I am trying to assemble the CNC, I did not find the recommended motors. for this I bought 12V 1:17, a chain with a link of 12.7mm. the number of steps per revolution of an asterisk is 11 * 17 = 187 steps.
When I enter all the parameters in the program settings, the motors will be selected and the program will give an error
When I leave the standard parameters - everything works fine - but instead of one turn of the asterisk - I get 10.7 turns.
Is it possible to adjust the number of steps programmatically, or is it easier to make an additional gearbox?
