry, and a pair of presser wheels on each side to maximise the area of tape in contact with the drive shaft. Probably another shaft across the other end with coupled wheels on that.
Another approach might be to change the material of the drive shaft/wheels to something with a high friction surface.
What would be suitable, any ideas ?
