Denford Triac VMC with ATC Conversion / Fix

[Chaz]

So, not a trick question .... but would like some confirmation of what my X and Y steps should be. I have it very close but Id like to know how the number is calculated. I know the formula, but on the current info I have, the 725 value does not look correct.

The issue is that I dont know the config of the drives. I do not have access to them and therefore there could be a host of different 'steps per rev' measurement. could be a number of values.

So If I take some of these, I cannot match the value that I am currently using which is 725. This seems very accurate, I am getting measurements within 1% but I need to do more testing. I may have a bit of backlash which *might* account for some inaccuracy, certainly on my Y.

Please see the table below. I take a number of options and nothing matches 725. I then swap the gear ratio around and the closest I get is 819.2.

The third table (in green) I simply reverse engineer from 725 and get some random steps / rev, could either of these be correct?

The claimed maximum output from the driver manual is 1024, but am aware that this could be multiplied by 2 or 4?

Thoughts?

Thanks
