Slave axis help

[Duffman]

Sorry about delay Clive.

Pics of gantry motors and limit switches.
Going to wire these on at the weekend, and see what happens from there

Got my home switches all on today but still no joy with my slave axis. Is there something other todo than choose it to be slaved with y in Mach ??

How have you wired them ie have you used two different input pins on the bob and how have you set the slaved axis in Mach3 Also have you set the slaved axis say A or B to linear in Mach. Post a pic of your setup screen in Mach

Fellas I spent a while changing drivers over last night and have now found out that the driver for the A axis doesn't work. Lights are all on but no go, and after what some of you have been saying about them being total crap and not letting me put more than 36v threw them I'm think of up grading them. Have been looking threw the forum and the leadshine am/em series seems to be the way to go would you agree ?

AM882 or EM806 with 68V power supply should be OK if they are nema 23 motors. Not sure about the gearing though you have on the rack and pinion !!

Looking at the pictures you have direct drive and massive pinion size. This will cause you troubles. First the large pinion will give huge pitch size so resolution will be very low.
Worse is the affect of the direct drive with no reduction. You'll struggle with torque and Resonance will be high which could affect motors. The digital drives will help but still your upping there work load which isn't good.

My suggestion is to put minimum 3:1 Reduction using Timing belts/pulleys. This will give more torque better resolution and lower resonance. If not your going to struggle with all those things.!
